    I just connected 1 external monitor via thunderbolt to vga but now i want more.

    I want to connect TWO ext. monitors, but I can't find any thunderbolt adapters that split into TWO VGA....

    anyway I can accomplish this? I love having big monitors. haha.

    You will need a USB to VGA DisplayLink adapter.

    Guys, if I use this....

    https://www.amazon.com/Thunderbolt-Benfei-Displayport-Converter-Warranty/dp/B013UULUL4

    WIll it work? So I can have two monitors...

    Also, will connecting more than one monitor slow things down on my computer, make things lag, etc?

    you may only use ONE port at any one time of that adaptor (I have one, plus under high Sierra they only work with DVI)

    in theory thunderbolt and a usb 3.0 to VGA should work.
    I have not tested this out though.

    That adapter will not work and it is not Thunderbolt, it is just Mdp. You will need a Thunderbolt 2 dock with 2 video outputs.

    As for performance, it depends what you want to do and the specs of the MBA.

    Aside from that, the Matrox device causes the OS to see the pair of them as a single (huge) display. For all practical deployments that means the two externals have to be contiguous, as in robvas's posted image above.

    You can't arrange your screens like this:

    [external monitor] [laptop TFT as primary display] [external monitor]

    Not quite useless but it wasn't a solution for me.

    edited to add: my computer is a vintage-2011 MacBook Pro not an Airbook, hence I have actual USB ports as well as a Thunderbolt. So I was able to use a USB DisplayLink adapter to get 3 screens.
