I have the Alienware 38" Ultrawide. The ratios are just slightly off for my eyes comfort. At a full 1:1 pixel ratio, the text is too small. Scaled up slightly the size is right, but the blur is really annoying. I think it would be prefect for me if it were like 45" with the same resolution, or if it were still 38" but instead of being 3840, native it was 3200 or something like that.

If I scale it to 50%, it looks phenomenal, but who wants to work on a screen with the equivalent real estate of 1920x720?

I now spend most of my time on the built in display of my 16" M1 MBP. The text sizing is fine for me.
