如果有gamma set就用gamma set
無就用brightness同contrast set
不過要留意i1同Spyder 3TV配合HCFR度LED TV係唔準的
有問題打畀我啦

From what I saw in your gamma graph, it seems like your Sharp TV still has some dynamic control being enabled which affected the on-screen gamma, e.g. dynamic contrast, dynamic backlight, local dimming, etc. You must turn them off before calibration. Otherwise, you will never be able to measure and calibrate the gamma (grayscale may be fine; but absolutely not for gamma).
I have no experience on your Sharp TV; and don't know what gamma controls that it offer to you. If it is labelled as "Gamma 2.2", "Gamma 2.3", etc. it can only serve as a reference for calibrating the gamma. Choosing "Gamma 2.2" doesn't mean that it will re-produce a 2.2 gamma curve for your TV. You must use the Eye One to measure it to confirm. Sometimes, esp. in projector, a "Gamma 2.2" preset will in fact average to a 2.1 gamma (for that particular machine and environment), a "Gamma 2.3" preset will in fact average to a 2.2 gamma, ... something like that.
And the last thing about gamma - it is more important to observe the "trend" rather than the average value. You can get an average value of 2.2 but the gamma curve may be so uneven that the 9-point gamma values can rise from 1.8@10% to 2.7@90%.
For AE3000, I don't think it has 9-point gamma adjustment. The feature was added starting from AE4000.
