|
|
Hi,
I'm plan'n on buying a Sony D50, but the problem is i need a 138 inch diagonal 16:9 screen. Will the projector be able to manage it without the tubes wear'n out prematurely? Can i use a curved screen to improve the situation? What type of screen material should i use? The projector will be used in a fully dark room with black and dark grey walls. And i plan to connect it to my HTPC wich can put out 720p component signals and ofcourse the RGB H/V signals, which should i use? And also i'll be buying the projector from for an equivalent of 1500 USD, what condition shoud I expect the projector be in at that price, sound i pay special attention to any particular aspect of the projector and what is the difference between the D50Q and the D50HTU? My orginal plan was to get a Barco 701 but they'r jus not available in india also since its bandwidth is only 45Mhz i'm not very sure if they'll handle 720p signals too well.
Thanks for all you help. I'm new to CRT projector i've only used digital projectors all my life and i don't wanna take a wrong decision.

no, on that size screen you will burn through those little D50 tubes in 5K hours or less IMO.

yes, a Torus will help a lot. You want a max gain of 1.3 for flat but I believe you can go up to 2.5 on a torus? Hopefully someone familiar wit hcurved screens jumps in

That's REALLY high for a D50. I think here in the US You can expect to half that much and it better be in minth condition for $750., come with the remote and the celing mount bracket.

I suggest you aim higher, like a G70

CRT is a lot of fun, I don't think you can make a really bad decision, but some decisions are better than others

I run my D50 on about a 100", 16:9 screen built from Wilsonart laminate, which has a gain of around 1.2. It puts out a pretty good picture. I feed it 600p from a HTPC for DVD playback and 720p from a Xbox 360 and a HD-A2 HD DVD player. Keep in mind that the D50, with its 7" tubes and 5.5" rasters, cannot fully resolve 720p. I think most people put the D50's sweet spot at around 500p. You can feed it 720p and 1080i, but expect a softer picture due to scanline overlap. A G70 or even a 125x/127x with good tubes would be a step up in resolution capability. A 125x/127x would probably cost less than a D50 too. That said, the D50 is still a nice projector. It's smaller, not too noisy, and has component video input. It's also brighter than a 125x/127x. If I could, I'd probably trade my D50 for a 1272Q with similar tube condition, but I'm not complaining too much, especially since I have a 1292Q for the real HD viewing.

why do you "need" 138" diagonal? IMHO, the D50 should stay at about 84"-87" wide (100" diag).

If you're not able to get better than 500P out of your D50, there might be something wrong. 540P/1080i is easy (and sweet) on that projector.
I've got a couple of local friends with D50's and a couple with 1272's. I'm pretty sure the guys with 1272s (with nice tubes) will be interested in contacting you about a trade.

Go smaller and sit closer.

Well after reading all your post i guess i'll just have to stay away from CRT projectors till i can find something that'll suit my needs, like a Sony G70 which i'm sure i'll never get in india anyway. And i can sit any closer to the screen cuz that'll affect the imaging of my speakers when i'm listen'n to 2 channel music.

That's a whole ohter website. 
The sony D50 will be too dim at the 138" screen size you are trying to achieve. Go for a nice 100" diagonal screen or smaller. The picture will look much better.
The difference between the 50Q and the 50HTU is the 50Q has a IFB input slot for card expansion and the HTU ( usualy ) does not.

I have a 110" diagonal Wilsonart screen with my D50. It looks great but I have to run contrast at 78 and brightness at 75. I'm alright with shortening the lifespan of the pj to have a larger screen.

maybe it'sworth asking around for an agent to handle your import of a PJ. Prices here on CRT are much lower than anywhere else inthe world.

Well now you have opened a whoel new can of worms.  I have the same problem in my room. My front row of seats is directyl under the PJ at 9 feet back from a 110" diagonal screen. Second row is 13 feet back and the "sweet-spot for audio is right bewteen them. 
Truth be told, 2 channel audio and home theatre really don't play nice together. you will be making a compromise on one or the other to get both. For me it's worth it, I would not give either one up just to make the other one 10% better.

That is truly the bottom line. Everything from placement to room design to ... has to be different for these two. You can't have both. If theater is the primary focus, then you already have to decide to sacrifice 2 channel quality. The only way to do this correct is to have 2 rooms.

i run my ecp at 70 contrast, around 3, 4 brightness depending on what movie it is. that about average? because it looks good with a 6 foot wide screen. hope its not pushing it too much..

6' wide with an ECP shouldn't be pushing it hard unless you really have a bright picture.

Clarence, the D50 is pretty much just a modern version of the 1031Q with its brighter tubes, digital convergence, and component input. It has 7" tubes with 5.5" rasters and ES focus. It cannot resolve much past 500p, though it will happily accept higher resolutions. I run 720p on it and HD DVDs don't look that much better than DVDs on it. With a 1272Q, that would be a different story with its 8" tubes. I think the 12xx series offers better bang for one's buck. The D50's advantages over the 12xx series are a little more brightness, smaller footprint, component input, and a little less fan noise.

OK, it is kind of funny that you are explaining to Clarence what a D50 is. That not withstanding, Clarence is correct. That PJ should do 1080i much better than it does 720p. You should not even attempt 720p with it. If you can't get a decent looking 1080i, you don't have it set up well.
