TROUBLESHOOTING

Display Image Appears Fuzzy / Poor Quality (Analog Signal Issue)

Possible Recovery:

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 ‘+’ and ‘-’ arrow buttons to highlight the “Graphics Mode”

option. Press the “Menu” button to access the “Graphics Mode” submenu. The “Horz Fine” and “Horz Coarse” options are only availabe to ANALOG

video sources.

If the configuration screen reads ANALOG for the Channel Type and the user is expecting a DIGITAL signal, then the display may not be

receiving a digital signal that it can understand. This 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.

Possible Recovery:

In some cases, poor image quality may be caused by a break in the connection. Check for potential breaks by looking for damage or frays to the

cable, particularly near connector heads. Also check connector pins to ensure that they are properly aligned to fit into the designated connector

jack. If the problem persists, try replacing the video cable.

Possible Recovery:

Some electronics and cellular devices generate electrical/radio interference. The problem may result from close proximity to such a device. Be

sure that all items that may cause interference are kept away from the display.

Possible Recovery:

Low signal level is a potential cause for poor image quality. If the previous processes have not resolved the issue, try connecting the display to a

video source that provides a clear picture to another display. This will rule out variables and narrow troubleshooting direction.

Possible Recovery:

Make sure that video cables are properly seated on the back of the display panel. A bad seating can have the RGB connectors misaligned. These

RGB options are only available for Analog video signals. In the event that these color adjustments have been changed and are out of balance -

Reset menu settings to default.

Display Image is Not Centered

If the main image is not centered on the display, access the “Graphics Mode” menu in the OSD. Using the ‘+’ and ‘-’ buttons adjust the ‘Vert’ and

‘Horz’ position until image is appropriately centered.

If the OSD is not positioned in a desired location, an independent menu for OSD options can be found within the “Advanced Options” menu.

Problems with Analog Signal Resolution at 1920x1200@60

Possible Recovery:

This issue is generally resolved by designating the correct signal format (digital or analog) under Channel Type in the Configurations OSD menu.

This communicates to the display the correct Extended Display Identification Data (EDID) information. The settings are passed on to the Graphics

Card and 1920x1200@60 reduced blankoing is produced by the graphics card.

Be sure that the EDID information is passed to the graphics card and that your graphics card recognizes the IDS Display as a “ZMicro display.”
