2 Port VGA Auto Switch
Switch between 2 VGA signals on a single display; features automatic, prioritized switching
Product ID: ST122VGAU
The ST122VGAU VGA Auto Switcher lets you share a display between two computers and prioritize your VGA signals. The VGA switch features a primary and secondary VGA input port, and automatically outputs the signal from the primary input. When the signal feed connected to the primary input port is cut, the switcher automatically defaults to the video signal on the secondary VGA input port.
Designed for maximum control and versatility, the VGA Auto switcher also offers manual control of connected signals with easy-to-use front panel buttons that allow you to toggle between video sources.
- Ideal for use with a laptop computer and a boardroom projector in meetings and presentations, backup safety control systems, and home A/V switching applications
- Perfect for digital signage applications in retail environments requiring more than one media player or PC to be connected
- Great for connecting/switching multiple sources in Test Bench Facilities, Data Centers, Help Desks and Video Broadcasting Facilities
The StarTech.com Advantage
- Auto-sensing technology detects the loss of a signal and automatically switches to the secondary source preventing loss of display
- Sharing a single display between two computers saves the cost and desk space of purchasing an additional display

Frequently Asked Questions
Before You Buy
This device outputs a VGA signal. 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.
|Target connection||First conversion||Second conversion (if required)|
|DVI-D||VGA to HDMI: https://www.startech.com/AV/Converters/Video/?filter_AVINPUT=VGA&filter_AVOUTPUT=HDMI.||HDMI to DVI-D: https://www.startech.com/AV/Converters/Video/?filter_AVINPUT=VGA&filter_AVOUTPUT=HDMI.|
|DVI-I||VGA to DVI-I: https://www.startech.com/Cables/Audio-Video/Video-Adapter/DVIVGA/.||N/A|
|DisplayPort||VGA to HDMI: https://www.startech.com/AV/Converters/Video/?filter_AVINPUT=VGA&filter_AVOUTPUT=HDMI.||HDMI to DisplayPort: https://www.startech.com/AV/Converters/Video/?filter_AVINPUT=HDMI&filter_AVOUTPUT=DisplayPort.|
Note: You might need to use more than one converter as part of your solution; however, you should try to use the least number of converters and cables to connect your source and destination. If you have the option to convert to multiple target video connections, choose the option that requires the fewest number of conversions.
DVI-I and DVI-D
When you convert from VGA to DVI, you need to know if you are converting to a DVI-I or a DVI-D connection. For more information about how to identify the type of connection that you need, refer to the following FAQ: https://www.startech.com/faq/video_signal_converters_dvi_interface.
You also need to know which form of DVI that you are using, because DVI-I supports both analog (VGA) and digital (HDMI) signals, while DVI-D only supports digital (HDMI) signals.
Note: Certain devices may have a DVI-I connection but only support DVI-D signaling. It is important to verify that your DVI-I device supports DVI-I signaling.
This device has a VGA input port. If you have a video source that uses another video connection, there are options available to convert the video signal or connection. These options will be outlined below for each video source connection.

You also need to know which form of DVI that you are using, because DVI-I supports both analog (VGA) and digital (HDMI) signals, while DVI-D only supports digital (HDMI) signals. Some DVI-I connections only support DVI-D signaling. In this case, you must use a DVI-D to VGA converter.
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.
