However the quality means it's probably not worthwhile. Projecting a computer-generated digital image through a digital-to-analog converter onto a low-def, big screen TV is a recipe for yuck.
Note that cables that have the appropriate ends will NOT work, you need to convert the HDMI digital signal to analog. Also, the standard computer VGA connection is analog. However, if you happen to have a DVI connection on your TV a simple cable will suffice.
