Acer P21 1 offers a convergence adjustment feature. To properly adjust convergence, it
is best to have an image that makes it easy to see any convergence error. A black
background with white letters or lines is recommended. When adjusting convergence,
look at the adjustment across the whole screen. When adjusting horizontal convergence,
look at the left and right edges of vertical lines or characters. When adjusting vertical
