I'm giving this product 5 stars because at the end of the day, it mostly does what I need it to. I'm not going to take away any stars because I didn't understand the listing exactly.I purchased this in the hopes of splitting a video signal and having it go to 2 monitors and a TV simultaneously. The video card we have has an HDMI and Displayport output. Currently one monitor is on the DVI and one is on Displayport, so I figured we could split the DVI. When I first hooked it up, neither the monitor or TV showed up at all and I assumed it was broken. I disconnected the HDMI part and the DVI showed up, which is fine, and likewise when I disconnect the DVI, the HDMI shows up. I don't find this to be a big issue because we have 3 displays total, so all this means is all 3 can't broadcast at once, but I can at least display one monitor and the TV or both monitors at the same time.I'm assuming the issue is due to the TV and monitors having totally different resolutions and the product not being able to do both. I believe if I was broadcasting to the same resolution it would be fine, but this works for us

This is a horrible product for what its designed to do.My first complaint is that the splitter part does not actually split into two separate DVI cables, instead it goes from the DVI-male end to a block of 2 DVI-female ends making it very bulky and heavy at the end. Also since the DVI-female ends are in a block construction they are not wired separately like a true DVI y-splitter.With that being said, the only thing this cable did was educate me in the types of splitters that exist: Y-splitters and Block-splitters. The reason I didn't know about block splitters this is the first company i've seen make the stupid things.Since block-splitters are not wired into separate cables they do not work if one of the female ends is unplugged. Also the PC doesn't recognized the block connection after a reboot even both female ends are plugged in--you will have to unplug and replug this thing in every reboot your computer makes if you want to display the picture from your video card. Finally block-splitters DO NOT extend display.All in All, This product will:Not extend displayNot mirror display if one display is turned offNot display after reboot unless it unplugged and plugged back inBuy a different cable

Worked perfect for about a month or so. Then one of the monitors started having problems with pixelation, or pixels that were not displaying properly. Of course, many things could cause this, but removing this splitter cleared it up. We were able to reconfigure our cables without the need for a splitter, so we don't use it anymore.Before I wrote this review, however, I tested the splitter on a different computer and monitor. I tested both outputs and did not have a problem.So, because I cannot consistently reproduce the problem, and thus can say with 100% certainty that this splitter is the problem, I still gave it 4 stars. I'm keeping with my cables in case I need it again.O, this is a DVI-D splitter, so keep that in mind. It may not work with some DVI-I applications. For example, you cannot use a VGA adapter with it.
