I have a BenQ 6100 connected via a Denon 1803 receiver to an LG DVD/VCR Combi. I am using component video cables. I have noticed what I would call a problem while watching any fairly dark movie like the cave scenes in LOTR and a lighter object appears such as a face. The skin colour seems to have distinct shades with lines separating them rather than having a smooth appearance. This effect lasts about a second and then disappears. If the image moves these lines reappear for a second before disappearing. I have noticed this only on very light colours. I hope I am explaining this properly. Any ideas?
