Image Output Adjustment; Focus; Keystone - Dr. J HI-04 Quick Start & Troubleshooting Manual

4. Image Output Adjustment

4.1 Focus

The Focus adjustment wheel can be turned left and right to
sharpen or blur the image, depending on the distance of
the projector from the screen or wall.
Turn the wheel left or right until the image reaches the desi-
red sharpness.

4.2 Keystone

The Keystone adjustment wheel can be turned left and right
to adjust the shape of the projected image. It should only
be used if an image is not being projected from straight on
and appears distorted.
The Keystone adjustment fixes skewed image output, ma-
king it rectangular.
NOTE: The Dr. J HI-04 Mini Home Projector only has a
keystone adjustment of +/- 15 degrees, it can only fix sli-
ghtly skewed image outputs.
