I'm assuimg that stretched means "double or increase size, but lose PQ"
I'm assuming that upscale means.."double or increase size, but maintain PQ via the TV's video processor".
I probably can't give you the best definition, but in the context of how I was referring to it, is that streching is like taking a magnifing glass to zoom the picture, you are still using the same number of pixels to create the image, and thus it appears jaggy and not very crisp. If you use an upscaler, the device adds in extra pixels to the image, to help smooth out the image. The source file may be low, but the upscaler tries to improve the picture by blending in extra pixels into the image. I'm not sure if that is the "correct" definition of how it does it, but it is something to that effect.
