I'm wondering if anyone can explain a phenomenon I have observed when trying to calibrate my JVC G-15 projector with Avia.


I was Avia-calibrating a new DVD player today, which is mated with a Rock+ and the G-15. When I use Avia and calibrate the colors according the Avia disk, the picture appears somewhat washed out or pale in terms of coloration. In fact, my saturations on the Rock+ were around the 115 to 120 range, which I believe is quite a bit below the default (which I seem to recall as being 140). When I pump up the saturation to what looks good to my eye, it is around the 150 level.


I also observed this phenomenon with the Quadscan Elite to a much greater degree. When I calibrated with Avia using the Quadscan, the picture was pitiful as far as color saturation. I had to pump it up quite a bit to get it to look right.


When I calibrate with Avia just using the DVD player's progressive output into the G-15, on the other hand, the picutre looks fine. In fact, it looks like what the picture on the Rock+ looks like when I pump up the saturation a tad.


Why is it that the calibration with Avia while using a video processor seems to result in a picture that is washed out, while this does not happen with the DVD player being fed straight into the projector? Has anybody else notice this, or am I doing something really wrong?

When you calibrated with Rock+ in circuit, what is scaler output scan rate?

I now have the Rock+ set to output 48hz, but the results I believe were similar with 75.1hz.

Okay, but I meant the horizontal rate - 480p/720p/etc. I was going to say simply, the projector might be seeing a different scan rate and working from a different configuration memory compared to the progressive DVD at [email protected]
