I read a rumor about 4K screens being implemented in the new MBP, but it had no basis or sources. It's basically a dream at this point, but awesome if it happens. Regardless, I need a new MBP, mine gave out on me and I already had it repaired once, so hopefully this is a substantial update to the line.
 
I run 3 screens at 1920 x 1080 on a 3 year old laptop and it runs extremely smooth. The GPU in my 3 year old laptop could easily handle a 4th 1920 x1080 screen if I had space on my desk.

So if my 3 year old laptop can handle 4k resolutions (4 1920 x1080 screens), than laptop GPU"s from 2013 should also easily do it.
 
I'd be happy with a 4k res. They could just double the existing resolution :

1920 x 1200 -> 3840 x 2400

In all seriousness, a 17" rMBP @ 4K would be killer I would buy one in a second if I could get 32GB RAM BTO.

I am convinced. That's it.
I am looking forward to ordering that monster before christmas.:D

Expect that's not 4k... That 1080p
 
Well, Intel HD4000 and higher do support 4K output. The tricky thing is to actually connect it to the monitor ;) I don't even know if OS X has support for such resolution.
 
The rMBP is almost 4K, at least the screen itself. It's definitely good enough to watch some 4K videos and notice the difference.

4 screen running 1080p is not generating the same amount of pixels as 1 1080p screen. I don't have to explain that do I?

And it doesn't take a genius to figure out that 4 monitors running at 1080p resolution is running the same amount of pixels as a 4k resolution screen?

You try and run a game on 4k "with your labtop gpu" and tell me how that works

My laptop that is used in this setup is not intended for gaming since it has a workstation class GPU, instead of a consumer / gaming laptop GPU.

Why should I run games on 4K when it's intended for professional uses?

The thing is, unless you're actively sweeping across all those monitors at the same time (impossible) you can't say that's the same as running 4k resolution. What you're doing is, having 3 1080p displays sit there, and having 1 actively used. No doubt they are capable of supporting it. But that's not the same thing as running a true 4k resolution

4k needs some serious software optimization to work in OSx though, because the current retina is still pretty poorly optimized.

HD4000 has absolutely no problem running 1920x1200 HiDPI resolution (which renders to a 3840x2400 buffer).
 
I'd rather they not go 4K just yet. The rMBP had struggles with just the retina display, and for the large number of us who used one to replace the lack of a decent MacPro, it'll be hooked up to at least 2 external displays. 4k still isn't justifiable. Give it another year or two.

Why would I need to do that on this professional laptop? I don't work in the Arts industry.

This may seem like a silly question...why do you want 4k then when you cant really get any use out of it other than 'I've got 4k...awesome!'.

For me it's because I just want anything that brings back the 17 inch.
 
Technically, that's quadrupling the resolution.

Uh, as far as I remember 2(ab) = 2a2b. So, doubling (1920x1200) is (3840x2400)... He didn't say double the pixels but double the resolution, which is equivalent to quadrupling the pixels.

Not in Mavericks.

Because the scaled 1920x1200 option is not very good looking on the current Retina screen. It's quite blurry. With a 4k screen that resolution would be the "Best for Retina" optimization, as opposed to the current 1440x900 which is the "Best for Retina".

In that case you want a 17" laptop...not a 4k screen :) We dont need 4k to be present for a 17" laptop to be released.

Absolutely . But apple canned the 17 inch . So to bring it back might take something special . Like the bragging rights of making the first 4k notebook
