I have a Samsung Q80R TV with a maximum resolution of 4k, using Nintendo Switch or Wiiu in 720p or 1080p resolution with a beautiful upscale to 1440p, but when I lower the resolution to 480p the problems start. The image shows interference, there are several colored stripes on the screen causing even the signal to be lost, the screen flashes making it impossible to play. However on TV that is only full HD this does not occur. Has anyone been through this? Managed to solve?
