VGA was the original video standard for computers which means it’s been in use since the 1980s. Not many computers today ship with VGA outputs but plenty of external displays and video projectors still require VGA input. USB to VGA adapters can help to bridge this gap.
Example uses for USB to VGA adapters and converters:
Say you have a video projector with VGA input but a laptop with no VGA output. You can use a USB to VGA adapter to connect your laptop to the video projector (or an external monitor that accepts VGA input).
The Best USB to VGA adapters and converters:
This USB to VGA adapter works on either USB 2.0 and 3.0 ports on your computer. It also works on both Macs and PCs, provided to install the free USB to VGA driver software. The maximum resolution that this converter will handle is 1920 x 1200 resolution, slightly higher than 1080p HD video.
This USB to VGA output cable also functions as a mini hub, providing a replacement USB port for the port that you lose when it’s plugged in. In other words, you can both output VGA video and use a USB device (such as a keyboard) at the same time with a single port (it’s hidden in the picture shown, but the USB port is on the side directly opposite the VGA port). This is especially handy if you have a laptop with a limited number of USB ports. This connector works on both Macs and PCs.
This USB to VGA adapter works with both USB 2.0 and USB 3.0 ports. It does not work on Mac laptops or Microsoft Surfaces, but if you have a Windows-based PC laptop running Windows 7 or 8, this converter will work without needing to install a driver.
This is a simple USB to VGA adapter that also comes with an additional DVI to VGA plug, meaning you can “daisy chain” the two adapters together to output either DVI or VGA from a USB port. Note that it only supports Windows PCs and comes with special software that needs to be installed in order for it to work.
