Native resolution is gone all of the sudden

[sheetrok]

hey guys 1st of all thnx for reading my thread. all of the sudden my monitor wont go to the native res of 1680x1050.
most commonly i see this was happening to people who updated windows which i didnt do i have it set to never download or install updates.
i have windows 7 currently and everything was fine for a year or so until today. i have an ATI 4850 which i updated the drivers after i saw my native res was gone and it didnt change anything.
every night i hook up my pc to my tv thru the extra dvi slot to watch netflix but ive been doing this for months and never had a problem.
not sure what else to try ive been searching the net all morning and cant find a fix plz help me TY

It might be the monitor failing. However, one thing you can try is to use a different cable connection and see if that helps. For example, if you connect with DVI try VGA.
