[ale] OT: LCD Technology

[Dow Hurst]

Contrast ratio of 400:1 or better
Max display resolution should be noted so you don't get hosed
Screen refresh rate in milliseconds, faster is better
Bad pixel return specs, usually 8 minimum before a return allowed

Those are the really relevent info.  The higher the price the more 
likely it's a decent model.  I've noted that high resolutions aren't 
available til you go way up in price.  I've wanted 19" LCDs at 1600x1200 
w/450:1 contrast but those are way up in price.  NEC makes a 1760NX that 
is 17" with good specs and a thin bezel but you'll pay $450 for sure.  I 
think the max resolution is 1280x1200 too.  CRTs are still way better 
for my particular purposes til the prices drop a lot.  The LCDs I priced 
that fit what I wanted were around $1000 and up.  Usually about $1800 or 
more.  I'll stick with CRTs for now.
