Could you find me a TV with a tuner that does not have a Coaxial input?
You did not say "The tv had no tuner" However without a Coax input there is a 99% chance the tv does not have a tuner. And there is a margin of error of +/- 1%
Hey look, when I was a kid (I am only 33 now) I had a black and white TV in my room that had two or four little screws for an external antenna connection. The TV had its own tuner with a dial, 2-13 and a second dial for UHF 14-69. When rigged to coax with a special RF adapter from Radioshack, I was able to get cable of all things on channels 2-13. This TV had a tuner, but could only be relied upon to tune the lower channels. This TV, while common in the 1950's and 1960's did not have a coaxial connection, yet it had a tuner. This TV was a TV, not a monitor. And if you are my age or older (my wife is only 28 and she had one too) you should remember having one of these old TVs in your room if you were lucky enough to have a TV in your room as a kid or teen.
My point being, that while coaxial may have been a universal tuner input type in the United States for antennas, cable, etc, over the last 20 or more, it does not mean it is the only connection type and is not required to have a tuner in the set. The connection type feeding the tuner, and the tuner itself, has made many changes over the years. So, when I read that there was no coaxial input on these newer TVs, my immediate thought was that there is probably another, newer standard connection type that I have not yet heard of. You don't honestly think that we will always use coaxial connections do you? That will change as certain as the day will turn to night. I am no expert in the field of coax, tuners, and up and coming connection types, but I would certainly not put it past them to come up with a new "protected" standard. Look at cablecard. That is one of the newer connection types. I am sure there are others on the way, as well as improvements to cablecard.
While I find it unusual that there is no coaxial input. I realize that my sense of normalcy isn't the standards bearer.
But back on what I first said, I doubt any store would make a big enough mistake to put a bunch of (computer) monitors out there on display with a big sign HDTV and think what they had on display were TVs. Usually, in the small TV section, they have a stack of boxes above or beneath the display, where if you want to buy one you can just grab your own box. Well, seeing as the display had six or seven "screens," wouldn't one think that a manager, worker, customer, SOMEBODY, would realize that none of the boxes said TV or HDTV and they all said things like "widescreen display monitor," "monitor," and anything else but TV? I find that very unlikely. Very unlikely.
Perhaps you are right that she didn't turn these TVs around far enough to see a coaxial input. That is a more likely scenerio than the storekeeper labeling seven models as TV when they had no tuner.
OK... I am ready to bury the hatchet now. haha. Please stop trying to throw egg on my face. This whole argument is stupid and neither of you have "proven me wrong."
