Well, I’m coming from an old Dell U3014. It's a 30in display but only 2600 x 1600.
I've had it for years and have gotten used to the productivity benefits of a 30”. When I step down to a non-retina 27" that I used at client office, it seems cramped, so I am worried that the Apple monitor is going to feel too small.
I bought a different (cheap) Dell 32" 4k (S3221QS) and I liked the size of it but it glitched with the M1 and felt like the colors were a bit off so I returned it. I'm hoping that the U3223QE Ultrasharp will do better.
If I open both, then yes - I'll post the comparison.
It's the main reason to upgrade from the Dell U3014 which is still a great monitor despite being about a decade old. The Retina display on the MacBook makes the Dell feel pixelated and blurry. My eyes aren't as sharp as they used to be, so I don't know that 4K vs 5K will make much of a difference to me.
