AVISHOP 4x4 HDMI Matrix SwitchProAV Series - Seamless HDMI Matrix Selector with 4 TV Splicing Display Support 2x2 1x2 2x1 1x3 3x1 1x4 4x1 Video Wall Controller (4x4 HDMI Matrix Switch)

Exactly what I was looking forWorks perfectly as I had hoped. It is a true 4x4 matrix. You can redirect any input to any output or use the ALL / OFF buttons to quickly shutdown or project to multiple monitors / projectors. I did a bunch of research into a multi-input video switch/splitter. There was nothing even remotely affordable except for this 4x4 matrix. You can have, for example, a laptop and a AppleTV as sources, and four different outputs, such as 3 monitors and an LCD projector. Have an IPTV/cable input and an Amazon firestick input, and can feed those independently to the 4 TVs I have connected as outputs. One of my TVs is on a 65' HDMI cable, another is 55', 3rd is 35' and main tv is 8'. All perfect reception. Overall, it's a very good switch and it totally worth the price you paid for.
