Review on Monoprice Blackbird 4K 4x1 HDMI Switch with Audio Extractor - Black, HDR, 18Gbps Refresh Rates, YUV 4:4:4 by Justin Hines

I've bought a few other brands and have encountered issues such as the "" on the HDMI switch. This is odd as the same thing Volume down signal is quite common on TVs. I tried two cheap brands before settling on Monoprice and it just worked. It works with my Harmony remote or the tiny remote they gave you. I think it should be an automatic switch but I haven't messed with it, it's high speed and support for my monitor (3480 x 1440 @ 100Hz refresh rate) which was an important part as many of these switches don't go above 60 Hz work.
