Even if you were able to use your X-Rite colorimeter to profile the display through your computer, it would only be valid when using your TV as a computer monitor as the calibration information is stored and used by the computer, not the TV.
Yes, of course. Understood! However, my plasma display has a whole range of contrast, brightness and color settings which are specific to each input
. If I were to use the display for color critical work, as a computer monitor, whatever adjustments I were to make to the set's contrast and brightness before calibration, would not affect the other inputs. The set would continue to function as a TV for all TV broadcasts, or DVD movies from a stand-alone DVD player, which is fine.
Normal broadcast material varies in image quality and color accuracy much more (very much more) than any of my
images processed on a calibrated monitor. I don't need the set claibrated for TV viewing. There are so many global adjustments which can take care of source material quality variation, such as 'cinema mode', color temperature warm or cool etc etc.
The intriguing aspect of this is the amazing specs of this 11th generation Panasonic plasma display.
