Screen Sharing with the BenQ InstaShow
If you want to share the content from your mobile device to a larger display so that multiple people in the room can see it, the BenQ InstaShow is a good solution. Here is how to use it.
Determine Compatibility
Begin by verifying that your source laptop has a USB-C jack. 
Proceed after confirming that your conference room's Audio Video equipment includes a BenQ InstaShow.
If it is a conference room, the BenQ dongles will often be placed in a bin on the conference table.
Example... NGM 120, NGM 302, JLB AAO 160, TWC 110A
Prepare the Display
Press power button on wireless remote (or TV’s side panel) to turn display's power on.
Press Source button: Set to HDMI 1, or whichever HDMI setting that shows this image:
Connect the BenQ dongle to the laptop
- Locate the BenQ dongle, from the table-top bin,
- Insert it into the laptop’s USB-C jack. When the ring turns from Red to Green, it is ready to use. Please be patient.
- When the colored ring turns green, press the button. Within a few of seconds, the ring will turn blue, and the laptop image will appear on the TV.
- If the ring does not turn blue within 10 seconds after a single button press, some laptops (i.e., HP) may require this step: pressing and holding the button until the ring turns blue.
When done, Press power button on remote or TV’s side panel to turn TV OFF. Return BenQ dongle to bin.
