Does the new Macbook Pro 15" (late 2013) supports 4K via Thunderbolt/Displayport?

"there is no display port to HDMI adapter that goes higher than 1080p." - but it should not be impossible to build one, right? Displayport does 4K@60Hz and HDMI2 does 4K@60Hz.

100% correct.

We were talking about a future product that would be a thunderbolt (PCIe) based GPU that would add an HDMI 2.0 port to an existing mac.

how does that work on windows?

why would you need an external GPU when you already have a, let's say Iris Pro, that is perfectly capable of doing 4K@60Hz via Thunderbolt?

Its about driver support (which is currently missing in Mac OX X)

Should work without modifications on a normal windows installation.

It works on Windows because the 750M and Iris pro drivers support it.

On OS X Mavericks, the drivers don't support it, or there is something else in the OS that supports it.

""there is no display port to HDMI adapter that goes higher than 1080p." - but it should not be impossible to build one, right? Displayport does 4K@60Hz and HDMI2 does 4K@60Hz."

I guess, but it's probably going to be very expensive.

I don't know, can't speak on such matters as HDMI 2.0 products are not shipping and won't for at least a few months.

but... what's the cable-setup?

It's not nearly as bad as that. There are < $40 adapters right now that do Thunderbolt to HDMI and gt 4K@30fps - with plenty of posts confirming this to be the case. The adapters DO have to be active, but they don't have to be an entire GPU. (Provided your GPU+drivers suport 4K@30) So I can't imagine things would look different at 60 Hz. But again it won't matter if most displays adapt DisplayPort.

There is great hope/anticipation in the community that Mavericks will get an update to enable multi-stream support, motivated in part by the Mac Pro release.

Can you show me one? I can't find any that go higher than 1808p.

It's not "thunderbolt" to HDMI btw, it's displayport.

I still can't get over how blind-sided the entire industry was by this... 4K @ 60Hz by 2014 - wow, none of us ever saw that coming. Honestly, this is the first time in 25+ years I have to buy a new computer just to use a state of the art display. What ever happened to putting in a few years of future proofing?

I'm not speaking from first hand experience, but this adapter has been a favorite for people with older Macs using the 39" Seiki 4K monitor at 30 Hz:

Awesome...thanks.

I wonder if the ability to add multi stream DP will put a higher price on it though...

NiqueXyZ: "So in order to get this you have to run windows 8 on your mac"

How about Windows 7? Will it output 4K @ 60Hz? If so, which editions (Home, Ultimate, etc.) of Windows 7 -and also Windows 8- are capable of doing this?

Well, the hardware supports it, so as long as you can find drivers Windows 7 should work fine too. With proper drivers, the edition of Windows 7, 8, or 8.1 doesn't matter - all should work.

Thank you, kogir. I had purchased the 1st gen rMBP, my only Mac purchase, which I had returned as I decided to wait for Haswell or Broadwell update. Before returning I had installed Windows 7 and as far as I remember, upon the installation, Windows 7 finds and installs the drivers for each hardware. Which driver are you referring to? Is it the one that Windows finds, or should I look for the updated driver of that or another driver?
