Speaking of CRTs, I hooked up my old CRT recently and while the resolution wasn't great, there was a warmth and depth to the image that an LCD just can't replicate. 3d games felt a lot more immersive.
One day I will own the legendary Sony FW900...
The warmth you're explaining is called radiation.
CRTs are the standard that other technologies are measured against. Those RGB phosphors were good and distinct. The short image interval (lots of black between frames) helps immensely to avoid motion blur. They have gaming LCDs that strobe the backlight to restore the clarity of moving objects.
It's mostly pixel shape. CRTs were pretty much a screen level anti aliasing. That's why some games you remember looking nice in 1024x768 are unbearable on LCD.
