I always notice the "stairs" effect, in a game for example if I throw a smoke grenade, the smoke isn't smooth and I can see the differences between shades of gray. Here's what I mean: http://imageshack.us/f/854/smoked.png/ (sorry for my terrible Paint skills). I tried setting the monitor to 16bit, and noticed that it does get worse in 16bit but 32bit looks almost half as bad as 16bit. I only use 1920x1080 (my monitor's native resolution) for games and windows. First time I really noticed this problem was in Skyrim, where the smoke in the menu looked really fucked up: http://media.photobucket.com/image/skyrim%20menu%20smok...(not my screenshot but that's EXACTLY how it looks on my computer too.), is this a normal issue in LCD monitors? I have Samsung EX2220X (http://www.newegg.com/Product/Product.aspx?Item=N82E168...) and Asus GTS450. I have latest drivers for both. What could be the problem?
Edit: I forgot to mention that I have a digital cable not an analog cable for the monitor.
Also my card seems to be working fine, in fact it actually works better than other people's gts450. I can overclock to 985mhz and can run latest games at highest settings except AA.
