For most cable solutions, you will use the appropriate HDMI, VGA, or adapter cable to connect your computing device to the projector/display, and then select the matching input. You will connect a USB cable for your interactive controls. You will see a number of different cables and setups across our district. This quick guide should help you identify and properly connect devices.
Common Cables
| HDMI |
Commonly used to connect a laptop, tablet, or desktop to a projector/display. This cable carries both audio and video to the display device. |
| Display Port to HDMI |
Commonly used to connect a laptop, tablet, or desktop to a projector/display. This cable carries both audio and video to the display device. Most projectors and displays do not have a display port input. Most Dell desktops have display port video out. Therefore an adapter cable is needed. |
| HDMI to VGA |
Commonly used to connect a newer laptop with only HDMI out to an older projector with only VGA in. This is a very common setup for cart based projectors across our district. If you have a single VGA connection, you will have to make sure that your projector is set up with an “In Line” connection. This type of connection allows you to have your computer or mobile device and your document camera both connected to the single VGA port on the rear of your projector. |
USB Cables for Interactive Controls
USB cables are used to connect your computing device to a peripheral device for interactive control. If you are using an Epson Brightlink interactive projector, Boxlight display, EBeam, SMART board, etc. you will need a USB for interactive control.
In most cases, this USB cable has been installed to a wall plate. The ‘A’ end of the cable will plug into any available USB port on your PC. The other end of the cable, the ‘B’ end, will plug into a wall plate.
