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.

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.

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.

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.

Additional Review Notes

Aquamotion960

The Sharp UH30U 4k TV has a backlight strobing mode called 'Aquamotion960'. It clears up the motion, but it dims the screen and introduces flickers.

THX Mode

The Sharp LC70UH30U is one of the few THX certified TV. It comes with 2 picture presets, THX dark and THX bright. Here are the color measurements for the default values.

THX Dark

Sharp UH30U THX Dark White Balance Sharp UH30U THX Dark Gamma Sharp UH30U THX Dark Colorspace dE: 2.66
Gamma dE: 2.11
Color dE: 2.7188

Standard

Sharp UH30U Standard White Balance Sharp UH30U Standard Gamma Sharp UH30U Standard Colorspace dE: 15.26
Gamma dE: 2.04
Color dE: 10.6121

As you can see, there isn't much difference between Movie and THX modes. The biggest difference is THX has the motion interpolation feature disabled by default.

The THX mode by default has a better calibration than most TVs. However, it is about as accurate as the default Movie mode of Samsung's high end TVs like the JS8500, so the THX certification doesn't mean much.

Is it true that the 80" version of this TV comes with Full-Array Local Dimming? If so, that would be almost a completely different set than the 70" don't you think?
Yes the 80" has a full array backlight, compared to the edge lit of the 70". However, even the 80" doesn't have local dimming, so it is not a big difference between them. The 'AquoDimming' feature is not local dimming.

Will the LC-70UH30U pass 5.1 audio via the optical audio output? Also, would ARC be required for say a FireTV to go to a sound-bar via the optical audio output?
Yes. The H30U has 5.1 pass-through via its optical out and ARC is not required.

What is HDR?
HDR means High Dynamic Range. TVs that support the feature are supposed to get both brighter and darker with sources made for HDR. Think of it at something closer to what we see in real life. That said, HDR is still in it's early days and contents are scarce enough that buying an HDR TV right now is more to future proof its viewing habits. We expect HDR TVs with full array backlight to be better with HDR materials.

To start off, this is a great website. I find myself referencing and relying more heavily on RTINGS than CNET or Consumer Reports. I am considering the 70" Sharp UH30U versus the Samsung JS8500. In a perfect world, this wouldn't be a tough decision if Samsung made a 70" version of the JS8500. There isn't a 75" version of the JS8500 but regardless it wouldn't fit in the space I have and the astronomical price jump from a 65" to 75" also makes it less appealing. The main seating area right in front of the TV is about 15 feet away. Closer seating is off to the sides of the U configuration setup. I realize I could save $$ by sticking to 1080p but at this point with Black Friday around the corner, the prices on 4k tvs have dropped substantially. In fact, both the 70" UH30U and the 65" JS8500 are currently at the same price point of $2000. Which one should I go with? Is 5" going to be a huge difference?
Usually, the bigger the better but considering the difference between the picture quality of the two TVs, the 65" JS8500 will be more enjoyable even if it is a tad smaller.

Have you actually pulled the back off an 80 inch tv? Will you separate your review into two different tv's? If you don't pull the back, I can mail you my photo's or to anyone who will help me. Isn't 458 watts vs 122 watts enough for someone to come to my aid? I can see the bulb and the vacuum seals.
Can you send us a picture? Also, can you measure the actual power consumption of your unit? Our 70" uses 214W with a backlight at max. Thanks!

Guys thanks again to this site. So i had the Vizio M70-c3 for a month. Did not like the color, the upscaling and the 90s smart TV features!
Just changed to this Sharp and its so much better in almost every way! The picture quality on the SAME exact source based on your specs blows the Vizio out of the water. Just thought I'd note that this Sharp is the way to go!
Thanks for sharing your findings! We're glad you wound up with a model you like.

Which TV should I buy between the Sharp LC70UH30U and the Vizio M70-C3?

Short answer: get the cheaper of the two.

Long answer: The Sharp LC-70UH30U and the Vizio M70-C3 are actually very similar. The difference is in the backlight and software:

  • The Vizio has a full array backlight, with local dimming. This is great for black uniformity and if you like local dimming. The downside is more dirty screen effect because the LEDs are directly behind the screen.
  • The Sharp UH30 has a wider color gamut (due to its backlight).
  • The M doesn't have the oversharpness upscaling problem (maybe it will be solved on the Sharp via a firmware update?)
  • Lower input lag on the M, which is great for gaming. The LCD driving is more aggressive on the Sharp though, which means it has a better response time, but more overshoot.
  • Better smart features on the Sharp (Android OS)

Is this a competent TV for gaming at 1080p? I am concerned that the overshoot or upscaling sharpening will introduce artifacts.
It's an okay TV for gaming, and you don't really need to worry about artifacts caused by the upscaling or overshoot. The main downsides are that the sub-par upscaling means 720p games won't look their best, and the input lag is higher than average (but still a playable level).
0
How do you upscale 1080p to 4K on the LC-70UH30U model?
4k TVs automatically upscale lower resolutions to 4k, as that's the only way they can display the video. You don't have to do anything other than watch your video.

Why is PC only 6.0/10 when the tv does support chroma 4:4:4 60fps at 4k? It seems like a perfect option for pc gamers
Indeed. It's just that the score reflects all modes listed under the 'PC Monitor' box. Since the UH30U doesn't support 1080p @ 60Hz @ 4:4:4 and 1080p @ 120Hz, the score is affected. We give 20% of the PC overall score to every modes.

Considering the LC-70UH30U but only if it may one day support HDR. I see other companies adding it. Any chance Sharp might get in the game? Thanks!
Very unlikely. Even if it does get limited HDR functionality via an update, the highlights won't be very bright, so it won't be very good.

Which is better and more reliable, Sharp 80" or the Samsung 75" I just bought the Sharp 80" (model# LC80UH30U) and waiting for it to be delivered from Best Buy. I also bought a 4yr extended warranty on it since its a large purchase and wanted to be protected. Note, you guys rated this Sharp TV with a 7.5 overall rating. My second choice was a 75" Samsung Model: UN75JU7100FXZA which you guys gave a 8.1 overall rating. When I got home I started reading a bunch of recent reviews on Sharp TVs at Consumer Reports and most of them were not good (1 star out of 5). Most consumers were complaining about poor customer support when they encountered problems like "bright dots" forming in the screen and one guy simply moved his TV to another floor and started having problems with lines on the screen. Here's the link: www.consumeraffairs.com/home_electronics/sharp_tv.html) Also, I learned that in Aug 2015 a Chinese company called Hisense bought out Sharp and from the sound of it Hisense doesn't have the best reputation and is trying to "break into the market to compete with Samsung and LG". Here's link: www.consumerreports.org/cro/news/2015/08/sharp-exits-the-u-s-tv-business-what-you-need-to-knwo/index.htm So, with all these complaints and now Sharp selling out to Hisense I'm starting to wonder if I made the right decision by going with Sharp 80" vs Samsung 75". Since both TV's were the same price I decided "bigger is better" and purchased the Sharp 80". FYI, This will be our "main" tv and will get a lot of use for general tv, sports (Supercross) and movies. I also just signed up with DirecTV in order to get real 1080p coming into the house (I was with Time Warner Cable and my monthly bill was getting too high and I think they only push 1080i) What do you guys think about Sharp's reliability issues and this new Hisense company? Thanks in advance and appreciate any and all feedback.
For now, we don't have any data to be able to rate the different brands reliability but since you got a 4 year extended warranty there is nothing to worry about. Customers feedback are good indications of how well a product or company is doing on the market but that may not always be much representative. It has to be seen how Hisense will fare in the market in the following years but for now, you can be worry free and enjoy your TV. As of the cable providers, they are diffuse in 720p or 1080i. 1080p is for movie on demand.

The 70" is edge-lit and different cabinet, stand, thickness, power, border, etc. My 80" says 468 w, the same power as my 65" vacuum florescent Sharp. My set looks like my 65", in back, like vacuum florescent. Are you sure this set is LED? Vizio 80" is 122w. Where does all the extra power go, above the same functioning Vizio power? Thank you. Clyde S.
Yes, it is really an LED TV. Almost all LED TVs leak white lights from the back. You can't really look at the power consumption rating of TVs. They are basically useless because they almost all cheat with their energy stars picture mode. Also, the luminosity of the screen has the biggest impact in power consumption, so it depends on which value of 'Backlight' you selected. A TV with a higher max luminosity will consume more power when set at max, but if set lower, it will consume the same as another TV with a lower luminosity.

I had a sharp lc600 60" led tv that went bad and i replaced with a lc70uh30u. For some reason i think that the 60" had a crisper vibrant picture quality. The new sharp seems to be a little dull with the colors and washed out with white. What gives? Is the difference in the upscaling? I needed to get a 70" because of space that it could fit in. The 60" was too small. Also, do i need to turn the sharpness down all the way because the upscaling over sharpens? Any other recommendations for this set? Thx again and keep up the awesome reviews.
Try our calibrated settings and see if you like the picture better. For a more vivid look change the 'AV Mode' to 'Standard'. Since this TV oversharpen all resolutions lower than 4k, leave the 'Sharpness' setting to 0. For cable TV, turn on 'Digital Noise Reduction' to clean up the picture from unwanted noise. Let us know if that help.
