4 Alignment and Adjustments
4-2-4 (c) HORIZONTAL POSITION ADJUSTMENT
CONDITIONS
Scanning frequency: 68 KHz/85 Hz
Display image: Crosshatch pattern
Use control bar after selecting “H-POSITION” in
left menu to center the horizontal image on the
raster.
4-2-4 (d) VERTICAL POSITION ADJUSTMENT
CONDITIONS
Scanning frequency: 68 KHz/85 Hz
Display image: Crosshatch pattern
Use control bar after selecting “V-POSITION” in
left menu to center the vertical image on the
raster.
4-2-5 Linearity
Linearity affects the symmetry of images as they
appear on the screen. Unless each row or column
of blocks in a crosshatch pattern is of equal size,
or within the tolerances shown in Table 4-2, an
image appears distorted, elongated or squashed.
Horizontal Linearity = 2x x100
Vertical Linearity = 2x x100
Table 4-2
❈ Preset Mode : 68 KHz / 85 Hz
Pre-load Mode : Refer to Timing Chart
4-2-5 (a) HORIZONTAL LINEARITY ADJUSTMENT
CONDITIONS
Scanning frequency: 68 KHz/85 Hz
Display image: Crosshatch pattern
Brightness: Maximum
Contrast: Maximum
To adjust Horizontal Linearity, refer to Table 4-2
for the tolerance range.
Increase or decrease H_LIN to optimize the
image.
4-2-5 (b) VERTICAL LINEARITY ADJUSTMENT
CONDITIONS
Scanning frequency: 68 KHz/85 Hz
Display image: Crosshatch pattern
Brightness: Maximum
Contrast: Maximum
To adjust the Vertical Linearity, refer to Table 4-2
for the tolerance range.
Use control bar after selecting “V-LINEARITY
BAL” in left menu to optimize the image.
