viirus, you should really check if your monitor CAN display that resolution. The resolution gets set back because either your monitor doesn't support the resolution or you have selected the wrong type of monitor. For the last; Right click on your desktop and click on 'Properties'. Click on the 'Settings' tab and then check what kind of display / monitor it says it has. Check this name with the exact name that is located somewhere on your monitor - especially serial number and such. If this doesn't match (or you have 'Plug and Play Monitor'), go to the site of the manufacturer of your monitor and get the good drivers for your monitor. Let me know the outcome
