I usually just use 1280x960 on my 19' CRT, I also have a lcd that can do 1280x1024 but after playing on it for a long time then switching back to my crt it seems like my crt tears alot less and isn't stuck at 60hhz, I get 85hz at 1280x960 and 75Hz at 16x12.
Well, I use my 22" CRT most of the time. 1600x1200 is the most common resolution I run, but it can be anything from 1280x1024 to 2048x1536 depending on the game. I don't find 30-40FPS playable, so I tend to use lower resolutions than you might expect from an X1900XT.
im on a 2005 (due to the fact that a CRT would not be practical for me)
so my native res is 1680x1050, I obey the native res (stupid battlefield 2 and fear dont have my res though, but im patching both to see if it updated)
but i dont play BF2 for the sake that I cant stand it, and I dont really play Fear too much either
I'm using a 16ms Hitachi CML174SWXB 17" LCD @ 1280 x 1024. My refresh is at 60hz and I rarely game with V-Sync on.
I'm planning on getting a 20.1" widescreen LCD in late March (that's if any relatives send $$$ my way for my B-day). I rarely watch DVD's on my computer and I doubt I'll need to worry about watching protected HD content on it anyway - I have my 26" Toshiba for that.
So when I get the new screen, I'll be using 1680 x 1050 and I can't wait!
