1.OFFSET(26%) W/B ADJUSTMENT(This is only for AV/TV)：Change the input signal to 26% white level
performance .Set the CHROMA7120 to 288 301 30 and MODE_RGB ,then adjust the TV’s RB、GB、BB to make
CHROMA7120 display to 100.
2.W/B ADJUSTMENT (100%): Change the input signal to 100% white level performance. Set the
CHROMA7120 to 288 301 415 and MODE_RGB , then adjust the TV’s RG、GG、BG to make CHROMA7120 display
to 100.
3.Save the adjustment. Then change the input signal to 26% white level performance. Set the CHROMA7120 to
MODE_RGB and CH3, check whether the color temperature was in SPEC (color spec is x±15;y±15;Y±15). In this
time, most of the TV is in SPEC, while the others should be adjusted twice or more to make its color temperature in
SPEC.
4.CHECK CUT OFF: Change the input signal to 0% white level performance. Firstly, press the “brightness” from
50% to 0% and make sure the Y is not changed. Secondly, change the input signal to 32 GRAYS performance and
make sure the grays is not connected at any position.( as the 5% level is between the first gray and the second gray.
5%=（1/32）*1.6。)
1.The white color temperature in PC Mode should be app.7200K(CIE1931: x=0.303, y=0.319，Y>350),
10300K(CIE1931 : x= 0.278, y= 0.289, Y>350 ).
2.The white color temperature in AV/TV Mode should be app. 8700K(CIE1931:x=0.288±15, Y=0.301±15,
Y>370). In this Mode,we should check the black balance,which level is 26% of the white level(1.0Vpp).
3. The white color temperature in HDTV/HDMI Mode should be app. 8700K(CIE1931:x=0.288±15, Y=0.301±15,
Y>370)
Those three channels should be factory preset and not be possible to be modified.
The measurement position is the center of the display(5) at brightness set to center and
Contrast set to max. . The tolerance of the color coordinates should be less than ± 0.015
