"Mode Not Supported" -- suddenly won't play Netflix
I have a Roku Premiere+ (Model 4630X) and for the last couple years I've played it on my Samsung 4K TV with no problems. A few days ago, I stated getting the below error screen whenever I tried to play something on Netflix. If I unplugged the Roku and plugged it back in, though, it would work. Today even that isn't fixing it and I can't get it to play Netflix at all. It will stream YouTube TV just fine, though, which is also through Roku and is using the same HDMI cable and port.
I went into Roku settings and had it auto-detect my resolution, which it correctly set to $K HDR at 30Hz HDCP 2.2.
Re: "Mode Not Supported" -- suddenly won't play Netflix
We have had the same issue with a Roku Premiere and Samsung TV. We’ve used it for a year and yesterday we got the message “Mode Not Supported” - I can’t even get to the Home Screen to look at the settings or update. The screen is black with the error message. I have unplugged everything several times- nothing works! Help!
