question about Macbook pro with retina display

[MR1cntrl]

apple said here
http://www.apple.com/macbook-pro/specs/
in the part that concerns the display it has the resolution of "2880 by 1800"
and said olso in the same page the maximum resolution of the graphics card that's assigned to the retina display (the built in display) is "2560 by 1600 "
did this graphics card really cannot handle the display ?
if that is correct then why apple did choose it?
and here another thing this resolution that the graphics card support doe'snot have the same accept ratio of the display so in what resolution will the run by?
plz help
i olso checked the specs of the graphics card on it's website was written that it can handle resolution up to "3840 x 2160" if it has 2GB of GDDR5 memory and apple offers only 1GB of GDDR5 memory
and i think that we cannot upgrade the graphics card memory
thank you for helping very much

2880x1800 is the max resolution of the internal display.
2560x1600 is the max resolution of external displays.

Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on up to two external displays, at millions of colors

Seems like you might have misread. The exact quote from their site is:

Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on up to two external displays, at millions of colors

Retina display: 2880x1800
Externals: 2560x1600 each.

----------

2880x1800 is the max resolution of the internal display.
2560x1600 is the max resolution of external displays.

Beat me to it

Another bit of info - OS X itself cannot run the retina higher than 1920x1200. There are some things (full screen apps/games) that can support higher. But while even OS X's own desktop is limited to 1920x1200, my windows 7 virtual machine can run the full 2880x1800.

Hopefully the next iteration of OS X gets a bump to the resolution limit.

But the display looks gorgeous and it's nice having a 15" with higher than 1440x900 anyway...

Strictly speaking, OS X can run at the native 2880x1800. It just takes a hack right now. My guess is that Apple assumed nobody had good enough vision for 2880x1800.

This is incorrect. Things are running just peachy over here.

What's the trick then? I've been googling and found nothing for enabling it in OS X? Would be much easier for me to do it in OS X than in a Windows VM...

Alright, found switchresx works, but my system is unusable with it since it totally goes ballistic with the mail app... Renders things totally blurred and distorted when you scroll in it...
