|
|
Hello guys,
a friend of mine has his Barco 1209s Graphics fully modded with the latest Eisemann professionally setup.
Processor is a Lumagen XS+.
He found out yesterday, that the 1080P 72/75 Hz signal going to HDMI
input of the modded input card doesn't accept the signal.
are there any Barco 1209s and Eisemann mod customers out there that
had success with the Lumagen combo inputting 1080P 72/75 Hz signals.
Lumagen processor has been checked with Computer CRT monitor and
it works there.
A Laptop with VGA 5 BNC has been connected to the Barco and it works
too.
any help appreciated
Michael

Have you asked Greg? That would seem the obvious first step..

Card hdmi chip is probably limited to 165Mhz pixelclock like all hdmi devices that time.
1080p72 goes over that.

From another site :
The maximum pixel clock rate for HDMI 1.0 was 165 MHz, which was sufficient for supporting 1080p and WUXGA (1920×1200) at 60 Hz.
Sounds like Ile is correct.

Our new chip is 1.3 225 mhz and can do 72 HZ
The issue is many units have handshake firmware issues that prevent. If you ship your scalier / player to us we have a special service that we custom make firmware then re burn it onto the chip.
Our board is totally custom and requires a lot of work. Many hours of labor for my mod guy and we change every circuit in the signal path. Its really a nice mod now. The work required is huge and almost not worth the cost.
Our internal barco card is the sharpest most stable solution for barco projectors. We are on V15 now.

but exactly this new V15 does not do 72 Hz . is there a way of using an external solution, like the
HD Fury or Moome's new HDMI 1.4 box to be used with Port 3?
what do you plan for HDMI 1.4 comaprtablilty (3D ) ?
btw, the installer was totally in awe of the noise floor seen on this mod and projector.
Hat off to you Greg, but, the sharpness is not 800% better  or what figure was it you used a while back ??
but the best he has seen on any Barco projector so far

Yes it does do 72HZ .. I have to investigate why this one does not. There have been a bunch sold recently without an issue its possible some of the early boards had problems back in Jan but that was more of a total black level cut out issue.
We have had a few customers have HDMI issues and it turned out to be the source equipment manufacture firmware in many cases (Sony was terrible on their early gen blue) was an issue and they didn't want to update.
One was actually a bad chip that had handshake problems and another was actually a bad bypass cap on the barco so it would scramble the pic at over 60HZ that was a weird one and I finally tracked down when I removed the cap and replaced it.
I told the customer to send it back for testing to see if we could reproduce the problem, sometimes my firmware machine does not encode perfectly so there could be a bit issue.
The figure was 75% sharper typically but it depends on how good your optical focus is, simulation vs non-simulation grade tubes, magnetic adjustment, and finally electronic focus adjustment of the projector.
The noise floor is much lower because we add caps to every op-amp we replace.
I replace all the opamps with lower noise/ higher bw replacements. I also add two caps to every opamp in the video chain and solder the cap right to the new generation op-amps so the noise is killed right at the amp.
I hope that helps some
Greg

Can he test Lumagen 1080p72 with some digital device, it could be different thing than analog output.
If I remember correct also Lumagen is near it limits with digital 1080p72/75 and works only with minimal porches.

Lumagen Hdp pro or HDQ can only output 1080p72hz on the analog side. And even worse if you try to use HDMI OR DVI as inputs the HDCP police shut down the output.
A HDCP device has been detected output has been disabled.... displays on the screen. 
The Radiance units I think only the plus models can do over 60hz, but I've never used one to be sure that is the case.
Edit: OP posted radiance XS+, so it should work.

Nope, the XS+ can do up to 200 MhZ pixelclock.
mine works fine with 1080P 72/75 Hz with Moome Card and Marquee
