About possible 3200×2000 apple displays.

As Tuaw pointed out Mac OS X Lion might support 3200 x 2000 pixels screens (it’s still far away from iphone4’s retina display pixel density), but what is technical possibilities of it?

So far, the only interface which could support such resolution is DisplayPort 1.2, which maximum is 3840 х 2400 @ 60 hz.

The only video cards to support DP1,2 is AMD’s Cayman (69×0), Barts (68×0, 6790), Turks (6570/6670) and Caicos (6450).

None of them officialy supports more the 2560×1600 tho, but maybe amd can write special drivers for apple, who knows..

Also, I doubt that Turks or Caicos can works well with 3d stuff at 3200×2000 resolution, they are just too weak for it.

Cayman is too hot and power hungry for macs (imacs probably this time ?). So, maybe it will be Barts. We will not see new AMD/NVIDIA cards until Q3/Q4 anyway.

    Hmmm..who is going to make those super-ultra high resolution lcd panels? Samsung? 😀

    200MB framebuffer, thats wrong (i think)

    4 bytes/pixel
    3200*2000*4 = 25 600 000 bytes = just over 24 MB

    but correct me if i’m wrong!

    ///right, just wrong button made it 8 times more.

    And what if they will just something like SLI for the iMac?

    SLI doesn’t make it to 3200×2000 on a single display

    Just when I was wondering if such resolutions are technicaly possible in consumer products at the moment, you are posting this stuff.
    I wish some of mac-centric sites would be at least HALF as informative, as your blog is. Most of those “tech journalists” are so clueless :/

    Its pure speculation at this moment, but I think that first products with those ‘retina displays’ gonna be new Apple LED Cinema Displays. Soon to be released Final Cut Pro X is going to natively support 4K resolution, so Apple need to release such hardware for video & postproduction proffesionals. IIL

    Well you could have simply changed the 200MB frame buffer to 24MB, fullHD resolution has a 7.9MB buffer, compared to that 24MB is massive! Just for a fun fact, those 3 fullHD monitor gaming systems use the same amount of framebuffer as the single 3200*200 monitor… 😛

    quick question: who manufactures the apple lcd displays right now? apple themselves? or do they buy it off samsung or some other company?

    Apple orders most of them from LG, I believe, at least as far as the iMacs are concerned. The Macbooks used numerous OEMs in the past. Not sure what it’s like now.

    If they’re going with major high-res displays then it would be a custom order, of course. Whatever OEM makes the best bid gets it.

    Each time I change the video card (once in 1-2 years) my home workstation Apple releases the updated mac pro series with the old GPUs (usually the same I’m throwing away)

    It’s nice when you pay 1,500 euros for a computer configuration which is 1-2 generations older than the rest of PCs on the market.
