    I've got the same setup and I'm experiencing the same issues.

    I have also been experiencing the same issue as you since installing Leopard (a black or mixed colour line) and my configuration is identical as you've reported. I am running dual 23" Apple LCDs and have actually had the line span across the displays at times as well. This is an intermittent issue and I can't narrow it to any application or process, but the original upgrade to 10.5 was the trigger and neither the 10.5.2, nor graphics update resolved this for me.

    Same problem here. Intermittent. Occurred prior to installing Leopard and after.

    Similar problem, certainly more than an issue here.

    I have Leopard 10.5.2 and can't recall seeing black vertical lines running down my screen until 10.5.1.
    The lines are more obvious when I'm looking at and editing images, I can't see too much of them against this background.

    I suppose I'll have to spend the rest of my time looking at Apple Discussions and therefore not worry so much about my thin tiger lines in Leopard.

    We're experiencing the same problem on two power macs in our office. Both running with single 23" cinema displays. We've tried doing and "archive and install" of Leopard, as well as a clean install of Leopard and then a restore from time-machine backup. Still no help. At this point, we're waiting for a slow Friday before starting over from scratch with a fresh install of all applications, etc.

    Any help before then would be greatly appreciated.

    I am experiencing black lines , and blotches of color, usually a shade lighter than the blue background, as well as a wide, irregular vertical yellow line at either end of my display.

    I have four hard drives. As soon as I received Leopard in early February I loaded it onto three of those hard drives, but not the fourth. I did not use any of the Leopard hard drives until after March 16, when I took the flying leap into the abyss and loaded Leopard onto the fourth hard drive.

    It was a point of no return. Until I upgraded the fourth hard drive I had continued to use the latest version of Tiger, without any "weirds" on my display, a Radius Press View 21 SR.

    From that moment on I had, and have a horrible display. I cannot use the display for FCP or for image editing if the work requires color correction. The screen is full of what look like large square and rectangular pixels of a color several shades lighter than my solid blue background.

    As a direct result of this problem last night I bought an HP w2207h display. The same problem appeared on it.

    I erased the contents of one hard drive and reinstalled 10.4.11. that hard drive is a partition of a larger drive.

    The problem persists. This is a problem not of hardware, I believe, but of software. It needs to be addressed by Apple and a solution found.

    I have many, many digital images of the screen and can send them to anyone who will listen or who can help.

    This is not what I expect from Apple, whose computers I have used exclusively since 1987 when I bought my first "luggable" small screen Macintosh Plus.

    This is bad news.

    Still getting random black lines on 30" Cinema Display -- and random patches of color sometimes -- I wish Apple would address this!

    SOLUTION: replaced ATI Radeon X1900 XT graphics card with a new one and now 30 inch Cinema HD display works fine, no black lines or other problems.

    I have the Nvidia 8800GT GPU and am starting to see a 5-6" horizontal black line near the top center of my 23" ACD. Once it started it seems to stay and it seems to be getting slightly wider each day.

    Black lines all over the place increasing as the cpu warms up. I've been seeing this posted all over the net but no consensus on the fix. Apple, anyone?

    I'm getting the same lines, black and going partially across the screen horizontal, on a MBP though, changing colours from millions to thousands and back again fixes this for a couple of hours, also the yellow colour appears as well...

    I have the same problem and nothing seems to fix it.

    Same problem I think. I get vertical black lines on my 30" Cinema Display. They disappear if I close a window-usually. No answer but I thought I would add my experience in the hope that Apple is watching (and motivated).

    After updating to 10.5.3...

    Still the same. APPLE!!!!!!!!!!!
