Projector Room, Projector and Screen Questions

[msk2013]

msk2013-- I am not sure I understand what you mean by bigger screen (lenghtwise)--
the screen has a height and width

yes height also will increase ie instead of using 8x6 ft screen probably we can use a 11 x 8 ft screen.

Hope I am not confusing the matter

Are you planning for iMax kinda screen? Curved screen is used to remove the pin cushion effect while using an anamorphic lens or the edge focus issues in a projector.

Guys, isn't there a perfect 2.35:1 screen for 8100 ?

The Epson native resolution is a 16:9 projector. A 120 inch diagonal image will be 58.83 inches high by 104.59 wide

keeping the same width of 104.59 inches wide-- for a format of 2.35:1, the height shall be
44.5 inches with bars of 7.2 inches on top and bottom (You will not see the bars when you are watching the movie). This is effectively becomes a 114 inch diagonal 2.35:1 screen

Now going the other way-- if you have a 114 inch diagonal 2.35:1 screen and image---and want to display a 16:9 image-- the height of 44.5 will dictate the width-- 79.11 inches.

In reality this will not happen-- The width will stay the same (104.59 inches) and you will have a height of
58.83 inches--- the reason for this is projectors are designed so that the image stays on the screen

So to answer your question-- you should get a
1) 16:9 120 inch diagonal fixed screen from liberty Grandview
or as an option
2) 16:9 120 inch diagonal curved fixed screen from liberty Grandview

16:9 : 150 inch screen also should be okay, right ?

Who is the best guy in Delhi to contact for Grandview demo ?

 

[Thtpro]

150 inches 16:9 screen will have a will have a viewing area of
a) 130 inch wide + 4 inch border or a total of 138 inches width
b) 73.62 inch tall + 4 inch border or a total height of 81.62 inches

So if you ceiling height of roughly 120 inches (81.62 {screen + border} +24 {spacing at bottom} +12 {spacing at top} = 117.62 inches)

You should be fine

So, what is the recommended size for the room, if I want to have a 150 inch screen for a 8100.

Length : 17 feet
Width : 14 feet
Height : 11 feet

Is that okay ?

Stop worrying so much. It'll be fine.

And as far as 2D blu ray movies are concerned, you WILL have to deal with black bars on top/bottom. If those end up bothering you too much, DIY masking will fix it pretty easily and cheaply.

For grandview screens, Abhi projections is the main supplier in delhi. I contacted a few others and they all were sourcing the screens from Abhi only.

Soamz,

It is not only false ceiling which thunders, there will be other things in the room which could face a similar situation like the loose placed things like a glass, bottle, room decor items, etc. These thunders are in a way good because it does add to a extent the power of low frequencies backed with acoustics.

Please be assured you will not regret a false ceiling, you can consider the various ways by which others have done and then there are acoustic type of tiles too.

It is a very good idea that you are considering a good lighting set up, especially if you go for dimmer and fading options.

Im looking to have a false ceiling for a good lighting setup , but then again I think, when we watch movies with good bass, those false ceiling thunders a bit and adds to the bad experience.

 

[soamz]

Guys, how about getting a 2.35:1 screen,
Amazon.com: Elite Screens R166WH1-WIDE ezFrame Fixed Projection Screen (166" 2.35:1 AR)(CineWhite): Electronics ?

Epson 8100 natively dont support that zoom or does it ?

Vinay,
I dont see much threads in this forum, how people have done it. Im taking ideas from AVS Forum , but mostly things are not available in India .
So, I have decided not to have the false ceiling , just have thick black wallpapers on the walls and a thick carpet on the floor.

For doing 2.35:1, you either need an anamorphic lens or zoom method. For zoom method to work, you need powered lens zoom + focus. if the projector has lens memory, then all better. Epson 8100 has none. It only has manual zoom + focus. For that you need to look at Panasonic AE7000.

 

[soamz]

I just calculated the quote for that projector on iShop :


Item price + local shipping + taxes RS. 115,445.00
Int'l Shipping RS. 9,680.00
Duty, Taxes & fees RS. 36,254.52

TOTAL RS. 161,380.00


I guess, its a good over, rather than getting the Epson 8100 for 1.4 lacs from India and then worry about the 2.35:1 content later ?

 

[nSinghal]

Epson can do anything which another PJ with lens memory can do. Just that instead of touching a button n the remote you zoom in/out, re-focus, and adjust lens shift everytime you go from 2.35:1 to 16:9 or vice versa. It'll take appx 5 min every time but itll be a real PITA. Using DIY masking will give you the same results as a 2.35:1 screen and much much easier to implement compared to using a 2.35:1 screen with a no-lens-memory PJ.

Also, that 166" 2.35:1 screen is going to be too big for your room. Stick with 150" 16:9 or smaller IMO.

 

[soamz]

Yes, 150 inch screen. I was just giving an example.

I was reading AVS Forum that, there are special 2.35:1 screens .

About the projector, Im confused man. 16:9 gives a squeezed experience and 2.35:1 uses that black space, giving a better experience.

Can we manually set the epson lens to always cover the whole screen image display ?

 

[soamz]

For the Epson tw8100, with a 150 inch 16:9 screen -- you need a throw distance of minimum of 178 inches-- so I would suggest the following-- either reduce your screen size or expand your room to a depth of 16.5 feet

Screen you can get them from Grandview-- You can get them in fixed frame or curved fixed frame

Just talked to dad and the construction guy. He said, we can have the room size as 20 x 20 . So that's like a huge room now

So we can have the 150 inch fixed screen from grandview and hang the Epson at middle of the room length like at 16.5 from the screen ?

[soamz]

Our room size has been finalized . It's 20x20

Can we have a 200 inch screen which is 15 feet long ?

I got one, http://www.amazon.com/FAVI-HD-200-16-200-Inch-Projector/dp/B0041D3B2G/

What do you think ?

Can the Epson 8100 completely support a 200 inch screen and brighten till every corner of the screen ?

Let me know.

A 200" screen is probably not even going to be possible with the epson in your room. Epson requires 17.7 feet from lens to screen for 180" acc to its manual. For 200" I'd assume it requires atleast 19 feet. Then you have to factor in the PJ length itself. Not possible. And even if it was possible, it'd still not be advisable.

See, the PJ gives you about 800 lumens in calibrated modes. That's when the lamp is brand new. For a 150 inch screen, that translates into 12 foot lambart. The absolute minimum most would recommend for a PJ screen. At 200" you'd get less than 7 fL. It'll barely light up the screen with a new bulb. Forget about 3d which effectively reduces screen brighteness by almost 50-60%. It'll be unwatchable IMO.

You definitely should get the projector first and see for yourself how big a screen is actually possible before it becomes unwatchable. Otherwise it's quite possible you'd be wondering next week... "what if I fit a 18 feet wide screen. Is that possible"

 

[soamz]

I see.. Actually, the room size is going to be 20 x 20 , which is really huge .

I said the contractor to make it 14x20 , so we can have a tunnel type room and would be very nice.

But he denied, as the pillar has to be on the foundation pillar only

So, 20 x 20 . So, if we put on a 150 screen, that like using 11feet of the wall and other 9 feet looking like a empty space.

So, 4.5feet space on each side.

Isnt that a lot of free space ?
