    Automatically switch display w. HDMI device turned on?


    First situation now:

    I'm using a three display system where all displays are always connected but only max two can be used at the same time (see specs).

    Displays 1 and 2 are monitors, display 3 is a FullHD TV. I'm normally using 1 and 2. Display 3 is in my bedroom upstairs, connected with 15 meters or 45 foot HDMI cable. When I turn the TV on and choose PC as signal source, Windows 7 switches the playback device automatically from PC speakers to HDMI Audio Out, and back to PC speakers when TV is turned off or another signal source is selected.

    To choose which displays I want to use, I use Screen Resolution tool from desktop context menu.

    The Question:

    Would it be possible to make Windows switch displays automatically when I turn TV on? I mean do I have to always first change displays from Screen Resolution tool, or could it with some register manipulation be an automated process? And back when TV is turned off.

    Sound device can do it. Could I "teach" my video settings to do it, too?

    Thanks in advance,

    Kari

    See petrossa.com

    Is your TV connected via DVI-DVI, DVI-HDMI, HDMI-HDMI or other?

    There is a pin that feeds data from the TV to the card, so it is (in range of) possible.

    Finnish Translation:
    Maybe, maybe not.

    He can spec out how to connect the PC/TV to your dishwasher...

    He can probably do this.

    HDMI > HDMI. I think it should be possible. This is not a problem, it just would be last missing point in my almost automated system.

    Kari.

    P.S. You had wrong address. His blog is here.

    See this: Monitor Hot Plug Detection

    It means that the answer is Obama. Ask ChuckR or DJG.

    (Yes, we can).

    I can already translate Antman to Finnish, M$ is going to be a piece of cake.

    EDIT: The principle seems to be about the same how sound device is hot plugged, i.e. when I turn HDMI device on my sound output device is automatically switched.

    That's object-oriented stuff:

    As a rule, I only deal with hardware and software. I Repeat: and ...

    Edit:
    Ooopps, didn't read back far enough.
    Kari's post is serious query.
    Sorry, not familiar with HDMI cable/pinout/control signals, etc.
    Been sequestered way too long.
