Works ok, but seems finiky
Crutchfield Customer Review (What's this?)
The Metra CS-1x2HDMSPL3 4k HDMI splitter works. BUT, I don't think it likes being connected to a 4k TV and a 1080p TV. It works, but I have to unplug the 1080p HDMI cable when I want to watch only one TV. Otherwise, it either does not display anything on my 4k TV or my TV / directv receiver says "content not supported". Also, if I turn off the 1080p TV with the 4k TV still on, the 4k's screen starts to blink. Also, going from watching a DVR recording and back to live TV is problematic too. My receiver wants to switch to TV input instead of staying on Sat/Catv input 70% of the time. And 50% of the time the Metra loses "connection" to the TV / receiver / etc after stopping a DVR program. To fix it, I have to either unplug the HDMI cable from the Metra & plug it back in or I can change channel to sometimes fix it too. All this is why I'm giving it only 3 stars. I just wonder if the Metra or another one of my devices does not like "audio return channel" HDMI cables. Which is what I use....high speed, quality HDMI audio return channel cables with "ethernet" even though I don't need audio return nor ethernet... unless that's needed for 4k / 3D. My TV is 3D capable as well.
Pros: Price. 2 port 4k HDMI 2.0 support
Cons: HDMI Signal loss upon going from DVR recordings to live TV and vice versa. Main TV starts to blink it's screen after turning off the 2nd screen.
