Does it do anything? Yes, 1024 x 768 @ 60 Hz. Period. And it needs a 5 BNC connector. And it's heavy. Controls are minimal (brightness / contrast), documentation is hard to find, picture quality isn't that great. It has only one thing going for it: size. The 1k resolution on a big screen is highly legible. All in all: not recommended, unless it can be had for free. Should make the goldfish a nice home.
