Aspect Ratio 
Switches the scaling method between Full Scaling and Maintain Aspect Ratio 
Default: Full Scaling 
Full Scaling – scales the X- and Y-dimensions of the input video (up or down as 
needed) to the display’s native resolution. 
Fill To Aspect Ratio – Assuming a landscape orientation and an input video with aspect 
ratio smaller than 1024 x 768 for the 15-inch or 1280 x 1024 for the 17-inch, scales the 
Y-dimension of the input video (up or down as needed) to the display’s Y-resolution, 
and scales the X-dimension to maintain the input video’s aspect ratio (and fills the rest
of the display with equal black bars on the left and right). 
The touchscreen may need recalibration when switching between Aspect Ratio 
options.
