If we can make 4K resolution phone screen, why can’t we “stack” those smaller screens to make a much higher resolution tv screen?
In: Technology
There are a few things to consider here:
1) You need to find a way to make sure each screen gets its part of the image, and updates / refreshes at exactly the same rate, perfectly in sync with all the other screens. Otherwise it won’t function like a single large display.
2) You need to create a video output device that can physically connect to this many screens in the first place. These do exist, for sure, but they’re not exactly common.
3) You need to have the graphics processing power to actually… do things on such a high resolution display. It’s one thing to show a home screen or desktop wallpaper, and another completely to play native-resolution video, interact with software in a smooth and responsive way, and play video games. All of this gets harder the higher the resolution.
4) Even if you solve the other problems, the result will be ludicrously expensive and probably won’t look any better than an 8K TV. There does come a point where more resolution doesn’t give you any more visible detail so long as the distance to the observer is reasonable.
