when i wanted to log in SL today, it didn't wanted to put me in full-screen mode...why?
i'm always full-screen 1280x1024 usually, and now it says "failed to switch resolution to 1280 by 1024.
why does it happen?
the only thing that i changed is the refresh rate on my LCD monitor (75Hz instead of 60Hz)

LCD monitors do NOT need higher than 60hz, in fact you can damage them! Changing the refresh rate is only for the big, TV type CRT monitors. This is your problem, change it back.

so i wonder why some peoples run their LCDs at 75Hz. and don't get me wrong, those who are doing this are not newbies in computers.
i noticed when you're in 75Hz, you get a higher framerate.
i wanted to switch to 75Hz because i get tearing while playing games.
i think tearing can be done by 2 things:
1- framerate going higher than your refresh rate
2- response time of the LCD monitor
i have a 8ms LCD monitor (Samsung Syncmaster 730b)
my monitor specs says it support 60Hz to 75Hz.

Ok, after reading up on newer LCDs (my info is a couple of years out of date) I have to add some caveats to my previous post. The most important thing you have to do when setting refresh rates (there actually is no such thing as a refresh rate on an LCD since it doesn't have phosphors that need "refreshing" from the electron gun) is set the LCD monitor to the refresh rate the documentation that came with your monitor says to. Some models have an "interpolation" circuit that takes a high refresh rate and interpolates it so it can be used by the LCD to reduce tearing in high movement video. Other monitors have a high refresh rate as its native refresh rate and it needs to be set to that number. Older LCD monitors (like mine) can be damaged if set higher than 60hz, my 38 inch Westinghouse will simply shut down if I try.
Bottom line, if you are having video problems, put everything back to its native resolution and refresh rate specified by the manufacturer. Just because you are given a list of refresh rates it can display doesn't mean you are free to use them without consequences. Many a CRT has died because the video card said it could display at 120hz, it just didn't say it would only do it for 3 or 4 days before the CRT became unusable.
