• If data for an item cannot be obtained during Standby mode, the return data for that item will be "∗."
• The types of data for Items 1-3 in the table (drive sequence, standard/nonstandard, and type of ABL/WB tables) are the
same as with the command QPW.
• Each total value for Items 4-11 represents that of panel WB, user WB, and degradation correction, and the actual data being
sent to the ASTRA are output.
• Detection of V frequency: The V signal input to the panel is measured in the range of 30.51 to 99.99 Hz. The measured
value is multiplied by 100 and then output.
• Number of SUS pulses : The number is calculated from data from APL and the drive sequence. The output value must be
between 0174 and 2752.
• APL value: The APL value for the input video signal (or mask indication) will be output in the range of 0000 to 1023.
