This is a question for those of you experienced with HTPCs.
As some of you are probably aware, the Bravo D1 has new firmware avaliable which allows setting up a custom output resolution to match your PJ, useful for those who's displays don't match an industry standard TV def. Mine is 1366 x 768.
I began by inputting a set of values someone was using in powerstrip for the same PJ I have in an HTPC, I believe in Powerstrip. While he had these values working with he PJ (Sanyo PLV70), as posted they did not work with the D1 (screen was scrambled). Horizontal frequency was 56.159, and all other values listed below were as shown.
I played around with several of the parameter. I understand the function of several of them at a basic level, but not nwell and do not understand what effect altering most of them will show in the image. I finally got an image with the settings below. The image appears for values of HFreq from 44 up to about 53-54. I am running it as show below.
Hfreq - 52060
Vfreq - 72020
Horiz res - 1366
Vert res - 768
HSync total - 1784
PreHSync - 80
HSyncActive - 136
PostHSync - 208
VSync total - 780
PreVSync - 01
VSyncActive - 2
PostVSync - 10
HSync Polarity - +1
VSync Polarity - +1
First thing, it seems odd the PJ would reject the same signal it accepts from an HTPC unless A) differences in individual PJs or B) D1 generates signal with dfferences from HTPC, even with same parameters set.
Any way, now to my problem and question. In comparing the picture at 1366x768 vs. the D1's standard 720p and 1080i output options I see the following:
On custom, pans across vertically lined images seem to jerk a little. Likewise, while watching TTT, there seems to be a fairly slight jerkiness to CGI generated images, almost giving them an appearance of old stop motion. On the other settings, this does not occur.
Plainly, one of my parameters above is set less than optimally. Since while the image detail is as good or better at my PJs native rez, this is really distracting and I prefer using another setting even with the dual scaling going on.
So can one of you help with one or more of the following:
Point me in a good direction to get specifics on the function and effect of the above parameters on a video image;
Let me know which of the above parameters might be adjusted to minimize the effect describe;
Let me know if any of the values above seem out of whack based on your experience.
Thanks!
