Windows Photo Viewer decreases bit depth, adds dither
I'm not quite sure if this is a video card thing, but it's the best place I could find. I'm having this odd issue on Windows 7 Ultimate 64-bit on my desktop. Any images (JPG, ARW) viewed with it appear downsampled to a lower bit depth, however viewing them in Adobe Bridge or Photoshop is just fine. I have installed Microsoft's RAW codecs, but I doubt those are causing any problems. The same images are just fine when viewed with Windows Photo Viewer on my laptop, which is also running Windows 7 Ultimate, but 32-bit. My monitor bit depth is set correctly.
