I got to play a few more games since yesterday, so I'll post my updated impressions here (note: I only have a 1080p and a 1080p digital projector).
Ratchet & Clank: Holy hell, this game looks magnificent. It was already a great looking game before, but now everything is pristine and gorgeous. Definitely the best looking game I've tested so far (though others have better improvements, due to their improvement on performance).
Shadow of Mordor: The game is definitely much sharper. In fact, it's so sharp that it seems to hurt my eyes. I know this sounds silly, but both times I tried playing this last night it made my eyes ache and my head hurt. That's probably more to do with me than the game, however, as it definitely looks cleaner and sharper.
Infamous First Light: A beautiful game made more...well, beautiful, and it also runs much more smoothly. Like Tomb Raider, it includes an option for higher framerates, though unlike with Tomb Raider, I actually prefer the higher resolution mode, though there is a noticeable difference in smoothness between the two. Very clean image, sharper than before, and more vibrant.
Uncharted 4: Since the game already looked so good before, it's a bit harder to spot the differences in story mode. It all looks very sharp and crisp, but it did before as well. Multiplayer, however, has received a clear resolution boost and looks much better than before.
