One of the most important technical specifications in displays is the refresh rate, yet many business owners are unsure how this choice affects their day-to-day usage. In this article, we’ll explain in simple terms what refresh rate is, the difference between external refresh rate (Input) and internal refresh rate (Driving/PWM), and how to choose the right rate based on screen type and display technology (LCD, LED, OLED, and digital signage). In addition, we’ll present common business scenarios – from an office display or a digital menu in a restaurant, through product displays in stores, to outdoor signage and video walls – and provide practical recommendations for every situation. We’ll understand when the default 60Hz is sufficient, when 120Hz offers an advantage, and when an especially high internal refresh rate (1920Hz, 3840Hz, 7680Hz) is required to prevent flicker, strobing or distortion on camera. The goal is to give business owners foundational knowledge that will help them choose the right screen based on the intended use case, the physical conditions (indoor, outdoor or shop window) and the sensitivity of the audience or the need to film the display.
Understanding Refresh Rate: External (Input) vs. Internal (Driving/PWM)
What is refresh rate? Refresh rate indicates how many times per second the image on the screen is updated, and it is measured in Hertz (Hz). The higher the rate, the less the screen flickers and the smoother motion appears. At a low rate, on the other hand, visible flicker may appear that strains the eye. For example, 60Hz means the screen updates 60 times per second. For the human eye, rates above ~60Hz are typically perceived as stable and without visible flicker.
External Refresh Rate (Input Refresh Rate)
This is the rate at which the video source feeds frames to the screen. In other words, how many frames per second (FPS) the computer, media player, or signage system sends to the display. In most cases, the external rate is 60Hz by default – a common standard for computers, televisions, and basic digital signage. There are also screens that support 75Hz, 120Hz, and even higher, but they will only take advantage of it if the source content supplies a correspondingly high frame rate. A higher external rate makes it possible to display smoother motion when content is fast and dynamic, because the screen presents more frames per second so the transitions between them appear seamless to the eye. For example, 60FPS video will look smoother on a 120Hz screen than on a 60Hz screen, because at 120Hz each frame is updated twice per second instead of once. Even cinematic 24FPS content can look more stable on 120Hz, since the screen can repeat each frame five times (5:5 pulldown) instead of performing 3:2 pulldown at 60Hz, which causes slight judder in motion. However, if the content itself is slow (for example, a slideshow of static images or 30FPS video), raising the screen’s rate alone will not noticeably improve the experience. It’s important to understand that the difference between content frame rate and the display’s refresh rate can affect motion smoothness: frame rate is a property of the video or animation, while refresh rate is a property of the screen, and the two need to be balanced. In summary, the external rate mainly affects the motion smoothness and responsiveness of the screen – relevant when there is moving or interactive content at a high pace.
Internal Refresh Rate (Driving/PWM Refresh Rate)
This is a concept less familiar to the average user, but particularly important in LED screens and in technologies that use PWM dimming. Internal refresh rate refers to the rate at which the screen’s internal electronics actually produce and refresh the image on the display’s pixels or LEDs. In LCD or OLED screens, every frame that arrives from outside is displayed continuously until the next frame (a “Sample-and-Hold” display), so flicker at the refresh rate itself is usually not perceptible. By contrast, in LED screens (such as video walls and digital signage), the image is created from hundreds of thousands of tiny LED diodes that flicker on and off very quickly within each frame – a process known as PWM (short for Pulse Width Modulation). A high internal PWM rate (also measured in Hz, sometimes thousands of Hz) means that each LED diode lights up and goes off many times within each frame, so the eye only sees the average (continuous light without flicker). If the internal rate is low, the viewer may notice flicker or banding when filming the screen with a camera. Therefore, internal rate performance is a measure of the display’s stability and “freedom from flicker”.
It’s important to understand the difference: External rate (input) determines how many images per second are fed to the screen – and affects smoothness and motion quality; Internal rate determines how fast and granular the display itself refreshes the pixels/LEDs – and affects image stability, freedom from flicker to the human eye, and suitability for camera capture. For example, a large LED screen may receive a 60Hz video signal but drive its LED diodes at 1920Hz internally. This means that every frame (out of the 60 per second) actually flickers and refreshes 1,920 times per second at the LED level, so there is no visible flicker to the eye. With such a screen, even if it is filmed with a typical smartphone camera (30-60FPS), the chance of dark bands or flicker in the footage is very low, because every source frame is effectively refreshed dozens of times in hardware. By contrast, an older LED screen with 480Hz internal refresh would cause the camera to see strong flicker, and even with the naked eye slight flicker could be noticed under certain lighting or motion conditions. In fact, LED screens at 960Hz used to be considered “low refresh” and have disappeared from the market because of flickering images and low quality. Today, common levels in the industry are 1920Hz and above, with the standard having moved to 3840Hz in many modern signs and screens.
Why is a high internal rate necessary? Beyond preventing flicker to the eye, the internal rate is critical when filming the screen. Video cameras also operate at frame rates and use an electronic shutter, and if the camera’s shutter “collides” with the screen’s flicker rate, moving black bands or flickers will appear in the footage. The solution is for the screen to refresh internally much faster than what the camera sees. A rule of thumb is that the PWM rate should be at least 30 times the video shooting frame rate. For example, for filming at 60FPS, an internal rate of about 1800Hz or higher is required to prevent flicker. That’s why 1920Hz is considered the “entry threshold” for quality LED screens, and 3840Hz is already virtually immune to any standard camera (most cameras won’t detect flicker at such a rate). Higher rates (7680Hz and even beyond) are intended primarily for special filming scenarios – such as very slow-motion cameras, virtual film productions, or studios that use the screen as a critical background actor. For the human eye, by the way, there is no noticeable difference between 3840Hz and 7680Hz – both are high enough that the eye sees a stable image without flicker. The difference only matters with especially fast cameras or specific technical requirements.
Let’s summarize the theory: the external refresh rate of the screen (for example 60Hz or 120Hz) will affect how smooth and fluid motion appears on the screen, depending on the content’s pace. The internal rate (primarily relevant to LED screens and digital signage) determines how free of flicker and strobing the display is – both for viewers’ eyes and for the camera lens. Now that we’ve understood these concepts, let’s look at how to apply them when choosing a screen for various business scenarios.
Differences Between Display Technologies (LCD, LED, OLED, and Digital Signage)
The screen types common today use different technologies, each with a different mode of operation that influences the relevant refresh rate:
LCD Screens (Including LED-Backlit “LED TV”)
LCD screens (Liquid Crystal Display) are the most common in desktop computers, office monitors, and standard televisions. Most are characterized by an external refresh rate of 60Hz by default, and some more advanced models support 75Hz, 120Hz, and even beyond (primarily for gaming or fast video purposes). In LCD screens, the pixels themselves retain the image between frames (the display is, as mentioned, “sample-and-hold” without flicker between refreshes), so there is no built-in flicker at 60Hz – the image is stable to the eye for most users. The difference will only be noticed if the content is especially fast; then 120Hz will look smoother (less motion blur) compared to 60Hz. As for internal rate, LCD screens do not have PWM at the frame rate; however, the backlight (LED Backlight) in some screens is dimmed using its own PWM. In older or cheap LCD screens, dimming the LED backlight to a low brightness is sometimes done at a rate of a few hundred Hz, which may cause slight flicker to the eye and discomfort for sensitive users over time. Today, many manufacturers have moved to direct current (DC) dimming or to very high frequency PWM (several kHz), and have marketed “Flicker-Free” screens to prevent health issues for employees. Therefore, when choosing an office LCD/LED screen, it is recommended to make sure it is rated as “flicker-free” – which ensures that the eye will not suffer from latent flicker even during prolonged work. The bottom line is that in LCD screens, the meaningful refresh rate is the external one (standard 60Hz is enough for most office uses), while the internal aspect (backlight flicker) is handled by advanced dimming technologies in modern displays.
OLED Screens
OLED technology (Organic LED) is found in advanced televisions, smartphones, and some premium monitors. In OLED screens, each pixel emits its own light without a backlight, so there is no backlight flicker as in LCD. Many OLED televisions and home cinema screens support an external rate of 60Hz or 120Hz, to enable smooth motion in games and movies. For example, many modern 4K televisions already include 120Hz support. The internal rate in OLED is derived from how pixel brightness is controlled: some OLED screens (and particularly smartphone OLEDs) use fast PWM to dim pixels at low brightness levels. These PWM rates are usually high (sometimes a few hundred Hz), but it’s known that for highly sensitive people they can cause eye fatigue or discomfort during prolonged use. Luckily, in most large OLED screens the dimming rates are high enough, or there is a combination with DC dimming, so for the average viewer there is no visible flicker. In practice, a business owner using an OLED screen for advertising or display (for example, a premium OLED display in a fashion store) should focus mainly on the external rate – choose 120Hz if smooth content is required – and worry less about the internal rate, because these screens are inherently stable to the eye. That said, if prolonged close viewing is intended, it is recommended to check reviews to ensure the screen is “flicker-free” even at low brightness levels.
Digital LED Signage (Video Walls, Outdoor Signage, and LED Boards)
LED signage is a distinct field that uses very different technology from LCD/OLED. These are the large screens built from modular panels of tiny LED diodes. Here, the internal refresh rate is a key spec in every datasheet. As explained, the LED diodes flicker and switch on/off at a high frequency to display the image in various intensities. Common rates in modern LED screens are 1920Hz, 3840Hz, and even 7680Hz – numbers far higher than the external rate (which is usually 50-60Hz for the feeding video). A high internal rate ensures the image is smooth and stable both to the viewer’s eye and to cameras. In fact, 3840Hz is now considered the “gold standard” in many LED screens, because it eliminates flicker in almost any standard filming test. 1920Hz is the basic threshold considered High Refresh at the entry level – sufficient for human viewing without flicker, but it may show slight banding under certain cameras–. 7680Hz is an elite refresh rate used for special projects (XR productions, film studios) to ensure zero flicker even when filming at very slow motion.
It’s worth noting that moving between these tiers involves different hardware costs – more advanced driver chips, faster circuits, and so on. Therefore, LED signage at 3840Hz will be more expensive than its 1920Hz counterpart, and 7680Hz is even more expensive and intended for professional niches. Even so, as we’ll see in the recommendations – for many business applications it is well worth investing in a high internal rate, especially if display quality is important or the screen is likely to be filmed. In fact, the rule of thumb in the LED industry is: if in doubt, it’s better to choose a higher rate within budget – for example, 3840Hz, which is a good combination of quality and cost and is suitable for most uses, from indoor to outdoor screens.
As for the external rate on LED signage screens: most controllers and media players feed content at 60Hz, and sometimes 50Hz (for example, European PAL video). In some cases, advanced signage installations or games may feed 120Hz, but this is less common in outdoor signage and advertising. Therefore, 60Hz is usually sufficient as an input rate, and the whole emphasis is on a high internal rate to ensure that content at 60FPS or lower is displayed without flicker.
Now that we’ve distinguished between the types of technologies, we’ll move on to concrete business scenarios and determine the requirements and recommendations for each.
Matching Refresh Rate to Various Use Cases
Below are several common environments in businesses and offices, with guidance on choosing the right refresh rate for each, including practical reasoning:
Office Screen and Digital Menu in a Restaurant – 60Hz is Enough in Most Cases
The scenario: Office computer monitors, lobby information screens, or a digital menu screen in a restaurant/cafe (read more about AI music for restaurants and cafes). In these situations, the content is mainly text, static images, or slow-moving video (for example, slides that change every few seconds, a price list, a presentation, or an image gallery). The audience reads information or watches the screen for practical needs, with no demand for action or gaming experiences.
Requirements: In such a scenario, there is no fast motion that justifies a particularly high frame rate. 60Hz – the standard rate – already provides a smooth enough experience for reading text and viewing basic images and videos. The screen updates every 16.7ms, and the eye sees a perfectly stable image. In fact, 60Hz was the accepted rate for computer monitors for years and everyone got used to it as a “good enough” experience for ordinary use. Increasing the rate to 120Hz will not change much when reading a Word document or displaying a restaurant menu board – the text will not become clearer and the static image will not “flicker” less, because at 60Hz there is already no visible flicker to the eye. Even in video clips shown on the menu (say, a light background animation), most are shot at 30FPS or 60FPS, so they will see no improvement on a 120Hz screen (the frames will simply repeat themselves). Only in rare cases where you want to display 120FPS video in a restaurant – an unusual situation – would there be an advantage to a screen that supports 120Hz.
Internal rate: If we’re dealing with a regular LCD/LED screen (such as a TV or computer monitor) – it doesn’t flicker at 60Hz anyway, and is very likely Flicker-Free at standard brightness. It is more important to choose a quality screen with a stable backlight, so that employees’ eyes do not get tired even during prolonged work. In LED screens (digital signage) used for restaurant menus or small signs inside a business, it is recommended to ensure a sufficiently high internal rate so there will be no flicker: today, 1920Hz is considered the minimum for a display free of flicker for the average person. This rate ensures that the image won’t flicker even when viewed up close, and that incidental phone footage (for example, a customer photographing the menu) will not show prominent banding. In the past, digital menus with 960Hz LEDs would cause flicker that could disturb the eye and even cause fatigue if viewed for a long time. So, do not compromise on an outdated LED screen: require at least “High Refresh 1920Hz” in the spec to get a stable image. Luckily, most new signage screens meet this requirement by default.
Practical recommendation: For office uses and basic signage, a standard 60Hz screen will absolutely do the job. Focus on more important aspects of a quality screen – such as resolution, brightness, viewing angles, and contrast. Make sure the screen is “flicker-free” in backlight dimming (Flicker-Free) to prevent eye strain. If you’re purchasing an LED board for a menu/signage, choose a model with a high internal refresh rate (at least ~1920Hz) to avoid flicker. There is no need to pay extra for 120Hz in these situations – 60Hz is enough and even accepted as the standard for a quality and clear display. A higher rate simply won’t be utilized in most cases, making it unnecessary in terms of cost and operations.
Product Displays in Stores and Shop Windows – The Advantages of 120Hz
The scenario: Screens placed at point-of-sale, store windows, interactive product displays (for example, a monitor showing a video of a rotating product, an animated ad, or even a smart mirror/touch screen for the customer). Here the content is usually attention-grabbing: commercial clips, animations, fast clips of the company’s products, or an interactive interface that the customer engages with. The goal is an impressive viewing experience that stands out among the many stimuli in the store or on the street.
Requirements: In such a scenario, visual motion smoothness can play a role. A screen with 120Hz external rate will be able to display animations and motion more smoothly than 60Hz. For example, a fast video of a fashion model, a car, or a motion-heavy advertisement will look somewhat more realistic and smooth if played at 120FPS on a 120Hz screen, compared to 60Hz. Even when the content is 24FPS (such as cinema/fashion clips), a 120Hz screen can split frames evenly (5:5) without stuttering, compared to 60Hz which may introduce slight judder (3:2 pulldown). This way the motion of the models or product on the window screen will be perceived as more elegant and fluid to the viewer’s eye. Beyond that, the interaction experience and UI motion (for example, browsing products on a touch screen in a store) feels more responsive with a high refresh rate – touch commands and animations happen at lower latency and with a natural flow. This can contribute to a modern and technological impression in the store.
In addition, many premium and large televisions today (lobbies, stores) already include built-in 120Hz support. For example, there are large digital signage models (such as 86 inches) that support 120Hz to enable “smooth content” in a commercial environment. Therefore, sometimes choosing 120Hz is not very expensive if the newer screen supports it by default anyway.
It’s important to note: the difference won’t be dramatic in every situation. If you actually play a 30FPS video on the screen or a slide presentation, switching to 120Hz won’t “create” new information – the content will be transmitted as is. In other words, 120Hz is beneficial only when there is content or graphic effects that can take advantage of it. Even so, many businesses in retail are starting to produce smoother and more impressive video content (even shooting at 60FPS or 120FPS of a product in action) to stand out. A screen that supports this will allow you to display the content without technical limitation. In addition, a high refresh rate may also indicate a sharper and faster panel (with a low response time), so fewer motion smears will appear on moving objects.
Internal rate: In a shop window or product display, the screen may also be a large LCD/OLED or a modular LED screen (for example, in luxury stores, a bright “LED wall” is sometimes installed instead of a television to overcome sunlight in the shop window). For LCD/OLED – there is almost no concern about internal rate as they don’t flicker in the classical sense. It is recommended to ensure the screen is of high quality and there is no backlight flicker (again, choose Flicker-Free). For an LED sign/wall inside a window – it is recommended to aim for an internal rate of at least 1920Hz, and if the budget allows then 3840Hz. Why? Because in a shop window there is a high probability that people will photograph the display (customers share on social media, journalists film image features, etc.). 1920Hz may still create slight camera banding under certain conditions, while 3840Hz almost completely resolves this. In addition, 3840Hz will give a smoother transition between animations and flicker patterns – the image is “as stable as a TV menu” even when viewed from the side or in motion. According to industry classification, 1920Hz is sufficient for basic retail signage and budget-constrained projects, but 3840Hz is recommended for modern advertising screens that want quality without compromise. Remember that lighting conditions in the window (direct sunlight, for instance) sometimes require high brightness levels in LED screens, which can accentuate flicker if the rate isn’t high enough – yet another reason to choose an advanced spec when possible.
Practical recommendation: For product displays, in-store signage, and shop windows, it’s worth considering screens that support 120Hz to achieve smooth, eye-catching motion. Especially if you plan to display rich or interactive video content – 120Hz will ensure that the screen is not the limiting factor. In terms of the screens themselves: most new large 4K televisions already support 120Hz, so choosing such a TV for display can be an excellent solution (make sure it’s real 120Hz and not just a simulated “motion smoothing mechanism”). If using a LED wall or digital sign in the store, it is recommended to choose panels with 3840Hz internal rate to give the smoothest and most stable result – that way the product video will look great both to the eye and on camera. In case of a limited budget, you can also start with 1920Hz (sufficient for most regular signage needs), but take into account that this may slightly limit the camera quality of the screen. The bottom line: 120Hz (external) is not absolutely mandatory – a quality 60Hz screen will still do a good job for ordinary content – but it is definitely a “plus” that can upgrade the level of your store presentation, if the content and conditions justify it.
Outdoor Signage, Event Video Walls, and Studios – The Need for an Especially High Internal Rate
The scenario: Here we’re talking about the most demanding cases in terms of refresh rate: large outdoor digital signage (such as an LED billboard along a road or on a building), giant screens at stage events (concerts, conferences) used as video backdrops, video walls in TV studios or productions (such as a virtual set), and display screens in large showrooms or museums where quality must be uncompromising. The common denominator for all these is that professional cameras or large audiences viewing over extended periods are usually involved, as well as very large and bright screens.
Flicker and filming challenges: In these scenarios, any small flaw such as flicker, side banding, or strobing can be devastating – it will stand out to the eye or be recorded by high-quality cameras. Suppose a video wall is behind a presenter in a TV show: if the screen’s refresh rate isn’t suitable, the camera will broadcast flickering black bands across the backdrop to millions of viewers – unacceptable in broadcast. Another example: an advertising board at a sporting event being filmed – TV cameras will record it in the background, with no room for flicker. Even at concerts and festivals, audiences today often film clips on smartphones; an LED sign that flickers in their footage will create a negative impression. Therefore, the requirement in these scenarios is a very high internal refresh rate for the screen – usually 3840Hz at the very least. In fact, 3840Hz has become the standard in the events and studios industry because it is above the detection threshold of most cameras: a 3840Hz screen will be “flicker-free” in almost any normal video recording. Moreover, it provides a stable and clear image to viewers’ eyes even up close or over hours (without the risk of fatigue from subliminal flicker).
In leading projects, especially those involving slow-motion filming, cinema cameras, or XR environments (virtual/augmented reality in a studio), the standard rises to 7680Hz internal and even higher. This rate ensures that even cameras with an especially fast shutter or 120FPS+ shooting will see no flicker effect – the screen renders every frame hundreds of times before the camera captures it. For example, in modern TV studios and virtual sets (such as those used for film productions with LED backdrops), it is customary to use LED screens with 7680Hz along with special camera synchronization to get a perfect image without artifacts even in demanding filming conditions.
External rate: In most outdoor signs and stage screens, the video content itself does not exceed 50-60FPS (regular broadcast or standard video content). So 60Hz as an input rate is sufficient. In rare cases, in extreme installations, 120Hz external may be used (for example, special simulations or computer games at an eSports event on a large LED screen). But as noted, the truly critical part is the internal PWM. Of course, in event display systems response time and zero latency also matter, and a high external rate can slightly reduce input lag – but this consideration is negligible compared to the flicker and filming issue.
Practical recommendation: For projects involving outdoor billboards, stage screens, and studio screens, no compromises – look for LED screens in a High Refresh spec of 3840Hz and above. Today almost all major manufacturers offer 3840Hz as a default in professional signs, and even recommend it as a rule of thumb for indoor and outdoor conditions. The added cost is justified: you’ll avoid “video flicker” that hurts content quality as well as viewers’ eyes. If you know the screen will be part of very professional video productions (for example, an LED screen integrated as a scene in a film, or a screen in a high-end showroom where commercials are filmed), consider upgrading to 7680Hz or specifically ask the vendor about models with “Ultra High Refresh” rates. These technologies use special chips to achieve the high rates, so they are expensive – use them when you truly have a professional-technical need. For example, a display expert in a TV studio will confirm that 3840Hz is enough for most HD broadcasts, but for high-speed filming in a cinema studio they will install 7680Hz for margin.
On an outdoor billboard facing drivers or passers-by, 3840Hz is an excellent choice because it also prevents flicker that may distract drivers or fatigue viewers at night. Don’t forget that outdoor LED screens are also sometimes viewed through the phone cameras of audiences – for example, tourists filming signage in a plaza – and you want your brand to look sharp and clear in the footage too (without strange effects).
One more point: if the budget is very limited and you’re hesitating about whether to upgrade to a high internal rate, think about the nature of the use – if there will never be professional filming of the screen, and the audience only views from afar, you may be able to settle for a 1920Hz model with no visible problem. But remember that today the gaps have narrowed and advanced screens are becoming standard. 960Hz screens are no longer recommended at all (due to “flicker and strobing that cause low quality”). 1920Hz is basic, 3840Hz already provides peace of mind in most scenarios, and 7680Hz is for peak professionalism. If you’re an event production, rental, or studio company – you’ll probably go straight to 3840Hz as a minimum to match your customers’ demands.
Summary for advanced scenarios: Investing in a high internal rate is essential to prevent flicker, strobing, or distortion on camera. This ensures that your content will look great from every angle – to the eye, on the TV camera, and on the smartphone of the audience member. By contrast, there is no point in an excessive spec that isn’t needed: for example, there’s no point in a 240Hz external screen (which exists mainly for gaming) for an outdoor sign showing 30FPS clips. Instead, focus on the internal rate of the sign. Generally speaking, a high refresh rate is a blessing when needed, but unnecessary when you gain nothing from it – keep this principle in mind to invest wisely.
In Summary: Choose Wisely According to Your Need
Choosing the right refresh rate for your business screen is a significant part of getting full value from the investment. Here are a few final guidelines:
- Static or slow content (office, information, menus): 60Hz is absolutely enough. Focus on panel quality and comfort features (such as anti-glare coating), and not on chasing high Hz that won’t contribute. Make sure the screen is stable and flicker-free in lighting at any brightness level – for eye health.
- Dynamic and marketing content (stores, shop windows): Consider 120Hz if the content is fast and your goal is to impress with smooth motion. This is a visual “bonus” that customers may subconsciously rate as a higher-quality viewing experience. If the budget is limited, 60Hz will still do a good job – but try to leverage techniques in content production (for example, avoid fast 24FPS pan motion that may appear stuttering on 60Hz). In LED displays for stores, prefer 3840Hz internal if you can – to prevent flicker in filming and in different lighting scenarios.
- Large LED screens, events, and studios: Here do not compromise on High Refresh. Require at least 1920Hz, but in practice aim for 3840Hz to be confident in a clean result. Take into account the customer/project requirements: for standard live broadcast, 3840Hz is enough; for cinema and XR productions – inform the vendor that you need 7680Hz. The investment will repay itself in image quality without glitches and in viewer satisfaction.
In summary, match the rate to the purpose: a standard 60Hz rate provides a stable and smooth display in most basic business applications; 120Hz provides a tangible upgrade when you want to run faster and more fluid content (but it’s a luxury when there is no matching content); and high internal rates (1920Hz+) are essential in LED screens to ensure that there is no flicker or strobing, especially when public attention or the camera is directed at the screen. This way you can choose a screen wisely – both technically and economically – and ensure that your display fulfills its purpose in the best way for your business.
The day will come when perhaps all screens will have very high rates by default, but until then, understanding when to keep it simple and when to invest in the advanced is a competitive advantage for you. Good luck with the right choice!
