That was a pretty bad description.  Let me try again:

I got a gaming laptop.  Works great on it.  However, when I plug it into an external monitor via HDMI cable, and run AotS full-screen at the monitor's resolution (1920x1080), everything... shimmers?  From the opening intro to the main menu to in-game, it flickers, or shimmers, or... something weird.  Doesn't happen at lower resolutions, or at 1920x1080 windowed.

Messed with all the video options (free sync, vsync, etc.) to no avail.

Anyone seen this and/or know what it is?  Doesn't happen with any other game, at least that I've seen.
