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.
