So actually, 16:9 WAS overscanning, and screenfit is the one that is 1:1. Good thing I checked! So, that list above should have screen-fit for size, IF your Blu-ray or Cable box is set to output 16:9, so that it adds the black bars when appropriate.
StarHalo,
It's not quite as simple as you suggest. First gold plating is good for resisting oxidation, so it's not like it's useless! Second, the more data you squeeze through a cable, the better the construction needs to be. This relates to the dialectric/sheathing, and most of all, to the tightness and evenness of the twist of the wires inside the cable. The 1's and 0's you speak of are actually SIGNALS down the cable. Push the data-rate too high, and these signals can't be resolved into 1's and 0's because of dispersion, cross-talk, and other interferences. Third, I've purchased some cheap crappy cables (cat5e ethernet) and while they WORKED, they STUNK. Like, literally. Really bad. God what an odor! I was trying to save a few bucks and it was only 50 feet, and I was like, HA!, Amazon has a 50' cat5e for $12 (or whatever it was). But I wasted that money--or rather, I had to go to the bother of returning it. And I ended up buying a more expensive cable that I knew didn't smell bad. Some of the more expensive cables just FEEL better--the insulation is more supple, doesn't stink, has a better color, or whatever.
I agree that it's stupid to spend a lot of money on cables, but I disagree that there is NO reason to spend more than the minimum. And I also suspect that full 1080p 3D blu-ray content may actually push the data-rate up to where SOME of the really cheap cables MAY start to experience data loss. But maybe I'm wrong. Don't know. Personally, if I were buying another HDMI cable, I'd get one of the ones from Amazon for $10 and I wouldn't worry. I would NOT get one of the $50 ones from Best Buy, though! LOL! OK. Well, just my $0.02.
