Honestly, the graphics quality is the reason I have 3 4K displays. I run them at 2x scaling and they are not fatiguing to use. 5K would be better though, as 1080 pixels wide feels a little tight on some websites. A single 8K display would probably be better, but well-reviewed and reasonably priced 8K monitors are not really there yet.
