Mirroring your PC’s display on a multimedia projector lets you output the computer’s display on both your computer’s primary display and the large screen associated with the projector. This setup is ideal for giving presentations where you may be controlling the presentation but won’t be sitting in a location where you can easily see the projector screen. Setting up your monitor and projector to mirror each other can be done in a couple of minutes with one or two extra components.
Connect a video cable to an available video output port on your laptop or desktop PC. If you’re using a desktop PC that doesn’t have a video output port on it other than the one you’re using, you’ll need to disconnect your existing video cable from the video output port, connect a splitter to the video output port and then connect the monitor you’re currently using to one of the split-off video output ports. PC video outputs commonly include VGA, DVI and HDMI.
Connect the other end of the video cable you connected to your PC’s second video output port to an available input on your multimedia projector that corresponds with the type of video cable you’re using. Alternatively, if you’re using a desktop PC and had to connect a splitter to your computer’s single video output port, connect a video cable to the remaining splitter connector and then connect the other end of the connector to an available input on your multimedia projector that corresponds with the type of video cable you’re using.
Turn on the multimedia projector you connected the PC to and then turn on the PC. Set the multimedia projector up to display the input the PC is connected to. If you didn’t use a splitter, the PC’s image will appear on your primary monitor and not your multimedia projector, and you’ll need to proceed to the next step. However, if you did use a splitter, the PC’s display will automatically be mirrored on the multimedia projector and there’s no need to continue.
Press “Win-P” to open a dialog box that gives you options for how to use the connected multimedia projector display.
Select “Duplicate.” Your PC’s display will be mirrored on the multimedia projector.
