  • Color banding - pc to oled c8

    Hi,
    I'm connecting my pc to the oled c8 via hdmi. I notice significant color banding in certain scenes while watching 4k hdr movies. These banding do not exist when I play the movie via usb using the internal media player of the tv or even the free vlc 3.0. Any idea?

    Banding on LG OLEDs
    The banding a lot of people are seeing on the LG OLEDs is apparently a bug in the image processing. If your UHD player has the relevant setting it can easily be fixed. Do not use YCbCr 4:2:0 or 4:2:2. Use 4:4:4. I was seeing a lot of banding in the otherwise reference disc, The Revenant. When I switched from 4:2:2 output on the UHD player to 4:4:4 all of the banding instantly went away.

      Experiment with the Video settings in Player as shown below,particularly the output color range. Also try the Analyze Hardware button to see what it finds.

            Sorry for the late reply. Here is the log file: Log.rar

            You can easily notice it during the netflix opening with the red Netflix logo popping up on the white background (mine is Luke Cage S02). The color banding can be seen at the corners of the screen. Actually I see this issue on vlc and win 10 movies & tv app as well, but on dvdfab it's the most severe. My tv is lg c8 oled; the tv is connected to it via hdmi. One more thing: playing the file via usb using the tv built-in video player showing no banding.

            Other movies that I have noticed the banding include Transformers The Last Knight and Assassin's Creed. The banding can be seen on the sky.
