-     *    3 - controller supports hardware stereoscopic signalling
+     *    3 - controller supports hardware stereoscopic signaling
      *    4 - =0 stereo signalling via external VESA stereo connector
      *        =1 stereo signalling via VESA EVC connector

Why are you changing 'signalling' to 'signaling' in one place, but 
leaving it as is twice two lines down. Note that I'm not sure which form 
is right, but ispell is happy with both so it's possible both are ok.
