HDMI Over IP Extender - 1080p

To get the highest quality signal from your source to your display when you use an HDMI extender, do the following:

• Make sure that the HDMI versions of the source, extender, and destination are compatible. For example, if you require 3D support, make sure that all of the devices can support 3D over HDMI.

• Use the least amount of adapters, splitters, or converters as possible. Each device that you use in your setup creates additional points of potential failure and creates more steps for an HDCP key to hop through, which may cause issues with older displays. For more information on HDCP, refer to the following FAQ: http://www.startech.com/faq/video_signal_converters_HDCP.

• Use an HDMI extender that exceeds the requirements of the setup. For example, if you need to extend the signal 200 feet, it is best to use an extender capable of more than 200 feet.

• Make sure that all of the CAT 5/6 runs are as straight as possible, with the least amount of coiling.

• Make sure that all of the patches, wall jacks, and cables use the highest possible CAT specification, (for example, CAT 6), and were tested to conform to the standard.

• Use patches, wall jacks, and cables with the same pin configuration. For more information on T568A versus T568B wiring, refer to the following FAQ: http://www.startech.com/faq/network_cables_a_vs_b_pinout.

• Keep the cabling away from sources of high noise.

• Make sure that you use adequate electrical grounding in your setup.

Computers running macOS Catalina (10.15) may experience compatibility issues with products that use DisplayLink technology, such as USB Docking Stations and Video Adapters. Connecting to a DisplayLink-powered Product may cause the Display(s) to output a blank screen. If you experience this problem, follow these steps:

1. Update computer to the latest version of macOS 10.15
2. Permit Screen Recording by following these steps: macOS Catalina 10.15: Screen Recording permission (external link)
3. Enable the DisplayLink Kernel Extension by following these steps: macOS 10.13, 10.14 and 10.15: Video functionality not enabled (external link)
4. If the problem persists, try installing the DisplayLink Manager Application (external link). Be sure to run the application after installation and select “Launch automatically after logging-in” for it to start automatically every time you log-in.

1. The power adapter may not be connected at the correct unit or may not be connected at all.  Please check your product manual to see where your power adapter has to be positioned.
2. An adapter to another video signal may be connected to the Transmitter or Receiver unit.  Please avoid any converters for the initial setup.
3. The Cat 5 or 6 cable coming from the transmitter or receiver unit may be connected to a network switch.  Some of our video extenders will work in this configuration, but others will not. Please check your product manual to see if your model can be used connected to an IP network. For the initial setup, avoid connecting the Cat 5 or 6 cables to any network switch, hub, or router.
4. The category of Unshielded Twisted Pair (UTP) cables may not meet StarTech.com’s requirements. Ensure at least Cat 5, 5e, or six cables are used, and they have eight wires. Some Cat 5 cables only have four wires. If using Cat 6 cables, be aware they have more twists per foot, so you may have to use shorter cable lengths if using Cat 6 cabling between your video extenders.
5. Bundling up the UTP cabling connected to the extenders can cause crosstalk, which will prevent the video signal from showing on the display.  Unwrapping the cable should resolve this issue.

1. Please check to see if your model has an adjustable Gain dial on the remote unit.
2. If it does, use it to adjust the color until it is acceptable.
3. Replace the VGA cable with a higher quality cable like StarTech.com’s MXT101MMHQ.

When you troubleshoot issues with a video extender, 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:

• Video and Ethernet cables

• Video extender

• Video source (such as a DVD player or computer)

• Video destination (such as a monitor or projector)

Note: When you are testing 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 the cable, video extender, video source, and video destination in another setup to see if the problem is with the components or the setup.

• Use a different cable, video extender, 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 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:

• Remove the video extender from your setup and test to make sure that the video source and video destination work together without the video 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.

If the IP extender detects that it does not have the necessary bandwidth to function, it may disconnect from the network.  It is recommended that you use the IP extender with a switch or router with no other networking devices connected to it.

If the IP extender outputs video at 1920x1080, it can use up to 136Mbps. If the IP extender outputs video at 1920x1080 and remote USB devices are connected it, the IP extender can use up to 275Mbps.

Make sure that your network can support the bandwidth required by the IP extender.
