ADJUSTING THE DISPLAY
FACTORY PRESETS, AUTO-SYNC, AND USER SETTINGS
Factory presets: For optimal display quality, set your video card to the DTF-521’s native resolution of
1024 x 768 pixels. See page 49 for signal specifications.
Auto-sync: The DTF-521 attempts to automatically synchronize to the incoming signal. Auto-sync will
function when the horizontal frequency is between 30 to 57 kHz and the vertical frequency is between
45 to 70 Hz for XGA mode, or 45 to 75 Hz for other modes. If the DTF-521 does not automatically
synchronize with the incoming signal, you can use the On Screen Display (OSD) RESET AUTO ADJUST
option to initiate display synchronization. Further screen display adjustments can be manually made
using the OSD controls.
User settings: When you manually set the display using the OSD function, the settings are stored
within the DTF-521 for use the next time the unit receives a similar signal. This is applicable to all
display modes.
ON SCREEN DISPLAY (OSD) SETTINGS
The OSD function enables you to adjust and optimize a variety of display settings at the touch of a
button. The OSD controls are located on the upper left edge of the unit.
The basic process for working with the OSD is as follows:
• Press the MENU button to open the OSD main menu.
• Use the + or – buttons to select an option. When the option you want to adjust is highlighted,
press the ENTER button. The current settings and adjustment sub-menu for that option will appear.
• Use the + or – buttons to adjust the option settings.
• After making your changes, press the ENTER button to save. To exit, press the MENU button.
Note: All settings are automatically saved when the OSD menu closes. If you make changes to the display
appearance and cannot return to the original settings, use the
RESET RECALL option to return the DTF-521 to
its original factory defaults.
