Reviews for Mini DisplayPort to VGA Adapter

I bought this adapter with my new aluminum unibody macbook a couple of weeks ago. I immediately rushed home to try it out with my samsung LN46A550 TV... To my dismay the TV nor the macbook recognized that they were connected to eachother...

After some hard research and digging i found out that this particular adapter only supports up to a 30" display. For whatever reason, apple made it this way. So i returned my adapter and asked employees at the apple store what was up with only supporting 30" or smaller displays. To my surprise i was told good news and bad news... The good news, theres another adapter coming out for my macbook with mini display port... The bad news is that it is not shipping yet and they dont know when it will start shipping. My guess is it has something to do with signal strength for the display size....

Either way, I have an awesome new computer and im just gonna have to wait to hook it up to my 46" TV.

I am confirming another review and post regarding the Thunderbolt video connection to VGA adapter on a week old 2012 MacBook Air. After an afternoon of disappointment attempting connections to several different monitors using several different cables and thoughts that the adapter was broken or not compatible with the Thunderbolt port, I concur that there must be a software/firmware error in the 2012 MacBook Air related to the Thunderbolt port so that it will not connect to *any* external monitor using the VGA adapter without rebooting the machine with the monitor attached. I confirmed this tonight.

Nothing wrong with the minidisplay to VGA adapter as an interface. It is perhaps not the most ideal design, but it works. Apple, c'mon guys. The company generally makes good stuff but you've got to get the bar raised again or you've lost it... Professor of EE...

In addition to the Mini-DVI to VGA adaptor, I purchased this Mini DisplayPort to VGA adaptor for my dual monitor setup on Mac Mini (2009). Worked great with my first set of lower resolution monitors that only had VGA in. However, upon upgrading monitors to higher resolution, I found out the hard way that there is a limitation on the resolution this adaptor will support. While the Mini-DVI to VGA worked fine in 1680x1050 mode, this adaptor did not! It only would work at the next resolution down, 1600x1200, not acceptable for identical dual monitor setup. Discovered that it was because of the analog output of this adaptor will not support resolutions this high. Fortunately the monitors also had DVI connectors, so I purchased the Mini DisplayPort to DVI adaptor instead and used theMini-DVI to DVI adaptor that came in the Mac Mini box. Everything now works fine but I am out another $29. Moral of the story: Go all DVI for best image quality and support for highest resolution, if you can!

I had just bought one, and was apprehensive about it. But it worked beautifully with everything I hooked it up with, including my 46" SAMSUNG TV(yeah, samsung, ). after a month of light use and lugging it between home and school, it just crapped out. Just like that. no warning or anything. Doubleyou-tee-eff, Apple. Also $30? Fo-real? Apple...$10. No more than $10.

I recently bought the Adapter at the Apple Store after waiting in line for around 20 minutes. This adapter was around $40 with tax which is outrageous considering its size. The adapter worked almost perfectly on first boot-up except for two exceptions:

1. I couldn't type on either monitor on they first try. Once I rebooted I could type again.

2. The colour is off even though I calibrated.

In conclusion, the adapter was not worth the money that I put into it but will be EXTREMELY useful in the future.

$29 is of course too much to pay for a video dongle.

on top of that, my monitor right now always keeps re-syncing (blanking out and then realizing that yes, it does have input). it could just be this monitor model (samsung syncmaster 216bw), but definitely does it on several different ones around the office.

i'm hoping that when the dvi one comes in the mail that it'll stop the constant blanking.

I have a late-2010 13" MB Air and use this adapter with various monitors. It appears that the VGA timings or signal strength on the laptop are marginal at higher resolutions (1600x1200 and above). The effect is that you periodically get zig-zag bursts across the entire screen. This is the analog VGA signal slipping between scanlines.

The reason I'm mentioning this on the adapter page is that the build quality of the adapter appears to contribute to this. Perhaps there isn't proper shielding. In any case, I have tried three of these adapters and some are worse than others.

Hopefully this issue can be fixed in the MB Air so that VGA is more usable at higher resolutions.

Variables I have eliminated by trying different options: monitors, VGA cables, computer (2009 Mac Mini has no problem with same monitor and cable), USB or no USB attached, wireless networking disabled, and locations (home and office). Things that definitely fix it: using a DVI adapter or resolutions under 1600x1200 with VGA.

So, if you have a single monitor, get the DVI adapter instead. If you're doing presentations, you have to use VGA but switch to a lower resolution.

Maximum resolution seems to be limited to 1600x1200 and 1920x1080. I'm using an Aluminum MacBook (2008). My 1920x1440 CRT is crippled.

This cable does the job but the connector screws to the VGA don't fit properly and I needed to use electrical tape to keep them together.

Also, I work at a College and we provide these adapters for student loan. It is VERY frustrating to purchase a new $34.00 adapter every 4 months because Apple keeps changing the "standard".

I connect my new MacBook Pro to an LG 22" display. It's resolution is 1680x1050. For some reason, It'll let me output 1680 to the monitor, but the display won't show anything but a black screen. VERY annoying, since my old MacBook with the miniDVI port or whatever worked PERFECTLY! Although one absolute upside to this port is that the connection is a TON stronger (the adapter won't just simply fall out like the miniDVI one) and that it actually supports the PowerSave mode for my display.
