The Sharp LE653U LED TV is a good basic TV with a great contrast ratio and good black screen uniformity. The main downsides are the loss of color saturation at an angle and the poor gray uniformity.
The colors shift rapidly as soon as you move out of axis. You shouldn't buy this TV if you have multiple seating positions.
Update 01/06/2017: We have changed the methodology of testing. Since this is an old TV which we don't have anymore, we extrapolated the results from 2016 TVs.
The input lag varied a lot on the Sharp LE653U LED TV, from 30 ms to 40 ms. It was more often than not in the mid-30 range, hence our 34.7 ms measurement. Overall, it is a good gaming TV.
Note: Sound Quality test for TVs reviewed before 2017 was performed at 75dB, 85dB, and Max SPL. Starting 2017, the target SPL levels have been changed to 70dB, 80dB, and Max dB SPL.
This TV does get relatively loud, but the frequency response suffers as the volume increases. There will be noticeable pumping at higher volumes. The bass extension is rather poor.
The basic remote gets the job done, and it is better than the one included with the pricier Sharp UB30U.
