[QUOTE="chscag, post: 938318, member: 46727"] What do you mean "you increased your graphics card through Apple to 512"? The GPU is surface mounted to the main board (logic board) on the iMac and also the notebook line of computers. The graphics chip can not be changed. I think you mean you ordered an iMac with the 512 MB GPU option? In any event, a graphics card is not going to induce smudges on the inside of the glass protective panel or on the display. If the smudges are occurring it's possibly because the display itself is defective. You just got two defective displays - bad luck. Maybe the third will be OK. :) Regards. [/QUOTE]
