Convergence
Horizontal & Vertical Convergence adjustment
Hor. Convergence: adjusts Horizontal Convergence
Ver. Convergence: adjusts Vertical Convergence
Convergence is the monitor's ability to precisely illuminate specific phos-
phors and line them up properly in order to produce pure color. Displayed char-
acters and images may appear fuzzy or have tinges of red , green, or blue if the
electron beams do not converge correctly.
Benq P211 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 convergence, look at the top and bottom edges of hori-
zontal lines or characters. The monitor is properly adjusted when the effects of
red and blue tinges are minimized.
The convergence adjustment adjusts the entire screen. It is not
possible to limit adjustment to specific screen areas.
