    Laptop not recognizing external monitor - SOLVED
    « on: September 28, 2009, 08:13:24 AM »
    I have a working LCD monitor and am trying to get my laptop to recognize it.  I go through all te set up steps properly.  F7 is the toggle and all I get is a blank screen on the external monitor (the power light is green).

    I updated the driver.  No help there.

    If I go to  display devices via XP, I see the second monitor.  If I click "extend..." then a mesage flickers on the display which reads "Analog 1 cannot display in this video mode".

    Any help appreciated

      Lenovo X300 Laptop and a Dell standared issue 17" LCD (non widescreen).

      I confirmed that I have display adapters for both devices.  I have updated the video driver.  I have confirmed the resolution support is up to 1280X1024.  I have tried lower registrations as well.

        The laptop does support this.  I've tried the external monitor as the primary device (not in extend mode) and still no luck.

        can't be this hard

        Screen Resolutions
        X300=1440x900 which is 16:9 (wide screen)
        17"monitor= 1280x1024 which 4:3 (non-wide screen)

        These resolutions are not compatible.  Both must be 16:9 or 4:3.
