I thought id share my recent experiences with my new UHD box. I have a 2013 sony 4k tv and it turns out it is not compatible with streaming 4k content such as BT UHD and Netflix, so wasted my money as an early adoptor. So after help on the forums I decided to buy the latest Sony 4k TV (4mm thick and very nice I might add). Anyway I was keen to set it up and test out the BT UHD. It turns out i dont know if its 4k or not as the BT STB needs an update to transfer the resolution to the screen. My sky box works fine and shows the resolution. The freesat shows the resolution. SO, although the picture is good I'm not sure of the exact resolution I getting from the BT UHD STB. I bit disapointing as i would like to know if it really is 4k, because if its not I'll cancel. But i'm running out of time, really need the update MR BT!!
