Hi There,

We work in support environment and use dual monitors setup. WIN7 heard to have very good support for such setup and easy to use functionalities. However at some point something which was great has gone troubled.

We can use both the monitors while working on it however just the time its locked it blacks out the second monitor background and screensavers set if any. I tried looking for any config changes but in vain. Looking out for answer to this here.

Thanking you in advance.

There is no built in way to change this functionality. **When locked, one screen will be black.**There may be some 3rd party software that may do this however it would not be supported by  Microsoft.

    HI

    the only way I know this can be done is to configure your multiple screens as one.

    this can be achived by using the drivers related to your graphics card.

    Nvidia use the nvidia surround tool

    AMD use the catalyst drivers and you set up an eyefinity display

    Intel you configure a collage display

    once this is done your lock screen appears on all displays

    hope this helps

    It would be great if MS could fix this... In the mean time the following AutoIT script will change monitor to "Clone" mode before locking the screen, and then back to Extended upon logging back in again. It goes a little way towards acheiving the desired effect.

    It can be improved, to e.g. save the location of all the windows before changing to Clone mode. (atm all windows stack up on the primary monitor). It's not at all ideal, just a fugly workaround a bug that never should have been introduced...

    The "Black" screen was especially irksome for me because I leave the gamma ramp inverted (With PowerStrip) so those extra monitor black screens becomes bright white.

    This script disables the Win-L Shortcut, and instead used Win-K (It does not look easily possible to override built-in shortcuts with AutoIt on Windows 7)

    This seems strange because during the preview builds it did do this.

    I had this running with both monitors running a slideshow in win 81 - so don't tell, that this function was not implemented in  any windows-version yet. I did NOT use any 3rd-party-software for that function. But for all who miss that: I think, DisplayFusion can help out and light up both monitors :-) OK, it's not freeware.
