You either need to use PC levels in CalMAN, enable the expand video levels to PC checkbox, or use RGB Full range from your video card.
There are many different ways to skin this cat. Many of them work correctly, many of them don't work.
Super bowl day, I don't expect you to be waiting for a reply.
I have read countless threads bout HTPC and WHAT IS RIGHT.
I also a few years ago rented a TPG from one of Calman divisions to test my card.
Using "vid" setting in Calman to get the proper triplets.
Used a LCD without any fancy backlight trickery.
The pattern gen and vid card were bit on.
That is using both 4:4:4 and 4:2:2. 10 percent windows, no apl.
I found an old workflow session where I found a plasma was reacting differently to different Hz 30, 24, 60 etc.
I used both my laptop vid card, (notice 29 Hz Not avail on Bluray) and Bluray set to 60i and 24P. The gamma curve changed.
No changes were made to TV.
0 black was repeated and .005 is as black as it gets. I used THX and Custom mode also. Point, bluray and vid card agreed for the most part and mainly 0 black/16,16,16 was 0. (Since AVS rounds wrong, a little off is expected)
This work flow was made in vid 16-235 setting in Calman.
If you change the mode to PC 0-255 the data disappears. Kind of a lucky break to show how no trickery was done by me.
I took a little time and ran 3 measures on the LCD mentioned.
Card set to Ycbcr.
1 run was made by media player mp4 patterns with calman set to vid 16-235. 0 black agreed with a run using the pattern generator
set to PC 0-255 but 10 percent up was way wrong.
1 run was made with pat gen PC mode
1 run was made with pat gen vid mode
why will media player (windows) show 0 black and up correct but not Calman?
Frankly I don't know what happened or when. Windowws update? maybe. Don't have time to get into it.
All I know is at one time my vid card and a rental pat gen agreed.
the calman session is too large to upload. pm me an address.
