While the Sharp UH30U 4k TV is not exceptional at anything, it is an all-around good TV. Its main flaws are the oversharpness of upscaled content and the loss of color at an angle.

Design

Curved : No

The bezel is very thin on the Sharp UH30U 4k TV. However, even if it is Sharp's highest-end model, it feels a bit more like a mid-range TV from a build quality standpoint.

The two feet stand can be used in two positions.

Stand

We used the closer stand position, which had a footprint of 34" by 14.5" on our 70" LC70UH30U.

7.2

Picture Quality

This is a good TV for movies. The blacks are pretty deep, and quite uniform. There's also no judder when playing 24 fps movies.

You don't get some of the advanced features seen in other 4k TVs, like local dimming, HDR, or 3D. If you don't care about those and just want good, basic picture, this is a good buy.

The TV has a feature named 'AquoDimming', but it isn't local dimming. Instead, it is simply a software-only smoothing feature.

The gray uniformity is decent, for an LED TV. It has no major vertical banding or dirty screen effect problems.

As usual for most LED TVs, the colors lose saturation when you watch it at an angle. You can still see the picture, but it doesn't look as great as directly in-axis.

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.

When we first got it out of the box, it had major flashlighting in the corners. Fortunately, they mostly disappeared after a few days.

The white balance is really easy to calibrate, but the colorspace controls are not as accurate.

7.0 480p Input

Low resolution content doesn't look too soft but is over-sharpened when upscaled to the native 4k resolution, even when the sharpness setting is set to the minimum. Some people might like this, but it is unfortunate that you cannot remove it

7.0 720p Input

Cable TV and other 720p content looks okay on the Sharp UH30U. Unfortunately, 720p content is also over-sharpened.

8.0 1080p Input

The upscaling of 1080p content is as good as with other brands. Blu-rays also suffer from the over-sharpening, which shouldn't need it.

10 4k Input

Native 4k content looks very good on this TV.

Its semi-gloss finish is good at handling direct reflections. There is no rainbow or glare around bright objects.
It can get brighter than the average TV, and should be good enough for any type of room.

Pixels
8.4

Motion

There's not much blur, so the fast movement you get with sports will look fine.

There's also not too much of the patchiness you can sometimes see when there is a panning shot on the playing surface. This is a very good budget TV for sports fans.

7.8 Motion Blur
Response Time
:
11.3 ms
Overshoot
:
18.1 ms

On one hand, the response time of the pixels is really fast on this TV. On the other hand, the overshoot is really long on dark to bright transitions. Therefore, on average, the motion blur on this TV is good, but not exceptional.

Inputs

The performance for gaming is likewise good. The minimal amount of blur means movement will look good, and there's most people shouldn't notice any delay between performing an action in a game and seeing it appear onscreen.

Under Game or PC mode, the input lag of the Sharp UH30 is 46.2ms, which is average. It shouldn't be a problem for most gamers.

Sound Quality

The sound is pretty accurate at a quieter volume, but is less so when the TV is made to go louder. There's not much distortion when the TV's volume is low, but there's a lot more with louder volumes.

In terms of maximum loudness, this TV is quite capable. The bass is also pretty decent.

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.

7.2 Frequency Response
Std. Dev. @ 70
:
3.04 dB SPL
Std. Dev. @ 80
:
4.04 dB SPL
Std. Dev. @ Max
:
6.10 dB SPL
Max
:
91.2 dB SPL
Low-end Cutoff
:
89 Hz

The frequency response is good at lower volumes, but progressively worsens as the volume increases. At maximum volume the response is poor and pumping may be present. However, the loudness and low-end are pretty good.

4.8 Total Harmonic Distortion
Distortion @ 70
:
0.008
Distortion @ 80
:
0.038
Distortion @ Max
:
2.771

Good distortion levels at low volumes, however there is a significant jump in distortion under heavy load.

Smart Features

Smart OS : Android
Remote
Remote : Smart

Two remotes are included with this Sharp TV. The fancy touch remote is better than Sony's equivalent for Android, but it is not as good as LG's or Samsung's.

Misc
Power Consumption : 97 W
Power Consumption (Max) : 214 W

7.2 Mixed Usage

The Sharp UH30U UHD TV is a good overall TV, especially if you don't mind the over-sharpening on upscaled content or the limited viewing angle.
