USB 2.0 VGA from DealExtreme

Reading time: 1 – 2 minutes

Several months ago I bought a video graphics adapter for USB 2.0 port. It’s compatible with Linux, Mac and Windows but for a while I’ve only used it with Windows where it works as a extended screen for my HDMI main display. It works very good with 1920×1080 pixels resolution and it can play videos fast enough using a standalone video player or HTML5 video streaming from the internet.

The chipset used by this product is DISPLAYLINK DL-165 with DVI, HDMI and VGA adapters. It is powered by USB port with 5V DC and 450mA about 2,25W of consumption; but after installing the display driver I lost 2GB of RAM, which in my case it isn’t a problem but sometimes it could be a handicap.

The official product page is here where you can find brochure in PDF and other useful information.

If you are looking for a powerful product for your SOHO network this is the solution as I like to say ‘this is one of the best communications servers’. It will be very difficult to find some feature or functionality that you can not get from this product. The product is robust and stable with the flexibility of RouterOS.
