These products are the USB2VGA2 USB 2.0 to VGA Display Adapter and the USB2DVI USB 2.0 to DVI Display Adapter, priced at around $117 and $180 respectively.

The StarTech.com USB2VGA2 USB 2.0 to VGA Display Adapter and the USB2DVI USB 2.0 to DVI Display Adapter both connect to a single USB 2.0 port on a computer, offering support for up to five separate monitors (requires one adapter per display). The USB2VGA2 works with VGA display resolutions of up to 1600 x 1200 (32-bit), and up to 1920×1600 at 16-bit color quality, while the other one does DVI display resolutions up to 1600×1200 (standard) (@32 bits) and 1680×1050 (wide) (@ 32 bits).
