The Sharp UB30 4k LED TV has an impressive contrast ratio and handles itself well in a bright room. Unfortunately, the other aspects of the picture quality aren't as good.

Unfortunately, the gray uniformity is not as great as the black. There are multiple darker lines across the screens, which can be seen on panning shots.

The viewing angle of the Sharp UB30U is limited, and it loses saturation very quickly off-axis. It is even a problem if you are directly in front of the TV, assuming you sit close enough. For example, you can see slight discoloration on the left and right edges in all our pictures in this review.

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.

Low resolution content like DVDs looks good and not too soft once upscaled.

720p content like cable TV also looks good on this TV.

The upscaling of 1080p content is as good as with other brands.

Native 4k content looks nice and crisp.

Sound Quality

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.

6.4 Frequency Response
Std. Dev. @ 70
:
4.04 dB SPL
Std. Dev. @ 80
:
3.84 dB SPL
Std. Dev. @ Max
:
3.87 dB SPL
Max
:
85.8 dB SPL
Low-end Cutoff
:
169 Hz

The frequency response isn't too bad for a TV, and it remains consistent even when the TV is pushed hard. However, there's not a lot of bass present and it doesn't get very loud either.

5.0 Total Harmonic Distortion
Distortion @ 70
:
0.048
Distortion @ 80
:
0.079
Distortion @ Max
:
0.419

The sound is relatively clean at lower volumes, but under load, the TV will produce significant distortion. There may also be some aliasing present in the high frequencies.

Remote : Basic

The included remote control is not very good. It has none of the advantages of a smart remove (no motion or mouse pointer), but includes the disadvantages, like no numeric keypad.

Misc
Power Consumption : 61 W
Power Consumption (Max) : 135 W
Firmware : 1.2.3.2788

6.8 Mixed Usage

While the contrast ratio and black screen uniformity of the Sharp UB30U 4k LED TV are great, the poor gray uniformity and very limited viewing angle is a deal breaker. Even if you sit directly in front, you can see discoloration on the left and right side of the screen due to the incident angle. It is also not a good choice for gaming, because it has the highest input lag that we measured so far in 2015.
