Received mine today, I didn't realise how big a 30" screen actually is. Its going to take me a few hours to get used to the smaller screen. No regrets, 4K videos on Youtube look stunning. I might have an advantage in multiplayer games with the smaller screen.
It's not big, most others are just small...
Especially 16:9 low screens.
Myself using same Dell and just can't seem to find anything to replace it with, which would have modern high refresh rate and at least as big resolution.
2560x1440 is out of question simply because of beign downgrade in space in the more important direction: vertical.
3840x2160 selection again has horribly slow advance.
Also advance of connections needed for high refresh rates is equally slow with current models needing either DSC, or scrappy chroma subsampling (analog era fossil like interleaving) no good for PC use.
(and would have wanted actually proper flat display with real contrast instead of another compromised LCD)
