No- cnet picture settings for NX720 and hx929 are not for HX820, at least not for my Sony. I bought the calibration disk cnet recommends so ill let you know the pic settings i come up wiith once i have free time to do it after finals. Howver, i heard each tv/room that its in- has its own quirks so mine will not necessarily be great or you. But ill still let you know. If you already figured the pic settings, please share.
Is the Sony Bravia HX820 picture settings the same as the NX720? The owners manual I have is for both.
