How It Works
With all its colors and inputs in the back, your projector may look complicated, but it only needs two things: power and video.
The power is connected to an outlet in the ceiling, so it hardly ever gets unplugged, and it uses the same cord as most computers and monitors, so it’s easy to replace. The video comes through two VGA cables. One from your computer/dock to a panel in the wall, and another from the ceiling to the projector. (It is possible to connect other inputs, such as a DVD player or a Miracast. If you do, you would switch between them with the “Source” button on the remote.)
Note: Your projector has nothing to do with your sound or the pen. Those come through the board, and are physically separate. The projector doesn’t “know” what it’s showing on.
- The most useful button on the remote is A/V Mute. It blanks out the screen without turning off the bulb, so that you can turn the display off and on without ever waiting for things to warm up. Use it often.
- The most useless buttons are the Volume Up and Volume Down. You will probably never use the projector’s speakers, so these do nothing. Control the volume through the board or computer.
- You should never need to manually change settings related to display, position, color, etc. Turn it off and on again, and it will automatically adjust.
How It Breaks
The power almost never goes wrong, so that means any problems the projector encounters are probably related to video. Maybe the cable is bad, or loose, or in the wrong spot. Maybe the computer is not sending a signal through the cable, or more likely, it’s sending a signal but not the one you want.
More rarely, the projector is getting everything it needs, but it is having a problem itself. The parts are clogged or overheated, or the bulb is dead.
How to Fix It
Make sure video is connected: the VGA cable is connected to the computer/dock and to the panel in the wall, tighten the screws. (If the color is weird, this will fix it.)
Make sure the computer is set up: Right-click the desktop, go to Screen Resolution, and make sure the screens are enabled, arranged, and set to duplicate or extend, whichever you prefer.
As always, turn it off and back on again.
If neither works, look at the projector itself: clean the filter, check the cables, or replace the bulb. If none of those work, or if the projector gives you an error, contact us.
