The Sharp LE757U is firmly in the good-enough category. It produces a big image, and probably won't break, but against its peers and even the company's own TVs it isn't that competitive. Two things hurt it: light black levels and an overly blue cast. The Quattron's blacks can't hold a candle to the cheaper LE650's and its shadow detail is also not as accomplished. Color is undersaturated compared with even the other Sharp and the set's reproduction of secondary color cyan is almost nonexistent -- with our tests suggesting a bluer hue reminiscent of the, another Quattron-equipped TV.

Black level: The very dark "Harry Potter and the Deathly Hallows: Part 2" made plain the problems with the LC-LE757U when it comes to delivering both true blacks and shadow detail. During the mountaintop sequence, wherein the camera whips around Voldemort and his amassed army, the Sharp struggled to pick out any detail and the scene was obscured in blue-black cloud. The cheaper Sharp LE650 showed more detail in the figures and also the shape of the rock they were standing on -- something that was obscured on the LE757U.
The deeper blacks of the cheaper Sharp imbues pictures with a greater sense of depth and its superior shadow detail means you can see more of the intricacies in the darker scenes of darker movies. The LE757U has a slightly crushed look to shades nearest black. During the shot when Voldemort orders the attack to begin, for example, it looked flat and stripped of details like the clothing on the "soldiers" in comparison with all the other TVs in my lineup. There was a TV worse than the Sharp for pure blacks, though, for despite its excellent shadow detail, the LG plasma's gray blacks made its pictures look less solid.
Color accuracy: The colors of the Sharp LE757U were both visibly bluer and less saturated than the other TVs in the room. At first I thought it might be a calibration issue, but the same problems persisted even in the default movie mode.
In "The Tree of Life" (Chapter 5, 37.18) as the mother relaxes on the grass, her skin looked gray in comparison to on the other TVs and her dress looked blue where it should have been cyan. This may not sound like such a big deal, but cyan is increasingly used in feature films and shows like CSI as a lighting effect. If your TV can't reproduce it you're not seeing the scene as the director intended you to.
While the Samsung 6400 also has a little color desaturation going on, it doesn't suffer from the blue cast the Sharp has, nor does it have a problem with reproducing cyan.
As an aside, the exceedingly expensivealso had a problem with reproducing cyan, and both it and the LE757U are based on Quattron LCD panels. Draw your own conclusions.
Video processing: The Sharp LE757U turned out a competent performance in our suite of video tests, only erring a little on one part of the 1080i upconversion test. The television exhibited more flickering in the Film Resolution Loss Test test pattern than on the other TVs -- including the LE650 -- but was very good on the subsequent slow pan of the stadium, with no moire and no jerking. The 24p test from "I Am Legend" was free of pulldown errors and the screen was also able to get a high 1,150 lines of motion resolution with the AquoMotion 480 mode enabled. Gaming performance was a little lackluster in comparison though, with an average of 58.1ms lag with Game mode enabled.
Uniformity: While the cheaper LE650 has no visible issues with black uniformity, the LE757U does. The sample I received had large bluish blobs that shone through on a completely black screen. If you watch a lot of dark material these "blobs" could become distracting.
In addition, the LE757U has a very shallow sweet spot. You don't have to get very far off-axis to make blacks go blue -- you can do it sitting in your seat and moving your head. When completely off-axis the screen coating also takes on an "oil slick" look and colors desaturate even further.
Bright lighting: When viewed in a bright room, the color black presented by the LE757U isn't solid and is much bluer than the LE650. But the television was only a little bit more reflective than the LE650, and was able to reject some light reflections and was much better in this respect than the ST60.
Sound quality: While you may not have a say in where the TV is placed, I found it gave the best sound about 2 feet from the wall where the so-called "proximity effect" meant that the subwoofer was able to fill in the bottom register of speech quite effectively. Bass response wasn't as flatulent as with the Panasonic ST60's speaker, and vocals were quite clear and present. Sound quality was very similar between the two Sharp TVs though explosions had a little more impact on the LE757U and a little more ambient detail was available too. I didn't get to test the 70-inch or 80-inch in this series but the addition of a 15W subwoofer should boost these sets' bass capabilities even more.
3D: The default 3D mode (Standard) is incredibly blue, we're talking Smurfingly blue. Even switching to Movie doesn't make it less likely to wear white trousers and live in a red mushroom house. There were 120Hz errors (haloing) and a lot more ghosting or cross-talk than on the Samsung 6400. In sum, this Sharp set doesn't showcase 3D to anywhere near its full potential.
