Has anyone encountered this problem: It's a mac mini. It's connected to a tv via a HDMI cable, both of which work fine with other computers. However, when connected to the HISENSE tv, at native resolution, all black pixels come out as purple. If I switch to scaled resolutions, the colour is fine - but of course the resolution is now off. Any ideas? Thanks


This sounds like a problem I once saw on a DVD player with a DVI output, where it was outputting YCbCr instead of RGB. If there is a video format menu on either device, have a look there

  • Unfortunately, I don't see any such setting on my tv or mac mini. – Ian Apr 15 '14 at 2:33
