i can understand, i remember the older laptops where moving the mouse
would leave a trail across the screen. and i've seen newer laptops
have problems with DVD/full-motion playback. (the high-end compaq
laptop, Msomething or another with 15" LCD is the one i've seen, and
it's not even that old - 2 years ago when i saw it).

ah sorry - i thought you were reffering to LCDs! indeed, available
CRTs can do much better resolution. (simply cause it's known and
cheap technology).

my point is an LCD doesnt flicker at all. :)

another advantage of LCDs: lines are straight. no pincushioning, 
etc.. no devation at the edge of the screen.

CRTs suffer terribly from this, esp as you increase the resolution 
and refresh rate.

Also, with CRTs you're sitting in front of an electron gun. i wonder 
how good that is.. (??).

anyway, my reccomendation is if you want an LCD, go to ebay and buy
an SGI 1600SW (make sure it comes with a multilink adapter!!), 'bout
$800 currently. Wide screen, 1600x1024, (can do 1280x1024 native
too), designed for video-editing market so latency was important and
it'll display motion at PAL and NTSC refresh rates without any
ghosting or latency issues.

I've also played a few OpenGL demos/games on it and havnt noticed any
latency issues whatsoever. (apart from graphics/cpu processing power
related latency - ie low fps, 10 to 15ish - on some complicated
simulation demos).

But I definitely agree that general consumer LCDs arent that good for 
playing video or games on - least not the ones i've seen. (but i 
havnt seen any of the current generation LCDs).
