I also read the Cnet review, and it did make me think twice about ordering it. But, I went to BestBuy and saw the 2 sets side by side with the same feed and both sets were set to dynamic fixed. The picture on the 847 was far superior to that of the 640. So based on that I decided to give it a try. I have learned that you can use tv reviews as a basic guideline, but you really have to see the TV's for yourself to make a proper decision.
Btw, I was able to eliminate a lot of the problems I was having with the 640 by getting my cable box replaced and making adjustments to the picture.
Received the 60C8470U today and after a few hours here are my initial impressions vs the 60C6400U that it is replacing.
First thing I noticed was that the 8470U looks and feels more expensive. It weighs 4 1/2 lbs. more without the stand and 14 1/2 lbs more with the stand. I like the metal bezel, and the swivel stand, which is not reflective. The 6400U stand is shiny and the Sharp symbol that lights up when the set is on, would reflect off of it and was annoying, at least to me.
When I turned the set on, I immediately noticed the dramatic difference in contrast. On the 8470U whites are WHITE. What a difference. I thought the whites were good on the 6400U, but this set in is a different league. I expected more contrast with this set having 2 1/2 times the contrast ratio, but I was still surprised.
Now, I also expected better sound since the 8470U has the same speakers as the 6470U, however, with an added built in subwoofer. Here is were I was disappointed, the sound is actually worse. The 6470u has down firing speakers and I thought they were ok. Not as good as my 5 year old Sharp 46", but still good enough. The 8470u has rear firing speakers, resulting is a very hollow sound. And, if there is a built in subwoofer, I certainly don't hear it.
I rented MIB3 from Redbox and thought the picture quality was very good, hard to say if it was any better than the 6400U.
I didn't have any 3D dvd's but I bought a Sony 3D BluRay player and it has apps that stream 3D content from Sony and IMAX. I have say that I had no interest in 3D and I did not buy this set for the 3D, but I was impressed with the samples I saw, and I am now glad that I do have a 3Dtv. It is a little annoying that the glasses will only charge when the tv is on. However, I thought the glasses were light and comfortable, unlike several reviews I had read which said the opposite. Also, I only had time to read the 3D section of the owners manual, but I was glad to see that it said optimum 3D viewing for the 60' set was 7.2 feet, as my couch is 7+ feet from my tv.
Now the most important reason for getting this set was to try to improve the picture quality of sports. I had a chance to watch the Miami Heat game tonight on a local cable broadcast. Even though it is in HD, the local broadcasts are never as good as the national games on ABC or TNT. I definitely have some work to do on the calibrations, but the picture was clear and the panning of the camera and the movement of the basketball was not a problem. I will get a much better idea as I watch football and basketball on national broadcasts over the next few days.
The one thing that is a little overwhelming is the number of calibration adjustments the you can make to this set, both in 2D and 3D. I tend to make as few adjustments as possible to get what I consider to be a good picture.
One final thing was after reading all of the complaints about screen uniformity issues, I looked very carefully at this screen. I have 2 areas that look slightly lighter, but can only see them when there is no content. When the screen is supposed to be black, it is black. I cannot find these spots when there is any content on the tv. So this is a non-issue with this set.
I hope this helps you make your decision.
