Display image Has Vertical Bars
If the main image begins to display vertical bars, adjust the “Horz Coarse”. From the Main
Menu, use the Up and Down buttons to highlight the “Graphics Mode” option. Press the
“Menu” button to access the “Graphics Mode” submenu. Use the Left and Right buttons
to adjust the screen until the number of bars is reduced. Continue adjusting one step at a
time until the bars are no longer visible.
Display image appears Fuzzy
If the main image begins to appear fuzzy or “noisy”, adjust the “Horz Fine” until it is
reduced. The “Horz Fine” option adjusts the phase of the video sampling clock. To
access the “Horz Fine” submenu from the Main Menu, use the Up and Down buttons to
highlight the “Graphics Mode” option. Press the “Menu” button to access the “Graphics
Mode” submenu.
If the configuration screen reads ANALOG for the Channel Type and the user is
expecting a DIGITAL signal then the display is not receiving a pure digital signal.
The problem may result from an incompatibility in the graphics card. The source
graphics card may not be certified to full DVI-I specification and may be defaulting
to an analog signal. One option is to change the configuration in the graphics card to
transmit only a DVI-D signal. A second option is to use a DVI-D cable to connect the
host system to the display.
