Double fresnels vs. two single ones

You cut your fresnel.. you are braver than me!! 🙂 You mention component inputs... is this the Audio Authority 9A62 component thingamajig you've been talking about? I've noticed these little halo's around objects in movies sometimes... kind of like someone turn on an edge detection tool in Photoshop... and I would be thrilled to get rid of them.

P.S. - Have you figured out the lens we would need to get our setups farther away?

Yes- I use the Audio Authority 9A62. BIG step up from S-Video!
Here is an older screenshot using S-Video B4 I got the 9A62. :dead:

wow... the images look much more film-like using the component video!! :bigeyes:

alas, the $189 price tag on it isn't too attractive, considering I paid $115 for my Panasonic RP-62 progressive scan dvd player, which is an excellent player that uses the DCDi deinterlacing chip, although only through the component out.

i assume the 9a62 doesn't scale the progressive output... so it puts the nec 1545v into 640x480 mode, which isn't native... but from the looks of it that isn't a problem!!
 
480p 640x480

You are right- the 9a62 is not a scaler so these images are @ 640x480. But the improvement in the color signals from using the component video (progressive scan DVD) make up for alot of resolution! Looks ALOT nicer than s-video @1024x768. What I really want is the viewsonic N-6. Component video input scaled as high as 1280 x 1024. (At least that's how I THINK it works)
Have to look into that.
 
yes it would eebasist, as long as you have good dvd software that deinterlaces the image, and a powerful enough computer to do that.

i wonder how the results of a component to vga breakout cable would be compared to that Audio Authority box... since a breakout cable can be found for $50.
 
BTW I dont mean to go off topic here but maybe one of you knows of a cheaper solution for the following since Proto5 said he uses one also...

To get what I'm looking for I'd need to pair up the:

Audio Authority 9A62 Video Converter ...with
Audio Authority 1154 Digital A/V Switcher

The only problem is price... 400 bucks! If I cant find anything else of the same quality I'm buying it anyway... but I'd really like a cheaper solution.

You could just get an A/V reciever to handle it all.....or if your current reciever doesn't do component video-use it to switch the audio and use a $15 A/V switchbox to switch the video signals. (Plug the component video into the video-left audio-right audio) I did this for awhile b4 I got an A/V reciever.

And just so people dont get confused... a "Field" fresnel is just what you would call a fresnel placed in front of the LCD for the config we're using. So dont ask where to get good field fresnels... theres no difference.

FYI,

Condenser lens = Collimator lens = lens before the LCD panel
Field lens = Collector lens = lens after the LCD panel

There are also different kind of condensers which take a beam in and output a beam also (a narrower or 'condenced' beam so to say). But always collimator takes a point source and converts it to beam and the collector does the opposite.

From the PDF from fresnel-optics there's also a pre-condenser len mentioned. This could also be a useful lens, pratically it shortens the focal length of the condenser (*I think* so to say).
