Auto Image
NOTE: Some screen savers inter-
fere with the operation of Auto 
Image. If you’re experiencing prob-
lems, try turning your screen saver 
off, then turning Auto Image off 
and back on.
The projector automatically adjusts tracking, signal synchroniza-
tion and vertical and horizontal position for most computers 
(Auto Image does not apply to video sources). If you want to 
adjust these features manually, you must turn off 
Auto Image first 
by highlighting Auto Image in the Image menu and clicking 
either mouse button to select “off”.
Auto Resize
Auto Resize
 automatically resizes the image by scaling it up or 
down. It only affects computer images that are not 1024x768, the 
projector ’s native resolution.
When 
Auto Resize is on, the projector makes the best fit of the 
image to the screen. If you turn 
Auto Resize off (by highlighting it 
in the Image menu and clicking either mouse button to select 
“off”), the image may be either cropped or too small for the 
screen.
Manual Sync
The projector adjusts signal synchronization automatically for 
most computers. But if the projected computer image looks fuzzy 
or streaked, try turning 
Auto Image off then back on again. If the 
image still looks bad, try adjusting the signal synchronization 
manually:
1Turn Auto Image off.
2Highlight Manual sync, then press either mouse button 
repeatedly until the image is sharp and free of streaks.
