I saw someone say the flicker adjustments help
VB, to do those you need to access the "secret menu". Highlight "OSD" in the "Options" and hold down "Select" or "Ok" on your remote until a new menu appears. Go down to "Flicker Adj" and through 6 RGB flicker screens (2 of each colour) left and right adjusts the flicker level up and down to go to next screen. Press Menu when you are done.
This is certainly worth doing to reduce flicker, I'm not sure if it affects
VB much, I guess lowering the contrast a little may help
VB, best to do that with Avia or similar.
