    Guys, i just received my M11X 4 days ago and yesterday i wanna tried out on my Sony 32EX400 LCD through HDMI.
    However when i switch it to the external LCD using 1920x1080p, it doesn't extend properly as it feels like it zoom for 120% on the screen which makes the edge stretched outside the screen.
    Example: My Computer was at the top left of my M11x default screen, when i switch to external, it will be gone as it's out of the screen.

    Hope to get some help and thanks :D

    What happens when you tell it to just use the monitor rather than extend?

    What you are experiencing is called Overscan. There are two possible places where this behavior is happening:

    1) The most likely reason is beacuse your TV is set to image stretch. I am not familiar with your particular TV make/model, but look for settings that have terms along the lines of : Image Stretch, Widescreen/Normal, Aspect Ratio, 16:9, etc. Somewhere, there is likely a setting where your TV is stretching your image. Turn that off.


    2) Or, less likely, it could be some weird PC setting. On your PC, right-click on the Desktop and go to Graphics Options --> Output To --> Extended Desktop --> Built-in Display + Digital TV.

    Then right-click on your Desktop again, and go to Graphics Properties --> Display --> General Settings. Change the "Display: Digital Television", and set your resolution for your HDTV to be 1920x1080.

    In the same Graphics Properties utility, go to Display --> Custom Resolutions. Choose "Display: Digital Television". Make sure that the slider for "Underscan Percentage" is set to 0, or that the radio button up top for "Basic Settings" is checked.
