Simply put, I needed to downgrade from a 42" to a 32" (alas no 38" flat screen monior option.) , as I found 42" just a little too big for me when working..
I was a tad wary on the glossy screen of the UCDM but am glad I gave it a go, as it does have a superior display to that of the WOLED model in my opinion in almost every way. (I work in a daylight lit room and no lights behind me so I do not have any reflection issues, I also have true black showing.
I also have not suffered from VRR flicker yet, but thats likely because I am using a 4090 and normally set games to 120hz locked for any game that has a lot of FPS spikes (main cause of VRR flicker.
All in all one of the best monitors on the market, and I am happy with my purchase.
