Re: It’s gold plated HDMI for geeks.
It's not storage that's the problem. It's transmission & quality.
Smaller size = faster transmission. But having that smaller size requires that you loose quality at the moment. In the area I work I would be lambasted if the quality was not good. And even though you are pointing out 240x320, it's not really. Yes that's the virtual size but the screen usually has more pixels than that, a lot more. You therefore if you don't want the image to look crap you have to size it for high PPI devices. At least double the size is needed and size therefore get's larger.
