6 ft DVI-D Dual Link Monitor Extension Cable - M/F

Questions & Answers

Everything is hooked up but nothing is working. What should I do?
When you troubleshoot issues with a DVI cable, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue: DVI cable Video source Video destination To test your setup components, try the following: Use the DVI cable, video source, and video destination in another setup to see if the problem is with the components or the setup. Use a different DVI cable, 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. When you test the video cables, video source, and video destination, it is recommended that you do the following: Make sure that you are using the correct type of DVI cable. For more information about DVI cables, see the following FAQ: http://www.startech.com/faq/video_signal_converters_dvi_interface . Verify that the source resolution matches the video source destination capabilities. For example, if the destination or DVI cable is only capable of 1920 x 1080, then the source cannot output 2560 x 1600, as that exceeds the capabilities of the destination or DVI cable. Test your setup components using a lower resolution or a lower refresh rate, for example, 1024 x 768. Note: Single Link DVI cables are only capable of resolutions up to 1920 x 1080. In order to obtain a resolution of 2560 x 1600, you will need to use a Dual Link DVI cable. For more information, see the FAQ link listed above.

When should I use a longer video cable instead of a video extender?
Use a longer video cable whenever possible; use a video extender only when the required distance exceeds the reliable limits of standard or active cables. Explanation: Direct cabling is the preferred method for video connections because it maintains signal integrity and reduces complexity. Standard maximum cable lengths for common video signals are: Video standard Maximum length DisplayPort 50 ft. (15.2m) HDMI 50 ft. (15.2m) DVI 50 ft. (15.2m) VGA 200 ft. (71m) Active cables can extend these distances by incorporating built-in signal amplification and are designed to exceed standard length limits while maintaining specified performance. Video extenders are used when cable length requirements exceed what passive or active cables can reliably support. Extenders transmit the signal over longer distances by boosting and then restoring it, while maintaining the same video standard from input to output.

How can I identify which DVI connector type I have or need?
You can identify the DVI connector type by the pin configuration and determine compatibility based on whether the connection supports analog, digital, or both signal types. Explanation: DVI (Digital Visual Interface) connectors are defined by their pin layout and supported signal type. The main DVI connector types are: DVI-A (17 pin) . Analog signal only DVI-D Single Link (19 pin) . Digital signal only DVI-D Dual Link (25 pin) . Digital signal only, higher bandwidth DVI-I Single Link (23 pin) . Supports both analog and digital signals DVI-I Dual Link (29 pin) . Supports both analog and digital signals, higher bandwidth DVI-A is used for analog signals (similar to VGA), while DVI-D is used for digital signals (similar to HDMI). DVI-I connectors can carry both analog and digital signals, but actual support depends on the device’s specifications. Single Link and Dual Link indicate bandwidth capacity, which affects maximum supported resolution. Typical limits are up to 1920 × 1080 @ 60 Hz for Single Link and up to 2560 × 1600 @ 60 Hz for Dual Link. However, actual resolution support depends on the capabilities of the connected devices, not just the connector type. To ensure compatibility, verify both the connector type and the signal support in the specifications of the source and display devices.
