    Hello All,
    Although HM77 Chipset + INTEL HD4000 Support 3 Independent Displays,
    I was never able to achieve Notebook Screen + 2 External (I tried all configurations - DIPLAYPORT/HDMI/DVI).
    I also know that 3 displays are working just fine over Linux (170EM) which means it is technically possible.
    I guess this is a driver related problem.
    Anyone got some info about that?

    Origin (CLEVO) 170EM | 3820QM | 16GB 1600MHZ | GTX680m | 64GB M4 SSD + 256GB M4 SSD

    The thing with most video cards is how they are set up they can only support 2 Digital displays at a time, or 2 analog. I read about it a long time ago.

    Then with the drivers in order to run 3 you need to have all 3 the same but that was across 2 cards.

    This is why eyefinity cards have DP. Its capable of supporting more than 2 displays per card with DP.


    I think it might have something to do with the pixel clock.

    I had thought that Clevo limited it to two displays on the EM models, regardless of the chipset or video card used. So either laptop + external, or two externals; I don't remember where I ran across that, and the user manual did not give a definite answer. You can try Fn+F7 and/or Windows Key+P to switch through the available display options that it will allow. Not sure why it works in Linux, must be some kind of driver or BIOS thing that is being bypassed.
