Many of us Favorite TV And monitors today boast displays with high refresh rates that promise onscreen action and a sharper image. Recent IPhone 13 Pro model 120-Hz can reach refresh rates, such as several phones running Google’s Android operating system.
High refresh rates are also talked about a lot in gaming, where quick responses and instant onscreen updates can tell the difference between victory and failure.
What is the refresh rate?
All content on your display is made up of unique static frames (photos) that are displayed in sequence at extremely high speeds. The refresh rate is measured in hertz (Hz) and indicates how often the frame can change. A refresh rate of 120 Hz allows a new frame to display up to 120 times per second. A 60-Hz display can only refresh the screen 60 times per second. And you can estimate how many times the 90-Hz screen can refresh.
And what about the frame rate?
It is important to note that the potential benefit of a higher screen refresh rate is limited by the frame rate of what is on-screen. With video or video game graphics, it is expressed as frames per second (fps). Movies typically run at 24 frames per second because this is a theatrical standard, while many games can run up to 120 fps.
Touch response rate?
Just to confuse you further, manufacturers sometimes list touch response rates (or touch sample rates) for touchscreen displays, which are also measured in Hertz. This number is related to how many times the touchscreen is scanned for the touch of your finger. The higher the touch response rate, the faster it responds to your touch.
How the refresh rate affects your phone
A higher refresh rate allows a phone’s display to adapt to gaming action and reduce motion blur in video, but it may make navigating around the interface more responsive than a lower refresh rate display. Games look less glamorous during crazy action, video footage of fast-paced sports action appears smoother, and any jolts scrolled over long web pages are reduced. To take full advantage of a high refresh rate, you also need a high frame rate, and ideally, two matches.
Cost often your battery life. You need to get more battery to refresh the picture on the display more times per second. Processing power is also required to run graphics at higher frame rates. Processors have greatly improved, but battery life is still limited to smartphones. For that reason, most phones with high refresh rates do not always run at the highest rate. This includes some The new iPhone Pro 13 model, Which has an “adaptive” 120-Hz refresh rate, which scales at specific times, when you are more likely to notice a difference.
What about TVs and monitors?
The benefits of high refresh rates for TVs or monitors are the same as for smartphones. The onscreen action should be smooth, and the image can be more intense. Here, too, the frame rate of the content is important. There are times when the frame rate does not match the refresh rate, and this can make TV shows and movies worse.
The ‘soap opera effect’ has been explained
Some TVs and monitors are better than others at dealing with the difference between frame rate and refresh rate. Many reduce their refresh rate to match the frame rate, but displays with a fixed refresh rate need to find other ways to deal with this inconsistency.
When a movie is playing at 24 frames per second, for example, but the refresh rate is high, the TV can add extra frames to fill the gap. This can be relatively easy when the refresh rate is divisible by the frame rate, because the TV can show multiples of the same frame. A 120-hertz refresh rate shows 24-fps content, for example, each frame can display five times. But with -0-Hz refresh rate and 2-fps footage you show an unequal number of frames, which can be a judging, shaky effect for some viewers.
