Review on Monoprice Blackbird 4K Pro 4X4 HDMI Matrix Switch with EDID, RS232 Control, and Powered Connectivity by Chris Moody

This box has been in service for over a year, I bought it again just to be safe. In general it is very good to switch 4 inputs between 4 outputs. A few things kept it from 5 stars. The speed at which it can switch between inputs is a bit slow, but for the price it does the job well. The other is incidental. Sound signals that accompany input changes. I tried using the PC interface, which has an option to turn off the beep, but I couldn't turn it off. I believe the problem is with my computer and not the switch, and it wasn't a big enough issue to worry me. I will come back and try to change it again one day.
