That way you also get the purest, best looking image.
The OSSC does go higher than 720p actually. With a 240p input signal you can output in 240p (passthru), 480p (Line2x), 720p (Line3x), 1280x960 (Line4x), 1080p (Line5x) or 1600x1200 (Line5x) resolutions. Unfortunately 1080p isn't a perfect upscale because 1080 isn't an exact multiple of 240, so you get some cropping at the top and bottom of the screen. Personally I prefer to use Line3x mode to get 720p because it just works, it looks perfectly fine and it doesn't have any noticeable impact on lag on my LG Full HD TV.
