    Does the GPU support 3x monitors?
    If it does then yes, you just need the cables and 3x monitors.

    I have a 4,1 Flashed to 5,1 and am running a Radeon RX 560 with three monitors. They are lower res monitors only 1680 x 1050 but all three work just fine.

    There's probably a logical limit to how many displays macOS can support, but in practice you're just limited by the outputs of your graphics card(s). Lots of people run 6 monitors on two double-height graphics cards, or 9 monitors on three single-height graphics cards.

    You can even split a single graphics card output to two or three monitors using a box like the Matrox TripleHead2Go.

    Or get a WX series card that is actually designed to handle multiple monitors, rather than guessing with a gaming card.

    Sure... if you have a need for a workstation-class graphics card and you have the cash to spend. But I'm not sure that using a "gaming" card with multiple monitors is "guessing." All the gaming cards I've ever used have supported multiple monitors.

    The OP wants to run 3 monitors - getting a card that is designed to run 4 makes it easier. Running a cMP in 2019 means guessing which PC cards will work (See: all of the threads arguing of which video card will run with what)

    AFA cost - get a WX4100 they run for about $160 (Have a 10 year warranty and draw a whole lot less power.) That is the cost of better binning.

    WX4100 lists maximum digital resolution as 5120x2880. Is that per port or total across the ports?
