This of course is not my first HD TV. My first was a Toshiba DLP, and it was a lamp hog. Then a Toshiba 50 inch plasma, which failed in 3 years, then LG's first 1080p 60 inch plasma (Still working great), a Mitsubishi 73 inch DLP, (Still working great), and now, the ultimate plunge with this Sharp 80 inch TV.
My viewing area for this TV is 12 feet at its closest and 15 at the farthest, and I instantly thought when I turned this monster on, that I should have stayed with the 70 incher. Oh well, it is mine and I am happy with it.
For its size, this TV is well made and looks nice. Picture quality is excellent as close as 3 feet, and then as far back as you can go. I also purchased this TV from a major retailer in Texas because Amazon would not take 2 credit cards, and G. E. gave me more 36 months interest free credit at the Texas retailer than they did at Amazon on the store card, so Amazon lost the sale. I also looked for quite awhile at the, the Sharp 70 inch, and the Panasonic 65 inch VT30 Plasma, and I chose this TV for several reasons. Overall for size, quality, and looks, coupled with its truly great picture and excellent blacks. Remember, the better the blacks, the better the color, because black is the number one color in the color scheme.
I gave this TV 5 Stars because of its numerous features and control ability with its menus. The picture is also superb, but the Panasonic 65VT30 still has a little better picture quality. LED is rapidly gaining on plasma though. Overall, I love this TV, and I will finally stop looking for awhile, because it is like being in a movie theater every time I turn it on. It also does not have the delay when turned on like the Mitsubishi DLP. The other good thing is when this TV is on all day, it is cool to the touch, where the Panasonic plasma is not.
Some settings from the calibration of my set, which I noticed was great out of the box, but it was somewhat to the red side on the tints. My calibration settings are as follows, and this was professionally done, and will help the rest of you get yours close. Mine now rocks!

These settings should get yours into the calibrated ball park, and I have messed with the Sharp line of large TVs for quite awhile, and they are all somewhat to the red side out of the box. I also would not want to ruin a perfect record of Amazon Reviews by giving this TV any less than 5 stars, because I cannot. This TV deserves and has earned all 5 stars in this rating.
UPDATE
I started having picture problems with mine the next day, and almost sent it back, but I found a loose Monster HDMI cable, and it was also defective. A new monoprice cable for 10 bucks fixed the problem, and the picture is absolutely stunning. So do not trust anything. Always check your cables, and don't pay those high prices for Monster Cables. They're not worth the price difference, and are way over priced.
Update
Mine has been on 8 - 12 hours per day, and it has the most stunning picture over and above even the Panasonic and Lg Plasma. Trouble Free, and Sharp even called to make sure I was happy with the product. I have seen the 3d, and it is good, but I my self would not want to watch 3D all the time, so I am very satisfied with this product, and I would buy another one if I had a place to put it. Read the other reviews, this TV rocks and the picture far exceeds theater quality. I also recommend the DVDO Edge Green to which I own 2. One on my Sharp 80 and one on My LG 60 inch Plasma. The DVDO is a video processor with lots of features that will enhance any picture on any TV and up convert and signal in to 1080p 24Hz, and it really works, plus it automatically switches from the DVR to the next component turned on like a Oppo Blu-ray, or DVD Player or surround sound. The DVDO Edge is the best kept secret in the entire electronic industry.
February 5, 2013 UPDATE
I am over a year now with this TV, and it has been the most enjoyable purchase I have ever made. I have not had one iota of trouble. The picture is clear, crisp and much better, easier to view, and not over enhanced like my 60 plasma. Honestly, I bought this TV because of its size, and now I realize, Sharp makes one of the finest products out there. It is all in the settings, and keeping the firmware up to date. Wish I had the money, I'd put one in every room, and now, I'd give it 10 stars.
