160 Inch screen will get me 16:9 ratio?

[fred87nc]

Once I get the movie playing, it gives me those two black lines. is it possible to fill the whole screen with 16:9 or is this normal?

EDIT: the screen is actually 179.92126 inch

huh?

when you're talking about a Projection screen, it's height and width (since they vary based on the aspect ratio) but if you have a 160" Diagonal screen size, at 16:9 aspect ratio.... many titles will still have black bars, same as a T.V. etc.

The size of the display doesn't determine whether or not you'll have black bars... it's based on the aspect ratio of the movie with the set display size you have.

I have a hard time understanding how someone could set up a 160" FP display, and not understand aspect ratios

Most films are shot in a wider aspect ratio then 16:9 (2:35:1), which will give you black bars on the top and bottom of a 16:9 screen (I think its around 90% of theatrical films are in a 2:35:1 screen ratio and thus around 90% of films will have those black bars on a 16:9 screen). You can get rid of them on a 16:9 screen but this firstly will cut away around 33% of the image and will also severly reduce the quality of the picture (which will be higely aparant on such a large screen).

To get around this you could run a 2:35:1 set-up which would enable you to never have the projector projecting black bars (apart from 4:3 fottage). What projector are you using?

Apart from the above, this has been adressed numerous times on this forum (and many others) and theres plenty of information about it. Have a read around, and if you are using a projector I strongly recommend a 2:35:1 set-up.

I'm using the Mitsubishi HC1600, I went to the calculator projection thing and got the exact screen for the size of 179.92 and got a screen made that size. My ps3 fills the whole screen, but then when I play a movie it gives me the black bars. I was just confused because on the manual it was talking about no black bars on 16:9.

I'm going to look into the 2:35:1 set up, I have no idea what it is.

anyways here's a pic of my screen

it's still work in process, I got to get those part of the walls covered up, and still waiting on furniture.

A 2:35:1 set-up effectively would require a new screen as it would be the same aspect ratio as the widescreen movies (the lense required can be quite expensive but is starting to become part of the projector [the lense shifts etc are iften done inside the projector], you can also diy a lense very easily and cheaply though it is not of the same quality as the more expensive professionally made lenses). The downside is you when you are playing games or 16:9 content there wil be screen space not taken up by the projected image (though there will be no black bars for 2:35:1 or 16:9 material with a 2:35:1 set-up).

One wasy way to explain what a 2:35:1 set-up is, is when you go to a cinema, often before the movies starts the curtains slide revealing more of the screen. Cinemas effectivly use a 2:35:1 system in that regard (for the most part at least).

Other notes that may help:
Also to note, given that your projector is 720p, 160" may be a tad to big for it (in terms of scrrendoor effect [that is the ability to see sthe pixels that make up the image), as the recommended viewing distance would be 21 feet away, and the closest would be 16 feet away.

Also what screen are you using (do you know the gain). As a 'high gain screen' will be neaded for this projector at the size your projecting it at, that is if you want a bright image).

The screen is actually 180 inches i have the Projector around 7-8 meters away, and the first row starts a good distance, I guess it's the the best picture =( But it looks pretty well. I don't know the screen gain, the screen was custom made by a Company down here in Mexico that dedicated themselves to projection screen.

Anyways, I just wanted to know if it was normal, it seems it is unless I get another screen. Thanks guys.

Best way to check if youre getting significant screendoor is to get a 1080p blu ray movie/documentary that has subtitles. If you can see the picture structure at all you'd be getting a better image on a smaller screen. (even with a 1080p projector, you need a fair bit of distance between the screen and your setting with such a huge screen).

There's no way to get out of this cheaply. If you have a 2.35:1 setup you'll end up with black bars on the SIDE with normal 16x9 stuff (like the PS3 games).

It's just the nature of the thing. Most movies right now are 2.35:1, Action movies are almost 100% 2.35:1 witch are larger than 16x9 in Homes.

Unless you want to zoom in, loose 33% of horizontal resolution, more grain (zoom in just blow grain up) etc.. you can't avoid this

Even at Cinema it's like this. Cinema use 2.35:1 screen with Matte Drapes when 16x9 movie is playing, Drape come to hide the extra left and right side of the screen. When a 2.35:1 movie is playing, drapes just move away with a Automatic electric system.

The big advantage is the projector isn't projecting anything on the outer part of the 16:9 screen. Therefore it is as dark and least distracting as possible.

That would be cool if you colud play games on a 2.35:1 aspect ratio, think about it, playing a strategy game with the scope of Lord of the Rings, a fighting game with the fighters with lots of room, a role playing game (think playing final fantasy). Of course some genres may not work well (Shooters and some action games may work better in 1.78:1 or 1.85:1), but still cinemascope gaming.

Games don't have a 2:35:1 aspect ratio though (at least console gaming doesn't from my knowledge, though it may be possible with a pc), from my experience with consoles you would be cutting out a significant amount of the image (as the 360 only outputs in 4:3 or 16:9, and games are more or less made for 16:9 screens now). But yeah, cinemascope gaming could be very neat.

You can't without a lens, but with one, it's pretty amazing how much 16:9 content looks good stretched. Almost every game looks great this way, especially racing games. Killzone 2 is totally immersive.

To the OP, I would say definitely run all of the calculations for the maximum size 2.35:1 screen you can fit and then determine what size 16:9 that gives you. Next try to estimate how much tv vs movie watching your family is likely to do. More TV might lean you toward 1.78:1. For us it was well worth giving up a few inches of 16:9 height for the width of cinemascope.

Yeah, almost every time someone buys a good home theatre set-up for there first time they learn alot and had they known what they do after a few months of having it, they usually would have gotten somehting else. It's a very expensive interest. but very worthwhile if your a movie buff/fan.

Also with Killzone 2, I don't think I could play in 2:35:1 as I play (90% of the time) online, where sieng everything is a must. Speaking of Killzone 2, I hate it when you're playine with a newb as the sabatour and they shot and kill you thinking your the enemy when disguised. Makes me so angry.

Haha, Suntory, you really do play...I feel your pain more than you know!
