im asking this for my son who just had an HS17 install last weekend. I went to 105 and there was a banner that said this tv doesn’t support 4K so the program was in 1080P. I went to settings and under Diplay-TV resolutions, 4K was unchecked so I checked it and it acknowledged that the tv did support it. The next day they went to view a 4K channel, they got the same problem. Today I was over there and went to the golf game on 106 I believe it was and got the same thing again. Anyone know why the 4K won’t stay checked? It doesn’t take long to correct it but it won’t stick and kinda aggravating.
