How do I connect an external display to my Macbook Pro? I have a Macbook Pro (Late 2013). I'm trying to mirror the display on a LG M2035A. The monitor accepts VGA input. The monitor comes with a VGA cable. So, I purchased a HDMI to VGA converter, to connect to the monitor. However, my Macbook doesn't seem to detect the external display. I think my VGA and HDMI cable function properly, because when I connect the monitor using this to my laptop running Windows, it functions perfectly. Is there a workaround, or something I'm missing?
DVI is far, far superior in terms of the Mac sensing the capabilities of the display and in terms of quality. Go that method if you can.

If your VGA adapter isn't working with OS X, you could contact the adapter vendor for support. Not all of them are high quality and even the high quality ones don't work with all displays/projectors.
