Hi guys (and maybe gals, it's hard to tell)... I have a question regarding gamma correction and calibration settings. I have this info from Monitor Asset Manager's Real-time EDID:

Color characteristics
Default color space...... Non-sRGB
Display gamma............ 2.50
Red chromaticity......... Rx 0.640 - Ry 0.340
Green chromaticity....... Gx 0.300 - Gy 0.690
Blue chromaticity........ Bx 0.138 - By 0.038
White point (default).... Wx 0.282 - Wy 0.297
Additional descriptors... None

I was wondering if any of this info can or should be used in the device calibration settings for gamma.... and if so, what should be the corresponding gamma correction settings?

I have tinkered with a calibration setting of pure power curve of 2.5 gamma and pure power curve 2.35 in the gamma correction... but I wasn't happy with the results. I have also tried other combos, and currently have both set at disabled (again not happy with the results). I don't have access to calibration gear, but thought maybe I could get better results if I understood what my TV's gamma is (pure pc, bt.709, etc. etc.) and what the target should be for gamma correction.

I have included screen shots of the two settings in question if there is any confusion about what I am talking about





Thanks in advance,

QB
