Advertisements I just hooked up a Polk Magnifi Mini via HDMI arc on a new 2020 TCL TV. Using ARC should then enable all audio from all other connected devices to use the soundbar. The sound bar works great via the TV and the built in Roku apps. Sync is great. No problems at all. However, when I try my Tivo Roamio, the audio plays fine but the video almost has a lagging / ghost like trailing effect (I'm trying to come up with the right words, it's like the mouse cursor trail effect you can change in Windows settings). I have the Tivo hooked up via HDMI to the TV. Any suggestions?
