Customer Reviews

WARNING: Very Specific System Requirements
This is a solid cable, and as others have commented, it does split the image. However, it has some technical requirements that the company seems to have no interest in sharing:

Issue 1: You MUST have a dual-link DVI port on your computer. Many graphics cards that have two ports will have both a single-link DVI port, and a dual-link DVI port (like some for the MacPro). If you do not have a Dual-link port, your computer will not put out enough juice to split the signal.

Issue 2: Mac OS X uses an auto-detect to determine what monitor is attached and what resolution signal to send. It appears as though the cable has a primary side and a secondary side, so that only one monitor talks to the computer. OSX correctly identified 1920x1080 for my HDTV, but would not let me scale the output down to the 1680x1050 required of my monitor. (My computer monitor never accepted the signal from either output, even when it was the only thing plugged into it.)

All told, if you are trying to rig up a cheap man's DVI switch between two different devices (like a monitor and a TV) pay the money for a switch because this cable is built for one purpose only: splitting a single signal to two similar displays.

Does what it's supposed to do
It splits the signal as it's designed to, you can't complain there. You need your devices to be able to use it though, which can be an issue.

Not that simple.
Splitting a video signal is not that simple, your computers video card must support multiple displays (and if it does it prabobly alredy has 2 or more connections). if your video card does not support multiple displays this connector will definitlly not work. I found out the hard way.
