2-2 WHITE Balance Coordinates
2-2-1 HP-P3761 White Balance Adjustment
1. W/B Adjustment is required for the following five modes :
DVI →Component(720p) →Component(1080i) →VIDEO (Video port) →VIDEO (Graphic port)
2. Adjustment Method (Signal equipment : MSPG-925LTH, Measurement equipment : CA210)
■MSPG-925LTH
Equipment that outputs analog and digital signals simultaneously
(Analog / Digital signal output / TV signal output (S-Video included) / HDTV signal output)
-. Digital Serial : TMDS (DVI24, SiI160) + DVI-I (Analog, Digital)
-. Monitor Signal (Analog): R, G, B, HS, VS, CS
-. TV Signal (CVBS) : NTSC M, NTSC J (7.5 IRE On/Off) (BNC or RCA), PAL B, D, G, H, I, PAL M, Nc
-. D-TV Signal (1080i, 720p, 480p)
♣
♣MSPG-925 is used to adjust the W/B.
■CA210 : Color Analyzers adjusting brightness, chromaticity and etc.
-. R.G.B monochrome correction, brightness and gamma character adjustment
-. White Balance and flickering measurement
(a) DVI
1) Input Toshiba Pattern at 720p resolution using MSPG-925LTH (model:#6, pattern:#16).
2) These are the point of measurement using CA210.
3) Press "MUTE-1-8-2-POWER ON" to enter the factory mode.
4) Change to "'DVI" Mode to key in "SOURCE" button.
5) Select "01.Picture Improvement" →"01.White Balance"
6) Keep the value of Y as adjusting "07.Sub Contrast(for HIGH)" & "08.Sub Brightness(for LOW)".
7) Keep the coordinate value of x and y as adjusting the value of R,G,B.
Adjust the coordinate x as the value of Red, and the coordinate y as the value of Blue.
<※Generally, the value of Green is fixed.>
-. Adjust the value of "Drive(01~03)" as the high point and the value of "Cutoff(04~06)" as low point.
-. the Y,x and y data refer to the "White Balance Coordinates by Mode" table on page 2-4.
(b) Component
1) Input Toshiba Pattern at 720p resolution (model:#6, pattern:#16).
2) Change to "COMPONENT1" Mode to key in "SOURCE" button.
3) Select "01.Picture Improvement" →"01.White Balance".
4) Adjust White Balance by selecting and adjusting Items 01. - 08. as performed in DVI mode.
5) Change input to Toshiba Pattern at 1080i resolution (model:#5, pattern:#16).
6) Adjust White Balance by selecting and adjusting Items 01. - 08. as performed in DVI mode.

adjustment should be performed with Video port and Graphic port separately.
1) Input Toshiba Pattern to Video Input (model:#2, pattern:#16).
2) Change to "'AV1" Mode to key in "SOURCE" button.
3) Select "04.Option-1" →"10.Video Port."
4) Set "10. Video Port" equal to "Video".
