While the modern world cheers on 4K resolution, and some manufacturers have even introduced 8K displays—like that insane Dell UltraSharp—a little detail slipped through HDMI’s official 2.1 spec sheet: it’ll support 10K resolution at a full 120Hz refresh rate.
Initially introduced in January of your year, HDMI’s huge 48 Gbps bandwidth was heralded to be 8K 120Hz capable, that is certainly more resolution than any current GPU are designed for. We even reported about it here. A peek back along at the spec overview, however, signifies that 10K resolutions are possible at 50Hz, 60Hz, 100Hz and 120Hz.
The issue driving that numerous pixels. Current GPUs such as GTX 1080 Ti, our pick to get the best high-end video card, can usually maintain 4K at 60 fps in current games, perhaps with some tweaks to the settings. 5K is 78 percent more pixels than 4K, and 10K is 4x as many pixels as 5K. Then quantity performance requirements again to strike 120 fps. That will be a lot more than 14 times numerous pixels as 4K, and up than 55 times as numerous pixels as 1080p.
If we assume a somewhat generous rise in GPU performance of Thirty percent each year, it should take about ten years before GPUs are fast enough to address 10K panels at 120 fps in games. Film along with media would be less difficult, but maybe the current HEVC specifications don’t go above 8K at 60 fps.
There’s still the question of the to do with those pixels. A 27-inch 4K display has around 160 DPI, and from a distance of over a couple of feet, many people aren’t equipped with eyes that happen to be good enough to resolve the sufferer pixels. You may have a 10K screen having a 73-inch diagonal and get the identical DPI. Theoretically, 10K would have been a great resolution for truly incredible VR, nevertheless measuring only in case the pixels can be rendered quick enough (minimum 90Hz, possibly a lot higher).
There’s no word on when devices supporting 10K at 120Hz will begin released, but because of the above limitations, don’t expect to upgrade in the near future. On the other hand kids or grandkids will delight in it.
