Anyone getting screen flicker in the top horizontal 1/3 of the screen? Rather irritating. Initially I thought it had something to do with Firefox3 until I noticed it happening while in other apps with Firefox was closed.

..and no I'm not using a KVM.

    That is going to be one of two things, either the Video cable is getting pinched, or it is the LCD itself, just over time they wear down.

    I would suggest sending that in to a repair company or if you still have Applecare they should be able to help you.

    Hope this helps.

    i get a mild flicker on lower brightness levels as if the refresh rate is a little off. Don't notice it though at higher brightness levels.

    I had this same problem (1 horizontal pixel across 1/3 of the screen would flicker) and I returned it and now my new one has white light streaks coming from the bottom. *****.

    I have a new MacBook Pro 15 inch that I bought the first day they were available. I too have noticed screen flicker. It only occurs on the left side of the screen and is only noticeable at somewhat reduced brightness. I'm trying to decide whether to take it back to Apple for repair or replacement, or whether it should be considered within the working parameters of the screen, as it's not apparent at "normal" brightness, i.e., the brightness most people probably use most of the time. Has anyone consulted Apple about this and got a response?

    same thing here. I'm probably going to leave it as it's not that bad and after it's been on a while the flicker goes away. But please let me know what you might do.

    I ordered my MBP the day they were announced. After about three days of use, I get intermittent flickering of the bottom 1/3 of the display that looks like snow on an analog TV not tuned to any station. It doesn't last long - < 1/2 second. I generally use an external display (90%) and haven't noticed it yet on the built in display. Has anyone else noted this behavior? It seems to be occurring with more frequency.

    I just saw a flicker, at around top 1/3 of the screen. Was running on batt, about 30% brightness, and was using FF3.

    what kind of flicker was it though?

    mine is like a slight pulsing, vibrating, very mild though.

    The flickering is like there's a bad connection. A whole swath of the screen becomes snow. It flickers in and out and then just resolves. I've since had the whole screen come up snow and then spontaneously return to normal after about 2 - 3 seconds. It is very annoying. I've also had the computer wake from sleep and refuse to show anything on either monitor when it comes out of sleep and require a reboot. I can hear interaction that indicates the computer is otherwise running the software fine - just not visuals.

    I also noticed that at lowest + 1 brightness level, the screen (the LED I suppose) pulses, I experience this consistently when I go down to the 2nd to lowest (the lowest is a dark screen) level of brightness.

    yes me too, but mine goes away after it's been on several minutes. Doesn't yours go away eventually? Are you gonna take it back?

    I am actually experiencing slight vertical lines on the bottom center of my new MBP screen. They are only visible if the screen is viewed from 20 degrees or more. Straight ahead, you cannot see them. Has anyone else experienced this? Should I take it to apple?
