Warm 2 should be closest to the D65 white point that is the target for calibration. D65 looks wrong to a lot of people, because they're used to a cooler color temperature.
It is clear that my set had its Brightness setting set way too high (and I think I had put Black Level on Dark to kind of compensate). Just lowering Brightness and cranking up Contrast made a huge difference in the overall picture.
That being said, I can't make the flashing white bars disappear by raising Contrast in the white clipping pattern. Should I set Contrast all the way up to 100 in that case? Or is there any reason to lower it or another criterion to adjust it?
You'll never get rid of the white bars above 235 on this set. They don't hurt anything, and some are arguably worth keeping as explained in the Spears and Munsil articles I linked to. Setting Contrast to 100 maximizes light output (and audible buzzing), which you may not want to do. I use 67 on my 50ST60, which gives me about 38 fL on 2% windows, which is plenty for dark room viewing.
I let the TV input's RGB Color Range setting to "Auto". But if I understand your recommendation, you'd use "Limited" and accept crushed blacks and white on desktop apps and PC games?
Right, but I don't game on my HTPC. I just use it for video. If I gamed or did anything that suffered from this intentional levels mismatch, I'd compromise and use Full Range. (The ST60 calls Limited "Standard" and Full Range "Non-Standard".)
As for the general video card (nVidia in my case) output setting, if I understand correctly, you suggest using Full range so as to not squeeze the video range in a subset smaller than the actual Limited range, is that so?
Right, but that's for overall card output, and it's in the Display->Change Resolution area of the Nvidia Control Panel, option "Output Dynamic Range". This is different than the dynamic range option in the Video section, which applies only to hardware-accelerated video.
And checking the Limited range in Kodi is the right choice then?
A last question perhaps... if the settings above are the ones you recommend, then video playback using Kodi will be fine, but desktop and PC games will have crushed blacks and whites. But since the video cards outputs Full range, I guess switching the TV input from Limited to Full range would be a "single-setting" workaround for optimal PC gaming experience in that case? If so, I guess I could create an Activity in my Harmony remote for PC gaming that would change the TV to Full range, and revert it back on activity end...
That could work, but you'd need to verify you're seeing full range colors on the desktop using static images with bars ranging from 0-255. If you're not, then the settings you made for video aren't working for the desktop. Also, there's no discrete code for this TV setting, so your activity would have to navigate the menu system, which might be somewhat unreliable.
