Can't get RDP Session to Span Across Two Monitors - Windows 8.1

Hello Experts,
I cannot get my RDP session to span across two monitors. I have tried various adjustments in the parameters of the RDP connection, such as: use multimon, span monitors, manually assigning a desktop width and height, screen mode, etc.  There is an issue with my how Windows identifies my monitors: I have only two monitors, but it shows that I have three. The monitor being identified as monitor 1, is not a monitor that is actually displaying anything and its resolution shows 640 x 480, while monitors 2 and 3 are displaying at resolution 1920 x 1080. I tried disabling the monitor that is the 'ghost' monitor in the device manager and unplugging/restarting the computer, but there was no change. What I most need is for my RDP session to span my two monitors, I don't care about the ghost monitor unless you think it is causing the problem with the RDP session span...
I much appreciate any help you can give me with this.
Respectfully, Chop

Save the RDP connection on the desktop. Open it with notepad and you should see the following:
screen mode id:i:2
use multimon:i:0
desktopwidth:i:1920
desktopheight:i:1080
session bpp:i:32
........

Modify the first two lines and save:
screen mode id:i:1
use multimon:i:1

I hope this will help.

I have tried all of those steps already.

I believe the problem may be related to the fact that Windows is seeing an extra monitor. Do you know how to access the bios on my HP Envy, system model 700-214, in order to disable the onboard video card? I've already tried using pressing F2, F6, F10 and the escape key on start-up.

I am remoting from Envy.  When I use a different computer (not the Envy) the RDP connection does display on both monitors. (The remote computer is not the problem.)
I've already tried using the keys you listed for displaying bios.
As I can understand you have attached another screen to your laptop and currently you can see a replicated screen on both monitors, but you would like to have extended monitors and on one motirot to look at your Envy desktop and on the other monitor the RDP desktop?
If that is right then, you should play with your Windows display settings and select extended screen for the second monitor.
