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...)…

Some may argue as well that you can obtain better contrast in LCD but I'm no expert in that matter - I have just learned why CRTs are bad due to working as a programmer.
