Something I've never entirely understood about AV enthusiasts is the way they can't bear to leave part of the screen unused. In particular, if they have a high resolution display, they insist on upscaling images to fill the whole screen. Question is: why? You can't possibly get any more detail into the image by doing this, no matter how good the scaler is. Sure, it's bigger, but it's also blurrier. Why, I find myself wondering, doesn't anyone seem to want to watch lower-definition images letterboxed, at native resolution, with genuine, right-from-the-source, 1:1 pixel mapping? If you've got, say, a 1920x1080 display, I'd have thought the best option would be to watch 720p actually as 1280x720. Standard definition does require to be scaled a little, otherwise the aspect ratio will be wrong, but even so you could scale 4:3 PAL to 768x576, and anamorphic PAL to 1024x576 and at least get 1:1 mapping vertically. This curious compulsion to fill the whole display always reminds me of people who refuse to watch 2.35:1 film transfers because they don't like the black bars at the top and bottom of the screen while it's playing.
