I have just bought a Philips 58PUS8536/12 tv, and when i try to watch something either on Netflix or Prime video, the image quality sucks due to HDR (all the shadows are red and yellow and everything else is too red). I tried streaming the same content from my phone and the image is much better, but it's not 4k. Is there a way to turn off HDR or do i have no choice other than returning it? PS: i tried fiddling with the picture setting for 3 days now.
