Ivy Bridge GPU Will Support 4K Quad HD Video

We already know Intel is planning to build a better GPU for Ivy Bridge than what's currently available in Sandy Bridge, but just how much better it will be is the question. Intel provided a partial answer at this year's IDF event by detailing parts of the next-generation GPU, which the Santa Clara chip maker says will support up to a 4Kx4K (Quad HD) screen resolution.
That's a big improvement over Sandy Bridge, which maxes out at 2560x1600 (WQXGA). VR-Zone.com posted a handful of Intel slides revealing some of the Ivy Bridge GPU's inner workings. Of interest is Intel's Multi Format Codec (MFX) engine, which both supports up to 4096x4096 pixels and is capable of processing 4K Quad HD video.
Good stuff, though as Anandtech points out, it's worth noting that today's display cables don't support that kind of bandwidth. A 4096x4096 resolution at 60Hz with 24-bit color equates to around 36Gb/s, quite a bit higher than DisplayPort 1.2's 21.6Gb/s.

But do they solve the 24p (23.976 fps playback) problem with Ivy Bridge?

Two things:
1. At the rate Intel integrated graphics are going you wouldn't actually be able to render any games from this decade at 4k.
2. You can't get 4k or even 2k copies of films because those are the formats studios distribute to digital cinemas.
So essentially the hard part of displaying such a high resolution isn't actually displaying such a high resolution. It's coming up with the content.
Also: saying 4096x4096 @ 60 Hz isn't possible because of the display cable is like saying a car can't muster 500 horsepower because the fuel pump isn't fast enough. It's not the biggest reason.

Once Ivy Bridge gets going, the price of DP adapters would probably drop substansially (at least for the expensive brands).

36Gb/s........and u people thought streaming was gonna take over everything lol.
Name one ISP in the entire US that can provide that speed.
Exactly.

36Gbps is the raw uncompressed GPU to monitor rate.
Name one ISP that connects GPUs to monitors.
Exactly.

Does this mean future games and movies etc will have a larger field of view?
I don't 100% understandI saw a 103 inch flat screen TV playing GTA 4, how is that so big but does not support quad HD?
Would you be able to see more on say... a 30 inch quad HD TV than current 100+inch TVs?

So wait a minute... A sandybridge connected with a 6990 in Crossfire X will not support 4K res? Oh no!!! Well, I am pretty sure the first generation of 4K monitors will be insanely expensive. Maybe I would like to get an OLED version of that monitor when it is at a more reasonable priced... Which will be year down the line.

Since the 6990 only supports 2560X1600 no, it won't.
Unless you're pluggin in to your boards integrated video ports what SB, SBE, and IB support, doesn't matter.
Of course, as soon as Ivy Bridge supports it I would hope GPU makers start working their asses off to get it working.
