 |
|
Just wondering if I was to use a screen size of 48 X 96 approx 99 inch diaganol 16:9 made out of wilsonart. Which is approx 1.3 gain would this be more suited to an 8" or 9 " crt projector.
Sort of looking at marquee 8500, nec xg series and marquee 9500.
I see in the crt primer that you can get twice of long life out of the tubes if you do not project to big and too bright. Looking to see what the opinion of others is on tube life on that screen size with an 8 vs 9 inch crt.
Also wouldnt mind the opinion of others on the projectors listed.
Also how important is liquid coupling.
I will be using the projector for almost all 16:9 hdtv viewing, bluray and ps3 and xbox 360 gaming. I will not be viewing web forums and so forth.

That size will work for you.

If you can swing it go for the 9500 and don't look back.  Unless you already have a place to get a 9500 I'd drop Curt a PM and talk. You not only get a machine that's been thoroughly checked out and updated but he has top knotch after the sale service. http://www.curtpalme.com/CRTforSale_HighPerformance.shtm

Meh...I wouldn't worry about hours. If you get a 9500 from Curt it will have great tubes with close to 10K hours available IF you make sure to optimize the rasters and use as much of the tube face as possible without wrapping the image off the edges.
I wouldn't worry about "too bright". You WANT as much light out of it as possible. A good greyscale adjustment will produce all the output it's supposed to have.
Also wouldnt mind the opinion of others on the projectors listed.
Also how important is liquid coupling.
If you can compare an LC and an AC machine before buying go ahead and research for yourself. I'd go with an LC if I were shopping. An AC Marquee can be converted later but again, if you have the $$$, go for the 9" LC machine.

Plan on adding an input option to go with whatever projector you get, regardless of brand. You can feed RGB to it but you won't have HDMI or gamma adjustment capabilities.

Also be weary of throw distances. 9" machines need a longer throw distance (distance from lens to screen) than 8". It's not a bunch, but if you have room constraints, you need to take that into account as well. Like Greg said, if you can swing it, 9" LC is the way to go for the very best picture. 8500s are no slouches though, so if you are tight on cash and want to learn CRT, an 8500 is a nice starter as well.

Another question all my sources are 16:9 except my dreamcast which is 4:3. I am seeing in the primer that a 4:3 source will project off the screen top and bottom not like with a digital where it will fit with black bars on the sides.
Wondering if I take the 4:3 640X480 dreamcast signal and input that into my onkyo pr-886p pre pro and upconvert it to 1280X720p or 1920X1080i or p will that make it fit on a 16:9 screen?

When I switched from an 8000 to a 9500LC, I swapped projectors and that was it. I was running a maximized raster
at a screen width of 96 inches and with the 9500LC I'm still running maximized rasters at a screen width of 96 inches.
My lenses are HD-10GT17s, for now.
It works out that the CRT face size change between 8 and 9 inch CRTs pretty closely follows the differences in lens magnification ratios. The end result can be no significant change in picture size after a few simple tweaks.

You'll be creating unique memories for different AR's/sources anyway. Even if your sources are all set for 1080 you may notice image shift or different porch settings etc. One thing to note...not many people are happy with the 1080p image a stock Marquee 8500 puts out. I've never pushed mine that hard but I hear the image is too soft.
Mike Parker is at the forefront of providing a solution to that if you decide to go the 8500 route and want to it to do 1080p. Most would agree the sweet spot for an 8500 is 720p without mods. Even if you did get the 9500 you'll eventually be calling Mike to get his latest VIM for it just to make it alot better than it already is. 
You CAN upconvert the Dreamcast 4:3 but you might not like how it looks. It all depends on what your Onkyo does to it. It's wasn't designed to emulate a standalone processor so I wouldnt' expect too much out of it. However I'm thinking (uh oh) it will stretch it out and the pic will be horizontally compressed? Others can answer that better as I don't own a video processor. I set up different memories for each source and make adjustments to the memories accordingly. (Now we're talking masking but that's another subject)
I shy away from 4:3 content anyway...especially video game content from older consoles. You don't want to put excessive wear in a 4:3 pattern dude. It will stick out like a nun at a porn convention when you run 16:9 sources. It might not sound like much right now but you WILL notice every little thing about the image and it will drive you nuts. 
Don't get hung up on the setup and tweeking right now. Just decide on a pj that fits your home and go for it. We're all here to help you help yourself when you get to the nuts n bolts.

I still have my orginal nintendo and PS1. They will NEVER be hooked up to my projector again. I used to run them on my M8000, but not on this pj with new tubes.
WC, you will find that this group is pretty fanatical about their tubes and tube wear

I bought a acer h5360 3d ready dlp projector a while back. It has bad rainbow effect particularly dark scenes with bright lights. I think I will try and run a dual setup. the acer for gaming and 4:3 kids shows and the marquee when I get it for 16:9 worth watching material.

not sure where you got that info? If you set-up a Marquee for 16:9 native AR (requires anamorphic squeeze mod and included with HD mod's package), it will show 4:3 letter-boxed with black bars onm the sides. Same thing for 2.35 movies, black bars top and bottom. This is how the vast majority of CRt are set-up, not many do native 4.3 or 2.35 but a few do.
