5.0 TYPICAL USES The DVI-3221a VGA Converter / Scaler is capable of many types of signal conversion. Below are some common examples of tasks that are within the scope of their capability, depending upon which model is used.
6.0 CONTROLLING THE SCALER The Scaler is controlled via three buttons and status is indicated by OSD. • Menu Button: This Button displays the Menu Options via the On Screen Display on the display device connected to the output. 6.1 thru 6.7 detail the sub-menus. • + and - Buttons: These Buttons allow navigation within the Menu and adjustments of the parameters available. • XGA Reset: Simultaneously depressing the – and + buttons returns settings to factory defaults and sets the output to XGA.
Use the + and – Buttons to choose the desired PC or HDTV output resolution from the available selections in the sub-menu. 6.3 Operation Controls and Functions When this is selected, the following Picture Adjust sub-menu will appear: Contrast 047 Bright 102 Color 064 Red 128 Green 128 Blue Reset Exit 128 The adjustment range for Contrast, Brightness, Red, Green and Blue is 0-255 for each. The factory default preset values are listed to the right of the adjustment box pictured above.
Simultaneously pressing and holding the + and – Buttons will also return the unit to the factory default settings and the output to XGA@60Hz. Note: The Scaler has a “last setting memory”, so the current settings will be retained when the power is turned off and the unit will return to those settings when the power is turned back on. 7.0 TROUBLESHOOTING Other than checking for faulty cables, the only common problem would be choosing a wrong Output Setting.
