Preview ATEM Mini doesn't work

Hi. I need a help!

I'm trying to view the ATEM Mini preview on a monitor. But, I connect the HDMI to the ATEM Mini output and it doesn't show anything. I've changed HDMI cables several times and it still doesn't work. Any suggestions from support? Thanks.

The reason is probably that the video format you are running the switcher in is not supported by the monitor.

What format are you running it at and what is the model and brand of monitor?

In fact, it's not a computer monitor but a Samsung TV - model BE32T-B. I've already tested the HDMI output on a splitter, and none of the lights came on. And also, I tested my Samsung TV on a splitter and it supports several resolutions, both 1080p and 1080i. I suspect the HDMI output is broken.

I've already restored factory settings, updated to the latest software and nothing. It still doesn't work.
