So in the last 3 years I didn't notice that my Roku only played movies in HD until recently. I was so tired I didn't care. Then one day I decided to watch a SIF movie in UHD and set about setting it up. There was no choice for that. After investigation, I discovered that I was not using HDCP 2.2 certified HDMI 2.0 cables. I checked out Best Buy and WOW they were expensive. So I found them and saved a lot of money. I plugged them in, the system recognized them from device to device to TV. UHD showed up and everything worked great. These cables touched me on all buttons: quality, cheapness, reliability. You will hardly find anything better in this price range.
