|
|
I picked up an HD-DVD payer today (not the A@, but the A3 with *9* free HD-DVDs from Best Buy), and I'm trying to setup a recall memory for it. For the life of me, though, I can't fit the whole image from the setup page on the tube.
I have:
A3(@1080i) ---HDMI---> HDFury ---> RTC2000 ---RGBHV---> Marquee.
I can fit the height of the image on the tube, but not the width. Any pointers for how to get this squeezed in? I can roughly center it by adjusting the phase, but it seems like I'm missing 10-15% of the horizontal.

AFAIK, you can't. The porch timings on these players are all screwed up and you need an external scaler to change it. One of the reasons i'm looking at an LG DVD Romm drive for my HTPC even though I was really looking forward to losing the computer.

Agreed, thats the reason I sold my Blu-ray and HD-DVD players. The porches are all messed up and the all seem to clip the image off.
The LG combo drive is the way to go.

well, crap!
My HTPC is Linux-based, so I'm SOL when it comes to just slapping in a BD or HDDVD reader. That *really* sucks when you consider that my A3 HDDVD player runs Linux.
Would adjusting the H size on my RTC2000 help a little?

Change your retrace timing from the default "Long" to "Short" and you shouldn't have any trouble getting it all on screen..... it can't be that easy ? Can it ?
Works with my HD-A1 and ancient M8000...

DOH!  I can't believe this is the first time anyone has thought of actually fixing the problem at the projector end. Does this really work, are youy getting the whole image. If you shift Pahse left/right there's nothing extra?

Uh, as far as I know, yeah, I'm pretty sure I'm getting the whole image...I guess I'd have to throw in Digital Video Essentials and have a look to know for absolute sure, but yeah, I'm pretty sure I'm getting the whole image...

Maybe an older 8000 is different from later 85/9500s? Short retrace with a modern Marquee is about 1.8uS. Horizontal blanking of 1080P is a little less than 3uS. The video will fit the raster with no problem.

I think there are only 14 M8000's older than mine, its a Sept. 1993 vintage with serial number 024200015.

I've actually had some time to mess with this on my M8500, HD-A2, and Moome HDMI card. 1080i chops off the last couple of inches of the projected image no matter what I do. Changing re-trace from Long to Short only makes it a lot worse. Luckilly, 720P fits the screen just right and also gets rid of those giant scan lines at 1080i, so it's what I will be running the A2 at.
