I'm a graphic designer, I have two LCD monitors at the work, two at home plus a 32" LCD TV, and the scenario foe-hammer described isn't anything what's happening on the screen of kiosks. Take my word for it.
First of all, you're making the wrong assumption that current LCDs would scale uneven resolutions badly. It was an issue with old notebook displays and first generation LCD displays. Current gen LCDs do the job very well, and tend to even oversmoothen the picture instead of jagging them. Wrong, wrong, wrong.
Second wrong assumption was that usual LCD resolution would be 720p. That's the past generation. All current gen LCD's are 1366x768px, including that Samsung they're using. So, that's two wrong.
Third wrong assumption was that geo22 was playing a x360 game in the 480p resolution on a 720p TV. For one thing, that's nothing like it, the resolution is much better, and man, have you even bothered to check that none of the x360 games even support 480p, they're all native 720p. MS did screw up the setup, but not that much that they'd configure the kiosks sets output 480p. Please.
For the last point, there isn't any antialiasing present on any latest screenshots released. It's not like they'd turn off the AA just for the time to snap some shots. Or does that actually make any sense to you? If it is, I'm wasting my time.
The edges on the screen are very sharp and I could've seen exactly if there was an attempt to antialias the edge, even if it was scaled wrong, but there wasn't. It was completely AA free. Period.
The problem was more with screen looking oversharpened. For those who actually know something about displays and LCD TV's (and have one back home), you can try setting sharpness (which should be set to around 50 for natural picture) to full so hard edges are over-exaggerated. Like in:

Please, don't post ignorant posts if you're trying to accuse others to be ignorant. For others, sorry for the angry post, but I just lose it when I'm insulted of being labeled biased by some ten-year-old every fucking time I try to make some valid points and have a decent conversation. So just stop it. No really, I mean it.
