rMBP early 2013

After the Mavericks updates (10.9.3 and .4) macbook's with the nVidia 750m can run on 4K displays @ 60Hz

Since the early 2013 model doesn't have the 750m but the (1GB) 650m i think the max i can run is 4K @ 30Hz (with or without third-party apps to force the res.)

Could anyone confirm my model can't go higher than 30Hz?

 

Thanks in advance!

Hello MattTheMedic,

 

Thanks for using Apple Support Communities.

 

Please see the following article for more information concerning the use of 4K displays with your Mac.

Take care,

Alex H.

Thanks for your reaction.

I already saw the article.

It doesn't mention a Macbook before late 2013.

I guess that means i can't run it with an ''older'' mac.

From MacBook Pro (Retina, 15-inch, Early 2013) - Technical Specifications

 

Graphics and Video Support

  • Intel HD Graphics 4000
  • NVIDIA GeForce GT 650M with 1GB of GDDR5 memory and automatic graphics switching
  • 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

That suggests that i won't we able to even run 4K @ 30hz.

 

(this might be a stupid question but does it make any difference if i use clamshell mode?)

No, opening the clamshell or closing it makes no difference. Typically, Apple does not provide newer firmware which may be able to enable features that were hidden. The only one I can recall is the 802.11n capability, which was enabled with software, because the radio already had it.

It can, i have a mbpro 2013 early model, you need this stuff https://www.amazon.co.uk/Mini-DisplayPort-HDMI-Active-Adapter/dp/B01B702YTG/ref= sr_1_3?ie=UTF8&qid=1467806484&sr=8-3&key… and sreenresx.  Will run on 60hz 4k.

I have done as you say. I bought the cable but it does not work.

 

I can only run 4K at 30hz or 2560x1600 at 60hz.

 

I am on a early Macbook Pro 2013 with dual Intel and 650M Nvidia card.

 

Help!

You need to also use SwitchResX to force the 4K resolution and 60Hz refresh rate. Download: https://www.madrau.com

Hey man were you able to resolve this?
