You read that right 10K, while the world of entertainment and PC gaming attempts to get up to scratch with 4k(3840x2160) resolution the newest figures form the official HDMI 2.1 spec sheet claims it will support up to a whopping 10K resolution at a very respectable 120Hz refresh rate.
The problem is that at 10K you have about 55 times as many pixels than 1080p (what I would say is the most common gaming resolution), and more than 14 times as many as 4k. How do you get a GPU to power that, the answer is you don't not for a very long time. Right now the best gaming GPU you can get is a GTX 1080ti and even overclocked it can just about maintaining getting 60 FPS @ 4K in current games never mind getting over 120fps @ 10K.
If GPUs steadily increase in performance by say 30% per year you are still talking 10 years or so before we have close to the performance needed to dive that many pixels. Maybe the other entertainment sectors like TV and Film will take on the challenge before games do, right now I would be happy at focusing on getting high refresh rate 4k displays and the GPUs to drive them. A solid 27" 144/240Hz 4K monitor would be a very nice thing indeed.
Speaking on monitors, there is already one that comes close to running such a high resolution and that is the Dell UltraSharp UP3218K. A very tasty 32" 8K Monitor released earlier this year, all them pixels don't come in cheap and it retails at around $5000 and is very much aimed at graphics professionals, not gaming and considering the discussed GPU limitations you would have to be very silly or very rich to even attempt to use this as a gaming monitor.
