    With MacBooks Retina 13" can you connect two external monitors with resolution each 2560x1600?

    Not talking about Thunderbolt displays, but other brands like ASUS, LG, SAMSUNG, etc.

    Has anyone tested?

    Any links, videos?

    Many thanks

    I imagine the graphics card would buckle, if it was even possible. I could be wrong, however.

    Officially, it can. I have no problems doing that with mine.

    There's no reason why it wouldn't be possible. Of course, as long as you're not doing any excessive (or any at all for that matter) 3D rendering at 2560*1440*2.

    Best of luck!

    Really? What type of monitors do you have, brands, both running at 2560x1600 resolution?

    How do you connect these two monitors to the rMBP?

    Could you post a screenshot?

    Would you be so kind to post some photos (or even make a youtube video if possible)?

    Two monitors connected to two separate VGA-MDP connectors, each connected into one Thunderbolt port.

    They're both Asus PB278Q, 2560x1440 each.

    MBPr with two external monitors

    Running two Samsung monitors at 1920x1080 connected through the MBPr thunderbolt ports with an adaptor thunderbolt to hdmi so i can connect both monitors.
    I cannot do 2560x1600 because my monitors won't allow it.
    But it handles them with no problem. Usually from 12 - 16 programs open at the same time.
    MBPr 15 inch 2.6 Ghz intel core 7, 8 GB Ram, 512mb SSD

    I realize this thread hasn't been active in a while, but I'm struggling to solve my problem... It looks like you have a VGA to Thunderbolt adapter, and with it your MBP is outputting 2560x1440, correct? My two displays are 2560x1600, and while I can use apps like QuickRes to "display" 2560x1600, it isn't crisp (clearly some sort of software upscaling). I've tried straight HDMI, Thunderbolt to HDMI, and Thunderbolt to DisplayPort, and in NONE of these does OSX give me any options above 1920x1080. It's almost as if it is unable to read the correct EDID data and thinks my displays are limited to 1080p. Is it possible that the VGA adapter is avoiding that issue by not reporting any EDID data at all? Would a Dual DVI (capable of 2560x1600) to Thunderbolt adapter accomplish the same task? And am I going to have the same issue when I go from a MBP to a Mac Pro?

    Displayport to mini-displayport should be your best bet, if your monitor supports it. Displayport is the best standard for 2560x1600 right now, as you don't need any expensive adapters.

    You said you tried displayport to mini-displayport already though, so I'm not sure what the issue is...but it is definitely a software issue.
