Question No output to the monitor after tinkering with the bios settings

[jimhanks]

I was tinkering with the bios settings and especially os defaults. It was set to Win 7 (I am using Ubuntu 18.04) and I changed it to manual alongside the fast, and secure boot options, that I changed to enable. I saw a text with 'VGA' on it in the settings after I changed to manual, but didn't pay attention, after the restart, my HDMI only tv that I use as a monitor, didn't post (no signal), I don't have a VGA monitor that I can connect and try. Here are the steps I tried:
-Take out CMOS battery and put it pack in
-change graphics card
-change HDMI port on tv
But no result. That being said I did not have any issue with graphics, so my monitor, HDMI cable and graphics card is working
Is it possible to solve this problem without a VGA monitor?
also my motherboard:
ECS h81h3-m4

I reset Cmos but still no luck, I Changed the jumper and left the battery out for 5 mins.
