Hi all. This is my first time posting here. Been reading these posts for awhile trying to get clues to solve/reduce FB to a minimum on TC-P50G20. I think thru culminating data from other posters that I MAY have come up with a settings work around. No, it is not perfect, but does reduce FB by about 90% on letter-boxed BD content. I do not use this for broadcast HDTV (I am still working that out). Currently use D-nice THX settings for that. Only try this on a G20/25. I have no idea if it will work for any others!
So here is my procedure:
1. Use D-nice SM adjustments in the 2010 Panasonic Settings thread for the G20/25. Apply these before doing anything else. Plenty of instructions available, just search and you will find it. Simple and straightforward.
2. Use a 1.4 HDMI cable. I got mine from Amazon(Basics cable-$8)
3. Set BD player picture setting (if available) to Standard. I have a Sony BDP-S370 and it is available when playing back a dvd/bd under options/video settings. Output is 1080p, all other settings are at Auto.
4. Go to Custom on TV menu, and input the D-nice Pro settings, but change a few things below:
5.Now enter the following picture settings:
Color Temp-Warm 2
Color mgt/ x.v. color/ CATS- off
Video NR-Medium (to reduce noise introduced from high panel brightness)
Blur Reduction-on (to reduce noise introduced from high panel brightness)
Advanced Picture Settings:
Black lvl- light
There you go. Should see quite a reduction in FB, with only a slight degradation to overall picture quality. I still have ambient room lighting on, since without it FB will be more active/apparent. I found that by dropping the brightness, I can lessen the effect even more, but the pic gets grainy and darker. I did still find it acceptable at 51, so play with it if you like. Contrast can be brought up if you like. I had it at 68 and found it to be grainy on DVDs but OK on BD. Settled on 66 as a good compromise.
As a final note, I still use D-nice THX settings for 1:85/1 aspect ratios (full screen 16x9) BD/DVD material. This setting is just for narrow letterboxed content like Matrix/Inception/The Dark Knight.
Good luck if you try this. No promises, but it did help me on my 50G20!
