I would consider the temperature of a CRT tube as very cool (isolating vacuum), compared to a LCD screen with backlight, so I'm really astonished that even with a CRT there is such a long lasting drift.
A CRT gets warm due to the energy of the electrons hitting the phosphor. (It's noticeably warm to the touch.)
The smaller temperature difference (room temperature<->CRT) should result in a lower drift, so this does not signify that your ColorMunki is better/less prone to drift, right?Recalibrating does not seem to affect this.This means that your ColorMunki is also not back to its first readings after a self-calibration?
I'm not sure what you mean. Recalibration didn't affect the measurements after it had all stabilized.
This reminds me of the question, if it is possible that the temporal dithering used in panels to gain 10 Bit resolution is jointly responsible for measurement variance?
It's a possibility. Instruments like the DTP94 had special circuits to synchronize their readings with the CRT refresh. Recent instruments have dropped this level of sophistication on the assumption that LCD displays don't flicker. Maybe that's not a perfect assumption. Graeme Gill.
