... it only allows for cloning. The problem is in the terminology - "splitter" could be taken to mean "it splits one port into two ports with identical signals" or could also be taken to mean "it splits one port into two ports with separate signals".
The listing should specify whether it allows for extending displays (takes the two sets of digital connections of one DVI port and splits them into two ports) or only allows for cloning (just taking one of the two digital connections in the DVI port and wiring that up to both of the ports). While this is the Windows terminology, and DVI is OS independent, it would save a whole lot of confusion and disappointment.
I was told I can plug this to my computer and output to two monitors with ease. I did it, however only one picked up, when I unplugged one the other will come up, and vise versa. I had an expert take a look at it as I thought it was more of a computer set up I needed to fix, but no. Just the adapter didn't work. But hey it does give me at least one display.. oh well.
I bought this to split my TV and Wacom tablet with my computer. It would send the signal to the TV just fine. But not to my Wacom. I couldn't get both to work on this splitter. I haven't tried to use it on two TV because I don't need it for that now. I'm not exactly sure if other splitters would have faired any better. So it just might be what I was trying to do this and the splitter just wasn't designed to do that. I'm rating it at 3 stars for those reasons.
I purchased this unit to provide video feed for our digital projector in the living room. It does an admirable job in that function. Great Video. Beware though, that if the projector is turned off while attached the unit triggers a video shutdown on your video card for all feeds. The same thing happens if the projector is turned on while attached. The work around is to be sure to disconnect the DVI-D line from the third unit before you turn it off and only connect it after you turn it on. This may not be a concern if you just want a twin monitor, but if you are like me and are using Netflix or Hulu or something else to stream video from the internet on a projector, just be ready to work on hands and knees to plug and unplug it each time you use it. Not too much trouble really, but not ideal in our pushbutton society. =] By the way, to have your video back if the shutdown happens, just disconnect both cables, wait 5 seconds, then reconnect the one you wish to use, and voila video back. Great video!
I was not able to get this splitter to work with my configuration, which comprised a TV and a monitor. The monitor only works when the TV is connected but off, and the TV simply does not work with the splitter.
I had used this DVI splitter for an LCD Monitor and a Plasma TV. The Monitor was a straight DVI while the Plasma was a DVI-HDMI cable. Both cables were dual-link. In 1920x1080 mode, both screens looked fine so long as I wasn't doing anything too complicated or I was playing simple low-def videos.
The moment I tried to play something in 720p or 1080p, the video would flicker horribly on the TV. It would often lose and reconnect signal; very annoying. Also, even with low-res video, there would often been green lines appearing.
On top of all that, the LCD monitor always had to be on. If I turned it off, the TV would lose signal, no matter which device I plugged into the top connector or which device I turned on first! Also while the computer was booting, all the console text looked really garbed and unreadable on the Plasma screen.
Overall, this is pretty worthless unless you're doing something really simple at a low resolution (1024x768 maybe?) But it's really not more than what I'd expect out of a non-powered splitter.
It cost a fraction of what I saw it for in the store. I think it would work great with two identicle monitors. With my different monitors, after startup, the screens go blank... I think the issue is that card is trying to read the two monitors at the same time...
