No, I used HDMI cables
Penn, are you talking about the difference between 1.0 and 1.3 certification of the cables? The older spec said they only had to be tested up to 165MHz, while 1.3 requires faster speeds, up to 420MHz.
Heres the trick. As quoted from here, the HDMI referrred to is the HDMI group themselves, note that they expect any older HDMI cable to be able to pass the test for 1.3

But not to get into a tech discussion. My point was that a blind assembly of components as directed by the salesdrone at Best Buy could hamper the best system. Heck, most folks dont get told that the first thing out of the box in any TV install is to crank the contrast back down to normal levels. Preferaably using something like Avia Home Theatre Essentials, failing that, some DVDs have basic setup helpers.
Manufacturers set the contrast and brighteness controls way up there, becuase they dont know which sets will be pulled for floor display, and bright=better, espesically under the fluorescent lights of the store.
I was in Wal-Mart last night, they have a rack setup, near the entrance for normal stuff, as opposed to the food entrance. Maybe 8 HDTVs, looked to be all 1080P sets, apparently hooked up to a Blu-Ray player. Sadly, they went wrong somewhere, because that was NOT a 1080p display on any of them. If they are trying to convince people 1080p is just hype, and not spend money, they are doing a good job. Looked like crud.
