So I found a way to game at 64 k resution but I am not sure if this works.
So the way to do this is to first get 8 8k displays(the same one) and put it together so It will look like one huge display, so after that use a pc with two rtx quadro rtx 5000 sli and use each rtx quadro 5000 for 4 monitors because that is maximum limit.
So finally you will be connecting two rtx quadro rtx 5000 to 8 8k display's so now the last and most important thing to do now is to combine all this display's so now you can go to nvdia control panel and use nvdia's mosaic technology to use the 8 8k display's as a single monitor.(note-instead of nvdia quadro rtx 5000 and mosaic you can use rtx 3090 sli with nvdia surround if it works)
