Duh.
I just counted the vertical res (because I'm a noob and lazy), which appeared to be in the ballpark of 720 lines.
From that we can pretty much assume 720P. It's not like anybody will make a game 1600X720 or something.
It could be something like 1024X720 in theory, I'm just assuming 1280X720 is the lowest they would go on next gen hardware.
As I pointed out, my "results" are just in the range of 720P, "in the range" means it could even be 640, or 680, or 780, vertical. I'm just assuming anything close to 720=720.
Not only am I not very good, but to get closer to the true res you need more steps. And the pic quality was so blurry I couldn't really count longer edges, nor did I try very hard.
