Video multi question

Archived from groups: alt.comp.hardware,comp.sys.laptops,comp.laptops (More info?)

This may be a strange question but; I use the a multi monitor function
with my laptop and run a certain piece of software. When traveling and
using this program, it requires a 2nd monitor to be plugged in to get
the 2048x768 resolution which is required to run the program. Is there
a way to fool the laptop into thinking there is a 2nd monitor
attached, maybe a plug with a resistor accross two of the connections
or something. Any suggestions would really help. Best regards and
thanks for reading this...
