Make sure that Picture Preset is set to “VIVID ” mode, “ Contrast ” bargraph is set to maximum
(100%) and “ Active BackLight ” is set to “ Off ”.
Ensure that TV is in Factory mode to access to ”White Balance” adjustment submenu , then
scroll down to toggle off “ Pic. Enhance ” flag.
PC VGA , CMP YPrPb , R GB , CVBS_PAL Gain/Offset matrix offsets locations are relative to
HDMI/DTV .
CVBS_SECAM and CVBS_NTSC Gain/Offset matrix offsets locations are relative to
CVBS_PAL.
Warm and Cool Tone are relatives to Normal mode.

“ Gain ” registers set need to be adjusted at 70IRE.
¾
“ Offsets ” registers set can be adjusted at 30IRE, but it’s not recommended to keep them
defaulted.
Note: All matrix offsets locations can be individually fine-tuned.

Targets and Tolerances for all inputs
The measured parameters should be mainly “ x ”, “ y ” coordinates.
The “ Y ” peak luminance measurement at 100IRE is depending on achievable panel
performance and less important than saturation on high light. If necessary, “ Scaling Contrast ”
register can be adjusted.
The “ BlackLevel ” measurement need to be within 1% ±2 . If necessary, “ Scaling Brightness ”
register can be adjusted.
The White Balance alignment should be performed using a well calibrated and contact less
analyzer (ex: Minolta CA210 or CA310). The analyzer may not touch the screen surface, and
measurement must be performed in a dark environment keeping the probe(s) at 90+/-2° from the
panel center.
The result should fulfill TCL matching specification (Minolta CA310 reference with CH00):
