Questions & Answers

No video signal is appearing on my display. How do I fix this?
Check that the device is not being used in reverse. The display does not support the resolution set within Display Settings. Adjust the resolution to be the exact resolution and refresh rate recommended by the display manufacturer.

Everything is hooked up but nothing is working. What should I do?
When you troubleshoot issues with a video adapter, 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 adapter Video source (such as a DVD player or computer) Video destination (such as a monitor or projector) To test your setup components, try the following: Use the cable, video adapter, 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 adapter, 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 adapter from your setup and test to make sure that the video source and video destination work together without the video adapter. 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, adapter, and destination all need to support the resolution that you are using.

Does this device support bidirectional conversion?
No, this device does not support bidirectional conversion. It is designed to operate in one direction only. Explanation This device converts signals from a specific input (source) to a specific output (destination) . It cannot reverse the signal path or function in the opposite direction. The supported direction of conversion is determined by the product’s design and is clearly indicated in the product title and technical specifications. Attempting to use the device in reverse is not supported and will not function.

What is the difference between a passive and active DisplayPort adapter?
Passive and active DisplayPort adapters are used to convert DisplayPort or Mini DisplayPort signals to other video formats such as HDMI, DVI, or VGA. The correct adapter type depends on whether the DisplayPort source supports DisplayPort Dual-Mode (DP++). Passive adapters rely on the source device to perform the conversion, while active adapters perform the conversion internally. Explanation: When connecting a DisplayPort or Mini DisplayPort source to a monitor that uses HDMI, DVI, or VGA, it is important to determine whether a passive or active adapter is required. Passive DisplayPort Adapters Passive adapters do not contain signal conversion hardware. Instead, they rely on the DisplayPort source device to output a compatible HDMI or DVI signal using DisplayPort Dual-Mode (DP++). Passive adapters can be used when: The DisplayPort source supports DP++ Converting from DisplayPort to HDMI Converting from DisplayPort to DVI Because passive adapters do not contain conversion circuitry, they are typically less expensive than active adapters. Many DP++ ports are identified by the DisplayPort Dual-Mode (DP++) logo. Refer to the device documentation to confirm DP++ support. Active DisplayPort Adapters Active adapters contain integrated conversion circuitry that converts the DisplayPort signal to another video format. Active adapters can be used when: The DisplayPort source does not support DP++ Converting from DisplayPort to VGA Connecting displays in environments that require active signal conversion Multi-monitor configurations where passive adapter limitations may apply Because active adapters perform the signal conversion internally, they generally provide broader compatibility but are typically more expensive than passive adapters. Multi-Monitor Considerations For multi-monitor installations, active adapters may be required depending on the capabilities of the graphics hardware. Some graphics cards have limits on the number of displays that can be driven through DP++ outputs simultaneously. In these situations, active adapters may be necessary to support the desired monitor configuration. Always verify the display limitations and adapter requirements specified by the graphics card manufacturer. Thunderbolt Compatibility Thunderbolt ports natively support DisplayPort technology and generally support DP++ functionality. However, multi-monitor configurations may still require active adapters depending on the system design and display setup. MST Hub Compatibility When using StarTech.com MST hubs: Passive adapters are generally recommended for HDMI and DVI displays. Active adapters are required when converting from DisplayPort to VGA. Microsoft Surface Dock Compatibility Microsoft recommends using active video adapters with certain Surface Dock models if display issues occur when using passive adapters. This recommendation applies to supported Surface Dock products but does not apply to the Surface Pro 3 Docking Station.

The top and bottom portion of the video signal is cut off on the HDMI Display. How do I fix this?
Using the On-Screen Display menu for the display, enter the Menu system and go into “Picture Mode” then “Aspect ratio” and change from “16:9” to “Just scan” or “1:1 pixel mapping.” The wording may vary depending on the manufacturer of the display.
