|
|
Sorry if this has been asked before. I did a search but couldn't find anything. I'm currently running rgbhv on port 5 of my bg808s. I've thought about getting a hdfury1 red edition and running my htpc through that. I'm set at 1080i@96. Would I see an improvement in picture quality worth the hassle?
I think I'd see the best pq boost with a new green tube. But no luck in finding one on the cheap. 
thanks!

HDF1 will bring a huge step in pq when you haven't a HTPC or scaler in your setup now.
But the major step will running the color calibration for dummies.
Are your red and green colorcorrected (filtered or tinted)?

I didn't see any improvement with older Moome stuff on my XG, in fact it was worse.
A gen 1 HD-Fury was equal to RGBHV.
I seriously would not bother. HDMI is a pain anyway. VGA just works and your levels don't get messed up.

I am with mark on this one, unless the cabling to your projector is junk or faulty I doubt you will see a difference in picture quality. I had moome's first converter as well as John's converted and ended up selling them both because there was no gain in video quality (or a slight loss) and I used only an HTPC anyway so I don't "need" HDMI/DVI. The only reason in my opinion for these cards is if you have a source that doesn't output RGB.

Don't get me wrong. I've had a step in pq from using an yuv to rgb-converter to HDF1.
In case of using HTPC, Scaler eg. im with mark and secstate.

I have gone through the color calibration for dummies many times and it has made a huge difference. my lenses are not color corrected and I believe my cabling is decent. The corrected lenses and mounts are just too much money so I make the best of what I have. green tube is too expensive too. So... probably best to wait for a better pj to drop in my lap. Thanks!

I wish I knew how to manually fix astig as mine is off in areas and I think that would make the picture sharper. I'm nervous about sticking my hands in there.

Have you tried adjust the electronic astig controls in the service menu option? At least there you can write down the current settings and get them back if you mess it up. No working near high voltage required. If your center zone looks ok I'd start with the electronic controls first.
