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.

This is why I've stuck with my pair of older 24" 4k dell monitors.

Before them I was using regular 2k monitors, and would get headaches staring at a monitor for a full workday 8-10 hours and my eyes were so strained I usually ended up just going to bed right afterwards. I've never used an ultrawide, but I'd be really interested in trying one out IF I can get a similar PPI (~192 or higher)

We have multiple, there's a "5k" LG /MSI and a 4k x 2 Dell
