    Hey guys,

    I've been looking and looking and can't find the info I am after. Perhaps someone can help me.

    The specs on the early 2013 rMBP says that it supports two monitors upto 2560x1600 via thunderbolt, and doesn't say what the HDMI will do.

    I have found the LG 34UM95 monitor and have fallen in love with it. Has anyone tried it with the retina MBP early 2013 or earlier and got it to work? 3440x1440 sounds like a sweet resolution.

    I know it will work with the late 2013 model. But can you squeeze that resolution out from the one I have at a reasonable refresh rate?

    Thanks guys,

    For the benefit of others.

    Macbook Pro 15" Retina - Early 2013


    4k panel will run over thunderbolt / display port. But at 30Hz only. I have tried the entry level Asus panel.


    LG 34UM95 runs just fine at 60Hz. I have even played Team Fortress 2 at the native res with settings on low. The frame rate is map dependant, anything from 12 to 40 fps. But connecting this monitor causes the mac to switch to the Nvidia card and the fans switch on pretty quickly. There is a slight constants hum of fans coming from the mac when using the screen. A little quiet music drowns this right out.


    EDIT: after using an air duster to clean out the dust in my vents - its back to being a silent machine even with this display :D

    I also have an Early 2013 rMBP. According to the specs, the maximum external resolution is 2560 by 1600. What resolution are you running and how does it look?

    All the macbooks since 2012 have been able to 1440p without issue. You can use an HDMI or a minidisplayport to HDMI adapter in the thunderbolt port.

    1440 yes, however 3440 is not supported on 2012 and early 2013 models. I could not find information regarding success at that resolution, or a visual proof of 2560 x 1440 looking decent on a 34". I just settled with a new Apple Thunderbolt Display for $700 from eBay. Happy with it.

    I have a 34UC97 and a 2012 Mac Mini. The HD4000 in the mini struggles to push the res if I am honest. It also detects the display as a TV and runs at 50Hz.

    I connected a 15" MacBook Pro with the Iris Pro and it ran perfectly at 60Hz and was blazing fast.

    What GPU is in yours?

    My Early 2013 Retina MacBook Pro has both an onboard Intel HD4000 and discrete Nvidia GT650M. According to Apple, the max external resolution is 2560 x1600 for two displays. I didn't want to risk the possibility that a single display would not exceed the limitation.

    After all, I love the build of the Apple display and all my thunderbolt devices are 1st generation. I'll definitely use a least 2x the energy of a Samsung or LG, but it's bearable for now.
