Computer Will not Boot up Properly when plugged in HDMI on 2nd monitor

[Phenn2800]

My computer( the all in One HP desktop) works great when booting up and shutting down on its own. However, I am finding it incredibly difficult to trouble shoot my issue when my second monitor is plugged into via HDMI on startup. Normally, on its on the HP symbol would show and the login process can begin. However, when i bootup when its attached to my second monitor via hdmi it seems to not allow me to sign in and force me to restart the computer again and manually unplug the hdmi cord.

The weird thing is if i remove the hdmi, boot the computer normally, then replug the hdmi.. both monitors are working no problem.. which makes me believe this has something to do with the bootup process.

Any ideas on how I can get the computer to bootup with the hdmi cord still plugged in?

@Phenn2800 -- when two monitors are connected before power-on, the motherboard's settings determine which monitor is the "primary" monitor -- the one to show the "logon" screen.  

If you connect a second monitor when Windows is running, the "plug-and-play" components within Windows recognize the additional monitor.

With just one monitor attached, start-up the computer, and enter BIOS SETUP, to configure which monitor is to be the "primary" monitor.
