Is it possible to force my HDTV to *not* upscale?

As in, if I'm receiving a 480i signal, I could just have the active screen portion be smaller to match, instead of it upscaling to 720 (or 1080, but in this case 720(actually I think it's 1366*768 or something, dunno why they don't just make the damn things 1280x720)). As in, there would be "pillar boxes" on all sides of the screen to make it effectively use 720x480 pixels, the rest being black.

480i looks awful upscaled on an HDTV, and I would gladly take a hit in screen size (720 is only 50% bigger, after all) for a nicer picture.

Otherwise I might have to break out the ol' standard def set.

I tried to search this in multiple places, but it's very hard to get a decent set of search terms or this, and I'm pretty sure it's impossible anyway, except for maybe on some specialty TVs.

You could try setting your DVD player to a 4:3 aspect ratio. It wouldn't disable upscaling but it should give you a smaller "window-boxed" image.

I actually have a DVD of a movie I like a lot that is so poorly done that I'm glad it shows this way by default (non-anamorphic).

You are correct, all modern TV's will upscale to their native resolution, period...

But the black bars on top and sides count in that "native resolution" scheme.

Tell whatever device that is generating the 480i signal to not stretch, tell the TV the same thing. There should be black bars top and sides now with an image that is effectively 480i. It may still look like crap, but GIGO...

Some TVs will not listen . . .

this setting on my tv is called 1:1. In this mode 720p and 480i stuff has black all around with a smaller picture.

You may can accomplish this by using a PIP window. One of my HDTVs has a mode that will put two 16:9 pictures side by side and if what I am watching is SD it is very close to 480 lines. Actually a bit less than 960x540 pixels per picture. And the picture appears very much sharper.
