• If you are not sure which video level is correct, leave it at the default setting. Or, if the picture is
excessively dark or very washed out, try changing the HDMI output level to see which one looks
correct
Step 3: Calibrate the
black level
(brightness) of your display:
• Show the internal video test pattern
Black 1-3%
(under the OSD menu
System
and
Video Test Patterns
)
• Turn the
brightness
setting of your display down excessively so that the whole screen is black
• Turn the
brightness
up until you can barely see the difference of the 1%, 2%, and 3% bars
Step 4: Calibrate the
white level
(contrast or peak white level) of your display:
• Show the internal video test pattern
White 97-99%
• Turn the
contrast
setting of your display up excessively so that you see the whole image as white
• Turn the
contrast
down until you can barely see the difference between the 97%, 98%, and 99% bars
Step 5: Calibrate the
color balance
of your display:
• Show the internal video test pattern
Cross Gray Steps
, and pay attention
to the black bar and white (100 IRE) bar
• Adjust Red, Green, and/or Blue offset/bias settings of your display to fine
tune the color of the black bar if it doesn’t look a neutral black*
• Adjust Red, Green, and/or Blue gain settings of your display to fine tune
the color of white bar if it doesn’t look a neutral white*
*Aim to lower the color you see as dominant rather than increasing the other two
Step 6:
Repeat steps 3 to 5 until the brightness and contrast settings don’t need changing,
and the R/G/B offset and R/G/B gain settings of your display are satisfactory.
4.6.3.2 SOURCE VIDEO LEVEL AND COLOR CALIBRATION
Once you have calibrated your display for correct video output levels and color balance, you don’t need to
calibrate your video sources
if they also have correct video level and color balance
. In practice, however,
most of the video sources will still have some form of problem with video levels or color balance and we
have to calibrate them one by one for perfect results.
To calibrate video sources, we ideally need test patterns originating from the video source. This is
straightforward using readily available specialist calibration DVDs. Many HDTV stations also carry test material
at certain times of the day. In the absence of any specific test material it is difficult to calibrate accurately, as you
can only make the picture look how you expect it should be, so check several discs to gain a good balance.
Please follow the steps below for each video source connected to
