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.
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.
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 native contrast ratio is good.
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 THX mode has good calibration by default, although nothing exceptional. See more details here.
The white balance is really easy to calibrate, but the colorspace controls are not as accurate.
You cannot control the color gamut directly with this TV. 'Movie' and 'THX' modes are based on the limited Rec.709 standard, while the other modes have the wider gamut.
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.
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.
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.
To enable the reverse 3:2 pulldown without interpolation, set 'Film mode' to 'Standard'.
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.
Chroma 4:4:4 is supported in PC mode. For 4k @ 60hz @ 4:4:4, set the input HDMI range to 'Full'.
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.
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.
Good distortion levels at low volumes, however there is a significant jump in distortion under heavy load.
