Can I disable the PNP functionality on Windows XP?

Can I disable the PNP functionality on Windows XP?

The reason I want to do this is most of the time I have the computer plugged into a 52" LCD in another room displaying information. Occasionally I need to update the software and to do so I need to see what I am doing so I plug a monitor in locally.

"you don't want to disable Plug and Play, you want to disable the Display Data Channel (DDC)

On Microsoft Windows (Windows XP and newer), there is no software provided
option to disable plug and play
monitor detection. This causes
problems with computer/monitor
switching applications and causes
computer games to select display
resolutions higher than the monitor is
physically capable of displaying
resulting in a garbled display.

In these circumstances, it may be
necessary to remove pin 12 from the
monitor VGA cable, to disable plug and
play monitor detection. This allows
display resolution to be selected
manually and not overridden when the
display adapter is removed and
reinserted or the KVM switch is
operated.

the Pin # of course is different with HDMI or DVI connectors."

Just open up your Services window (Control Panel -> Administrative Tools -> Services) and stop 'Universal Plug and Play Device Host' and 'SSDP Discovery Service'. Also set their start-up type to Disabled.
