    Multiple Display Expectations of HD Graphics 630


      I wish to run three monitors using my newly acquired Acer Aspire TC-780A with 8GB of RAM, with the onboard Intel HD Graphics 630 processor . I have updated the driver and have run the Intel diagnostics with nor error messages resulting. The monitors have DVI and VGA ports. I can satisfactorily run two monitors at a time, using various configurations, but cannot run all three..  The two monitor configurations I can run are:


      Setup 1) Monitor 1 connected to the PC using a DVI to HDMI cable, connecting to the HDMI port of the PC.  Monitor 2 is not connected, but is attached to a KVM switch accessing other PCs.  Monitor 3 is connected via a DisplayLink adapter from the DVI port to USB on the PC.  This setup operates satisfactorily, except that I cannot use Monitor 2 (my main monitor) with the Acer PC.


      Setup 2)  Monitor 1 is not connected to anything.  Monitor 2 is connected to the Acer PC through the KVM switch, using VGA.  Monitor 3 is connected via the DiskpalyLink adapter from the DVI port to a USB port.  This arrangement also works satisfactorily but Monitor 1 is not used at all, making it a waste of wall space. 


      The setup that I desire, but does not work is: Monitor 1 is connected to the Acer PC via the DVI to HDMI cable.

      Monitor 2 is connected via the KVM switch, using VGA.

      Monitor 3 is connected using the DisplayLink adapter from DVI to USB.

      Essentially Setup 3 is the same as Setup 2 except that Monitor 1 is connected to the HDMI port.

      If I plug Monitor 1 into the HDMI port while the system is running, the monitor is recognized and an appropriate display occurs, including identification in the display settings.  However, I cannot move my cursor into Monitor 1's screen.  If I reboot, then the display of Monitor 1 us garbled, with horizontal lines and portions of the expected display showing.  The monitor is completely useless.


      Hence my question: I am expecting too much from this graphics processor?  If I am expecting too much, what board would you recommend?  I have run a similar configuration from an older low-powered laptop over 7 years old with less RAM  that did this great!


      Any help or comments will be appreciated!
