What would be the ideal settings for watching DVDs and Blu-rays? I just read the Wirecutter recommendations for 4K Blu-ray players and they said the Panasonic UB820 had superior upscaling to the Sony X800, which I also have connected to my B7 LG OLED. I do have the UB420, but the upscaling should be identical since it has the same processor as the UB820, or so I would suspect. Yet, I find that the X800 is cleaner with less noise in the image and less ringing. I am just doing an evaluation by eye with real content, not using any test patterns, but it looks better on the X800. The HDR presentation does looks better on the UB420 though. As my evaluation disc for Blu-ray, I am using Batman The Animated Series. As everyone knows, it is a very dark show with large areas of dark colors. The Sony X800 has a cleaner, sharper image, to me. I played with the UB420's three different built-in profiles and I set it to the one with all options disabled to turn off the extra image processing.
