BTW, I double checked the HDMI Black Level setting today. On low, it is definitely crushing black. On normal, it isn't, and you can still see the full range such as white 236 to 255. I personally don't think this setting has anything to do with RGB limited or full range. I think it just adjusts the gamma to a degree maybe changes it to a different curve. It may
be a setting you'd look into to calibrate for deeper blacks, but again you'd be correcting a gamma curve so you may end up defeating it anyway and might have an easier time calibrating for normal.
Something of note: PC mode will not allow YCBR ranges beyond 235 or below 16. In PC mode, However, I can create an image with a 235 white background and 255 white text and make out the difference. Really, really weird. YCBR will also float the blacks, but going into menu and moving the brightness slider down 1 notch and back up a notch will pop the image back to how it usually looks.
Could someone else test this? If it's a repeatable bug, then I'd like to report it.
In PC mode:
Step 1. Set PS3 to RGB for DVD/BD content.
Step 2. Load up the 5% grayscale step pattern from Get Gray
Step 3. Hit triangle, go to AV settings, change the output to YCBR.
Notice the image pops up in brightness.
Step 4. Hit menu on your remote, go to brightness, and change it by a step.
Notice the image resets to it's normal setting.
