Image Settings - Display - Clock
Adjust the horizontal frequency (clock) of the analog signal to improve visibility of the entire
image. When it is adjusted, you will notice that the image will appear to be stretched and
might in some situations start to flicker/scroll, at which point you must reverse the last
adjustment to stop it from flickering/scrolling anymore. This function can be used for older
signals that is not automatically detected by the internal display controller.
To adjust the Clock and Phase to a optimal setting it is recommended to display a image with
alternating white and black lines by stepped by 1 pixels either vertically or horizontally. It is
suggested to use a dedicated and external test pattern while adjusting.

Image Settings - Display - Phase
Fine tune the data sampling position of the signal (impacts on image quality). This function
will remove small transparent defects in typical characters where a portion seems to be more
faint then the nearby black pixels. The faint pixels are always visible as a line from top to
bottom (vertically). Note that this function is automatic and does not allow for manual values.
It is suggested to use a dedicated and external test pattern while adjusting.
