But the fundamental difference is that LCDs are static. Like, if you have a static image on screen, it does not refresh. A CRT is always refreshing at x Hz. On LED backlit displays, it's the cheap PWM brightness controllers that can be noticeable. They're supposed to pulse hundreds of times a second to maintain the brightness setting, but as you go lower, it can be noticeable and tiring on the eyes. On LCDs, refresh rates matter only in constantly changing pictures, like movies and games. On a CRT, you're exposed to the constant refresh flicker even if you're editing a file or reading an article. All in all, I'm happy with LCDs. Even in games, they're enough for me, I'm not that competitive.
