Pros: The product will work if you know how to use it and have the correct hardware.

Cons: You can't just expect it to work if you don't have the right hardware or know how DVI splitting works.

Overall Review: When splitting DVI, you have to remember that all of the connected devices have to support Dual-Link DVI I/O. If you try to sit using DVI-I or DVI-A which are analog signals they will not be able to support the bandwidth that it needs to display both videos correctly. For example, you can't use DVI-A or DVI-D to output 1080p 120hz or up to 240hz stable because they simply do not have the bandwidth capabilities, keep in mind that HDMI cannot handle more than 60hz stable. So if you want to send images to a capture card or 2nd screen you have to be sure they support DVI-D I/O and your desired resolution and frame rate. I have a Dual-Link DVI splitter that I use to go to my 144hz monitor and capture card that captures at 1080p 30fps, I have to run my games at about 210fps so that the screen can get 144fps and the capture card can get its 30fps. I set it a little bit higher just because I can. I hope this has helped some misunderstanding.

Pros: this product does what it was meant to do. split 1 image in to 2. via 1 port. it works with crossfireX mode if your trying to use the happauge HD capture card. and allow you to record both the image with out a black screen. it does allow HD sources. but they both have to be reponding to the same HZ level for it to show. you can configure this via the AMD Cat control panel to turn on the HD to 30 HZ or higher if the other source supports it manually.

Cons: here are the cons for this product. users may have problems trying to configure sources if there trying to record to other source. depending on the game i was trying to use to record this image with it does not like to register with the EDID profiles this adapter is meant for the EDID to be turn to off. or to be run under the General PNP moniter settings. if your trying to capture sound you will need to have other cable that can pass the sound to the device your trying to record. other then that. thats all i can find.

Overall Review: when i first got this product it worked. it allows me to capture as long as i dont try to detect the source of one of the moniters. but when i tryed to capture crossfire X for game footage. it would give me a black screen finally i had to update my sources to read at 30 hz since the capture card i was using only allows 1920X1080I @30hz sources. but it does work. it just takes time to set it up.

Pros: works

Cons: none yet

Pros: It does what it seems to advertise. It splits the DVI-D output into two identical outputs. My main 23" monitor is mirrored as perfectly over to my HDTV as you could expect. I've read some reviews that said these kind of splitters leave the image darker or fuzzy but it looks great on both screens. Almost like I have them both plugged into the video card directly. It also seems very sturdy. Not at all like the cheap flimsy piece of crud it was said to be.

Cons: Everything was pretty much plug-and-play. I connected the main screen first and it looked great. But as soon as I connected the second, the first screen was instantly distorted with lines and mixed coloring. When I turned the second screen on the first one went back to normal. Now I either have to have both screens on or the one left on gets scrabbled. It gets an egg off for this. I might be able to find a way around it or it might have to do with the cables I'm using, but its the one thing that doesn't work perfect.

Overall Review: If you're looking to have two different monitors, this isn't the device you want. You're better of looking for a video card that supports multiple displays. If you want to have the same thing on two monitors, this should work great. It doesn't give you the option to set multiple resolutions though so make sure that both screens can display the resolution you want to use. I'm using mine with an old GeForce 7950 GTX and splitting the main monitor along side a second vga monitor. Altogether I have 4 screens, two at the desk and two in the living room, both putting out the same two displays. I had the vga split a while back but now this allows me to essentially mirror my computer over to the living room w/ a wireless keyboard/mouse.

Pros: Nothing

Cons: Product does not function at all. PC recognizes device connected, monitor scans for signal, but signal doesn't reach display. Really should have checked reviews before purchase--lesson learned.

Overall Review: Look for a different solution.

Pros: Doubles as a blackjack

Cons: Simply doesn't work. Yes, I'm using dual link cables and I'm running it out of a Fermi 470.

Pros: Works great, does what is intended. Mirrors images between my 42" LCD screen TV and 23" LCD monitor. Supports 1920x1080 output to both monitors.

Cons: I leave TV off most of the time, however when i turn it on it usually causes some discoloration on the 23". It only lasts a couple seconds so its not a biggie at all.

Overall Review: Works great.

Cons: I plugged it in to my Mac Mini and my DVI-D monitor, and it didn't pass through the signal properly. I may be using it incorrectly (to enable to computers to access the same DVI-D monitor, albeit only one powered up at a time), but so far I'm concerned I need to return this item.

Overall Review: Still developing...
