We just bought a new Roku Ultra to use with Youtube TV on a Vizio TV that is a few years old. For most shows, everything is fine, but for live sports (e.g., NBA) the picture quality is horrible. If I cast from the Youtube TV app on my phone to a Google HDMI dongle, the picture quality is perfect, but if I plug the Roku into that same HDMI port, the quality is bad. Could it be the HDMI cable? (I'm using the one that came with the Roku)
I looked through all the settings menus on the Roku and TV, but couldn't figure out anything to change. When I was disconnecting and reconnecting the HDMI cables, I did get some kind of message about incompatibility, but it went off the screen and I couldn't read it.
Or is there some incompatibility between the Roku and my TV?
I've hunted around online and still unsure how to proceed.
Thanks in advance
