Atem Mini hdmi output to hdmi splitter

Every time i connect a hdmi splitter, i only get a black screen. if i plug the Atem mini directly to 1 tv, it works. as soon as i try to split and feed multiple tvs, the screen only goes black. tried new cables and multiple splitters with the same issue. Any advice would be appreciated

What is the Make/Model and specs of the HDMI splitter? Can it handle the resolution you are sending out of the Mini?

I have a few hdmi splitter from Amazon and some do not work on 60fps video.

I have two of these:

I got them because I was having issues when I would loop through one monitor to another. The key to making it work was that all 4 DIP switches (far right on the front of the box) had to be in th e"1" (up) position.
They work flawlessly.
