Ok Black, I get what you're saying but not everyone is the same. Some see a wider range of colours than others, some hear differently (women tend to hear the higher frequencies and guys the lower). But what you're paying for is the ability to produce those images. If the panel cannot produce pure black, then you'll never see it.
As for the rogers signal quality: that's just it. With digital, it is either there, or it's not. It is either 1080p, or it isn't. There is no inbetween.
For eg: you often see a pixellated image. That is because of a poor signal. You won't however get a greyed out image, or ghosting, or a fuzzy picture like the old days of transmission.
A great example is Battlestar Galactica. You see the ships flying through space. With a low contrast ratio the black of space will look grey, not black. Same as the ships. They are reflective so they should be white. On low contrast panels they won't be pure white with shades of grey in between.
Then you get into black. I know on my plasma with a high contrast ratio I often see pixellated black because it can't produce all the various tones of black being sent to it.
A good analogy is;
A bugatti veyron vs a smart car. You may not often need to get to 100 kph in 3 secs. but when the occasion arises, it is good to be able to do it when you need to rather than settle for zero to 100 in 12 secs.
As with everything: if you aren't that fussy about the quality of your screen, save the money. But I on the other hand, think: if I'm going to spend $1000.00 on a screen, $400.00 for a blu ray player, $2000.00 or more on a surround sound system, $30.00 and up for Blu Ray discs, I do NOT want any shortcomings in any of the components.
The thing most people DON'T do is shop around and be ready to pounce when the right deal comes along. I was shopping for a flat panel and got pricing online, in stores, viewed the images etc and had an idea of what I wanted and how much it would cost me. I sure wasn't going to pay $1800.00 for the plasma or lcd I wanted. I just shopped, watched and waited. I was at the sears warehouse looking for power tool deals and saw a plasma screen sitting there. I walked over and took a look at it.
Here's the details: retailed for $1799.99. That day they had a no pst no gst sale. They had a 5% discount for energy star compliant items. It was open box so it was marked down to $1299.99. It was missing the remote so the guy took $150.00 off. I also negotiated a better price so when all was said and done, I got it out the door and into my truck for $950.00.
Moral of the story is: watch, learn and wait. They strike when the deal is hot. I saved about a grand. (btw, he found the remote after I paid so I ended up with hit anyways).
