I was wondering if anyone can explain why all of a sudden on 12.04 when I plug the HDMI in the text on my laptops monitor gets blurry. When I unplug the HDMI everything goes perfect again, text is crisp, plugin the HDMI text goes blurry.

  • The TV is actually 1080p@60 not @75 and definably not preferred @30.
  • Both are set to 60hz.
  • The proprietary driver is installed and says it's working alright to me.
