Hi everyone,

I recently purchased a MiBox S 4K and have a problem I can't seem to solve. Although I'm able to watch 4k content through YouTube app, I can't watch them on Netflix (on which I am a 4k subscriber) and Disney - and who knows, maybe other streaming services.

It just displays HD icons on those two apps. I have changed my HDMI EDID settings to 2.0 and HDR plus 5.1 also showed but still no 4K. I bought a 2.1 HDMI cable and 4K icons showed momentarily but disappeared again.

My internet connection is 100mbps so I don't think it has anything to do with internet speed. The TV's (it's a Grundig 4K GDU 7900B, by the way) own smart TV system is able to display 4K icons on Netflix. So the problem has to lie with the HDMI ports or the MiBox itself.

I have tried everything. I don't use any soundbar or other bluetooth systems whatsoever - I have seen in a couple of posts in which people were able to solve it by disconnecting their bluetooth sound systems. I have three HDMI ports and I've tried each one of them to no avail. I have unplugged all HDMI ports and restarted my TV, again with nothing to show.

I'm just out of ideas. Is there any solution to this or should I give up and be content with 1080p on those two apps?
