> Though, actually generating that many pixels might be hard when you have nowhere near enough memory. Even if you don't have enough memory or CPU time to render true 720p, it's nice to be able to output 360p or 240p inside a 720p container with each pixel and line duplicated two or three times. Doing it that way gives you nice crisp pixels rather than the blurry mess the displays internal upscaler would probably produce. You can even insert blank lines to get a faux-CRT-scanline effect.
