Enjoy hassle-free operation with three switching modes:
An IR remote control is included in the box, enabling you to select your desired input source remotely. The RS-232 serial control interface ensures easy remote operation with serial control enabled devices.
The switch also saves time during setup with EDID emulation, which ensures that all of your display settings, such as native resolution and refresh rate, are communicated between your display and video source devices. EDID emulation maximizes compatibility with your 4K display, ensuring a convenient plug-and-play installation and the sharpest image quality.
The VS421HD4KA is TAA compliant and backed by a 2-year StarTech.com warranty with free lifetime technical support.

Connect an HDMI®-enabled output device to a DVI-D display, or a DVI-D output device to an HDMI-capable display
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 switch, you should use an HDMI source when you test the components.
To test your setup components, try the following:
Use the cable, video switch, 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 switch, 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 switch from your setup and test to make sure that the video source and video destination work together without the video switch.
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, switch, and destination all need to support the resolution that you are using.
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.
