Review on 🔀 goFanco Intelligent 4x4 HDMI Matrix Switch 4K 60Hz YUV 4:4:4 HDR with Auto Downscaling (Output 4K & 1080p Simultaneously) & Alexa Echo Voice Control, HDMI 2.0, HDCP 2.2, 18Gbps, IR, RS-232, Control4 by Tony Trotter

Easy to install. Worked as stated. A bit slow to switch from one source to another, but otherwise works well. I wish it had a "blank" function to send a blank signal to the output instead of just muting which isn't sending a signal leaving the connected projector dark instead of with a no signal message to shine. Edit: My rating was downgraded after realizing that the computer's input doesn't recognize it as an audio-over-HDMI capable device and therefore can't enable audio output from the computer's graphics card. Edit: Upgraded my rating to 4 stars. Technical support was very persistent in getting the product to work in my environment. They replaced the non-working unit with a new working one. The willingness of their technical team to help make this product work is a huge plus. Although we ended up using another product that came out of the box and offered additional features like video blanking and seemingly less switching, this product's value for money is worth it if you're willing to put up with the fiddling and fine-tuning to spend. so it works fine. Especially in a non-manufacturing/residential setting.
