That’s pins 1 and 6 for those scoring at home. I went with the red out and the red return. Then you’ll be connecting two pins on the VGA end. You also need a resistor that can be bought from any sort of electronic store (Fry’s, Radio Shack, etc) I went with 85ohm.

You can buy one from Apple or from Monoprice.

It’s easier than you think.įirst, you need a mini-displayport -> VGA adapter. I thought I had written this up years ago, but I could not find it. I reported back on Twitter that a dongle fixed the issue and had more than one request on how to build a dongle. And now it turns out that Chrome (as well as other browsers) can really benefit from the video driver being loaded as well. We’ve been connecting these for years for those customers who use video intensive servers, or those who run a linux build that won’t boot headless. It will force a Mac to load the video driver and take full advantage of the GPU. I decided to connect a Mini-displayport -> VGA dummy dongle and sure enough, that took care of the issue.Ī dummy dongle mimics a monitor being attached to a Mac. There were some good responses, and we decided it was probably the “headless” part of the equation and not the “Mac mini” part.
