Garmin 720C User Manual

The projector can be installed for three different viewing setups:
front projection, ceiling mounting, or rear projection onto a 
semi-transparent screen.

To project from overhead, you’ll need to select 

Ceiling

 in the 

projector’s Advanced menu. To project from the rear, select 

Rear 

Proj

. See page 46 for more information.

If you’re ceiling-mounting the projector and you place it above screen 
level, you’ll have to tilt it down to position the image on-screen. This 
causes the image to lose its rectangular shape. You can then correct the 
distortion by using the 

Keystone

 or 

Auto Keystone

 function in the 

projector’s menu system (see page 45).

If you place the projector’s lens so it’s level with the top of the screen, 
the image will be rectangular and you won’t have to adjust it. If you 
place the lens lower than the top of the screen, you’ll have to tilt the 
projector upward if you want to fill the whole screen with the image.

You can connect the projector to any IBM

®

 -compatible PC. This 

section includes instructions for the following:

■

Connecting the computer cable 

■

Connecting the mouse cable (if you want to use the remote 
control as a mouse)

■

Connecting an optional audio cable (if you’ll be projecting 
with audio)

When you connect the projector to a desktop computer, you cannot 
view your display on the computer monitor.

Follow the steps in each section for the cables you need to connect. 
Before beginning, turn off the projector and computer if they are on.
