I notcied in the newest firmware from intel the limited/full setting has dissappeared. Maybe they are trying to fix the issue with the Full setting reverting to limited once you restart.
Will this hack give me the black level my tv is capable of?
All Panasonic TVs are using 16-235 video range while PCs normally use 0-255 PC range. But if you connect PC to TV via HDMI, most video card will convert PC range to video range on HDMI port. Some video card let you pick output type. Some may not. On the PC side of things, Windows desktop and most applications output full PC range, including WMP. However, Windows Media Center by default output limited video range. I'm not sure how a HDMI output of the video card will do to the WMC default output (convert twice?). I always apply registry hack to force WMC output full range because I typically use PC monitor for viewing and NEVER use TVs for my PC to avoid such confusions.
There is no fool proof way to guarantee the consistent color space matching between PC and TVs. Just remember, all regular video sources are encoded as limited range. TVs are typically designed to handle the limited range, any conversion to other range will introduce unnecessary conversion artifacts in the middle.
