21:9 4K 120 inch viewing width suggestions

hello can anyone recommend a good 4K screen for 120 inch viewing width? installing into dark room . bright lighting will not be an issue
how easy is it to build my own frame? seems like the frame is usually more expensive than the typical screen material nowadays.
anything located in Canada would be a Bonus at this point !

thanks,

If budget is a concern, I would look into building your own frame out of Poplar and using either Milliskin Spandex or SeymourAV Center Stage material for the screen itself.

7.4.4 Theater Room: JVC-RS500, Silver Ticket AT 2.35:1 142”, Onkyo RZ830, Anthem PVA-7, Panasonic UB420, Apple TV 4K, JBL Studio 530’s, Dual Driver VBSS

3.1 Living Room: Samsung 64” F8500 Plasma, Anthem MRX 300, Dynaudio Audience 52’s, Dynaudio Audience 122C, NHT SubOne, Roku Express (2019)

That would be pretty close. In home theater, screen ARs are generally expressed in theatrical ratios, so 2.35:1/2.40:1 are going to be the equivalent to a PC 21:9.

Is the OP looking to use an A-lens?

I don't see any detail either way. The majority use lens memory/zoom though.

I think he is saying that because a curved screen is generally for use with A-lenses.

Before getting into a scope screen setup you need to understand all that entails. 21:9 or scope 2.4:1 need a projector capable of doing CIH presentation. That happens with using an A-lens or with doing it with a projector that has programmable zoom, shift and focus and the projector you mentioned I don’t think will do that. There is also IMAX movies now like Dunkirk and many others that are as wide as scope only taller. That may or may not be something for you to think about once you get a projector that can do what you want.

Most people do CIW constant image width and use a 16:9 screen.
