Playing Digital Video Essentials, I find that I cannot get the 3 black pluges to show unless I set the "floating black" setting to 7.5 IRE (rather than the 0 IRE). Is this normal? - I cannot see how to set contrast on the Panasonic as the test screens seem to be designed for CRT. Is there a way of doing this properly? - What should the Gamma setting be on the Panasonic? 2.2? S-curve? - Should I use the AGC setting? - More generally, when should I change the DVD player settings and when should I change those on the plasma screen? This article describes a possible issue with the contrast setting on the US version of this DVD player.
