Well i replaced it with a 1280x1024 19" tft some years ago, but later i got a 1680x1050 22" tft (sold already) and a 1920x1200 25.5" tft. When you are used to full hd or higher res you definitely never want to use a CRT again.
In theory you would not need 24 hz but 24000/1001. But i never used that to watch a movie and i am still happy
I will add to the calls for a return of the refresh rate option, since with KMS the default frame rate in games is locked to your refresh rate, and I know it does not really matter when it is over 60, but I would rather it be locked to 75.
Of course I could always just use lxrandr instead (or just plain old xrandr). But I would prefer to have the setting back.
