characteristic
2. Set subcontrast data to maximum.
3. Set subaddress (1F) data to (04).
4. Set subaddress (1E) data to (01), and monitor pin 14. Determine blue stretch start point
BS_Pmin using the figure below.
5. Repeat the step 4 above by changing subaddress (1E) data to (04) and (07). Determine blue
stretch start point BS_PCNT and BS_Pmax.
6. Set subaddress (1E) data to (04).
7. Monitor pin 14 and calculate ratio of blue stretch ON gradient in relative to blue stretch OFF
gradient in decibel (BS_GCNT) using the figure below.
8. Repeat the step 7 above by changing subaddress (1F) data to (00) and (07). Calculate
gradient ratio in decibel (BS_Gmin and BS_Gmax).
Note: Calculate white-peak blue start point in IRE as setting positive amplitude at pedestal level
of output signal to 2.3 Vp-p = 100 IRE.
