You can scale to any point, up or down. This is being done all the time. I'm surprised you don't know this!

I don't want to pick a fight here but resolution is definitely fixed. Sure, you can scale up to large sizes with a loss of quality. You cannot take a 480 line picture and convert it to 720 or 1080 without loss of quality. Or, should I say, the low-res quality remains the same but it's bigger so that poor quality is more noticeable.
I work in the graphic arts business. Customers are always providing logos to us that come from their websites at 72 dpi. When we ask them for a higher resolution logo, they say "just scale it up!" I'm sorry, but it doesn't work that way but it's hard to convince those customers.
Since you mentioned it, I'll mention that I hate the stretch feature available on most widescreen TVs. On mine, it's called "horizon." The center is almost normal and the sides are stretched way out of proportion to fill the screen. It looks horrible and almost makes me dizzy. The TNT-HD station often shows old NTSC movies in 'horizon" mode and calls that HD! What a bunch of nonsense.
