Afyer I intalled "new" 15GP22 in my CT-100 I took many pictures. They should, at least
in color over large areas, look just like any other 15GP22 set. I apparently never posted them so I will here. They do look much like yours. On my
calibrated monitor they look almost identicasl to the TV itself, as currently
set up.

"Currently set up" implies with the color level set using both "blue bars" from
calibration DVDs an also all three of blue, red, and green bars from my own
pngs played on my Blu-ray player from a USB key. These generate similar but
not identical settings for the color control; I'm using the average. The hue control does not differ between the two.

I've tried numerous different file formats and color gamut settings. These are
Adobe RGB, but any wide gamut looks essentially the same.

These are photographed with a Canon 7D using manual exposure and white
balance.

They are made with a 50mm lens which is defocused a bit to blur the triads
just enough to make them overlap. In Photoshop they are further blurred
using "box" blurring, then converted from 16 to 8 bits and cropped to be 900
pixels wide. No detail visible on the screen is lost, including convergence
errors. There is a very mild amount of purity problem, essentially invisible on
these highly saturated scenes. The biggest color error by far is that the blue bar on the color bars is too bright.

Some of these pictures are at very close places in the Wizard of OZ as the ones of the Westy. I include dark scenes to show the low light performance. It really looks like that. I think the pictures are too saturated, but that's what the calibration says is right.
