For warranty cover/full support, stick to the one provided, as if anything goes wrong with the non-DroidBOX update offered, our bean counters might try to argue that it wasn't a procedure we said to follow.
On Samsung 4k TV's you may have to enable UHD colour for each input, in picture options. Not all inputs, depending on the model, will have this option.Well I am not further forward. I have now got a 21gbps version 2 cable and the issue continues where I can only setup 1080 or 720 resolution. I have tried all hdmi ports on the TV and checked the tv manual which states that all 4 ports can support 4k 60.
I feel I have taken over this thread and not helped PeteA with his issue as originally I was interested in his 4k setup. I am willing to help but until I can configure the T8 to 4k to my TV I can't be of much use.
I will trigger the remote help and see what that brings unless anybody has more ideas through here.
