Vista and external laptop monitor?

    I have an HP laptop and use an older external LCD monitor. The monitor
    works fine... as long as the laptop lid is open but goes blank and says
    "mode not supported" if I close the lid. I have the laptop settings (Vista)
    to "do nothing " when I close the lid. Might I have another setting that is
    off somewhere?

    Thanks... Bob

    In the Vista Power Options menus you can tell it not to, it used to, it do
    this way.

  4. It probably depends to some extent on your graphics chip & driver.

    My laptop (a Dell D630) has an nvidia graphics chip. I use it in a
    docking bay (actually it's the little one - I think they just call it
    a port adapter), which has 2 video out connectors, each of which is
    connected to a monitor.

    In my power settings, I make sure that it's set to "Do nothing" when
    the lid is closed and the power is plugged in (make sure you haven't
    just set it to do nothing when you close the lid when it's on
    battery).

    Then I configure the displays using the NVidia Control panel software
    - when the laptop isn't docked, the software recognises that, and only
    gives me the laptop screen to configure, but when it is docked, I can
    configure the external monitors. It might be that you have to connect
    your external monitor, leave the laptop open, configure the display
    settings, and then close your laptop. Hopefully the machine should
    then remember these settings (the NVidia software does a reasonable
    job of this but tends to forget which monitor is in which position).

    One more thing - some laptops have a setting in the BIOS which
    determines which screen has priority. If you have it set to use the
    laptop screen as the primary one, then perhaps your machine is
    selecting that, but turning it off because the lid is shut.

    Could it be the monitor? I was using one that worked fine.

  6. Solution: change video mode to a lower res still supported by the TV.
    Then change back to your higher res mode but do not apply changes. Tab
    until the APPLY button is highlighed. Close the laptop lid such that the
    TV goes blank. Press enter on the keyboard to apply new video mode. TV
    should pop on and you can accept the new video mode.

    Hope this helps, jaga
