ITC222 Geometry & Convergence Procedures

V-Linearity
Adjusts raster Vertical linearity. Caution! Changing linearity too much also affects
vertical position. If linearity is close, this should not be adjusted. If it is not,
monitor vertical position and amplitude making certain the vertical size is still
correct and location is centered.
Vertical Linearity
H-Position
Adjusts the right/left video location on the raster. Since this affects video rather
than raster, it should not be adjusted until geometry and convergence are
completed.
Horizontal Position
H-Amplitude
Adjusts the raster width. Refer to the example screen. The outermost pattern
lines should be about 1/2” from the frame. If the raster cannot be perfectly
centered it should always be closer to the left than the right.
