image in its native 16:9 aspect ratio. The image will

Size
"Size" controls both the image width and height in tandem, maintaining the current
aspect ratio (proportion) of the displayed signal data.

Vertical Stretch

"Vertical Stretch" adjusts the height of the image while keeping the width constant.
Use "Vertical Stretch" to change the aspect ratio of the display.
Pixel Track
Steady flickering or several soft vertical stripes or bands across the entire image
indicates poor pixel tracking. Proper pixel tracking helps ensure that the image quality
is consistent across the screen, the aspect ratio is maintained, and that the pixel phase
can be optimized (described below). Tracking determines the frequency of the pixel-
sampling clock, indicated by the number of incoming pixels per line, so that all pixels
generated by a particular source are sampled.
