This tv has been discontinued.
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.
- Great native contrast ratio with deep blacks.
- Very limited viewing angle.
- Poor gray screen uniformity.
- Very high input lag, even in game mode.
The stand is separated in two feet on both sides of the TV, so it requires a wide table.

When viewed from directly in front, this TV's contrast ratio is impressive. The blacks are great.
SDR Peak 2% Window
SDR Peak 50% Window
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.
Native Std. Dev.
It has the best black uniformity that we have seen so far. No noticeable issue at all.
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.
This Sharp keeps the reflections under control.
It can get pretty bright, so you can put this TV in a fairly bright living room.
The motion blur trail is short. However, the transition from mid-white to full-white is long, which is why you can see a little bit of yellow in the letters of our moving logo.
PWM Dimming Frequency

It doesn't support 24p playback, which means movies have constant, small judder.

The input lag of the Sharp UB30U is 79.7 ms, which is very high. You will notice this when playing fast games, so do not buy this TV for gaming.

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.
Total Harmonic Distortion
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.
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.
Power Consumption (Max)
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.
Questions & Answers
10 ANSWERED QUESTIONS
The build quality on our Sharp LC-50UB30U feels cheap even compared to other budget 4k TVs. For example, you can see the LEDs inside a gap in the bezel of our unit.
Also, there is a space between the LCD layer and the backlight diffuser. This can't be seen when siting in front. If you sit at an angle though, part of the edge of the screen will be hidden, because it isn't lit from behind. Some gap is normal, but this is more than usual.
When you do review the UH30
by Sharp, will you be reviewing the 70 or 80 inch model because each model had a different panel (edge lit vs. fully array), respectively?
We already have the 70" UH30U
If you were going to chose between the M65-C1
and the 65UB30U, which one would you go with?
It depends. The Sharp has better upscaling, so it's a better choice for people who want to watch broadcast TV. The M's much lower input lag makes it the better choice for gaming, though. Both are equally good for watching movies and sports. In the end, you should choose according to your needs.
What size did you test? It's a great test but I don't see that info. From my experience different sizes can use different panel types. Or sometimes different panels in the same size even. Thank you!
The 50" (LC-50UB30U
). The size tested is the one in bold in the list at the beginning of the review.
I'm in need of a new TV, as my 67" Samsung LED DLP is dying a slow, white dot death. I'm looking at 70" televisions, so there are only a few that fit in my budget. I've been looking at the new Vizio M series
, or the Sharp UH30
. I'm holding off because I can't find many reviews of the Sharp. Is there one in your future? This review of the UB30
makes me nervous, but I would expect the flagship model to perform significantly better. Thanks.
We've just ordered the Sharp, and we should have a review up sometime in the next couple of weeks.
Will you be reviewing the new 2016 sharp 4K TV's? N7000u models
We currently do not have a schedule made for any sharp TVs, so if we do it will not be soon.
Do you have video examples of how the lack of 24p affects movie playback (constant judder sounds like a dealbreaker), or how the input lag affects things, vs. the comparable models you've listed? Also, is the input lag affected by which input you use, and beyond fast games, is it visually noticeable in other applications?
We have a video about 24p playback here
Input lag only matters for gaming. We talk about input lag, and list the input lag times of all the TVs we have reviewed, here
Will you review the 70UH30U? Very interested to see how it stacks up against the Vizio M.
Yes. We'll have the review up by Friday.
Hi. I just bought a Sharp LC65LE645U and was wondering what your thoughts on this model are, but I couldn't help but notice you have very few reviews of Sharp TVs. I was wondering why that is, and whether you will be reviewing more Sharp TVs in the future.
We haven't reviewed that model, but we are in the process of reviewing more of Sharp's lineup. Sharp is a bit lower on our list of priorities, which is why we haven't reviewed as many Sharp TVs as we have other brands.
Hello. The LC-50UB30U
has had three firmware updates since May. I was wondering if you had any plans to revisit this series to see if there have been improvements made since. I am hoping that input lag has been reduced. The latest version I believe is 1.13, released on 9/21/2015.
We don't fully revisit TVs after firmware updates but we keep all TVs for a year after we finish the review so to be able to run more specific tests. We just updated the UB30U
to firmware 188.8.131.5292 and the input lag has stayed the same.
We are not taking any more questions for this product because we no longer have it in our lab.
