Hi all,

I have a Lumagen HDQ capable of outputting 1080p at 72Hz, and a Barco 1209 which is very happy to display that resolution image as long as it is fed via RGB. So far so good. Where it all goes horribly wrong is with HDMI sources running at 24fps.

48Hz is do-able via a HD Fury but it is flickery. As you all know, 60Hz is juddery. 72Hz would be ideal but the Fury doesn't go that high. So, the big question is what is everyone else using as a HDMI to VGA interface to solve the 1080p/60Hz max of the Fury?

Edit: At the moment an Eisemann DVI input board is over budget, so I'm looking for an interim solution.

Regards

Chris

You can run the HDFury1 at 1080p/72 as long as you don't exceed the 165Mhz DVI single link specification. Can you adjust porch timings on the Lumagen? You may be able to get to 1080p/72 that way.

Also if you are watching alot of 2.35:1 movies you can set up 1920x807/72Hz and be well within the 165Mhz DVI-SL limitation.

Yeah, I can dial in porch settings on the Lumagen. Have you got any recommendations for the timing settings?

Let me update the thread title, one of the lumagen guys can jump in here.

First off how are you running this in your chain?. The Only VP i know that can do 1080p@72 out of its digital outputs is the Tv-one C2-2xxx series of Processors.
the Lumagen can do 1080p@60 from the digital and from the analog outs it should can do 1080p@72 no problems.

So I asuume from what you wrote in your first post that you have the HDfury at the PJ and running the DVI out to the Fury from the Lumagen. this wont go that high up to 60Hz for 1080pfrom the HDQ's DVI.

I would put the HDFury before the HDQ and input 1080p@24 to the HDQ and then output the rgbhv at 1080p@72 to the Barco. That should work fine.

I am not sure what the Barco likes for sync timing but try large hsync and Hfrn. But try the default first then mess around with them.

Ah, this could be the problem then. DVI out doesn't go above 60Hz. Got to scrap the idea of Fury at the pj end and go with it before the scaler.

Have connected RGBHV from Lumagen to Port 5 (RGBHV) on 1209. OK, our sources are (don't laugh, please) PS3 and XBox 360 with HD drive.

Tried PS3 in to HD Fury1, then out from Fury on RGBHV in to Lumagen on input 5 on RGBS using T piece to combine H&V syncs. Went through PS3 video set up. 480/576p and 720p OK. 1080i very jittery. 1080p a no go. Made sure Lumagen set to accept RGBS. What am I doing wrong?

Haven't tried XBox 360 yet.

Just curious why are you combining syncs?

Is RGBS what the HDfury outputs? I am not familiar with is, just the HDQ. When in the HDQ set it to accept 1080p@24 then you should be able to select
what type of signal it is 4:2:2 etc. and RGBS. I am not in front of my HDQ so i cant remeber what the input options are. make sure you use the correct one.
Try the HDQ with no source into it or on to the barco, use the internal menu test patterns and see if you can get it to show up on the screen, then turn on the source and tweek it that way.
Aslo i dont have a barco so it might be some set up in that menu also.

Hi AnalogRocks,
HD Fury1 outputs RGBHV on 15pin VGA and comes supplied with breakout cable VGA to 5 x BNC. (Fury2 can output either RGBHV or Component, but we've only got a Fury 1)

Lumagen inputs 5 & 6 accept RGBS if selected from the input menu. Lumagen inputs 3 & 4 are DVI-I, and would accept RGBHV if we had a VGA to DVI converter plug, but we don't. Sad

Our only way to connect HD Fury to the Lumagen is RGBS (combined syncs) in to input 5 or 6, so that's how it's wired at the moment.

Yassou (sp?) Athanasios,

DVI-I inputs have options to change input type 4:4:4 / 4:2:2 etc but not seeing the same on input 5 & 6 set up. Only choices are RGsB, RGBS, SCART. I'm assuming that 5 & 6 will accept baseband 15kHz through to 72kHz'ish signals via RGBS. Am I barking up the wrong tree?

Thats what the problem is, inputs 1-4 can be RGBHV, you need an adaptor to go from the fury to the DVI so a VGA to DVI-A adaptor.

So 5 & 6 won't accept HD resolutions?

They will but you must have the wrong sync set up. not sure what the HDfury does with the syncs, it might only be RGBHV and combining syncs like that wont work. Not 100% sure though. And getting sync on green is a tough one also to try.

Just use a computer video card VGA to DVI adaptor. In reverse.
