Adjusting the projected image from
the computer
The unit selects the most suitable resolutions as shown in the “Timing Chart” below according to the incoming signals from the RGB/YCbCr
connector. However, you may need manual adjustment depending on the computer. If you have any vertical banding, noise, dot interference,
or crosstalk on the projected picture, adjust the clock frequency with “PICTURE ADJ” then the clock phase with “FINE PICTURE” (see page
24). You can also adjust the horizontal and vertical position of the image (see page 24).
When adjusting manually, you can choose to project the image at the original size of the incoming signal resolution (see page 27). (Normally,
the image is enlarged or reduced to the most suitable size automatically.)
Timing Chart
The resolution of the unit is 1024 × 768. Other resolution images (e.g. 1280 × 1024) are compressed into 1024 × 768. In such a case, projected letters
and lines might appear unevenly.
