multiple display

[MSPSTRANG]

I have several HP Elite Desk 800 Desktop PCs.  These units have Display port connections to a monitor and an HDMI Switcher.  The switcher allows a user to choose between the PC and an input plate for Laptop HDMI/VGA connections.  The problem is that after swithcing away from and then back to the PC as a source, the display priority changes and I can't get an image.  When I am able to get an image the promary and secondary display options have changed. 

I'd like to set the primary display as the monitor with video only and the secondary display as the switcher, which would carry video and audio, without any user adjustments.  I would also consider using VGA for the monitor and Display port-1 for the switcher.  Can I modify the bios settings, so that the PC will boot up and always stay in this configuration?

Which HP Elite Desk 800 is it?   Mini, G1, G2?

There have been many configurations of that model available in the marketplace.

Without your help in specifically identifying yours with its product number from the service tag that should be on the rear or side of the PC, it is almost impossible to answer your query.

My apologies.  These units are G2

Is it the tower, mini or SFF type HP Elite 800 G2?

A product number would have actually given me all of that information.
