Overview

As one of the most affordable of all of Samsung’s 4K ultra HD TVs, the 55 inch UN55HU6840 offers a somewhat more leanly equipped but nonetheless great 4K home entertainment package that still delivers everything you’d need in your 4K TV without getting weighed down by cost-increasing frills and extra features.

The HU6840 may lack some of the unique extra technologies of its much more expensive cousins the HU5880 and the curved-screen HU9000 but it still comes with all four HDMI ports, USB connections, WiFi connectivity and the full 3840 x 2160 pixels of resolution. Of course, it also comes with the full Smart TV package and on this Samsung isn’t known to shirk on quality regardless of the TV’s entry level price.

The Good

At 55 inches, the HU6840 is far from being a truly big-screen TV but that doesn’t stop it from delivering a genuinely excellent 4K entertainment experience that doesn’t disappoint. The 55 inch TV screen is no slouch at this and it nicely fills out a smaller living room or den space.

While the frills and gimmicks of its more expensive 4K cousins may be missing in the HU6840, all of the essentials for an excellent 4K experience are indeed here and thus the HU6840 does include the contrast enhancing beauty of Ultra Clear Panel technology, the power of Samsung’s UHD upscaling engine, the core UHD dimming technology that makes the blacker shades on the TV richly dark and of course the highly flexible and quick moving Smart TV interface along with its underlying internet connectivity.

Furthermore, the TV is fully future-proofed thanks to its compatibility with the Samsung One Connect Box. This box, sold separately, connects to your TV itself through a single cable and offers a full line of connection ports that are built into it.

Because the box is separate from the TV itself, it can be replaced as new connectivity standards come out down the road, thus keeping the HU6840 ready for the latest technology for years to come.

The bad

The Samsung HU6840 is definitely not one of Samsung’s higher level 4K TVs and it shows in a number of little ways. For starters, it lacks the same much higher clear motion rates of its more robust cousins the HU5880 and HU9000.

In the Samsung HU6840, instead of 980 or 1200, the clear motion rate is only 240, affecting the speed at which rapid movements on the screen are captured for maximal clarity.

Furthermore, the TV’s speakers leave quite a bit to be desired at only 10W x 2 power with no subwoofer to speak of, but then this is to be expected for a Samsung set with this price and size.

Finally, we should also mention the low 60Hz refresh rate. 60Hz gives a reasonably smooth on-screen action flow at 4K resolution but it’s nowhere near as good as the 120 to 240Hz of larger, more expensive Samsung models. Even Vizio’s smallest 4K TV does better than this.

Final Thoughts

As a starter TV in the sphere of 4K home entertainment technology, the Samsung UN55HU6840 offers a very affordable and surprisingly feature packed package for new owners.

Furthermore, as a Samsung TV, it guarantees connectivity and compatibility with some of the best and latest 4K ultra HD content available on sale today. However, for even better savings while getting technology that’s actually superior in some ways, you could also go for Vizio’s 55 inch 4K UHD P-series model.

Highlights

Considering its very low price and “entry level” classification, the HU6840 comes with a surprising number of the same highlights as its larger, more expensive and sophisticated cousins.

For starters, just like its bigger cousins in the Samsung line, the HU6840 is designed to be future-proof thanks to its compatibility with the company’s One Connect Box. While the TV comes with its own connectivity ports for HDMI, USB and the rest, there is one port on the back of the TV which takes the One Connect Box.

This external device contains its own connection ports, much the same as those on the TV itself except that they can be changed as the box is updated whenever necessary. Thus, you don’t need to worry about the connectivity of the TV becoming obsolete in a year or two as playback and connection standards change around the 4K ecosystem.

Moving on to the next highlights, we come across a number of display technologies that really serve to make the HU6840 a more robust entertainment system then you’d expect it to be:

For starters, the HU6840 has the same Smart TV and 5 panel Smart Hub interfaces as all of Samsung’s latest and best models. This means that, despite the low price of this introductory 4K TV, you don’t lose out on access to apps, content viewing options and smart TV flexibility in any meaningful way. Furthermore, the same S Recommendation engine that Samsung adds to its higher-end TVs is also a part of the Smart TV functionality of the HU6840. This technology intelligently analyzes your previous viewing habits to create a customized menu of suggestions for programming, games and apps that you might enjoy.

Then there is the Quad Screen Multi-Link feature of the HU6849. This technology lets you transform your TV into a multimedia powerhouse of four different screens, each displaying their own distinct content in 1080p Full HD resolution.

Finally, we move on to Smart View 2.0 and Screen Mirroring. These two technologies work together to provide you with the same feature going in two different directions: Smart View lets you take whatever is on your TV screen and cast it to other display devices throughout your house through an NFC connection.. This means that you can watch your favorite Netflix content, VoD programming or live TV shows from the TV on your smartphone, tablet or PC/laptop.

Screen mirroring works in the opposite direction and lets you cast whatever you have on your mobile devices to the TV’s much larger 4K screen. Thus, if you find a cool YouTube video in 4K on your phone and want to watch it in native resolution, just send it over to the UHD screen of your HU6840.

Visual Specs

On the level of visual specs, the HU6840 once again almost completely matches the abilities of its more expensive relatives in the Samsung line of 2014 ultra HD TVs.

It comes with full Ultra HD 4K resolution, offers the same high quality UHD upscaling engine that can turn HD or even non-HD content into something that looks better than Full HD and it offers a number of other high-end display features as well:

First of all, there is the Ultra Clear Panel Technology, which enhances contrast between bright and dark by making obscure areas of the screen much more richly black while clarifying bright spots without creating glare between the two. The overall effect is a much clearer, even stunning viewing experience when the screen is being watched from close to perpendicular angles.

Then there are features like UHD Dimming and Wide Color Enhancer Plus. The first of these uses a precision algorithm/scanning technology to carefully dim parts of the screen according to what kind of content it’s displaying; in the process it virtually eliminates the halo effect that tends to surround dark areas on the display. Wide Color Enhancer Plus, on the other hand, creates a broader spectrum of colors that comes closer to simulating the original color effects intended by the directors of a movie or show when they were filming it. This means a much richer, more realistic viewing experience.

However, in contrast to its more expensive, better equipped cousins like the HU5880, HU9000 and HU7250, the Samsung HU6840 has a very low clear motion rate 240 setting for clarifying fast action on the screen. Furthermore, its refresh rate is just 60Hz, half the refresh rate of the other TVs mentioned above. This means a notable decrease in the smoothness of fast movement on the screen.

Finally, features like PurColor and Precision Black Local Dimming are lacking in this particular model. The frist of these further enhances the color realism of content and the second augments conventional UHD Dimming technology for even richer black levels and brighter whites.

Connectivity

Connectivity on the UN55HU6840 is just as good as what you’ll find on any other Samsung 4K TV we’ve reviewed recently (the HU5880, HU9000 and HU7250). The TV comes with WiFi, WiFi Direct, Bluetooth, Ethernet and Four HDMI 2.0 ports for maximal connectivity to third party media devices. It also comes with 3 USB ports and the usual array of other connection ports like Component, mini jack audio out, RF in, Component/composite, optical digital audio output.

Furthermore, the Smart TV platform of the HU6840 gives you a fully equipped web browser and direct access to a wide array of streaming multimedia and social networking apps.

With the One Connect Box attached to the TV (sold separately) you get access to and even more robust range of connectivity options for HDCP 2.2 enabled HDMI and USB.

Pricing

This is definitely Samsung’s most affordable 4K UHD TV from the entire line of 2014 TVs. Despite its fully modern connectivity features and broad selection of high-end technologies, this 55 inch 4K TV sells for only $1,099 on Amazon.com.

Not so Great

There are a few things about the Samsung UN55HU6840 that aren’t so great but when you consider its extremely low price, these seem fairly minor and you’re still getting an excellent deal on this particular 4K TV.

However, the weaker visual specs like a 60Hz refresh rate and a lack of the better color enhancement and local LED dimming technologies will be noticeable if you compare the display on this TV to that of a pricier Samsung model.

Positives

• Excellent price for a very robust piece of technology
• Full Smart TV and Smart Hub
• Good visual specs
• Full connectivity
• Excellent UHD upscaling engine
• Access to full array of third party 4K content

Negatives

• Lacks some of the top-tier visual specs of pricier TVs
• No full-array LED backlighting
• Low refresh rate
