2. Linearity Adjustment
2-1. Horizontal Linearity Adjustment
* Hereunder integrate is done when value of control former "H.LINEARITY 1:60" and "H.LINEARITY 2:180"
come off the value of standardized.
1) Receive signal 23.
2) Open Menu (S), TAG2 "H.POSITION" and adjust "+", "-" SW so that the picture is centered with in the
screen.
3) Open Menu (S), TAG2 "H.SIZE" and adjust "+" SW so that the horizontal size is 396±3 mm. If not able to
set horizontal size, open Menu (S), TAG1 "H.SIZE MAX 2", adjust the horizontal size is 396 mm. After,
Data on "H.SIZE" adjusted to the maximum (255).
4) Open Menu (S), TAG1 "H.LINEARITY 2" and adjusted so that the horizontal direction width of the second
square may become the same from both ends of the screen.
Note: When a OSM Menu is hidden temporarily for picture adjustment, push "PROCEED " SW once to
display OSM Menu.
5) Receive signal 17.
6) Open Menu (S), TAG2 "H.POSITION" and adjust "+", "-" SW so that the picture is centered with in the
screen.
7) Open Menu (S), TAG2 "H.SIZE" and adjust "+" SW so that the horizontal size is 396±3 mm. If not able to
set horizontal size, open Menu (S), TAG1 "H.SIZE MAX 1", adjust the vertical size is 396 mm. After, Data
on "H.SIZE" adjusted to the maximum (255).
8) Open Menu (S), TAG1 "H.LINEARITY 1" and adjusted so that the horizontal direction width of the second
square may become the same from both ends of the screen.
Note: When a OSM Menu is hidden temporarily for picture adjustment, push "PROCEED " SW once to
display OSM Menu.
9) Push "EXIT" SW.
2-2. Vertical Linearity Adjustment
1) Receive signal 22.
2) Open Menu (S), TAG2 "V.POSITION" and adjust "+", "-" SW so that the picture is centered with in the
screen.
3) Open Menu (S), TAG2 "V.SIZE" and adjust "+" SW so that the vertical size is 297±3 mm. If not able to set
vertical size, open Menu (S), TAG2 "V.SIZE MAX", adjust the vertical size is 297±3 mm. After open Menu
(S), TAG2 "V.SIZE" so that the data is max (255).
4) Open Menu (S), TAG2 "V.LINEARITY" and adjust "+", "-" SW to make size of top square and bottom
square on the screen equal vertically.
Note: When a OSM Menu is hidden temporarily for picture adjustment, push "PROCEED " SW once to
display OSM Menu.
5) Open Menu (S) TAG2 "V.LIN.BALANCE" and adjust "+", "-" SW to make size of top square and bottom
square on the screen equal vertically.
6) Open Menu (S) TAG2 "V.LINEARITY" again and adjust "+", "-" SW to make size of top square and center
square on the screen equal vertically.
7) Make sure that the linearity of top, center, and bottom on the screen are ±3%.
8) Push "EXIT" SW.
