What is the switcher?

The switcher is shown in the picture below. The switcher is used for switching between showing the laptop screen or the desktop screen. To switch between projecting one of the two screens, just click the center black button in the middle once.

If your computer or laptop is on, by looking at the projector screen you can look to see if your screen is being projected. If it's not being projected, the switcher is more likely on the wrong setting.

The plug-in cords on the switcher are HDMI cables, they are labeled for your convenience. There is one cable that is not plugged into anything, and it should be labeled laptop. That cable is used to plug into a laptop for projecting it on the screen.

* Please Note: All the switchers work by having the correct HDMI cable plugged into the right places. Please do not remove the HDMI cables from the switcher or plug it in to different areas, as it can lead to issues such as not projecting anything at all. *

How do I project from my device to the projector

Desktop Projection - If you want to project what is on the desktop to the projector, you first need to ensure the switcher is set to display the desktop, and make sure the computer is on. See "What is the switcher?" for more details.

Laptop Projection - Plug the HDMI cable labeled Laptop, into your computer. Ensure that the switcher is clicked to project the laptop screen. Once those steps are complete, your laptop should be ready for projecting. See "What is the switcher?" for more details.

* Please Note: If the devices are still not projecting, then it is possible that the projection settings are not correct. If this happens, try Windows Key and P together, as shown in the image below. Then select duplicate to mirror your screen or extend to have it act as two separate screens. *

What if the classroom computer is off?

There are two factors that play into why the computer is not showing anything on the screen or looks to be off. The computer screen could be off, or the computer tower is off. Sometimes it could even be both cases. To quickly fix the issue, check the following places.

1. The Computer Screen
• The computer screen should ALWAYS be on and never be turned off. To check that it is on, check for a light on the screen itself.

• The blue circle in the above image is the power indication light. The different light colors could mean:
• Orange/Red Light - Sleeping (Shake the mouse to wake)
• Green Light - On
• No Light - Off
• If the screen is off, press the power button shown inside the red circle in the image above.

* Please Note: Some computer screens have different mechanics/styles, but the same symbol and rules still apply. *

2. The Computer Tower
• If the screen is on, next check to see if the computer tower is on. The tower should ALWAYS stay on and never be turned off. To check that it is on, check the power button on the tower.

• The red circle in the above image is the power button. There is typically a light within the button. Different lights could mean:
• White Light - On
• No Light - Off
• If the computer tower is off, just press the power button once to turn it on. You should see the power light in the button turn on, and the computer screen will also light up if it is on.

* Please Note: The blue circle in the image of the computer tower is the location of USB ports. The layout of the power button and USB ports may be different for different computers, but the same rule apply when checking if a device is on. *

What if I have a USB device?

If you are using a laptop, all you have to do is plug the USB device into a USB port on your laptop, then it should pop up for use once logged in. Most laptops have USB ports on the side of the device

If you are using a desktop computer, plug the USB device into a USB port on the computers tower. The device will pop up for use once logged into the computer. Most desktops have USB ports on the front of the tower.

What if I have a DVD?

For a DVD, you will have to use the desktop computer, unless you have a digital version for the desktop or laptop. The DVD player is shown below for reference. If the desktop is on, the DVD player should be working as well. To put in a DVD, locate the button circled in red in the reference image. That is the eject button. Click it to open the disk tray, then gently push the tray back in to close it.

Once you have put the DVD in, and if you are logged into the desktop, the movie should automatically pop up to be played. If it does not, find the VLC Media Player and play it from there. There may be a shortcut on the desktop, or you can search for it via the search feature. The application will look like the image below.
