Guys!

I have a customer near me, two sidestacked 9500s on about a nine foot screen width. Signal A is a BluRay thru an external Moome outputting to a distribution amp and RGB to both 9500s. I aligned the pair perfectly using the Joe Kane 1080p test pattern, copied that to some other memories, and switched to signal B which is a DirecTV satellite receiver outputting 1080i to a Faroudja scaler outputting 1080p to both 9500s.

The image on one of the 9500s was now 1/2 inch wider; we put the BluRay component 1080i thru the Faroudja, same width difference. All signals were identical in scan rate. I am completely baffled why one 1080p alignment did not work on both signals. Any ideas?

Maybe those ferrite width adjustment coils at HDM were different at second marquee?? Does 1080i signals are at low freq. range and 1080p at high range.

Did you try switching the outputs from the Faroudja to see if the opposite projector had the wider width?

Let me clarify. The 1080p grid through one path aligned perfect via HDMI and the Moome. The same settings were misaligned coming component through the Faroudja. All signals are 67khz to the projectors, the satellite should have looked perfect on the BluRay settings.

WOW... Just when you thought you've heard it all. Tim stumped over a Marquee related issue, when is hell freezing over? Laughing

Ok so one input id the moome the other is to the RGBHV right? I have no idea if that is how you have it. I did an experiment on my blend where one PJ had the moome and the other had the RGBHV both blending. i just copied the settings over from input 2(moome) to input 1 (rgbhv) and it lined up perfect. So if it worked on a blend it should do the same for the stack. Might be one of the caps on the HDM when switching resolutions is not right. try swapping HDM'S and see if the issue follows to the other PJ, but you'll have to converge both again.

but you might have top actually play with the timings from the Fajoura if possible, the total , front, and back porches might not be exactly the same as the moome cards.

While both sources might be 1080p, technically, there is always variation from one devices 1080p to another, it ALWAYS happens, no two devices define the resolution exactly the same. Usually, they are close enough to use the same memory/input but often they are far enough apart that to achieve a "no adjustment" condition when switching, there needs to be individual memories per device. I've got half a dozen sources of 1080i and run into the same thing all the time. Just today I had to make a new input for my BEV HD signal because it varied enough from my FTA 1080i that the NEC wouldn't pick the correct input. Both 1080i, different signal...

I'm a bit shocked you haven't seen this dozens and dozens of times before ??

Both the Moome and the Faroudja were fed through Extron ADA-2/300s, same resolutions on all signals, it should have worked on one batch of settings. Chip, this is Hell during the summer and it rarely freezes Smile

Alright, now you threw in a device that you didnt mention before. How about a specific description of all devices and hookups.

Or wait, maybe you said the amp but didnt say the Faroudja ran through the amp

If your using 2 Extron boxes for each source, did you try switching Extrons to see if the problem followed the box?

OK

DirecTV receiver, model unknown, 1080i component out to Faroudja VP5000, RGB out at 1080p to Extron ADA-2/300 to both Marquees. Samsung BluRay, model unknown, HDMI out at 1080p to Moome external, RGB out to a second Extron ADA-2/300 to both Marquees. The Extrons are not capable of mucking up porches or timings.

AM I understanding correctly that 1 projector is switching with no problems at all and the other one changes size when switching inputs. Is that correct?

You need to have the moome external box go into the faroudja then have that out put to the extrons. the moome and faroudja are outputting different timings. if you can reduce the timings on the faroudja till the grids line up the same as the moomes box then it might work, doe the Faroudja even have adjustable timmings?. otherwise you have to get stuck making a new memory for each source.
