Frequently Asked Questions

Installation

Troubleshooting

When you troubleshoot issues with a USB 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 source

  • Video destination

  • USB video adapter

To test your setup components, try the following:

  • Use the video cables, video source, video destination, and USB video adapter in another setup to see if the problem is with the components or the setup.

  • Use a different video cable, video source, video destination, and USB video adapter 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 cables, video source, video destination, and USB video adapter, it is recommended that you do the following:

  • Check Device Manager under Display adapters, Universal Serial Bus controllers, or USB Display adapters. To do this, press the Windows key + R, type devmgmt.msc, and press Enter to open Device Manager.

  • If you do not see the USB video adapter in Device Manager, refer to the following FAQ: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#usb-cannot-detect-windows.

  • If the device is listed with an error, reinstall the drivers following the instructions on the website.

  • Check to see if your video card drivers are current. You can check what video card you have in Device Manager under Display adapters. It is recommended that you go directly to the video card manufacturer's website to check for the latest drivers.

  • Check to see if the monitor is being detected by Windows.

To check to see if Windows is detecting the monitor using a computer that is running a version of Windows XP, do the following:

  • Right-click on the desktop and click Properties.
  • Click the Settings tab.
  • If you see Drag the monitor icons to match the physical arrangement of your monitors, it means that Windows is detecting more than a single monitor. You can click the drop-down menu under Display to see which monitors are detected. This option is not available if Windows only detects a single monitor.

To check to see if Windows is detecting the monitor using a computer that is running a version of Windows Vista, Windows 7, or Windows 8, do the following:

  • Right-click on the desktop and click Screen Resolution.
  • You can click the drop-down menu under Display to see which monitors are detected.

If the display connected through your USB display adapter does not wake up after your computer has been in extended hibernation, it is likely that Windows has automatically turned off the USB Root hub to save power.

While the purpose of our USB Video Adapters are to add an additional video output to your laptop or desktop computer, these adapters still require some resources from your internal video card. On a small number of video cards, adding a USB Video Adapter can exceed the limit of available resources, causing one of the connected displays to turn off.

As a possible workaround for this issue, we recommend using a more powerful USB Video Adapter that has a higher amount of integrated RAM, such as our USB32VGAPRO (512MB), USB32DVIPRO (512MB), or USB32HDDVII (1GB).

Touchscreen Monitors

A mixture of touchscreen and non-touchscreen displays can cause a conflict with your internal video card. Because of this limitation, touchscreen functions may be disabled when the USB Video Adapter is connected, or the USB Video Adapter may not work at all. Contact the manufacturer of your system to confirm whether your specific model can support a secondary display or not.

All-in-One Computers

Many all-in-one computer systems limit the number of possible monitors to one. This is a limitation in how all-in-one computers are typically manufactured, so adding an external display may not be possible regardless of which USB video adapter is used. Contact the manufacturer of your system to confirm whether your specific model can support a secondary display or not.

When you use remote desktop software to access a computer with a USB video adapter, keep the following things in mind:

  • Not all remote desktop software supports multiple monitors.
  • Not all remote desktop software supports monitors that use USB video adapters.
  • If the primary monitor is a monitor that uses a USB video adapter, you might run into problems.  If you do, try to continue to log in as the display might come back once you log in.

In order for your mouse to move properly between your monitors you must rearrange your monitors in Windows to match the physical location of your monitors on your desk. To do so, complete the following based on your operating system:

  1. On your keyboard, press the Windows key + X and select Control Panel.
  2. Click Appearance and Personalization, then click Display.
  3. Click the Resolution or Adjust Resolution option from the left column, which will display your monitors as numbered icons.
  4. Click Identify to display the numbers on each connected monitor, showing how the operating system has assigned their positions.
  5. Click and drag the monitor icons to best match your physical setup.
  6. Click OK to apply the changes and close the window.

Windows 7 and Windows Vista

Before You Buy

You may have heard of USB video adapters, and have been wondering what they are, and whether or not they will work in your setup.

USB video adapters are devices that take one USB port and go to one or many video connections, such as VGA, DVI, HDMI or DisplayPort.  This is useful if you would like to add an additional display to your computer setup, but are out of video connections on your computer. 

USB video adapters allow you to mirror or duplicate your display, so the same windows are shown on all of your displays, or extend your desktop, so that you can have different windows on each display.

So what do you need to know before you purchase a USB video adapter?

  • USB video adapters require the computer to have a free USB port.
  • Check which video connections your display has, and select the appropriate USB video adapter.
  • Ensure that the USB video adapter is compatible with your operating system.
  • USB video adapters require your video card to be able to handle an additional display.  This is because USB video adapters work with your onboard or dedicated video card to drive additional displays.  For this reason you are advised to confirm this with your video card manufacturer. 
  • Consider what you will be doing on the additional display.  If you are looking to perform less graphically intensive activities like using Microsoft Office, email, or basic web surfing, you can use any USB video adapter.  If you are looking to perform more graphically intensive activities like high end photo or video editing, you want a USB video adapter with dedicated memory. 

There are a few other important things to note:

  • When using multiple USB video adapters on the same computer, they need to use the same chipset family.  For example, MCT/Trigger, DisplayLink or Fresco.  Note: How many adapters you can use depends on the SKU.
  • You may not be able to use a USB video adapter with an All-In-One computer.  These computers are almost always hardwired to only accept a single display.
  • You may not be able to use a USB video adapter with a touchscreen computer or display.  A mixture of touchscreen and non-touchscreen devices can conflict with the video card. 
  • You should not use a USB video adapter to play video games.  They are not designed for use with video games, and their performance with them is poor at best.

Arrived quickly, works as designed

By: 3displayman - 10-20-2014
My goal was to have 3 monitors connected to my PC, of which, the video card only supports 2. This device is simple to set up and with minimal effort, I had a third display. It makes my work a lot easier so I am happy with the product (as of a month or so when I ordered it).
