To connect a computer to the projector, either plug the HDMI cord at the front of the room into your computer or connect wirelessly to the Apple TV.
The LGI A/V control panel is located in the front right of the room. If it is dark, tap it to wake it up.
Ensure the power is on to both the audio and the projector by tapping the "Audio" and "Projector" buttons in the upper right corner of the screen. If there is a blue line under the power button, it is on.
If the projector is not on but there is a blue line under the power button, turn it off and wait for the screen to go all the way up. After the screen is up, tap the "Projector" button to turn it back on.
Next, select the source. If you are plugged into the HDMI cord, select the HDMI option under "Stage Source." Do not select the option under "Rack Source." as this source is in the cabinet at the back of the LGI. If you are using the Apple TV, choose the Apple logo under "Rack Source."
For audio, the wireless handheld mic is the first one and is labeled "HH Wls." The volume labeled "Media" is audio from the source displayed on the projector screen. If you want audio from either, ensure the channel is not muted and the audio level is appropriate. If you do not see the desired source, you may have to swipe left or right in the "Audio Control" section.
The projector may take up to a minute to turn on and display your screen. If it is still not showing, check your computer's display settings and ensure they are correct. Refer to the articles below for instructions:
