I'm not sure what that means. No patterns have any color? Most of the early patterns on the disc are monochrome white, but the Chroma Zone Plate, Chroma Bursts, and Clipping all use color, among others.
I have the Sony 1080i 34XBR970 CRT. This TV has always looked dark as though looking thru a medium Neutral Density camera filter.
The first thing is to set brightness and contrast. Start with the PLUGE Low pattern and set brightness, then use the Contrast pattern to set contrast.
Your white patterns are just white no adjustment seems to work.
Can you elaborate on that? Which adjustments are you trying? It's possible that the Sony locks out some controls when you connect via HDMI. If so, then it's unlikely you'd need to adjust those controls anyway. There's no real need for a color or tint control over an HDMI connection. They should just be correct out of the gate. And if they're not correct, it's going to require some fiddling in the service menu to correct it.
The brightness control works but my other TV adjustment is Picture not Contrast, I assume they are the same?
Yes, on some displays they have a "picture" control that is essentially contrast.
Black Crush always come to mind when I turn this set on. PS I have tried all the user controls. Do I need a professional calibrator?
With a CRT set, there is a lot of room for a calibrator to do useful things. Whether you need
a pro calibration is really a personal choice. You should be able to get a reasonably acceptable picture using the user controls, just by setting brightness, contrast (picture), color, tint, and sharpness using the disc. Beyond that, a calibrator can do more, like adjusting:
- Focus for all three colors
- Color temperature
- Gain and bias to improve gray tracking
I can't guarantee that a calibration will make a massive difference; your TV may already be in decent shape. The last CRT I owned was pretty good out of the gate, but after an ISF calibration it was amazing. But that was a Toshiba rear projection, and it had lots of room for improvement from the factory settings.
You should also run through the output options on the Oppo, most notably 4:2:2, 4:4:4, and RGB - Video levels. See if one of them gives you a better picture, or better control, than the others.
