Access 27-xa0013w BIOS

[MattIITSTECH]

I received a 27-xa0013w from a client recently to use.  Hard drive was removed by them before I received the unit.  I cannot figure out how to access the BIOs.  The only thing that randomly pops up on the screen says "Check HDMI cable"  Haven't had it plugged into an external monitor at all.  I tried unplugging, plugging back in and hitting F10 but nothing shows up.

Hi:

You should be able to get into the BIOS but turning on or restarting the PC.

Immediately start tapping the ESC key to get the menu of options.

Select the F10 Setup option, and press the Enter key.

There are two buttons - One on the underside left front, and one on the underside right front. One is the power button, and the other is the the display toggle button (switches between the AiO display and an external screen connected via HDMI)
I think you're hitting the wrong button. I do it all the time when I have to use that model.
