Task: Question Answering
Input (English): Again , I manually adjusted the settings , but after re - start second monitor would be off . I Re - installed the drivers ( 8.9 ) and CCC but still could not get it to keep the settings after re - boot . After hours of trials and frustrations I figured out that ATI will keep my dual monitor settings ONLY if the resolution on my primary monitor ( Acer ) is set to 1440 X 900 or below . But I know that the card is capable of running both monitors at their native resolutions because I can go into CCC and manually stet the proper resolutions - it works ... It just doesn't keep those settings after re - start . 
Question: Why did I re - install drivers ?
Output (English): Because some hardware wasn't working properly .
