Early Extron 1080p max HDMI matrix: doesn’t work
Kramer 4K60 matrix: doesn’t work
Key Digital matrix: WORKS

but yeah, I also suspect EDID behavior here.

Also the person who runs misteraddons was kind enough to reply to me:

from what I hear many of the HDMI matrix boxes don’t pass direct video. I don’t believe it’s a CEC issue but I don’t know that anyone has pinpointed the exact reason.

Oh that’s interesting. I’m running everything through this (admittedly) lesser-known hardware because it handles everything in 4K and has a lot of ports. I might segregate my setup into 1080p stuff through an Extron and leave just the 4K specific stuff to this device.

The Extron SMX I use passes DV/DV1 through. Can't speak to JTech (first time hearing of the brand).

Interesting…which SMX are you using? Is it one of the DVI, or a proper HDMI? Can it do 4K?

Is there a way to get a professional 4K matrix to passthrough a MiSTer Direct Video signal on HDMI? If I connect the MiSTer directly to my RT4K, Direct Video works just fine. But when run through a JTech 8x8 matrix, the signal doesn’t come through. Are there some EDID or other settings to make the matrix not interfere?
