Did what it's supposed to do. Can now plug my older VGA monitor into my new graphics card.

This thing worked great!!! After trying just about everything to get my desktop on a Dell laptop to be shown through a projectors image, on the wall AT the same time, was like trying to get into Fort Knox!!!!I don't have any old style video port (blue in color) on my laptop, just HDMI and Mini Display Port. I connected the laptop to the ViewSonic projector via the HDMI cable I had and no matter what I did, I couldn't get the laptop's desktop to display on the wall and still see the desktop/use the mouse on the laptop at the same time. I could see the laptop's desktop on the wall through the projector but the screen on the laptop was black. I tried disabling the display drivers, one at a time, which I have 2 of on this souped up laptop: one Intel and the other nVidia, but nothing worked.I finally purchased this Mini Display Port to VGA video Adapter and as soon as I turned on the projector after connecting the cables up to the laptop, B-A-M.....the screen on the laptop's desktop grew black bars on both sides and as soon as the projector warmed up, the laptop's desktop was displayed on the wall AT the same time!!!! YEA!!!!! My wife can now see AND use her laptop's screen and the mouse at the same time as the image is being displayed on the wall where her students are looking!!!!!My wife's happy......she's the one using the laptop with the projector when she's teaching classes.

Fabuleux, génial, je branche et ça fonctionne parfaitement, surtout après avoir galéré avec d'autres produits absolument nul. Un seul bémol le tarif d'expédition très prohibitif, 9,99 euros pour un envoi Chronopost de quelques petits grammes !!!!!

Convierte la señal sin perdidas. Utilizo dos a la vez para dos monitores con una ATI 7950, junto con el tercer monitor directo a la tarjeta consigo hacer eyefinity.

Don't use MAC mini-display adapters with Dell laptops... use this Startech.com adapter it works brilliantly. I bought a new Dell XPS1702 laptop and had trouble with my MAC minidisplay port adapter even using it with 2 different VGA cables! One worked the other didn't. After looking through forums I found this article(see below). I took the advice and purchased this adapter and hey presto both cables now work perfectly! I use my laptop onsite and need to plug into many different screen/projector setups and I cannot take the chance on having problems plugging in. I also purchased the Startech DVI connector... anyway please read this:-------------------------------------------------------------------------------------------------------------------------------------------------Hopefully this will be helpful for those buying new laptops, as I'm sure I won't be the only person around that will run into this problem in the near future with Windows 7 and VGA Min-DisplayPort adapters from Apple.TL;DR version for those that don't care about the tech: If you buy a new Dell laptop which you plan to put Windows 7 on, check to see if it has a VGA port or a Mini-DisplayPort. If it only has a Mini-DisplayPort you will need an adapter to connect to most of the projectors you are likely to encounter which take a VGA connection. Don't bother with the one from Apple, it seems to fail on many projectors when using Windows 7. Buy the StarTech model MDP2VGA, it seems to work without issue from what I've tested. The Apple one will work in some cases, but you don't know for sure till you try, so it's most likely safer to get the StarTech one. I'm not sure on other brands like MonoPrice yet, but would like to hear reports.Tech Stuff: I recently got a new laptop, a Dell XPS L502X. It had not occurred to me to check to see if it had a VGA port, as all the laptops I've ever owned have had one up till now. Well, I got it and it had no VGA port, which is a problem for me when I go to do presentations. After showing it to some colleagues, we figured out it had a Mini-DisplayPort, which up till now you would mostly only find on Mac laptops (which is why when you look around for a Mini-DisplayPort to VGA adapter, most of the ones you will find are from Apple). I went to my buddy to see if the Mac Adapter (Model MB572Z/A or A1307 depending on where you look) would function. Well, it did work on the monitor in his office, so I thought I was good to go. I went to a few conferences, and found out I could not get the laptop to connect to the projectors there (at least not in Windows 7, it would connect in Linux so I knew the adapter worked). There was also at least one at work that did not function. We even tried updating the firmware on the A1307 (yes, it has a firmware update), but it was already at the newest revision. After doing some playing around, I figured out it would not connect to a monitor or projector that did not send EDID or DDC2 info. I replicated this by ripping pin 12 out of a VGA cable. EDID and DDC2 are protocols your monitor/projector/display uses to tell the computer what resolutions it supports, along with other details. If you see a monitor in Device Manager that says "Non Plug and Play" it likely is not sending EDID/DDC2 information. The Dell XPS laptop would connect ok if I first hooked it to a monitor that supported EDID/DDC2, then unplugged just the VGA cable and walked it over to the non-plug and play projector to hook it up. I also borrowed an EDID emulator from a co-worker that man in the middles the VGA cable and sends a mock EDID signal, and then the Apple DisplayPort adapter would work with my Dell on a projector it would not work on before. Well, this EDID emulator is kind of pricey, and it along with a VGA cable takes up a lot of space in a laptop bag.Solution: I ordered the StarTech model MDP2VGA Mini-DisplayPort toVGA adapter, so far no issues and it seems to work fine on a non plug and play projector where the Apple adapter failed. Hope this info helps someone.
