|
|
Hey guys, there's a new guy with HDFury1 issues. We're trying to solve a rolling line issue. It doens't seem so far to be a gorund loop/dimmer switch on the circuit or electric motor on circuit issue. That got us to thinking it may be an incomming signal issue. Anyone near by Omaha that has an Extron box or better yest a Box1020 with the IAC circuit?
Angryht has a Benq 6200 projector and would like some help testing the HDFury with the Box1020 or Extron before he spends anymore money.
Can anyone help?

I'm not all that close to Omaha (though I do drive through on occasion  ) but I've got an Extron 202xi with the oddball Extron cable that I'd sell for $25 plus shipping, if he decides he needs one... and an RGB 202 that I'd throw in for free if he wants it.

I will probably take you up on that, gary. I just need to figure out what an Extron 202xi actually is. Let me take a look and get back to you. Thanks.

Sounds like someone needs to upgrade to a CRT  BTW, I'm only 7 hours away if you want to come and borrow the EXtron lying around here .

Baby steps Draganm, we all got to start somewhere.

Based on the information I've provided, does it look like the Extron will work for me?

I really don't know. Jeremy describes a problem where you have to shift the image to get rid of a dark image with lines in it. I'm not currently using my Extron because I haven't noticed this problem with my Moome external box.
I've lost track -- were you planning to use the Extron with a CRT projector? Because the Extron has RGBHV out, and you can't feed that into your Benq.

Would it be possible to take a digital picture of the artifact? Your description of it sounds similar (but definitely not identical) to a line I'm seeing with my CRT and HD Fury 1.
My line is much slower, though. I don't know the exact number, but I'd say it takes maybe 30 seconds plus to travel the full height of my 54" high screen. I'm running 1080p. Might be a ground loop - just haven't gotten around to doing any testing because it's pretty subtle and really only noticeable on bright scenes.
I'm in Des Moines. Not sure if you're ever over this way, but if you are I have a minty Extron 109xi with H.SHIFT you could borrow if you wanted. It has a standard VGA input, but has RGBHV BNC output. Of course, the shipping both ways would probably cost more than Gary's Extron box.

I am running an HDFury between a blu-ray player and a digital projector so the fury is converting to a RGBHV MALE D-SUB 15. The Benq is a digital projector.

Actually, I am getting a scrolling line (like a horizontal shift) that travels from bottom to top of screen periodically. It is most prevelant when there are slow camera pans. I have isolated the projector and the source with cheater plugs and using the same AC outlet and it did not go away. I don't have any humming or buzzing. I don't think it is a ground loop issue.

OK. The Extron cable has Dsub15 *in*, but the Extron box has only RGBHV *out*. Don't think it will help you.

But isn't Dsub15 and RGBHV the same thing? Fifteeen pins, right. It's just a VGA input into the projector. Just like a computer monitor.

RGBHV out is the same as the Fury which works but I think it's not syncing correctly with the PJ.

Oh, now I see the output is BNC. So all I need a BNC to VGA cable, right? Is that what the oddball cable is? | garyfritz wrote: | | I'm not all that close to Omaha (though I do drive through on occasion ) but I've got an Extron 202xi with the oddball Extron cable that I'd sell for $25 plus shipping, if he decides he needs one... and an RGB 202 that I'd throw in for free if he wants it. |

Yeah, the RGBHV out of the Extron boxes are on individual BNC connectors, so you'd need VGA-BNC breakout cable.
This isn't sounding like a sync issue to me. The red flag for me was when you mentioned the "tearing" and that it was more noticeable on pans. A synch issue should (in general) be irrespective of program material.
To me, it sounds like a scaling issue with the internal scaler. Do you have another display (a CRT monitor preferable) that you can test the HD Fury and your source with? I'll put my money on the fact that your source and HD Fury will look fine on a different display, and that the problem is the scaling in the BenQ projector. Probably not what you want to hear, of course.

Good point, ecrabb. I will check my CRT monitor and see if I get the same result. Won't the Extron address this?

If it's a scaling issue, no - Because the Extron isn't scaling... It's just adjusting the signal timing slightly. The BenQ still has to scale whatever analog signal you feed it. It has do an A/D conversion, then scale it (and deinterlace it in the case of 1080i) to the panel resolution (to fit 1024x768). I could be wrong and it could be sync-related - but I don't think so.
You'll very likely want to run 720p, as I highly doubt the scaler/processor in the BenQ does a good interlaced to progressive with inverse telecine. It's probably just doing bob.

Yeah, I forgot you could get a 5BNC -> VGA breakout (breakIN? ) adapter. So it could work, assuming the Benq (or whatever) has a Dsub15 / VGA input. But listen to SC, he knows what he's talking about.
