as far as I am concerned no problems encountered to date works both on HDMI and thru DVI. All works as it should for me not as reported by many. My configation Late 2012 Mac mini i7 2.3 16meg Osx 10.8.3 all fixes applied. Apple Cinema 20 inch.... with DVI connections - Panasonic Viera LCD two years old (not the cheap model) Ran a test as we are late in watching a TV show and wanted to see it on a larger screen. all was fine through HDMI directly. Colors good. But decided to Color manage screen so I could see what the image from my real work would look like. Profile app DATACOLOR Spyder Pro Scary. results sRGB Gamut Panasonic 99% Cinema 98% AdobeRGB Gamut Panasonic 77% Cinema 77%. I was shocked to see the similarities in the final result of the charts. I reran to see if I made an error? none that I could find. This is after reading all the horror stories about crushed whites, etc etc.. Only answer I have is the better quality Panasonic that I bought twice the price of cheaper models. cheers elo This thread was move over to another forum by the moderator. I understand why. But as so many had complained I felt it should be covered in this forum and maybe it will help others to see what may have gone wrong with their HDMI connection.
