Extron electronic D/2 DA4 DVI Operation, Troubleshooting, Specifications, FCC Class A Notice

Operation

Operation

After the D/2 DA4 DVI and its connected devices are powered up, the system is fully operational. If any problems are encountered, verify that the cables are routed and connected properly, and that all display devices have identical resolutions and refresh rates.

The direct digital video output is tailored for a specific monitor resolution and refresh rate. Ensure that all display devices have identical resolutions and refresh rates, otherwise images may be distorted or missing.

Ensure that the computer and primary monitor are connected to the D/2 DA4 DVI, and the D/2 DA4 DVI and monitor have power applied, before applying power to the computer. If the other devices are not turned on before the computer is, the image will not appear.

Troubleshooting

DVI/DFP signals run at a very high frequency and are especially susceptible to bad video connections, too many adapters, or too long cables. To avoid the loss of an image or image jitter, follow these guidelines:

•Do not exceed 16.4 feet (5 meters) on the output of the DA.

•Use only cable designed for DVI signals.

•Limit or avoid the use of adapters.

•Use only approved DVI/DFP connectors.
