Guys, I just noticed last night while watching Bourne Identity that there was indeed flickering on my Hitachi panel. The flickering occurs on dark scenes. Very strange. Care to shed some light into this matter? TIA.
I also noticed this contrast fluctuation with my 42PD8500TA. First when I watched Jarhead. It usually happens with dark scenes with with some bright parts. But it is not true for all movies I've watched so far. It seems that it depends on the source too.
What I did, as what I have read at AVSForums, is to set the Black Level Enhancement to LOW, turn OFF Luminance Manager. Set contrast at or little lower the middle of scale.
With HDMI, this "flickering" is minimized or eliminated depending on the movie. I watched Jarhead again, the movie where I first noticed this "flickering", and watched the scenes where the I noticed it, and I don't see the flicker anymore.
With HDMI connection, Black Level Enhancement is set to OFF. Contrast setting is still at Mid or a little lower than Mid. Luminance Manager is still OFF.
Another movie that I noticed this is with Mirrormask. The scenes are a mix of bright, shining/shimmering effects, plus dark parts. Flickering is less with HDMI than with Component connection.
