Horizontal Position
Use or to adjust the projected image’s horizontal position.
If the projected image is not at the center of the screen (i.e. shifted to right or left) and ends up being cropped, use this
function to adjust the image’s horizontal position.The following image is an example of test image from an external signal
source:
Native picture Skewed left
Skewed right
Vertical Position
Use or to adjust the projected image’s vertical position.
If the projected image is not at the center of the screen (i.e. shifted up or down) and ends up being cropped, use this function
to adjust the image’s vertical position.The following image is an example of test image from an external signal source:

It is recommended that when adjusting the image, the horizontal total should be adjusted before the
horizontal phase. However, if the image still flickers even after you have adjusted both, try lowering the
image noise.
Frequency
Use or to adjust the projected image’s phase.
Use this function to adjust the phase of pixel sampling clock (relative to input signal). Should the image still flicker or show
noise (i.e. edges on texts) after optimization, adjust phase accordingly.
