Hi all

Im considering a new late rMBP 15" in the version without discrete GFX card - so only the Iris Pro. I am not interested in gaming, but for software development I usually work with 2 or 3 monitors at the same time.

Does anyone have any experience with the performance on this beast for handling 2 or up to 3 external monitors with Iris Pro only?

Thanks!
 
That isn't a problem not even if it is 4k monitors. That is all just pixels. Not an issue and only really limited by fixed function units in the GPU for which Intel specifically claims 3 display collage support (like eyefinity) and DP1.2 with enough bandwidth to handle it. That is all stuff they claim for the other GPUs too. Many monitors just isn't an issue for anything other than maybe transporting the display signal. Years ago much much slower GPUs could handle mulitple displays.
The only thing that can stress a GPU is what actually happens on those displays. Software development with IDEs doesn't ask for much from the GPU.

As long you're not using scaled mode, you should be fine.

What if I am using 1440x900 on the 13 inch retina with 2 displays both 16:9 27 inch (2600x1440) and 108p. If I put it "best for retina" with those 2 connected, it will be alright?
 
The iris pro will have no problem driving all those monitors at all. If you were trying to play a game at 2560x1440 then it might have some issue.. but that's all

I connected a 2560x1600 and a 1200x1600 with my Retina Macbook with 750m.
No lags, no problems. Also no problems with playing Skyrim at high settings on the external screen with 2560x1600.
