Videos only display a purple screen but audio still works
When I connect my roku 4 (4400x) to my Samsung tv (ru8000) with a certified premium hmdi cable, the menu looks perfect but as soon as I play any kind of video, the screen turns purple but I can still hear the audio of the video. Both the tv and roku are on the latest firmware. I tried switching hdmi ports, resetting the roku and tv, and even unplugged my tv for a few minutes which seemed to work for others with similar problems to mine but nothing seems to work. When I tried to auto detect the display type, the roku wants to set the display to 480p with hdcp 1.4 even though it’s fully capable of 4K with hdcp 2.2 but when I plugged the roku in an older 4K tv everything worked fine. I tried looking for any kind of solution but I can’t seem to find any. Any suggestions would be appreciated.
When the screen is purple, it is just blank regardless if the video is streaming through an app or playing through the media player using a hard drive. And every time I can hear the audio of the video playing. Something I noticed was the blank purple screen’s size will differ depending on the aspect ratio of the video
