Why does one of my connected displays turn off when my USB video adapter is connected?
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).

Will my touchscreen / all-in-one computer work with a USB Video Adapter?
Touchscreen Monitors A mixture of touchscreen and non-touchscreen displays can cause a conflict with your internal video card.

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.

What is the difference between mirroring, spanning, and extending monitors?
Mirroring monitors means that you see the same thing on multiple monitors. Spanning monitors means that your computer interprets all of the monitors that are spanning as one giant monitor. You can see different things on each monitor, and your desktop, taskbar, Start menu, and background are stretched across the monitors. Extending monitors means that your computer interprets the monitors that you are extending as separate devices. You can see different things on each monitor, and your desktop background is displayed on each monitor. In general, video splitters can only be used to mirror monitors. If you want to extend your desktop across monitors, you need to make a separate video connection for each monitor that you are attaching. If you want to attach more monitors than your computer has video ports for, you can read about USB Video Adapters here: www.startech.com/AV/USB-Video-Adapters/ .
