I decided to look carefully again at the color rendition of my CT-100.
It was not as good as I remembered. I could adjust the hue control to get
mid-scale violets/magentas or yellows/oranges right, but not both.
I took the top off with the intent to tweek. But doing the critical
adjustments is impossible without pulling the chassis partly out. Too
little clearance with the CRT. So I said, just do a check on
all my normal test patterns from a USB key on the Blu-Ray and
leave it at that. Success! the problem was not the hue control!
It was "color" ... there is just zero way to set both hue and color
correctly without a proper static color bars pattern and the Digital
Video Essentials color filters or equivalent. Near perfect match
between big TV, computer monitor, and CT-100 on a slide show
(with color temperatures on LCDs set to match CT-100). Back
to OTA and still a great match.
Moral: don't complain about color rendition without setting color bars right.
Ideally you want 75% brightness 100% saturated bars. I have
special tests I made up (and posted) that allow you to use either blue
or red bars (or green ones if you have a proper dichroic filter better than
the plastic ones) but blue alone is OK if the room
is truly dark.
