Help with Projector display

I checked the owner's manual and nothing is there. Please check the link below to see the picutre.

I roughly measured the screen size and it looks like a 4:3 ratio screen.   The NEC LT380 is also a 4:3 projector.

The projected image is a 16:9 image, so I'm guessing your bluray or source device is outputting a 16:9 signal and the projector is only showing that aspect ratio.

If you want to fill the entire screen, you will need to look for a really old DVD movie that was filmed and produced in the old 4:3 format.  They are extremely rare, but it is possible.

For the white space on the top/bottom, you will just have to live with that.  In your case, it is an extreme amount of whitespace because your screen is a 4:3 screen.  Most all home theater screens are 16:9 (which is a compromise between the square 4:3 ratio and the super wide 2.39:1 ratio.

I wanted to use it but looks like I have to buy a new one.  Thanks for all your advise and help.Stay Safe.

I also had a projector that was not designed for watching movies. Therefore, I read about models that have passive 3D technology and high resolution. These are the most suitable projectors for watching movies.
