All right so the raster on my trusty old NEC 9PG+ is set beautifully to resolve the aspect ratio that some people may refer to as 16:9. When I set it up I figured sure, this would be the sweet spot. I can still send some 4:3 and some 2:35:1 content into the pj and not create some horrible wear on the tubes. That was before I actually owned a single Blu Ray. I kind of acquired the projector and Blu Ray at the same time and now I'm thinking I made a mistake. I'd say 90% of my HD movies are cropped/filmed at 2:35:1 and I think I played 1 4:3 movie through it so far.

I'll start by asking why? Why is this extreme aspect ratio deemed necessary for modern movies? And now I don't know if setting the raster to that ratio is worth it. I mean, that's getting a little thin isn't it? Let's see, 2:35:1 = 4:1.7, so almost half of the 4:3 tube face vertically is not being used. What aspect ratio do most people have their CRT projectors set to?

Most have it set to 16x9. The 2.4 will fall into it. it depends on your screen aspect of course.

Here is a novel though that has been brought up before. Move your 2.4 aspect up or down in the raster, then when that wears in move it
to the unused portion. Double tube life If you can make it fit.

That's a good idea. Just wondering how close to the edges is it safe to go? I know smaller raster means you can run it closer to the edge, but how close is that? Next thought, that would reduce the light output and soften the image right?
