Monitor not reconize x2

this is my second x2 cant see anything on the monitor please help

I’m sorry to see you’re running into issues with your monitor and Webcaster X2. There may be a compatibility issue between your monitor and Webcaster. You have sent us a support ticket, so I will coordinate troubleshooting with you via that ticket

I have tried on 2 monitors all are 1080p
And nothing
1 using the HIMI cable provided by you connect to the monitor to the output of x2
2 connect mouse to usb port
3 connect power
Do I miss anything ?
