While the world cheers on 4K, and some manufacturers have even introduced 8K displays, a little detail slipped through HDMI’s official 2.1 spec sheet: It’ll support 10K at 120Hz. The problem is driving that many pixels. Current GPUs can usually maintain 4K at 60fps in current games, perhaps with a few tweaks to the settings. 5K is 78 percent more pixels than 4K, and 10K is four times as many as 5K. Then double the requirements again to hit 120fps. That would be over 14 times as many pixels as 4K, or 55 times as many as 1080p. If we assume an increase in GPU performance of 30 percent per year, it will take 10 years before GPUs can handle 10K panels at 120fps in games. Your grandkids will love it.
