    Graphic problems (see image)
    Does anyone have any idea what I get this image in my Mac Pro 4.1 + ATI 48xx graphic card?

    It happens every 1 of 3 times I boot up in windows.
    If I can enter my session and close the session I get the image correct next time in the session's login screen.


    Thankyou
    Gus

    Are they using the same resolution? Without knowing what you're using for running windows, it is hard to just guess. There could also be a hardware fault, but that would take more testing and I dont see that as being what is wrong, provided you are having no issues in OSX.

    Specs:

    BOOT CAMP 3.2
    WINDOWS 7 64 BITS
    ATI RADEON HD 4800 SERIES
    AMD RADEON CATALYST CONTROL CENTER 2011.0524.2352.41027

    Never had any issue under Mac OS X.

    Are they using the same resolution?
    It's not related to resolution, I can login (with luck if I can put my cursor on my login icon) and I got the same distorted image.

    Thankyou

    For my ATI Radeon HD4870 had to download the drivers from Radeon's site and install otherwise resolution was all over the place. Have you done this as yet?

    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    I installed the last
    Catalyst Software Suite 86.4 MB 11.6 6/15/2011
    drivers.

    I got the same problem, first with apple bootcamp drivers and now with AMD "official" drivers.

    But "the problem" is that only happens 1 of everery 3 o 4 times I boot with windows/bootcamp.

    Download the correct driver and try that. You will need to be in Windows to do that, and install.
