Hi,

I have a Retina Macbook Pro. Currently I run it with 3 monitors.
Thunderbolt to 30inch Dell monitor with a box that converts the signal to DVI
Thunderbold to a 27 inch non thunderbolt iMac using a mini-display port cable
And the laptop screen itself.

I have an Apple 24inch LED (non thunderbolt) monitor. I'm wondering if there's a way to add this in via the unused HDMI port on the Retina laptop.

I see a lot of mini-displayport to HDMI but not HDMI to mini-displayport. My impression is that the mini-DP to HDMI only go in that direction.

Any advice would be appreciated.

Thanks!

Can't you just flip the cable around and plug the HDMI into the computer and minidisplayport into the monitor?

My impression, which could be wrong, is that this cable only goes in 1 direction. mini-display TO hdmi... and not hdmi TO mini display.

From what I have seen before, I believe that you are correct that the connector only works in one direction.

Slightly OT but was just wondering how your experience was using 3 displays with the current gen rMBP. Any issues with GUI lag or stuttering?

Sorry for the late reply. I never saw this.

I almost always use 2 external monitors and the internal monitor of mm Mid 2012 Retina MBP. It works really well. Sometimes there can be some GUI stuttering when I'm switching virtual desktops but I'm often running a lot of programs and Parallels Virtual machines as well. Often times it's very smooth as well.

I'm trying to get a 3rd external monitor out via the HDMI port. If I do then I'll run the laptop with the lid close and who knows it might even improve because it's pushing less pixels...

Should work with a passive converter. You need an hdmi to display port cable, or a hdmi to dvi and then dvi to mdp
