This does not work for Windows 7 dual displays. &nbsp;I'm pulling my hair out because I've spent hours trying to correct this. &nbsp;I use UltraMon and I can not get UltraMon and Windows to agree on which monitor is number 1 and which is number 2. &nbsp;I really wouldn;t care except that when I RDP into this machine (even with monitor 2 disabled) RDP connects to the black/blank screen (#2 for UltraMon but #1 for Windows 7). &nbsp;Urgh.

Yesterday, something changed in my system that caused my primary display device to now show up as Display #2 in the Display properties dialog. &nbsp;I don't know if it was because I docked and undocked the system, added then removed a second monitor, or I modified the display presentation mode with Lenovo's display settings.<br />
<br />
How do you assign the display number in the Display Properties dialog?<br />

Change monitor number is display properties

A monitor or a display is an electronic visual display for computers, usually comprised of the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors used a cathode ray tube (CRT) about as deep as the screen size. They are connected to the computer via VGA, DVI, DisplayPort, Thunderbolt, LVDS or other proprietary connectors and signals.

Microsoft Windows XP is the sixth release of the NT series of operating systems, and was the first to be marketed in a variety of editions: XP Home and XP Professional, designed for business and power users. The advanced features in XP Professional are generally disabled in Home Edition, but are there and can be activated. There were two 64-bit editions, an embedded edition and a tablet edition.
