So I have ATI Radeon HD5450 video card, And Samsung SyncMaster 920nw, Yesterday, I mistakenly clicked the Auto button, The screen is now.. a bit down, You only see half of the taskbar only, Also, There is an annoying black bar in the top of the screen, I am using 1440 x 900 and it is highly unpleasing to use less than that, Thanks in advance for support.. I obviously tried resetting settings.. etc.. etc..
