I am having some problems opening any photo format in Photoshop CS4. They all look like the linked picture at 100% or less. If I zoom in to 200% the photo looks fine. I have tried uninstalling and reinstalling Photoshop. And I know the question will come up, Yes I can open these files in any other software, including Bridge, Lightroom, Windows Live Photo gallery, etc, etc. This photo is just a screen shot of what it looks like for me at anything 100% or less. Thanks in advance for any help.

Have you considered reinstalling/updating the video driver?

Turn off OpenGL acceleration, or update your video card driver.

Turning OpenGL off fixed the problem. I had turned OpenGL off awhile back for some other issue and apparently when I updated my drivers a week or so ago it must have reverted back to OpenGL on. The question is what does OpenGL have to do with an error like this in Photoshop? Thanks for the help btw Chris.

With OpenGL drawing on, OpenGL is used to draw the image. If your video driver has a problem (bug), then the image may not draw correctly – as you saw.

So, until you get a driver that fixes the bugs, you can leave OpenGL drawing turned off to avoid running into the driver bug.
