I've just set up my first plasma which is a TH42PE50 for the bedroom before I get a 50 HD panel for the living room I noticed from the off that the picture was absolutely stunning and had it set to about 25% on both contrast and brightness. I'm not officially doing a super quick runin since how I like the picture is obviously fine, I'm just avoiding logos. After about 40 hours the phosphors seem to be glowing brighter than out the box and the picture doesn't seem quite as good or it may just be me? I have the constrast on about 20 and the brightness on 0 now and the whites still seem washed out. Will this subside after the 200 hours?
