It just happened on another board.

Interesting, when I use my 19" HP monitor, the error message says something different:

Input Signal Out of Range
Change Settings to 1440x900 - 60 Hz

This is extremely frustrating. Obviously, I shouldn't have upgraded the UEFI (BIOS) to v3.0.

Your help is greatly appreciated!

Thanks,
Gregory

My System consists of

X570M Pro 4
Ryzen 3700X
VENGEANCE® LPX 32GB (2 x 16GB) DDR4 DRAM 3200MHz C16 AMD Ryzen Memory
CRUCIAL MX500 2.5" 1TB SATA SSD
MSI GeForce GT 710 1GB LP V1 Video Card

I upgraded the UEFI to version 3.0, and now when I go to install an OS (RHEL 7.8), it gets part way and then video stops working, with a message that input is not supported. I am using a simple vga monitor (happens with 2 other monitors as well). When I tried using HDMI, the screen just freezes

I removed the CMOS battery for ten minutes, but same thing. I downgraded the UEFI to version 2.30, which was on the board originally, however, it is still happening.

I tried to go into the UEFI shell, but it says there isn't one.

I tried putting in a second GT 710 card, from another working system (exact same setup), and it still turns off the video with the "input not supported' message.

I have three other systems, with the exact same configuration, however, on this one something appears to have been corrupted, and installing/reinstalling the UEFI is not fixing it.

I have run out of ideas how to rectify this problem, and get this motherboard working properly again. Your assistance is appreciated!

Best regards,
Gregory
