I'm seeing news that the new Mac Pro's will do HDMI 1.4, but can't seem to confirm if the new Macbook Pro's will have this as well. I'm curious if it includes HDMI 1.4 and if that will permit it to do 2560 x 1440 over HDMI (for a third screen at that resolution).

I need to know if I should be looking for daisy chaining solutions or if I can just run all three from the existing ports!

The retina macbook pro's have had HDMI 1.4 for a while. Unfortunately, OSX drivers wouldn't allow it, but with a driver hack I was able to do 2560x1440x60hz on the hdmi port (2012 model).

Still downloading OSX 10.9, so not sure yet if this restriction is gone in Mavericks....

I upgraded to mavericks, and haven't re-hacked the driver. Hooked my 4k display up to the HMDI port, and it did 3840x2160x30Hz.

NOTE: I have the 15" - its possible the integrated video still might not do it out of the box, so no guarantees on the 13"

How to get other resolutions?

http://www.apple.com/macbook-pro/specs-retina/

3840x2160 at 30Hz via the HDMI port is specified to work on all Haswell rMBPs.

It looks like Apple just "hacked on" the ability to work with 4K monitors. But if I want to use HDMI with a 2,560 x 1,600 monitor, what can I do to enable such resolutions? Do 3rd party resolution switchers work? Do I need to do command line editing? Or driver file editing?

Thanks,
