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 phosphors
and line them up properly in order to produce pure color. Displayed characters
and images may appear fuzzy or have tinges of red , green, or blue if the electron
beams do not converge correctly.
The 2115E monitor provides a convergence adjustment. To properly adjust
convergence, it is best to have an image that makes it easy to see any conver-
gence 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 verti-
cal lines or characters. When adjusting vertical convergence, look at the top and
bottom edges of horizontal 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.
