I realize this thread has been dormant for a while, but hopefully some of you H79 owners are still out there.
I have an H79 which I would finally like to have professionally calibrated. I have an OPPO 980H (latest firmware) and a DirecTv HD DVR connected into an OPPO HDMI switch from which I have a cable going into the DVI input. That's the only input I'm using.
I see a number of old posts about the H79 losing calibration settings by defaulting from one setting to another. I realize it has something to do with PC-level RGB v. Video-level RGB, and some posters solved the problem with a Lumagen. I called OPPO to ask about this, and the rep said the OPPO's defaul is video-level (changeable via the Color Space Menu). He also said that he knew that with the H78 at least, some of the inputs were mislabeled, and perhaps that was part of the issue.
I don't fully understand the issue, but basically, I want to know whether I will be able to have the projector calibrated in a way that will "stick" without losing the settings and without having to purchase an expensive new piece of equipment. With all the accumulated experience on this issue, is there now a "best practice" I can tell the calibrator to follow to make sure this works out?
Many thanks in advance.
