    I have been running three external 1080p monitors from my late 2012 MBPr for years. It's starting to give out on me. I bought a Plugable USB-C Triple Display docking station to try with my 2015 12" MacBook. It worked, but the overall experience was terrible so I sent it back.

    Will the current model 13 inch MacBook Pro support three external 1080p monitors while in clamshell mode?


    I am aware that is officially supports two 4k monitors or one 5k monitor. I am also aware that the 15 inch MacBook Pro supports three monitors, but I am specifically shopping for a 13 inch laptop.

    Has anyone tried this? Or does anyone have any reason(s) why it should or should not work?

    3840x2160 (normally referred to as 4k) is the same amount of pixels as two 1080p screens. So a computer that can support two 4k screens should theoretically support at least 4 1080p screens

    Same pixels as four 1080p, actually, but I don't think it's only the number of pixels that matter.

    No. It's 4x the pixels of 1 1920x1080 display. But two 1920x1080 displays are also 4x the pixels of one 1920x1080 display.
    1920x1080x2=8.294.400 EDIT: I was being an idiot here - It's 4.147.200.
    3840x2160=8.294.400

    In terms of the video unit's capacity for handling it, it is pretty much all that matters. In terms of the I/O's capacity, it obviously isn't. However, seeing that the MacBook with a less extensive chipset can support it, I see no reason why the MBP shouldn't support the setup, with better performance (by a lot I'd imagine)

    Off by factor of 2.

    How embarrassing. I did actually miscalculate that. Sorry
