Video looks squished (VGA sources only)
The image is squeezed horizontally on the screen. This distortion occurs when there's a mismatch between the
aspect ratio the Standalone VGA Grid detects and the aspect ratio that is sent from the source signal. To
compare the two signal values, you must know the aspect ratio that the source is sending.
