Reader Ralph writes in and asks: Does 480p and 16:9 Really Match? If a video game is 640x480 which is obviously not 16x9 how is the image 16x9? So is it some behind the scenes TV work that is going on ...
1080p scaled down, without a doubt. It contains much more data, so once you scale it to 480p it looks like super-sharp uncompressed video.
