Second monitor suitable for my iMac 27-inch 5k

[coolerkid]

I'm looking for a second monitor, ideally around 24-inch 4K, to use in vertical orientation with my iMac. I have tried multiple monitors already and they all look ridiculously bad compared to the iMac. Of course I don't expect it to match the 5K screen at all, but none come even close. The whites look almost gray in comparison, the text is not sharp at all and the screen is overall very dim compared to my iMac. The LG Ultrafine would probably be a good option, but it does not support vertical orientation. I had an old Dell monitor which I was using for years that was plenty bright and looked fine next to it, but it died and I can't find anything comparable. I was looking at the Dell U2723QE to try next. It's bigger than I wanted, but can probably handle if the quality is good and there's no 24" comparable monitor.


Any suggestions?

The LG 24" 4K would be your best bet. I believe you can mount in on a VESA monitor arm and then rotate it so you can get it in portrait mode. The Dell U2723QE is also a good option if you want slightly better contrast, a larger screen and the plenty of ports that it comes with.

That was my first choice, but they say you're not supposed to mount it vertically. Apparently the vents were not designed for that. Not sure how true that is of if it'll be an actual issue or not but that's what I heard and what LG claims.
