Hello East
I purchased this receiver KI PLUS +T2 S2 Amlogic S905 Quad core 64-bit Support DVB-T2 DVB-S2 1G/8G 1080p 4K Android 5.1 TV Box Support to see how the UHD channels on Sats 101 and 103 would look on my Samsung 64 inch 4K TV, well they look very good and also the 1080p channels look very good, the tuner scan decent fast and of course misses TP,S like any receiver.
There is software out there and they claim is possible to add a external tuner, that would be great, I haven't look into it.
For the price it cost Can't complaint.
Regards.
Chewie
