Can the latest rMBP (late 2013) drive a 4K monitor

[np3000]

Hello,

Looking at this monitor --> http://www.amazon.com/ASUS-PQ321Q-31-5-Inch-4K-Monitor/dp/B00DJ4BIKA

Can the latest rMBP (with/without the dGPU) drive this one at full 4K resolution. I know that it has HDMI out at 4K but only at 30Hz, which probably does not work.

Thanks

EDIT: There is an answer about using displayport 1.2. However, it appears each one will only drive 2560x1440 (even though the spec goes beyond that). You can drive two monitors at 2560x1440 (apart from the laptop) but not 4K.

Yes, One.

HDMI video output
Support for 1080p resolution at up to 60Hz
Support for 3840-by-2160 resolution at 30Hz
Support for 4096-by-2160 resolution at 24Hz

thunderbolt 2 supports displayport 1.2. Displayport 1.2 can do 4k at 60 hz...which is what you want. So no, you don't need to use the hdmi port.

Thank you. Looks like displayport 1.2 is the option. The monitor requires two HDMI 1.4 cables to drive 4K, so not possible with the rMBP.

That monitor DOES support display port 1.2.

Why does nobody read what I post.

The new rMBP supports 3840x2160, and 4096x2160 out of its HDMI port.

You can't do 4K with the Thunderbolts, they max at 2560x1600. But you can out of its HDMI.

Only 24hz would be no good for anything but media.

Oh, nevermind, then. Reading comprehension fail.

According to the thunderbolt 2 specification it SHOULD output 4K video at 60Hz, apple doesn't mention if the rMBP can do it though which is what all these posts are talking about. It has the same chipset that supports it as the mac pro so theoretically it should be able to.

Related data point - I can use my 2012 15" rMBP with 3 IBM T221 4K monitors:

2 IBM T221 monitors connected to 2 Thunderbolt ports running at 3840x2400 @ 31 Hz
1 IBM T221 monitors connected to HDMI port running at 3840x2400 @ 17 Hz

This set up works fine, and I can use the internal LCD screen at the same time.

I also use my 2012 15" rMBP with a 50" Seiki 4K TV at 3840x2160 @ 31 Hz over HDMI.

This set up works fine as well.

To answer your question - I'm sure you can connect that monitor and use it at full 4K resolution at 30 Hz.

4K @ 60 Hz is more complicated. There are multiple questions to be asked.

Q1. Can this monitor be driven at 60 Hz using 2 cables, with the screen behaving as 2 separate display tiles, and not a single large display?

A1. This almost certainly works with the dedicated GPU. I don't know if it works with the integrated GPU.


Q2. Can this monitor be driven at 60 Hz using 1 DisplayPort cable (MST)?

A2. I have not tried it, but I read that MST is not supported on 2012 15" rMBP.. Thunderbolt 2 adds support for MST, so this might be possible on the new 2013 model.


Q3. Can this monitor be driven at 4K @ 60 Hz with the screen behaving as a single large 4K display?

A3. This requires driver support, which seems to exist for Windows (at least for NVIDIA), but not for OS X.
