4 Vertical
geometry for
NTSC system
(Key 1)
HITS(11)
VP60(02)
VLIS(0A)
VSS(08)
VBLK(00)
VCEN(1C)
OSDHS(1D)
DPC43S(00)
DPC169S(00)
Input a NTSC
cross hatch
pattern.
z
Adjust HITS for vertical amplitude.
z
Adjust VP60 for vertical position.
z
Adjust VLINS for vertical linearity.
z
Adjust VSS for vertical S-correction
z
(normally use default value)
z
Adjust VCEN for vertical position.
z
Adjust OSDHS for OSD position
z
Same as DPC, adjust it on EXPAND 4:3
mode and 16:9 mode.
5 Horizontal
geometry for
PAL system
(Key 2)
HPOS(0C)
DPC(23)
KEY(20)
WID(22)
ECCT(09)
ECCB(0A)
VEHT(04)
HEHT(04)
Input a PAL cross
hatch pattern with
black and white
background.
z
Adjust HPOS for horizontal position.
z
Adjust DPC, KEY, ECCT and ECCB until
the vertical line at left and right side of the
picture become straight.
z
Adjust WID for horizontal width.
z
VEHT and HENT is for the picture size
stability when changing the brightness of
the screen. Receive pattern of cross hatch
with black background and then change to
white background, then compare the
vertical and horizontal size between black
and white background. Adjust VEHT and
HEHT until you get the minimum
difference of screen size. After you adjust
VEHT and HEHT, you must re-adjust
vertical and horizontal amplitude.
6 Horizontal
geometry for
NTSC system
(Key 2)
HPS (10)
DPCS(1F)
KEYS(1F)
WIDS(22)
ECCTS(0E)
ECCBS(10)
VEHTS(04)
HEHTS(04)
Input a NTSC
cross hatch
pattern with black
and white
background.
z
Adjust HPS for horizontal position.
z
Adjust DPCS, KEYS, ECCTS and
ECCBS until the vertical line at left and
right side of the picture become straight.
z
Adjust WIDS for horizontal width.
z
Adjust VEHTS and HEHTS using same
method of PAL system. Also need
re-adjustment of vertical and horizontal
amplitude.
