My computer screen is too dark. The buttons to increase/decrease brightness on monitor seem to have died. When i play movies this is very annoying. With some movies, i generally get .avi, you can adjust brightness in Windows Media Player. Others the player does not allow it. Does this have something to do with the file encoding? Is there an alternative video player where brightness can always be re-adjusted Btw I have an onboard video card, cannot change advanced brightness settings in display.
