Sharp Aquos LC-40LE810UN LED LCD HDTV
A 40-inch TV with a zany twist: yellow pixels. With a modest cost and Netflix streaming, we really wanted to like it.
Motion performance was good, even without applying the optional Motion Enhancement setting. Images blurred somewhat as they moved across the screen, and there was some stair-stepping at their straight edges. This occurs because the TV may have laggy processing. This sometimes led to horizontal lines breaking up the image at set intervals. This was probably the biggest problem with motion on the Sharp LC-40LE810UN, however. It was relatively smooth and free of artifacts. More on how we test motion performance.
3:2 Pulldown & 24fps
Few TVs can playback 24fps sources without doing a 3:2 pulldown to convert it to the 60fps they normally display. This is true for the Sharp LC-40LE810UN as well, but it did a commendable job in its conversion. There was very minor flickering of high-frequency patterns after the Film Mode was set to "Standard," and no serious problems with footage of a moving stadium. There are two more options for Film Mode, "Advanced (High)" and "Advanced (Low)." Both must use a completely different algorithm, because they caused a yellow blob to appear over the high-frequency patterns we used. You might try them out for watching movies which won't standardly contain complex patterns, but they may or may not give you a better result than "Standard." More on how we test 3:2 pulldown and 24fps.
Setting the Sharp LC-40LE810UN to not overscan is handled in the System Options menu, under View Option. View Mode should be set to "Dot by Dot." Once this adjustment is made, the resolution looks great. However, every TV has its quirks, and this one had a strange issue where it blurred some colored squares, but not others. More on how we test resolution scaling.
As with many televisions, the Sharp LC-40LE810UN loses its option to not overscan in 480p. As a result, 5% of the picture, horizontally and vertically, will get cut off. There were no problems with Moiré (Moire) or high-frequency patterns, and text legibility was good, despite appearing somewhat splotchy at smaller font sizes.
For 720p resolution, the option to not overscan changes its name from "Dot by Dot" to "Full Screen." The resolution also prompted more problems with scaling, and the Sharp LC-40LE810UN exhibited minor, consistent problems displaying Moiré (Moire) patterns, such as faint plaiding, or displaying the two-pixel pattern as a repetition of leaves or spikes. 720p also caused problems with high-frequency patterns, whose alternating white and black lines appeared as being of different widths, even though they should be the same thickness. Legibility took a drop from 480p, as well.
Hopefully, most of what you should be watching on your TV should be in 1080p, its native resolution. This size had no problems whatsoever with Moiré (Moire) or high-frequency patterns. Legibility remained high for fonts down to a small size, at which point they became blurry, but still readable.
