I am considering getting a screen and it would be my first. Now I am curious about the aspect ratio. Should I go for the 1.78 or the 2.38 screen? I think some TV would be watched on it but right now I am thinking it will be mostly blu-ray movies. I don't know if I should get one and either format would work on it or just stick with the 1.78 since it seems to be more common? It will be in a small room not dedicated to theater.

This screen will be small compared to some of the sizes I have seen some of you talking about at either 72 or 80". I was also thinking of the Brilliant White since it also seems to be the popular choice. The projector I was looking at was the Panasonic AE4000U. Oh and when I say small room its 12.5x13'

Any opinions?

I went through the same thoughts.

You have probably navigated to the thread above posted by JT. I referenced that as well and thought the same as a few members there. Basically, purchase the widest screen that you can manage within your room/desires etc. Do this and get the 16/9 (1.78).

If you go with an 80 inch screen, no matter what ratio, that would still be the widest you would have. With the 1.78 you can either project on all of the screen with 16/9 material or utilize the same width for a 2.35 movie. On the other hand if you go with a straight 2.35 screen, when you do watch 16/9 TV/movie etc your 80 inch screen turns into less than a 60 inch TV.

Also, don't completely rule out a larger screen due to your small room. I'm a complete newby when it comes to screens and PJ's - I just took possession of my first.

The best advice I read was to get the projector and purchase the screen last after setting up your PJ. I did just that. My room is not that much larger than yours: (16 ft wide and just over 14ft deep). Once I mounted and fired up my new PJ, I watched several movies just projected on my painted wall. After "viewing" in different sizes, even though not optimum viewing distance according to the "calculators", I ended up ordering the Carada 126 inch 1.78 (BW). The wife agreed. :-) Just make sure you take into account where your front speakers will be placed - which may already be why you are thinking 80. My fronts ended up a tad wider than optimum but still sound superb and the visual is perfect.

As for Brilliant White/BW, comparing the Classic Cinema White to the BW revealed little difference given my eye and swatch size etc. That and the other recommendations pointed me to stick with the BW.

Best of luck -have fun!

Love DIY

What is masking?

KJSmitty, what you said makes sense to me. I think I still may just give Carada a call and see what kind of knowledge they can give me on what I have to work with.

I think an 80 screen will be the biggest I can go with with the small space available. Maybe the 84" with frame actually according to the carada site.

I am curious though, if I do what KJ said and get the 84" 1.78 and use the projectors aspect ratio adjustment where I can swap from the 1.78 to 2.35 would that work? I guess it just makes the actual video smaller when going to 2.35.

Well I will try to call Carada tomorrow if I can and see what they say.

For an example of DIY masking, see the "My latest masking trial" thread that I bumped up in the "DIY screens" subsection of the screens forum.

Glad to hear you say this. I posted the thread above regarding screen size and just pulled the trigger on the same screen you have. Sounds like you're happy with your purchase. Any brightness issues? What's your PJ?

Thanks,

My 92" Carada Brilliant White screen arrived the other day. I was previously watching my Panny AE4000 on a primered wall. As expected, the picture is gorgeous. The screen is very high quality. The product is packaged/protected very well. They even have warnings not to use sharps (knives/scissors) when opening. There is a layer of foam over everything.

Assembly was a piece of cake. Everything mated up and went together perfectly with minimal effort. No gaps between frame pieces, the screen stretched perfectly, the snaps were super easy.

Mounting it on the wall was just as easy. The brackets are simple, and the instructions are effective. I measured about 5 times and drilled once. The screen hangs nice and flush with the wall, and looks fantastic with the black velvet frame.

The BW screen definitely evened the picture out quite a bit vs. just throwing on the wall. The texture is a lot more refined, and I can watch with the lights on or off. The picture with this PJ and screen combo is fantastic.

I'm extremely pleased with this screen. I considered going with a cheaper model from a different manufacturer, but I'm glad I didn't. I believe this screen will hold up very well as it ages, and give me lots of enjoyment in the years to come.

I too love my Carada screen (92-inch 2.35:1 BW), which I've been enjoying since April. It was the final piece in making my home theater come to life, and I love watching people's reactions when they see my perfectly-calibrated Panny PT-AE1000 projector flash across the wide screen. Good fun. I had to add some black velvet strips on the wall above and below to absorb the 16x9 overspill during 2.35:1 movies, and I've also got my trusty matte-black foamcore panels that I velcro onto the Carada for 1.85:1 and 1.33:1. It doesn't get any better; a truly great value and a truly great company.

Okay, I know I didn't add much to the discussion; but I wanted to be post #1000.

LOL congratz, but I would love to see some pics of what you have done to your screen as far as the velvet strips and velcro panels go. It just might give me some ideas.

I was thinking of getting the 1.78 (16.9) screen and try to squeeze in the 2.35 on it but if its not to much trouble or works out better I may be interested in doing what you did.

Um, am I missing something here? My screen just came today and when it came time to attach the j brackets to the frame... no pre-drilled holes like the instructions state. I have a rarely used craftsman cordless power drill sitting around, should I mess around with drilling holes in this thing? I'm worried i'll wind up punching through the velvet :/

Hold it their cowboy, that doesn't sound like a good idea. Give it another look to make sure and if the holes really aren't their give Carada a call and tell them your problem. They will fix everything up for you if they sent you a defective unit. If you start drilling holes Carada won't take it back and their is a good chance you could blow $800.

Well, turns out it was very easy to drill my own holes for the j brackets, they went on without an issue. Unfortunately after several hours of adjusting the wall brackets and different things with my projector I still can't get a properly squared off image, one of them is always a little off. Completely demoralized and giving up for today.

Here's a link to some photos I took of my on-the-cheap velcro panel system for 1.85:1 movies:

http://photobucket.com/steel_breeze_projector

I have larger panels for 1.33:1 which attach in the same manner. It looks pretty "MacGuyver" when the lights are on, but when the movie's playing it looks terrific! Even my wife, who was initially skeptical, admitted that it made a big difference on 1.85 and 1.33 movies.

No, maybe I should have,but it was the weekend, and I knew I wouldn't have enough time to deal with it during the week, plus I would have wound up doing it this way anyway most likely. Last night I finally got it set up perfectly though. Took three tries to get it just right, plus had to attach an extra strip of drywall behind each bracket to raise the frame off the wall, i also had a piece of decorative molding that was just barely making the screen bow before I did that (it would have been harder to take the molding off). The projector shelf was the main culprit the last time, but extensive fiddling fixed that.

Watched parts of Casino Royale and Dark Knight on this last night, paired with the ae4000 this is an unbelievably nice screen. I was floored with how great it looked both pq-wise and aesthetically. Criterion 104" in Brilliant White

Happy Thanksgiving all!

Was out of town all last week/weekend. Chris, my Carada actually just arrived and I mounted it yesterday. 126 inch 1.78 Criterion pared with a JVC RS15 PJ. I could not be happier. I have yet to tweak any settings but the picture is awesome. I am a newbie to PJ's/screens but I don't see any issues with the brightness. I think it goes great with the JVC and my theater etc.

As for my Carada experience: Perfect! The purchase experience over the phone was very professional. My screen was shipped and arrived exactly when I was informed it would. As for the product, I can not say much more than those above. Packaged very well and of extremely good quality. Went together perfectly.

One note of advice for those yet to mount their Criterion screen: Mine came with the required two, 48 inch mounting rails/brackets. You mount one centered up top for the screen to slide into/rest and the other holds the bottom frame section to the wall. The instructions inform you to measure the actual height / dimensions of the screen and subtract 1/2 an inch. This measurement is then the distance between the top of the upper bracket and the bottom of the lower bracket. I used the side frame rails for this measurement (I now wonder if I should have taken the measurement once the screen was fully assembled from top to bottom center etc.).
Anyway, I had to move my bottom bracket down 1/4 of an inch for proper install. In other words, removing 1/4 of an inch from the height would have been the ticket vise 1/2 of an inch as per instruction. I mention this not to claim the instructions are wrong but rather just my experience and "thought" for those yet to install. As mentioned, it could have been the fact of "where" I took my height measurement to begin with.

For those of you either waiting for or on the fence deciding on a screen/Carada,,, as mentioned, I'm no expert but know a quality product and have viewed many screens over the last 8 months - the Carada is impressive. I could not be happier unless they credited my CC...

Bottom line, great product at a very good price to function factor etc..

Another satisfied Carada customer here!

- Time for another movie

Cheers

Love DIY

Does anyone have a Carada BW screen 16' from a Mits HC6000 PJ? If so how bright is it. I will be moving back home next year and am planning on what to mount permanently. I plan having around 120" screen. In the process of doing all of my blocking for my ceiling mount and running my wiring I need to make sure what projector and screen will give me enough FLs.

This will be setup in my LR so it will not be bat cave. It will have black out shades, but there may need to be a light about 10' behind the projector.

hello folks - I just purchased the Mits HC6800 PJ and will arrive next tuesday at which point I will get it installed via a ceiling mount. I am going to do a 120" screen but I am really dont have a clue on which aspect ratio.... the 2.35 or the 1.78.

I will be watching live sporting events, HD TV and blu-ray on a regular basis. Can anyone point me in the right direction on what size to get?

1.78 would be my recommendation... That would give you the most viewing area for HDTV/Sports and 16/9 movies. Then just get the widest screen your room/PJ can accommodate to get the most out of 2.35 material etc.

118" 1.78 BW really filled the bill for all of your criteria for me. Then I made some DIY masking (see "my latest masking trial" thread in the DIY screens section), which allowed me to watch wider aspect ratios at their best.

The 1.78 really does give maximum flexibility.

I just bought a AE4000 and I want to move on from my old 94" to Carada BW.

My viewing distance is about 13 and half feet. Should I go for 112 or 120 inch and 2.35 or 2.40 ratio screen?

Any ideas?

I currently have a 92" BW Carada screen with the throw distance around 15'. I want to upgrade to a 120" screen and move the throw distance to around 16'. How much will I lose in foot lumens and what affect will it have on my picture quality and brightness?

I love my Carada screen, but have been looking at the High Power screens also.

I love my Carada screen, but have been looking at the High Power screens also.

The make and model of your pj has more influence on this than the screen size.

I currently have the Mits HC6000, but will upgrade sometime next year. This PJ puts out less foot lumens than the ones I am looking at (Mits HC6000 & Panny AE4000). I am concerned about the reflective issues of the High Power plus the Carada screens are cheaper.

If I remember my physics correctly, light intensity falls off with the cube of the distance.

That is not the correct relationship here. The light from the screen will change with the inverse of the screen area. The lower throw ratio will result in an increased level of light output from the projector partially offsetting the increase in area.

Assuming he backed up the projector a distance to fill the 120" screen without adjusting the zoom/throw-angle, shouldn't my physics be correct?

However, you are right in that the relationship is not quite correct for this particular case. Measured from the center of the screen to the corner, the original 15' on 92" screen gives a 14 degree angle. The diagonal increases by 14" for a 120" screen. If he only moves the projector back 12", the new throw angle would be 17 degrees (again, measuring from the center of the screen to the corner). So, in his case, the increased throw angle would make it dimmer, right? The light cone has widened.
