Depending on your choice of games or game genera, you probably chose your monitor for its fast refresh or for its huge number of pixels. Competitive gamers tend to favor high refresh rates where every millisecond counts which hug the lower end of the resolution scale. If you like slower paced games with cinematic fantasy or dystopian landscapes, you probably want to see every jaw-dropping pixel in 4K UHD, but you won’t be getting more than 60 frames per second out of your monitor. And that’s IF you have a system with enough graphical muscle to even handle 4K resolution anyway. A lot of gamer’s compromise, a higher resolution like 2560x1440 or maybe an ultra-wide 3440x1440 and a refresh rate in the 100-120Hz range which provides a good middle of the ground approach.
