Ight, here comes a 5 page essay
With regards to moving objects- yes, LCD's are worse than CRT's. How much worse depends on how much u personally notice it. Eventually u get used to it. In addition, a new line of lcd's is coming out of every company that has a 16ms response time, in which there really is no ghosting (or almost not noticeable) so that would be fine for gaming. The real issue then would be with grey tones (anything not 100% black or white) but that will be remedied soon by FFD (like within the next few months LCD's w/ it will come out). Currently, gettting the best LCD in terms of response time will be good for gaming, not the best compared to CRT, but certainly good 'nough. Wait alil more, and u get something perfect for gaming.
Viewing angle- this is a measurement of at what point the screen is at 1/10 its contrast. LCD's piss me off in that sense since u move a little and the image looks off. This is better though w/ 170º viewing angle found in many lcd's now and 160º will suffice. Note though that it still won't look perfect from the side. Once again u get used to it.
Contrast- lcd's now have up to 600:1 contrast generally, which is good. However, w/ moving images the colors won't be as vibrant cause the screen can't respond fast enough to make them look their best. Colors are a lot brighter though now w/ the 16ms response time lcd's.
Brightness- Christ LCD's are bright. 250CD/M^2 or more- real bright. You'll need to turn that down to like 20% hehe. That's one area which is annoying since w/o very high brightness high contrast can';t be achieved as easily. Then again, u won't want high contrast when using word for example either. For games (especially dark ones) turn it up, but not to its fullest.
Sharpness- imo, LCD's are sharper than CRT, that is if running at native resolution. If not it doesn't look as good.
Overall in terms of eyestrain it depends on teh person, but usually LCD's cause less eyestrain b/c they don't refresh, are prefectly flat, and generally are sharper than CRT. This bs about radiation and stuff is untrue, CRT's don't emit much so there isn;t a real difference there. However, too high contrast and brightness on LCD will cause a lot of eyestrain, so make sure to fine tune those.
Overall, given the right LCD (I guess now the Hitachi CML174 would be good, or in december 27 the Planar PX171M, though we'll have to see how that one performs) you could very well use it for a gaming system. The option is up to you. Personally I intend on getting a 19-24" LCD within the next 4 months, just waiting for 16ms response or less w/ FFD and 170º viewing angle and something not too bright.
