There are ways to achieve arbitrary upscaling without loss of information (e.g. FFT-based). It would be interesting if TVs out there utilize such methods or if they scale using some simple interpolation scheme.
- obtu 15y agoTVs have ASICs that do that, see this subthread: http://mjg59.dreamwidth.org/8705.html?thread=254465#cmt254465 http://mjg59.dreamwidth.org/8705.html?thread=254465#cmt25446... But it's only possible with a signal designed for perfect scaling. Computers send cripser signals that are designed for no scaling at all, and the transformations hurt those signals.
