HDMI, and so far (all of three days, I picked it up on the 4th) it's glorious!
I watched a couple of fansubbed episodes of a Korean TV show we like, it was awesome to see it big after having only watched it on the 22in and despite being a SD recording (640x352) the upsacling pixelation was unnoticeable from a rational distionce (like 4 feet away), I got a bit of refresh waves while playing Torchlight but didn't have too many issue with C9 except for some eye strain (still a bit of waves but not as bad as torchlight).
now it's hooked up to the PS3 and shit looks phenomenal, so I think it was mostly that AMD has got some crappy HDMI ports on their cards.
I tried taking some more pictures of my desk (minus the TV) to show off my arsenal a bit, but my cellphone takes shit indoor pictures and looking at them made me feel dizzy (they looked ok on my phone, not so good when I uploaded them), so I guess I will just brag about my desk bit for the desk-nophiles in the audience: solid oak (not a bit of press-board or cardboard to it), hand assembled, it's gotta be at least as old as I am (32), 5 feet long x 2.5 feet deep, the top of it is an inch thick, and is the best $35 I ever spent.
yes: thirty five dollars.
I got it at a local thrift store and picked it out because it seemed solid and had a large top since I can't stand cramped desks, getting it up the stairs was a total bitch (taking out the draws before moving it would have helped) but once I got it in and started cleaning it up my jaw literally hit the floor (I was crawling under it so it wasn't that hard). This thing could probably sell for thousands if it had been in a regular furniture store, even the pen cups in the center drawer are 100% oak and hand assembled.
