I just had typed almost a page of text about Gregs DVI input for the 1209s and now it is all gone
But I wanted to get this in before christmas so here we still have a few words about Greg's DVI solution:
I think I have tested almost all of the better DVI to VGA converter solutions including the highly applauded and cost effective HD Fury, Spatz boxes, the external Moome and others and I have to say compared to the HDFury which I consider to hold its own against all other solutions in the best possible config (hanging directly at the RGBHV via the short dongle) the DVI input version by Greg still trumps it noticably. I am a lazy person and as I only use 1080p 48 at the most so this is what I tested exclusively. Even better results might be experienced with higher bandwidth feeds. I originally looked especially for better resolution and bandwidth, but two other parameters improved noticably so I will mention them first:
Picture noise: IMO the 1209s is a pretty noisy projector and from my test the DVI mod by Greg has a lower noisefloor and cleaner picture than the HDFury, very visible when someone is closer to the screen and still visible from the seating position I prefer (1.2 screen widths).
Steadyness of the picture: There always was a strange instability of the line structure with the external solutions where one line was a moving and shaking a little in relation to the next and previous line, not much and nothing that rendered the picture unwatchable but it was still there. With Greg's input board everything was rock steady and that was a very welcome change, too.
Resolution and bandwidth: Funny thing is that this is where I did not notice a difference at all and as luma resolution and bandwidth limitations can also be nicely photographed I did that too and the photos also did not show a difference between both feeds that I could detect.
This was tested on a pretty maxed out 1209s with scanlines at 1080p and HD10f lens and only looking at green to just evaluate the raw performance of the DVI card, so the setup was not at fault IMO.
So the good news for HD Fury users is: At least with 1080p 48 the HD Fury looks very nice with regard to resolution and bandwidth.
and for those who want a little extra and are ready to pay for it:
With regard to noise floor and steadiness of the picture the DVI card by Greg improves on all other solutions I have seen and for those who want the best there is it is the right choice. Not the cheapest but the best and that is always a bit more expensive than the rest.
Sorry I di not test higher bandwidths but I just do not believe they are necessary or desirable, maybe my third test would have had a different outcome. Still even for the other improvements I would recommend the product for those who want the best - there is an appreciable difference and it is no snake oil product.
And I might add that Greg seems like a nice person to work with, he sometimes takes a little time for things but in the end everything always worked out fine, I got both the DVI board and P19 LUG tubes from him and will order stuff from him again.
