    Windows 8.1


    Tried to install the 64 bit version and it says "The driver being installed is not validated for this computer. Please obtain the appropriate driver from the computer manufacturer."

    What happens if you press the Windows Logo key + P and then select "Extend". I seem to remember somebody saying that on some of these all in ones, you can actually feed a signal in and display it on the screen like you do on a TV. If that's true I would double check that the HDMI port your connected to is in fact a signal out jack, not a signal in jack.

    You don't need a latest driver. Mine is Windows 8.1, HD 4600 integrated graphics, driver is over a year old and the HDMI output is fine into a TV used as a monitor. Cloned, Extended Desktop, etc all works fine.

    I would physically check the condition of the HDMI socket, and/or try a different HDMI lead. Just to eliminate possibilities there.

    However just looking at some HP AIOs, it seems that some don't have an HDMI video output at all. You will have to check.

    All I do (on a Laptop) is just Right Click on the Desktop for the Intel HD Graphics Control Panel > Display > Display V > Multiple Displays > etc.
    You can save a particular profile for multiple displays if you wish.
    The Charms Bar Apps stuff also works if you want that route.
