    Can G4 Quicksilver cause monitor to have weird horizonatal shadows across screen?
    I recently had my 19" Envision monitor start displaying unnatural colors and shadows across the screen, as if it was going bad so I went and bought a new 20" HD widescreen ViewSonic. I unpack it, set it up and Wham! It does the same... I calibrate it using the monitor's built in system and it looks even worse .

    Can the Mac (700 mHz) have something go bad that causes these horizontal stripes or shadows to extend off the screen where ever there is a horizontal line or stripe on a window, photo, design or even lines of type.? Color images look out of whack with too much red on some or too much of something else on another.

    I've been creating graphic designs on Mac for 18 years and never seen this occur.

    I appreciate any help from anyone who might have seen this before...

    If it is not the monitor then it has to be the video card as a WAG.

    Of course the video circuit on the MB may be going as well. Trial and error time. Take the monitor back. I just switched away from my 867 and 22" viewsonic 8 years old and showing burn in lines.

    If you know anyone near you with a Mac, Quicksilver and MDD models both have 4XAGP cards, ask nicely to bring your Mac round and try their video card and see what happens. As chilbear says has to be the card.

    Depends what style of display you are using.

    The ATI Radeon 9000 MAC PRO has ADC/DVI and you should be able to pick up a second habnd one for around $50.00. Try and get the 128MB SDRAM version rather that the 64MB.

    If you plan to update the CPU for Leopard,the maybe the 9600.
