I have a TCL Roku TV. On certain channels, such as the NFL app and NBC Sports app, the resolution of the video picture is slightly off. It is not the high quality HD video that I had with DirecTV. I have HDR settings turned on and the picture setting is turned on to "Sports", but the video reproduction quality for the channels that I mentioned are almost a film-like quality, not HD. I should mention that some apps, like the NHL TV app work fine, perfect HD quality. I have the TV connected directly into my network (i.e., wired, not wireless).
