Apple is currently in an investigation into the recent 5000 series graphics cards Apple is using on the new mac pro's. Please post here if you have any of the following issues: PLEASE POST YOUR SPECIFIC SETUP AND THE MODEL / MAKE OF YOUR DISPLAYS. If you have photos or videos in action please post! a) flickering horizontal lines in blacks on 30" displays (what make / model?) b) white static noise randomly (looks analogue like bad tv noise) c) display dropout issues - screens randomly go black / into power save mode d) other display anomalies you might have with 5000 series cards (be specific) Please post your specific setup. Again - there is a current investigation happening and this info will help show apple there is indeed a problem. (they currently want to blame all display manufacturers for their LCD panels when there is much evidence pointing to bad graphics cards (5000 series).
