Product ID: ST122HDMI2
The ST122HDMI2 2-Port High Speed HDMI® Splitter and Signal Amplifier lets you share a single HDMI source signal with audio between two HDMI or DVI (using HDMI to DVI adapter - see Accessories) enabled displays simultaneously.
Supporting True HD 1080p video resolutions, the HDMI splitter acts as a distribution amplifier that enables you to situate your HDMI-capable displays up to 50ft (15m) away from the splitter, and features 3.5mm audio connections, giving you the option of sending your accompanying audio signal through the HDMI cable, or through a separate channel.
The HDMI splitter is easy to install and use with no software or configuration required, for a completely plug-and-play setup that can be used with HDMI output devices such as Blu-ray players or desktop/laptop computers.
This product is TAA compliant and backed by a Startech.com 3-year warranty with free lifetime technical support.

When you troubleshoot issues with a video splitter, 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 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 splitter, you should use an HDMI source when you test the components.
To test your setup components, try the following:
Use the cable, video splitter, 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 splitter, 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 splitter from your setup and test to make sure that the video source and video destination work together without the video splitter.
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, splitter, and destination all need to support the resolution that you are using.
Video splitters take the output for monitor port 1 and mirror it to the remaining outputs. By default, the first output port is the master port that is mirrored to each additional monitor. Make sure that you use the first output port when you use the video splitter. The master port is labeled on the splitter boxes from StarTech.com. On the splitter cables from StarTech.com, the master port is the top port.
If you are having issues with a splitter interpreting the incorrect port as the master port, try the following:
Unplug all of the video connections.
If the splitter is powered, power cycle the splitter.
Plug in all of the video connections again.
Make sure that the first video connection plugged in is the one that you want to be the master port.
You might encounter resolution issues when you use a video splitter. This can occur because the information and resolution on one display are being copied and sent to each of the additional displays. You should make sure that all of the displays that you are using can support the output resolution.

This device outputs HDMI video signals. If you have a display or video destination that uses another type of video connection, there are ways that you can convert the video signal or connection. These options are outlined below and organized by the target connection.
When you consider whether to convert an HDMI video signal to another connection type, it is important to know if the media that is being converted from the HDMI video connection is protected by High-bandwidth Digital Content Protection (HDCP). If the media is protected by HDCP, you cannot convert to analog video connections because they do not support HDCP. You may experience this issue when you use devices like Blu-ray players, DVD players, and certain gaming consoles.
