Reviews for Mini DisplayPort to VGA Adaptor

The adapter is an active adapter which converts a digital signal with pixel clocks up to 180 MHz to an analog signal. This one piece of information should be mentioned in the technical specifications because it directly relates to all the resolutions and frequencies allowed by the adapter. The FAQ has a mention of maximum screen resolutions but it's not precise.

I have a Sony GDM-F520 that can support 2048x1536 at 85Hz. Using GTF timing, the adapter will allow 2048x1536 at 41 Hz which is too slow for the CRT (minimum 47 Hz). However, CVT-RB timings also work and will allow 2048x1536 at 51 Hz. It also allows 2100x1575 at 49 Hz. CVT-RB timing may cause an issue with the left and right edge positions on a CRT though.

I recently purchased a Mac mini (the one with the fusion drive) and hooked it up to my Toshiba TV via HDMI. The display was a letdown coz it could ramp up to 1080p or 1080i - which is HD display.

My TV did not have a DVI input.

I could not get my latest mac mini to go 1920 X 1080 - when my company laptop could do so. Apple support could not help much.

I eventually pulled out an OLD 2009 Mini DisplayPort to VGA Adaptor from my white macbook, hooked it up to my mac mini's thunderbolt display port and it worked. The resolution is even better than HDMI, the only small problem is that I have to link the audio separately.

Like others who've posted here, I'm having to return this item because it's the wrong size for my MacBook. Before ordering, I checked 'About this computer' but it didn't say what kind of display hardware I had (just told me that no display was connected), so I examined the photos of the adapter and, as it looked the same as the display port on my MacBook, I assumed that it would fit okay. When it arrived, though, it was way too small (mini, I guess).

So, for anyone who has a plain old white MacBook like mine - it DOES NOT HAVE A MINI DISPLAY PORT, so don't waste your time and money ordering this.

I feel annoyed with Apple for not explaining the difference between an ordinary display port and a mini one. I'm not a techie and I don't want to have to go and dig out all the literature before buying a small accessory - I expect there to be enough information within the product description for me to make the right choice.

And I still don't know which (if any) adapter's compatible with my MacBook.

If you have problems with your adapter, try disconnecting it from your MacBook Air while maintaining connection from the adapter to your projector or any display with VGA port.
Alternatively, check it out under the finder, which should be one of the icons on your dock.

Forget all the other bad reviews because apple has made ( i think ) a new version of it
( also cas it has a box as the cover unlike the earlier ones). IT has two mode... mirror and the other one is that only presentations will be seen on screen....nothing else.
Well it works perfectly with my LG and beautiful RESOLUTION! ( didn't expect that! ).

We use these at our church to display song lyrics on a screen. So far, we go through about one of these cable each year. Not cool apple. Not cool.

My adapter works great when hooked up to a second monitor (read: when I don't have an audience) -- but after only a few months of use, it has completely stopped working properly when hooked up to a projector. Totally embarrassing when I'm in front of clients.

Just bought this thing it embarrassed me in my meeting as the VGA screen drew BLANK! So much for it just Works???

I returned it to best buy and they said I had to go to preferences and turn it on to detect it.
Instructions in bold would be nice or web references.

But no!!! Thanks apple

By the way iCards is weak

I connected the Mini DisplayPort to VGA Adapter to my 2011 13" MacBook Pro and to my 60" Sony TV and it worked perfectly.

I used this thing a lot and it eventually burnt out like a bad fuse. As best I can tell, all brands are equally worthless. I expected it to last as long as my macbook will, but it looks like this is just the beginning, and I'll be replacing these adapters until someone gets it right.
