Product ID: ST124HD20
This 4K HDMI splitter lets you connect your HDMI video source to four HDMI displays, with support for Ultra HD resolutions and HDR (High Dynamic Range) as well as 7.1 surround sound audio.
Unlike many 4K splitters that only support a 30Hz refresh rate, this splitter works with 4K HDMI 2.0 displays with output resolutions of up to 3840 x 2160p at 60Hz.
Not all 4K splitters are created equal. While some HDMI 1.4 splitters can achieve 4K resolutions, they'll only work at a 30Hz refresh rate. Other HDMI 1.4 splitters are marketed as 4K at 60Hz, but their color data is reduced to a lower 4:2:0 chroma subsampling. This drastically reduces color quality in order to achieve 4K at 60Hz resolution, even with limited HDMI 1.4 bitrate capabilities.
This 4K 60Hz HDMI splitter offers full support for your HDMI 2.0 equipment, including true 4K resolution at 60Hz. For smoother video and color transitions, the splitter offers 4:4:4 chroma subsampling, meaning every pixel gets its own unique color. Support for HDMI 2.0 devices means this splitter can transmit bandwidth up to 18Gbps, making it the ideal solution for high-resolution tasks requiring the highest color detail.
The splitter supports HDCP 2.2 and is backward compatible with 4K 30Hz and 1080p displays. This ensures that it will work with lower resolution displays such as TVs or projectors around your site or in your digital signage application.
For hassle-free setup, the 4K HDMI splitter offers easy plug-and-play installation with no additional software or drivers required. The splitter passes EDID between your video source and the display attached to port 1, ensuring native settings such as resolution and refresh rate are configured automatically.
The ST124HD20 is backed by a 2-year StarTech.com warranty and free lifetime technical support.

Live Chat (opens in new window)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 cables
Video splitter
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.
HDCP
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.

HDMI 2.0 offers some new features that were not available with the HDMI 1.4 standard, including the following:
Although HDMI 2.0 is backwards compatible with older HDMI standards, newer HDMI devices need to support HDCP 2.2 in order to display new content. If you use an HDMI device that only supports HDCP 2.0, an error will be displayed when you try to display content that has HDCP 2.2.
