I am using in a still under construction pc a CRT screen.
Two things became obvious:
1. CRT contrast is amazing, specially black levels. DOOM 4 is utterly gorgeous.
2. Yet CRT is now mostly unusable because questionable design decisions, I keep stumbling in new games and websites that presume you have a 4k monitor (seriously, I saw some games where the UI on my screen ended with letters unreadable without a loupe...) and presume you have a specific type of lcd, and thus rely heavily on subpixel anti alias that beside obvious looking outright broken on crt with deformed letters, also look wrong on panels that aren't classic lcd or have a unusual pixel organization (for example a panel that instead of rgb in horizontal is gbr, or vertical, or a triangle, or those cheap mobile panels with less blue pixels)
One of the things that most piss me off are windows new default font, that was designed to only look good on lcd. And all those custom web fonts, sometimes gigantic, so you see for example a newspaper article load with all images, then suddenly the text disappear and only come back 2 minutes later and with some funky unreadable font.
