A USB video card is often both a graphics card and an adapter. With a USB video card you connect the USB 3.0 port of your computer or other device to 1 or more monitors. This way you can connect additional monitors, LCD screens or projector screens (up to 6 pieces).
An additional network interface is also available with various types. The adapter can duplicate (mirror) or expand the screen and, depending on the type of USB video card, it supports various resolutions. Read more about all options such as connection options of USB video cards that we have listed.

USB Video Card, what can you do with them?
Graphic work such as video editing requires multiple screens. But also other applications, private or at work, often benefit from more and flexible screen space. Not everyone knows that a USB video card can control not one, but 6 additional monitors.
In addition, with a USB video card you not only expand your computer with a monitor port, but in some cases also with a Gigabit LAN interface and an extra USB 3.0 interface. For various models, you can also connect an HDMI monitor and a VGA monitor to the adapter.
USB 3 Connection
USB video cards come with a USB 3.0 connection. The big difference between USB 2 and USB 3 is the speed of data transfer with a USB video card. USB 3 is ten times (10X) faster than USB 2. The high speed of USB 3 can only be achieved if your PC or laptop also has a USB 3 port. You can easily check this. The USB 2 port and plug are gray or black on the inside and the USB 3 port and plug are blue on the inside.
Fortunately, it is no problem to mix USB 2 and 3 devices. You can then transfer data at the speed of USB 2. To take advantage of the high data speed of USB 3, it is necessary that both your USB video card and your computer are equipped with a USB 3 connection. There is also USB 3.1 (also known as SuperSpeed +). The transfer rate has doubled from 5 gigabit / s to 10 gigabit / s. USB 3.1 uses the same cables as USB 3.0, at the same time a new plug has been added.
HDMI, DisplayPort and VGA
Our USB video cards support multiple standards. DisplayPort is mainly used for image transfer, but can also transfer sound between, for example, computers and monitors. A major competitor of DisplayPort is High-Definition Multimedia Interface (HDMI), a connection for audio and video signals in uncompressed digital form. That way you eliminate analog conversion. Unlike the predecessor Digital Visual Interface (DVI), HDMI also supports sound. VGA or Video Graphics Array is a standard for analog display of images on a computer monitor.
However, new standards (such as DVI, HDMI and DisplayPort) are increasingly being used. In addition to being the standard for high-definition multimedia equipment, HDMI may also become the new digital standard for computer monitors.
System requirements – USB Video Card
It is important that you check the relevant product page for which system or systems your USB video card is suitable. There are specific requirements for a USB video card for both Windows and MacOS, but also for other operating systems. This page also indicates the resolution, as well as the available numbers and types of ports to which the monitors can be connected.
