The screen of the Galaxy Note 20 Ultra is not normal

The Galaxy Note 20 Ultra is one of the most ambitious mobiles that Samsung has presented that we can buy in Spain. This terminal raises the bar in a range designed for professionals that little by little has ended up catching on among enthusiasts looking for the best possible mobile.

Normally this range takes all the good of the Galaxy S presented months but in a larger size, with a pencil and some extra innovations. Yesterday we knew about the strange chip that offers NFC, eSIM and UWB all in one, but it is not the only exotic component that we find in the latest Samsung terminal.

The screen of the Galaxy Note changes its refresh rate continuously

One of the fashionable technologies in the high range is the screens with high refresh rate. This technology consists of increasing the number of images that a screen is capable of displaying per second. By displaying more images in the same order of time, the feeling we perceive is the most fluid, and the cost is a higher battery consumption.

This is a problem? Well, not at first. Whether it is our 90, 120 or 144 hertz screen, if a content must go at a lower refresh rate, we will perceive that the screen’s refresh rate has changed.

For example, a video that is recorded at 30 images per second, you will perceive this level of fluidity, but internally what a 90 hertz screen will do is show each image 3 times, while a 120 image will show 4 times each frame.

Although to our human eyes there is a “change” in the refresh rate, what happens here is a trick to display the adapted content, but the battery still suffers a screen that is refreshed 90, 120 or whatever times.

The screen of the Galaxy Note 20 Ultra has a new technology to avoid this unnecessary battery consumption called Variable refresh rate. This technology adapts the refresh rate dynamically depending on the content we are watching, refreshing itself 10 times per second when we see static content, 30 or 60 times when we see content that has been recorded at that frequency and the very fluid 120 hertz when we see them. required.

There are screens like those of the Pixel 4 that alternate between 60 and 90 hertz, and even customization layers that allow us to choose a specific refresh rate for an application or game, but these changes in the refresh rate are not made continuously , and when they occur we notice a flicker.

The variable refresh rate is not a new technology, since we saw it in equipment like the iPad Pro (technology to which Apple put the surname ProMotion) but with the Galaxy Note 20 Ultra it is the first time we see it on an AMOLED screen .

The fact that there is a theoretical energy saving does not mean that in practice the battery will last much longer.

In theory, this type of screen saves energy in the use of the screen, but determining how much extra autonomy it ends up offering is complicated, but we are sure that it will be a very present type of screen in 2021.
