Still better than 640x480
What's why I replaced my 4K monitor for a 1440p... Barely anything supports 4K
Fullscreen it and play lower resolution, I use 1440p monitor and play with 1650x1080 ingame, just make sure u have it scale by aspect ratio in nvidia/amd control panel
Why would to trade in something better for something worse? Just play on lower res.
1440p 144Hz > 4k 60hz
But he only has a 60 hz screen.
