I used to own a MacBook Pro Core 2 Duo 15" with a very grainy matte display. I posted a thread about it here: http://forums.macrumors.com/showthread.php?t=251352 Anyways, I returned it because I couldn't stand to look at it anymore and now I'm considering getting a Mac Pro with a 20" ACD along with it. I looked at the 20" at the Apple Store where I was returning my MacBook Pro and I noticed a little bit of the sparkles or grain or whatever you call it but, it was not as bad as my MacBook Pro... but yet it was also not as clear as the iMac display. The screens I was looking at had a lot of fingerprints/dirt/scratches on it so that may have been the reason for seeing this effect on it. Can anyone who owns a 20" ACD confirm whether their screen is really smooth and clear (if they keep it clean) or if it's more like I'm describing in the MacBook Pro thread. Any helpful descriptions or observations about the quality of the display, please let me know. I don't wanna spend that kind of money on a display that's too sparkly looking. As a test... try opening a blank Safari page and move it around on the screen... do you see a static pattern that does not move. Then note whether this is hardly noticeable or very noticeable to you. Thanks.
