StarTech.comMini DisplayPort to DVI Adapter - Mini DP to DVI-D Converter - 1080p Video - VESA Certified - mDP or Thunderbolt 1/2 Mac/PC to DVI Monitor - mDP 1.2 to DVI Single-Link Dongle (MDP2DVI)

I purchased two of these adapters for use at home and in the office. It's been working fine but a problem I have been having is when I am on my wifi network and using my second DVI display via this adapter, the network experiences major packet loss. This happens both on my home linksys wrt54g router (with dd-wrt) and in the office using my android wifi hotspot. I think this might be a compatibility issue with OS X Mavericks as I don't recall having this issue with OS X Lion. Happens with my wife's macbook air also so must be an OS X or hardware problem. Startech support says "works for us."If you're considering buying and want to use wifi be warned. What I do to work around this is use their Gigabit ethernet USB adapter and that works flawlessly. Video quality is great, no issues otherwise but the wifi issue is a hassle.UPDATE: Ok so after I post this review I finally manage to find a fix. Turns out it was the wifi channel in my router. Set to channel 1 and works perfectly now on wifi. Changing my rating to five stars! :) Here's a post with more information on the issue - [...]

This adapter works well and is much better made than the less expensive versions from Syba. I bought two Syba adapters and threw them away within a few months of light duty. Both gave me problems right away and then quit completely.I haven't had the StarTech adapter for very long but can already tell that its a superior product. The build quality is immediately evident. And not once has it lost the signal, had to be reinserted, or otherwise jiggled to make it work. I've already bought a second one for my briefcase.Don't go cheap. Get this one that actually works as advertised.

Bought a HP Z4 G4 refurb PC. Amazing fast but comes with a high performance Nvida card with 4 outputs and mini display port. I have an adapter for the mini display port to a display port and DVD input on the other end to the monitor. NOPE. It works on one monitor, but not on two others ? ?This mini display port to DVI (with the pin) works, but I had to put the monitor right next to the PC (which is on the floor). Finally the monitor works with this PC. But the PC is on the floor DOH !Have to look for a longer cable or extension of DVI (with pin).The 3 feet is quite short even if you have it on the desktop as many PCs are pretty long. Just a warning !

These work perfectly after a log of trial and error with other setups. I previously had the 27in Thunderbolt Display from Apple for about a year and a half and couldn't take the glare of the monitor (I could see reflection in movies and videos, very annoying!). Ended up selling it and got two Dell monitors.I have the following setup:- Macbook Pro 2012 Retina Display with two Thunderbolt ports- Two Dell UltraSharp U2412HM monitorsI took advantage of the two thunderbolt ports on the Macbook and initially used a VGA to DVI video adapter but the color quality wasn't there. I used different software color setups and it still looked terrible. Did hours of research and found these StarTech adaptors and they worked PERFECTLY. After hours and hours of researching and fiddling around, I have a setup I'm really happy about. 5 Stars!

I had been using Apple's Mini Display to DVI adapter. It worked OK at first but eventually it became unreliable. I often had to pull the DVI plug in and out to get my Samsung monitor to work This process sometimes took 20-25 minutes. This StarTech Mini Display Por to DVI adapter works flawlessly. I've been using it for an older MacBook 13 and my new MacBook Air 11". It worked the very first time without incident and continues to work. Save your money and go with this adapter instead of the Apple one.

I used to use a MiniDP to HDMI converter to connect my MacBook to a LCD monitor. From one month ago, it starts showing flickering or color dots. I thought it is the LCD showing age, and thinking buying a new monitor. Then I bought this to connect to DVI port, then it works perfectly. I am very happy with this purchase - save me $200 for an unnecessary monitor purchase. I still cannot figure out HDMI port issue - whether converter, or running at too high pixel frequency with PC display than HDTV, which is what HDMI designed for. But, this works perfectly for me.

I have a high-end video card by EVGA, and this connector (mini display port) is _required_ in order to accommodate a Flight Management Computer bit of hardware on my Flight Simulator X setup. Why pay nearly $40 at big-box stores like Best ____, when you can get this great item from trusted AMAZON.com?I have always been happy with SIIG equipment, this unit works well and costs less than $10 which beats the heck out of similar units at four times the price in retail stores!RECOMMENDED!

I have a MBP 15" early 2011 and use a Samsung 24" monitor for my desk. I previously used a Kanex VGA adapter to go from my MBP mini display port to the VGA adapter on the monitor and had endless problems with the Samsung going black for a few seconds and then coming back on. It was a frustrating situation.I decied to buy the StarTech MDP2DVI adapter because of the price and reviews here on Amazon. Most importantly was that my monitor had come with a DVI cable and port (this Samsung display supports both VGA and DVI -- I wish it supported HDMI, but oh well).This product works perfectly with no blinking, blipping or belching and the display is crisp and clean enough for my purposes.
