did you recently update any drivers? if so, maybe try rolling back to the previous version - its odd for this to suddenly start happening on its own.
There is, but I can't manually adjust it.Drivers don't have any effect on the BIOS since you get the BIOS before your OS begins to load. See if there is an 'auto-adjust' option on your monitor.
