USB DVI over Cat 5e / Cat 6 KVM Console Extender w/ 1920x1200 Uncompressed Video - 330ft (100m)

There are some quick tests that you can complete to rule out potential issues. You can test to make sure that the following components are working correctly and are not the source of the issue:

• Video and Ethernet cables
• Mouse and keyboard
• Video source (such as a DVR or computer)
• Video destination (such as a monitor or projector)

Note: When you test setup components, you should avoid using video adapters. For example, if you are converting a VGA source to HDMI for use with an HDMI extender, you should use an HDMI source when you test the components.

To test your setup components, try the following:

• Use a different cable, mouse, keyboard, video source, and video destination in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.
• Use the cable, mouse, keyboard, video extender, video source, and video destination in another setup to see if the problem is with the components or the setup.

When you test your cables, it is recommended that you do the following:

• Test each cable individually.
• Use short cables when you are testing.

When you test the video source and video destination, it is recommended that you do the following:

• Test to make sure that the video source and video destination work together without using the KVM extender.
• Test to make sure that the video source and video destination work together at the resolution that you want to use.

Note: In order for your setup to work properly, the video source, extender, and destination all need to support the resolution that you are using.

Digital Visual Interface (DVI) is a video display interface that can contain different types of signaling, based on the application. DVI cables and ports are created using different connector types to identify what application they are intended to be used in. The connector types are identified by the number of pins on the DVI connector. DVI comes in the following five different connector types: 

• DVI-A (17 pin).
• DVI-D Single Link (19 pin).
• DVI-D Dual Link (25 pin).
• DVI-I Single Link (23 pin).
• DVI-I Dual Link (29 pin).

Single and Dual link DVI indicate the maximum resolution capabilities of the video source or video destination. The maximum resolutions are Single Link (1920 x 1080 @ 60Hz) and Dual Link (2560 x 1600 @ 60Hz).

Note: The maximum resolution of your video source and video destination are ultimately determined by the technical specifications of the devices. The connector type is not a definitive indicator of the maximum resolution.

DVI-A carries only analog (for example, VGA) with no digital component. DVI-D carries only digital video (for example, HDMI) with no analog component. DVI-I combines DVI-A and DVI-D connections to include both analog and digital components. A DVI-I port may be on either your video source or display, but whether or not a display carries either or both analog and digital sources depends on the technical specifications of your device.

This device has a DVI-D connector and is only compatible with digital DVI video signaling.  For more information about the different DVI connectors, refer to the following FAQ: https://www.startech.com/faq/video_signal_converters_dvi_interface.
