Sorry I have to be so vague about it.īut as others have said, you ought to just buy a second monitor (and video card if necessary).

DVI-D), there's no way around it but a hardware implementation of the digital logic that needs to happen between the monitor and the PC. If you're using an analog (VGA) monitor, then the solution is extremely easy: just put a couple resistors on the connector (one of many examples at this forum). I've actually done a lot of research on this recently, because one of the products I'm working on requires a second monitor to be available for remote control of a computer - the primary application on the computer takes over one of the monitors, so the user needs a second desktop to work on.īoth of these approaches assume you have a free video card that won't output video unless a monitor is connected: The shortening of ANY connector on pc can cause malfunctions so be VERY careful and doublecheck EVERYTHING! You have beying warned ) Good luck and sorry for any spelling mistakes i made. I did cut off old VGA cable connector and strip it apart, used soldering and hot glue to make sure it will not shorten the connector. To view the desktop you can use any remote control program even the native one, and see whole desktop on dummy VGA AAAAND secondary monitor that is REAL :) Hope that will be helpful for someone. The resistors works as and answering mashines and if GPU sends R/G/B signals it is transfered to receiving pins and fooling the GPU that is actualy monitor on that VGA port connected. The tricky part is that when you disconnect the main VGA monitor the whole desktop is set to the HDMI and whole secondary monitor trick just f***s up, so i made a quick search on the internet and found way to trick GPU to think that it is actual monitor connected as VGA and set that to default desktop and do not transfer desktop to the HDMI. i have school TV setup that needed an external HDMI audio/video output as secondary monitor on windows xp system. I found cheapest way to trick pc by physicaly making an dummy VGA (XGA,RGB) analog connector by simply putting three resistors from 50 up to 150 ohms on some connections.
