I was amazed it was so effective. I'll have to redesign it with some foam boards at the least but I've never had a 2:40 screen and that's what it looked like and I felt like I was at the movies.

It is awesome! Welcome to the club!

I can't get the video to work. I have a 120" 2.37:1 screen and anxious to learn how to add side masking. I'm extremely un-handy, too. Haha.

Link fixed for the video. Should be fine to play there in the thread now. Thanks!

I finished mine. I bought six rare earth magnets for $20 but could never get them working for me.

In the end, I have L brackets (upside down) that hang the top mask on. I attach the bottom using C hooks on both the screen wall and the mask panel.

So, its a little job to setup but well worth it.

I was sad to have to watch the Dark Knight Rises without the masks due to the variable aspect ratio ( the Bane of the CIH setup.)

Thanks alot for posting this. Your video really shows it. I monkeyed together my own similar system before I saw your post. I am using two eye-hooks screwed into the ends of the mask panels and then there is two screws sticking out of my soffit that I hang the panels on. Not as pretty as yours. So I am going to try the magnet idea. I am using rigid pink insulation for my panels and wrap them in blackout fabric. I tried sticky metallis duct tape but thats not doing it. What type of tape did you use with the fabric?

Super cool masking technique! I've been thinking about doing something very cheap / homemade similar to this, but I may even just copy this entirely. I used to live in a big loft but am now in a much smaller condo, and think my new projector's 16:9 mode is just too useful for games and tv shows to try constant height setup, I think constant width as you have done is cheaper since 16:9 screens are probably cheaper (are they?). Also, vertical contraction anamorphic lenses are easier to do with less side effects than horizontal expansion, so I may make myself a DIY lens setup as well. I think it's just simpler to move my projector back a bit, because I'll be at the width limit of my living room anyways and can't really use 1.33x times that, so squeezing it down vertically + this type of 2:35:1 masking system could be the el-cheapo way to get very good brightness and image quality.

thanks!

Sorry for the delay, my Subscription setting wasn't right, so I didn't see your reply until now...

Often the 16:9 are cheaper, simply due to volume of production. Yep, the vertical masking is usually easier to do - just as you stated. If you do copy this (and I'm happy if you do!) please post some pics so we can see what you create. smile.gif

I just used standard fabric tape from Joanns. I moved this last Summer, so I don't know how long that exact setup will last. It was a test design. On something more permanent, I would use fabric adhesive.

Awesome work!

My only concern with incorporating such a system is getting shadows thrown from the bottom of the top panel onto the screen as my projector is ceiling mounted more or less at the height of the top of the screen.

Have you ever had any trouble with shadows?

Cheers!

[edit]
I suppose if I set it up right, I could have the top panel only *just* out from the level of the screen, and taper the lower edge if necessary.
