i have a 27" cinema display and noticed with a flashlight what appear to be some scratches or dirt marks underneath the monitor. these are not visible at all without a flashlight and the monitor is perfect otherwise. im not sure how they got there......the only thing ive cleaned the monitor with is a microfiber cloth. is there anything i can do to get rid of them? you wouldnt be able to tell they are there but i want a perfect product especially for the money. do you think i should ring up amazon and ask for a replacement? the only thing im worried is they will send me another one that has something wrong with it.
