I've had this CRT since I had Win98 SE, it was very apparent that LCDs were a huge step back. Each year promises of better screens, yet the opposite was true. It was a race to the bottom and there was not one option remotely close to matching the old CRT. Only in the last few years has there been any actual progress on monitors.
Guess I can understand those who have grown up with crap LCD's aren't used to a fairly decent one, same way I grew up with a good CRT and not used to crap LCDs. I've been waiting and wishing and wanting a new monitor for a few years now, for a while I thought OLED was going to be a thing, but it's been at least half a decade now...
It's clear 4:3 will never be a thing again, and I have to accept that everything is going super wide...so if I had to upgrade now I'd probably want to go 21:9 3440x1440 (but not at 34") instead of a 16:9 3840x2160.
My "ideal" version right now would be something around 27". That would maintain roughly the same vertical height of my current screen as well as the same vertical resolution I most commonly use. I'd want a very uniform screen/back-light, since IPS glow seems to be an issue maybe a VA panel. I'd be willing to loose a bit of technical color accuracy in order to have the colors accurately displayed across the whole surface. If I could get a selectable refresh rate (why the hell do we still have "24Hz" content?) from 72Hz to say 90Hz at the top. Needs low input lag and an error free almost zero motion blur. Also, if possible, a 1:1 pixel mapping/output so I can run other aspect ratios without stretching (just black bars). Ideally with a simple menu control to move the image within the black bars (push it up/down or left/right depending on aspect ratio). And since this is a wishlist, have it work properly with both versions of adaptive sync with a bottom rage of say 30Hz. Since we always need some unrealistic goal, put the retail price under $750.
