The 48" CX is a TV. It happens to work pretty nicely as a monitor if you have enough space (between you and the display). But in a desktop setting where you are sitting 2 feet from the monitor, you'd have to physically move your head to see all the content. OLED on the desktop means 24", 27", 32" OLED displays.
Yep, completely agreed on the sizes + viewing distance. I've been on the fence but I'll retrain myself from buying it. It seems it has quite a few downsides.
