So I have a Samsung TV that supports 4K resolution and I have the Roku Premier. I tried the Ultra but really had a hard time with it working properly. My question is, I bought a better HDMI cable and tried it a s the picture is ok but not what I picture 4K to look like. Does the premier version support 4K pictures (and if anyone has a a suggestion for a better on I will try it) and are there are any settings or tricks I’m maybe missing? Thank you!
