"Could be better, but is a solid deal for $600"4.0 starson by hypnotoad72
Pros: * 120Hz feels fluid but not gaudy
* very good black levels
* excellent color gamut, when calibrated
* yellow subpixel DOES make the warmer end of the spectrum more vibrant
* limited edge bleed
* Quadpixel does a good job at smoothing jagged diagonal lines
Cons: * Poor viewing at wider angles (color washes out, but at least there's no hue shift)
* many people report some clouding on upper-left corner (two circular white splotches) - calibration removes most of this
* contrast ratio is disappointing for the MSRP d
Summary: The unit I got had 2 hot pixels (bluish-white), but they're not noticeable from a distance (3 feet). It's not worthwhile to exchange. YMMV, of course.
I never use wi-fi, or the internet, not for a television.
When looking at the set head-on, and calibrated, the image output is very sharp (I'd love to find out the dot pitch for the pixels). Upsampling of 480o or standard-def DVDs looks VERY good. This has to be due to enabling Quadpixel, which smooths jagged diagonal lines.
Turn off Active Contrast. (Dynamic contrast) - brighter images get brighter and darker images get even darker. It does throw off calibration as well.
Enhanced color gamut - the extra punch to the colors' saturation is nice, but I prefer to keep it turned off as well.
Colors are excellent, after calibration. As long as one looks straight ahead. From side angles, the picture becomes faded. But there's no hue shift so a VA panel, rather than TN is being used. IPS is best and, for the MSRP, I'd expect IPS to be used, but it's not a deal-breaker.
The other problem I have is that this set seems to take darker grays and show them as black - at a head-on angle. Even after calibration. If I look up or down by a few degrees, color starts to wash but the darker material become visible. This is a MINOR problem, and typical for VA panels (my previous computer monitor was VA and exhibited this as well), but worthy enough to mention. Even in TV shows, watching a police officer walk across the street, the black crush effect makes it look like a flat solid black image with head and arms. I've calibrated the set to minimize this, but this is where the set COULD do better. But it's still not a deal-breaker.
There are a TON of calibration options. Each is worth reading up on and optimizing.
When reading reviews to other sites, half of them don't provide any real details and the rest, while appearing to be technically competent, lack the level of spelling and grammatical acuity to be deemed "professional" - not to mention that one site will praise the set and the other will shrug it off entirely. But the best site of the bunch is found at flatpanelshd.com. http://www.flatpanelshd.com/review.php?subaction=showfull&id=1308733719 (they have a list of optimized calibration settings as well - definitely worth making a note of and trying out.)
They too mentions the pros and cons and, having compared example images they'd taken with others, the lower contrast ratio (meaning the darker display/crushed blacks) is indeed an issue with this set, but others have the same problem. Other sets with better contrast ratios and show it were found to have scores of other issues, so ultimately it's a toss-up: Lose out on a little contrast detail or live with more problems. I will live with the reduced contrast ratio. (and compare pics from various sets, the yellow subpixel in the Sharp DOES make a difference for warmer hues (oranges, yellows, golds, etc).)
All in all, this set is worthy of 4 stars. The idea of using a 4th subpixel is like adding extra colors to a printer to add more vibrant hues to print output, and the quality shows. Contrast ratio is slightly lacking, but is not a deal-breaker considering the pros this set has got. Ditto regarding viewing angle - despite the muted colors, it's not terribly bad and there's no hue shift and hue shift would drive me up the wall.
