As mentioned in my previous post, the Contrast sections of both ChromaPure and ColorHCFR patterns contains both 0% and 100% full field.

I found it from your advice.

It appears I have to hit the "popup menu" button on my remote to get a drop down menu to select 0 and 100% IRE fields. Found that by trial and error.

Thanks!

See ya. Dave

After some tinkering, I think I have finally got my TV to near perfect calibration from the AVS HD 709 disc. Assuming I am using the A4 color clipping video properly, I managed to get the white balance to near perfect. All other settings have been calibrated as best as they could be from the disc. For a while, I left the white balance at the default "neutral settings", however, in the A4 pattern, red was clipping below 235, and in the white clipping video, the greys took on a reddish tinge at its optimal setting. While the manual says that bars 235-251 are allowed to clip, I found that trying to get green and blue to clip in those ranges was near impossible without some extreme white balance settings. I read in a previous post that some TV manufacturers try to get no clipping in 235-251. Thus, I found it much easier to simply reduce the amount of red offset and gain until there was no clipping from 219-251. I looked up some professional calibration settings for my TV and the settings I am using are roughly the same as the professional settings. Everything looks much "cleaner", and when I revert back the default settings, there is a obvious red tinge. So, if some of you are reluctant to tinker with the white balance, try using the A4 pattern to tweak it to get no clipping from 219-251.

No pro here, but familiar, and not hesitant to ask dumb questions.

For setting up my UHD HDR profile on my projector, I can still use AVS-709 burned to DVD-R to set brightness and contrast, right? Just set it to 16-235 range; no practical reason to run BTB and WTW?

See ya. Dave
