Some are. The larger iMac screens, eg 24 and up, are IPS displays which
don't exhibit the banding. The older iMacs and all the Mac notebooks

Which is good news, undoubtetly. But I'd be surprises if the gamut of
mac screens is anything to write about. Note I myself have a mac so

Tim, what happens if you save this picture as an uncompressed TIFF file?
Methinks that if you will still get issues - the problem is not in
