This model Mac, however, could ship with either an Intel Iris Pro 5200 (2.2 GHz) or NVIDIA GeForce GT 750M and Intel Iris Pro 5200 (2.5 and 2.8 GHz) graphics card. It can also run up to two 4K displays at 60Hz with the NVIDIA GeForce GT 750M graphics card. Officially, when using external displays, your Mac displays up to 2560 x 1600 pixels (when using Thunderbolt) or up to 3840 x 2160 pixels at 30Hz or 4096 x 2160 pixels at 24Hz (when using HDMI). The 15' Macbook Pro (Retina mid-2014) model will support a single-stream 4K (3840 x 2160) display at 60Hz so long as you are running OS X Yosemite v10.10.3 or later. Below is some info that may help you out. I have to admit your question confused me a little. All generally works okay but I get this odd split screen thing which stops the cursor from being as responsive and accurate. I bought the Dell UP2715k 5k monitor and connecting it to my MBP via two miniDP to DP cables. I know 'retina' is just a marketing term but thought I may as well use it as it's driving me insane. What are people's thoughts? I know you can do it with one cable now (based on reading!) but I have no idea if Apple/Dell are correct?Īlso. They also said I could use HDMI to Display Port too. I chatted with Dell and they suggested a Thunderbolt (or Mini Display Port) to Display Port which would allow for both audio/video and display as retina on the 5k.

I am wanting to connect them both together so on the 5k monitor it would downsample to show my retina resolution. It's video ports are as follows ( ): 1 Mini Display Port, 2 Display Ports. I'm going to be buying the Dell UP2715k 5k monitor. It has an HDMI port and 2 Thunderbolt2 ports. I have a 15' Macbook Pro Retina mid-2014.

It feels like even having long conversations with both Apple and Dell that I cannot get an answer to my question so let me try and figure this out.
