I purchased this for use in a dual monitor configuration to replace a broken graphics card connection on my workstation. After looking for a driver for an hour (cdrom is pretty much useless if your computer is over 10 years old) I noticed that the URL for the driver is mentioned in the Amazon product description. I installed the driver and after it didn't work I ran the utility that installed with the driver. He told me I can't use the adapter on my computer. I ended up buying a graphics card instead of this crappy machine.
