Upgraded from a Premiere to a Roamio but didn't account for the HDMI-only output. My TV has just one port and I use it for Apple TV. So I need a switch. My research has shown that the choice of a switch is not simple. Based on reviews, some switches just do not work with some devices. Even looking at the reviews of a specific monoprice switch I see many users saying it works with ATV, Chromecast etc and others say it does not! Some users have required a powered switch, others have not. If you use your Roamio through a switch I'd really appreciate a specific recommendation. Extra credit if you're switching a Roamio and an ATV!! Thanks much for the advice.
