Does it support 4k@60? Can you configure EDID handling, or any potential HDCP issues (and stuff like HDR, ethernet-over-HDMI, etc)? Would be curious what make/model of matrix you're using.

There's plenty of different hardware out there but not a whole lot of reviews; and my experience with the HDMI interface has, on the whole, not been the best. HDMI is great for consumer stuff, and for plugging in a generic source to a screen (AppleTV, Firestick, Xbox, cable box, etc) -- but, as soon as you want to do anything even slightly more advanced, you often run into hiccups quite rapidly (EDID & handshake/negotiation issues, cable & port quality, HDCP, etc).

I have several 'screens' (TVs) and I wanted to be able to mirror my 'main' display to other screens on occasion, for instance. It's easy to do that with a cheap-ish "splitter" [though they are finnicky), but if you want to "scale" that at all then you rapidly run into proprietary and/or high-cost solutions or have to make substantial quality & capability concessions (and >=10G LAN connectivity is pre-existing).

I was annoyed by the lack of good options & and the extreme prices and/or the limitations of the options that do exist -- enough so that I'm working on (and already actively using) my own IP-based "video distribution" solution, heh.

The 16x16 one I bought does. It supports (some form of) HDMI 2.1. The EDID management for all matrices I’ve tested is a bit odd. Pass through doesn’t always work with most monitors, and you can specify a generic EDID from a preconfigured list, upload your own (only one) EDID file, or select “COPY_FROM_INPUT_1” for any or all outputs. The problem is that sometimes you might want input 1 to go to output 2, despite normally sending it to output 1. I have to manually change the EDID profile.

I can’t say how well a balun/extender setup will work but I believe they make boxes that specifically do that - a combination matrix and extender. I have no issues with HDCP. Happy to answer any other questions.

Search Monoprice for Audio/Video splitters but pay very close attention to the description. Make sure you understand the number of sources and sinks it offers.

Also note my response to the other question.

Also please let me know if you find or know of a better USB switcher! I want one that supports 4 inputs but can handle more than 4 outputs to switch between. 6 or 8 would be great. It’s very handy because I frequently have client laptops or I’m working on another computer or RPi, so a spare USB input that I could leave on my desk would be great.
