Will this work

BD Player HDMI to Mux HD then DVI Output from Mux HD to Lumagen HDP via DVI input and then HDP DVI output from lumagen using DVI to VGA adaptor then to Projector. If this does work are there any restrictions in what can be transfered this way.

I want to get HDMI from the BD player to my Projector without a Moome box or Fury.

I should add would the above accept 1080p from the BD player which I may want to scale down to 1080i or leave at 1080p and if this does work with the Lumagen HDP will 1080p via DVI work with the HDP Pro. The specs from Lumagen seem to suggest that the HDP accepts 1080p input via DVI but the Pro does not which seems a little strange.

I would use this for your set up. BD player to Lumagen , set lumagen to accept only 1080p@24 so it forces the BD player to only that res, sometimes a bonus is it will allow the BD player to output 480i for SD dvd's. Ok so then set the Lumagen to output 800p@72 for 2.40 aspect ratio movies, and 1080p@60 or 48hz for 1.78 aspect movies. each output and input can have 4 separate settings Exm, imput 1A= 1080p@24 >outputting 800p@72hz, input 1B=1080p@24>outputting 1080p@48hz. its a great unit, very flexible.

I think they both accept them, you might be talking about the Vision Pro(older pre HDP series). Id get the least expensive one since you could basically use the MUX for up to 4 inputs and the Lumagen can have 4 memories on one input, so you get a nice advantage there. and gain more inputs on the lumagen for non HDCP devises .

yeah that one does not accept 1080p@24, the one for sale hear is the better of the two(MrHiEnd)

Yes it has DVI input but and this is where I could be wrong Lumagen site shows the specs for this as accepting a maximum input of 720p over DVI. Therefore not able to accept 1080p/24.

You'll still need the Moome MUX for HDCP unless you have a Moome internal card in the PJ. otherwise you wont be able to output 1080p form your player, it will shut it off. but you can then go 1080i out and upscale via the lumagen to 1080p. i had it that way for a few months before i got a moome internal card, the lumagen did a nice job upscaling from 1080i to 1080p.

As mentioned first up I need a Mux HD. It seems to me that this is the cleanest sollution. I currently have a Lumagen Vision, the most basic model no DVI inputs so i have been using the component inputs and scaling this to 1080i the Lumagen Vision will not accept 1080i input over component and I have no way of converting component or HDMI to RGBVH to use the passthrough on the Lumagen.

I suppose I could just get a Mux HD and connect a DVI to VGA adaptor to the DVI out of the MUx HD and run this to the Pass through of the Lumagen Vision??

The VisionHDP, VisionHDP, and VisionProHDP all have exactly the same firmware, image quality, and function. All three support 1080p 60Hz output on DVI, and up to 1080p 72Hz through RGBHV analog. All three accept 1080i, 720p, and 1080p 24Hz on their DVI/HDMI inputs. None of the three accept 1080p 60Hz on their DVI/HDMI inputs.

Theoretically, if you are using RGBHV you should prefer the HDQ or PRO because the analog output sections on these processors is slightly better than the HDP.

Also, when using a VP, you should always maintain a digital feed throughout the signal chain and only have one DA conversion at the end. Don't create a system that has multiple DA and AD conversions as you are only causing deterioration of the signal.

Your best bet is to run through the MUXHD and then directly to the Lumagen through DVI. Output from the Lumagen with RGBHV or DVI to a DVI/HDMI > RGBHV converter or IFB.

The Vision processor can also support YCbCr 444 and 422 on their "DVI" inputs. I am not sure that the MUXHD supports YCbCr, but if it does, your very best image from a Vision processor would be to input YCbCr to the DVI and output RGBHV through analog. This way the Vision will support 10-bit color because the DA conversion is taking place inside the processor with CYbCr as the source. The Vision line does not support YCbCr on the DVI output; so if you were to use the DVI out from a Vision you are stuck with 8-bit color.

So run source > MUX > Lumagen > RGBHV
