Dell U4323QE Reviews

Not ultra sharp

By Craig
Rated 3 out of 5
Date: 2025-05-22

This display is very big. But it's pixels per inch is just 106, which means the that overall, performance is much worse than a 4k 27 inch monitor. It's just blurry, especially text, and not crisp. I love the connections, which act as an excellent docking station for my MacBook. Not sure if I'll keep. I like the size, which makes it easy to view vertical documents, and the ports. Screen resolution is a several steps down from my iMacs and MacBook.

Great Photo Editing Monitor

I eliminated multiple monitors by going to this one. Great color. Great resolution. I would buy again.
