POST and Bios on HDMI Display

[RichSchnieders]

I have an HP Pavilion Gaming PC 690-0067c. I need to replace my boot SSD and have attempted to bo to USB with Win 10 install on it. But I cannot get the PC to enter the bios setup to set the boot order so the USB is selected. I have 2 ACER HDMI monitors connected, one via the HDMI port and one via the Display or with an HDMI monitor. 

I never see a POST on the screen or a bios screen. I have attempted using esc, f2, f10, to enter the bios setup on boot. none of these work. 

Is it possible that POST and Bios do not display on an HDMI monitor? 

How can I get POST and Bios to display on HDMI or do I need to hook up a monitor to the DVI port?

Any help would be appreciated.

Thank you in advance for the help!

Hello
i don't have the same computer so that doesn't prove anything, but:
I have already entered the bios, while the screen is hdmi
I have not done the test since adding a second screen ..
Tried at least by disconnecting the second
To open the menu, you must turn off the pc (a restart may be too fast)
As soon as the start button has been pressed, press the f10 key several times, the menu should be displayed

but as we can see in this document it can be of other keys

I ended up having to connect a different monitor that had a DVI connector. I do not see POST or the Bios setup via HDMI. Once I connected a monitor via DVI I was able to make the changes and replace the SSD.  All good now.  I would like to see POST and Bios via HDMI but it is not critical. 

Thanks for the help!

It's curious, all my hp computers were connected via HDMI, when possible, with an HP or acer screen, and no problem going into the bios ..
Have you tried one or the other screen (alone) in HDMi, changing the cable?
If you want to close the wire, do not forget to mark it, it can be used for other
