8Installing the DT770
Removing the Connection Panel’s Protective Cover
When you initially receive your DT770, the connection panel is inaccessible because of a
protective cover.
1. Place the DT770 facedown on a flat surface.
2. Loosen the captive screws in the protective cover with the supplied screwdriver.
3. Pull the cover away from the connection panel.
4. Put the cover somewhere safe. You may wish to reattach it after you have connected the
DT770’s cables.
Connecting the DT770
Complete the following procedure to connect the DT770 to your computer.
NOTE: For best results, use a computer with a video card that supports SXGA resolution
(1280 × 1024), and set the refresh rate to 60 Hz or 75 Hz. If you use a video card that supports
lower resolutions only, this may affect image quality. Don’t set the resolution of the DT770 to
greater than 1280 × 1024 (SXGA).
1. If you haven’t already done so, shut down your computer.

To remove the protective cover

CAUTION Place the DT770 down slowly and carefully to ensure you don’t damage the
buttons.
Don’t place the DT770 on a surface that will mark, scratch or damage the
screen or its optical components.
