Question about LG UltraGear 38GL950G-B

I can't judge that because I don't use a PS and mostly play with keyboard and mouse, controllers only exceptionally. With regard to resolution, I don't know whether 4K, 5K or the upcoming up to 8K monitors still make a big difference visually or in perception. Technically, the game developers have to support different monitors first. The advantage of this monitor, however, is its "speed". Up to 144 Hz (overclocking 175 Hz) has hardly ever been seen on other monitors. By the way, too fast for many older games. For example, Fallout 4. I have a 2080Ti with this monitor. Mouse and keyboard already have their difficulties, and the problems have to be "fixed" with tricky settings. The problems include, for example, skipping or overlapping during dialogues or annoying lags with the mouse and keyboard. This also leads to the fact that the frame rate in such games has to be throttled to 100 FPS or even less, probably because the decompression of the game data and/or the rendering is too slow. However, one never finds the exact causes.
