I'm sure there'd be a hilarious glitch where Siri picks up the movie you're watching and does something ridiculous.

The distance you are away from the TV is irrelevant - I mean, sure, we don't sit in front of a TV at the same distance as we do from a monitor - the issue is that HD is not really HD anymore, when you have 1080p but the screen size is huge. You're seeing as much pixellation, or worse pixellation, as you did on TVs from a few years ago that weren't HD.
As for the video source, that's irrelevant too. 1080p TVs already have to upscale the picture from pretty much everything you've got. Plenty of people still have their VCRs hooked up, and I'm sure the vast majority still have their old DVD players, which I can pretty much guarantee did not output at 1080p. And then the TV signal is usually not 1080p; at least around these parts, HDTV is merely 720p, not sure about the rest of the world.
Modern HDMI technology is already capable of handling resolutions greater than 1080p. It's very odd why TVs haven't started supporting those resolutions yet.

Well, I can't speak for you but it's pretty hard to see pixellation until you're about 1.5 m from my TV (60" 1080p).
My experience with TV upscaling is pretty bad, though. before I got HDMI cables for my player, the delay between the sound and the picture was noticeable (even by my mom, which is saying something). Then again, different TVs perform differently so YMMV.
What I was saying about sources is that most things today, when released in HD are 1080p. People with a 4k resolution TV would either not have the resolution they wanted, or an upscale, which BakaBT doesn't seem to advocate unless done perfectly; something I don't expect a TV to do. If TV's were advertised on PPI, then a 32" tv and a 34" TV would have different resolutions if PPI became a standard instead of resolution. Even then, movies would still be released in a certain resolution, which probably would be higher than 1080p, but still too high or too low for most people.

That is what You only scale what you need to. if you are getting 720p or 1080i cable service output it at that dont scale it to 1080p. And never use a tv scaler, A decent scaler costs big bucks. unless you look into the marvell Qdeo and soon to be sigma VXP
I direct source anything and everything I can.

halfelite, the TV is 1080 pixels high, so if the video is 720 pixels high, then it has to be upscaled to fit the whole screen. If you don't do any scaling at all, then smaller source video won't fill up the screen; it'll only fill an area that's 720 pixels high. So if you're watching, say, a 480p dvd, then you have to either scale it up to fit the screen, or play it in a tiny corner of the screen (roughly quarter of the screen's actual area or so, I guess it would be). Which kind of defeats the point of getting a big TV.
