From my understanding, the HDMI Black Level on Samsung tv's is as follows:
Low: 16-235 (limited)
Normal: 0-255 (rgb)
I did a comparison. I set the PS3 to Limited and the black level to low. Then I set the PS3 to RGB Full and the Samsung black level to normal.
The picture looks basically the same to me on both configurations. Which is the preferred setting to use? What setting is best for Games and Blu Rays, since i use the ps3 as a blu ray player?
