LFS works in Widescreen (1680x1050x32) mode perfectly
Wolfenstein 3D: Enemy Territory has pretty awful flickering in widescreen resolutions in some maps. They go away when I switch to 1024x768 or 1280x1024.
Sometimes while browsing the Interwebs, the screen goes black just like it would go to in "the blank screensaver" for a second or two. (I haven't reinstalled Windows in 18 Months. But still., I'm not a computer-dimwit, that's the only prob in my computer ATM. I just haven't found the cause of it yet...) Somehow I think it's related to Macromedia Flash.
I've also brielfly used the Samsung 226BW, it's pretty much the same as 225BW except it has screen tilt feature and the screen bevels are bit more "Vista-looking" (i.e., flashy and shiny). Other than that, it seems to be the same as the 225BW. Frankly speaking, if you have the cash... get the 226BW
