    Hi folks.

    I have a weird problem with my thinkpad t420.
    I dropped it recently and i must have damaged something i'm just not sure what.
    When i boot up the bios displays just fine and when i log into win 7 the screen just gets super distorted.
    So i figured it was a bad screen.I replaced the screen and the problem still exists.
    But the strange thing is that when i plug in an hdmi cable it works fine .
    And i mean the laptop display works.Also the external screen works but even with the hdmi cable only plugged into the laptop and not into te monitor it still works.Does anybody have a suggestion please.

    Thanks Marien
