16:9 vs 4:3
« on: December 14, 2008, 09:24:37 pm »

We have just bought a 9'x16' outdoor screen and are looking into a projector to match. i posted a previous topic about this but now i have a different question. We will be using the projector in our youth room with a 150" 4:3 screen when we arent using it for this outdoor movie screen. I am thinking about going with the 16:9 projector and just raising the screen up a little in the youthroom to make it a "wide screen". The other option is to get a 4:3 projector and turn it on 16:9 mode which will make me have to jack the zoom up to get that 16x9 image to cover the whole movie screen which could ruin the brightness and detail. what do yaw think?

The projectors i am looking at:

16x9:

4x3:

thanks,
Kristian

ps: And if anyone nows of a good, brighter, higher contrast WXGA projector under $5000 let me know. if that would be the route I should take

Also I will be needing some good quality coax and HD15 to coax adapters for the projecotr when it is in our youth room. About 100' of it. Anyone have suggestions on brands and places to buy??

Right now Ive got 100' of junk I got off ebay for 20 bucks sending signal to the current projector out of the FSR CDA-4 and the picture quality looks aweful, so I want to do it right with this new projector.

thanks again,
Kristian

I would go with a Panasonic PT-DW5100U. These are great, quite and have RGBHV terminals right on them. Do be aware that this projector will only be useable at dusk/night time as it is nowhere near enough power to use during the day, but at 5500 lumens it would be the best you can do for (right at) 5K (if you look).

In keeping with the above recommendation I would recommend buying a 16x9 projector and putting it into 4:3 mode when needed. That, to me, is a better compromise than using a 4:3 in 16:9.....

From an authorized dealer?  Many manufacturers' warranties and support may not apply if you don't purchase the equipment from an authorized dealer.

As far as adapters and cable, would it be HD15 at the source and RGBHV on 5 BNCs at the projector?  Would the cable be run on the floor or in conduit or might it run through a plenum space?

heres the projector on ebay...

As for cable, yes i need one HD15 adapter for the coax and it would run along the floor then up a wall and across the ceiling to the projector. all right against steel trusses if that makes any difference.

The comment from that vendor that "All of our products are covered by a warranty of 1 years parts and 90 days for labor. Due to our very low low prices, we are prevented from listing our items with manufacturer warranty. Our products are the same as if you bought in stores." is a bit disconcerting, especially since Panasonic's warranty ( ftp://ftp.panasonic.com/pub/Panasonic/Drivers/PBTS/manuals/W T_DLP1.pdf) is 2 years parts and labor on the projector, 1 year parts and labor on the fan and 90 days (or 500 hours) on the lamp.  In fact, it appears the projector spec data shown in the referenced e-Bay listing was taken from Projector Central but the 2 year warranty shown there has been deleted in the e-Bay posting.

I also noted the comment in the e-Bay listing that "All products listed as NEW, are indeed NEW IN BOX items. We do not list items as NEW and ship REFURBISHED items." yet nothing for this particular item actually seems to identify it as new.

I would follow Karl's advice and look for someone who seems a more legitimate dealer.

The "across the ceiling" is what could be a factor if that above ceiling space is considered a plenum space, in which case you would probably have to use plenum rated cable.

All this RGBHV jargon is running together in my head...
Is this what I need with an HD15 Adapter for one end??

And I think We are gonna go with the panasonic. And It comes to find out there are a little more funds available so I should be able to afford to buy from a reputable dealer...

 http://www.ramelectronics.net/audio-video/video-cables/hdtv-  projector-cables/rgbhv-cables/rgbhv-cable-5-bnc-to-5-bnc-556 11/prod55611.html

In general, yes.  RGBHV is using five separate wires to carry the video signal information, which allows for larger, lower loss cabling to be used than you find in typical VGA cabling.  These five separate cables are then bundled in one overall jacket for RGBHV or 5 wire cable.

However, I am never comfortable with cables that don't tell you anything about the product, such as the conductor size/gage, losses, rated use, etc.  Compare the cable you noted to the type of information provided here, http://www.extron.com/product/product.aspx?id=5condmhrbncmbn cmc&subtype=54 and in the specifications for the actual cable used in those found here http://www.extron.com/product/product.aspx?id=bnc5mhrcable&a mp;subtype=260.  I'm not saying that is the right cable for your application, but it is an example of a well defined product.  As to why this makes a difference, look at http://www.extron.com/product/listbytype.aspx?subtype=54, you see three different general types of 5 wire cable that differ significantly in the cable used and the related performance and cost, including one version that is plenum rated (MHR-5P), which is required by code if the cable is run exposed in a plenum area.
