Measure the level of the output signal
amplitude Vout when a 0.7Vp-p video
signal is input.
Contrast = FF/DRIVE = 00
Measure the OSD level of the output signal
when the OSD pulse is input.
GOSD1: OSD = FF/DRIVE = FF
GOSD2: OSD = 00/DRIVE = FF
Calculate the difference in the data obtained
in No.9 between the channels.
Measure the black level of the RGB output
signal.
VBRT1: Brightness = 00
VBRT2: Brightness = FF
Calculate the difference in the data obtained
in No.11 between the channels.
