Okay, wondering if anyone on the forum can shed some light on this problem I seem to be having. Purchased the Panasonic Viera TC-65DX800C and am enjoying it immensely with one caveat. Occasionally, I seem to be getting a queer 'ghosting' of the red record while uprezing Blu-ray content from my Sony BDP S6200. The BDP S6200 has a 4K uprez built into it and the TV is, of course, brand new and 4K. Tried adjusting various PQ settings to get rid of this but to no avail. I can minimize it somewhat if I boost the backlight feature on the TV to nearly 100% but this makes the entire image too bright for my tastes. The issue, if I can describe it is as follows; a sort of ghosting, usually - but not always when the color red is present; a red halo around people, objects, etc. Flesh tones are particularly notorious, during darkly lit scenes, but there have been a few instance where brightly lit scenes suffer too. Example: Funny Face - the 'think pink' number, the girls dresses and hair have a sort of red ghost shadow whenever they move, which is always. Don't really know what to do. Wondering if it's my cable. I confess, I haven't upgraded to a 4K HDMI cable yet, having only had the TV a week, and am still using my old HDMI cable. It had no such flaws when it was hooked up to my old non-4K set. Thoughts, ideas. Recommendations on new cables if they are needed. Again, thanking everyone in advance for their insight and help. PS - please, no recommendations to buy a new player. I have every intention of going full 4K when Oppo irons out the kinks from its debut player later this year and includes Dolby Vision in its hardware updates. Thanks again.
