The C9 series delivers a justifiable price tag alongside all the same excellent OLED picture quality.

Best Overall
LG C9 Series

LG's C9 is our pick for the overall best 55-inch TV money can buy.

For the last several years, LG has specialized in premium OLED TVs. Starting with the C7 OLEDs in 2017 they've been our favorite TVs every year–for very good reason, too!

If you haven't heard, OLED displays are some of the best in the business. Each pixel turns "on" and "off" automatically, so when OLED TVs display black, they display actual black. Likewise, when they display a color, it emits from the pixel directly, giving it a more pure and unfiltered appearance than the color of traditional LED/LCD TVs. LG's been the leader in OLED TV production for several years, and the 2019 C9 is almost the most affordable one in the lineup.

The C9 series (which is also available in 65- and 77-inch sizes) delivers a justifiably high price tag alongside all the same excellent OLED picture quality, 4K resolution, HDR and Dolby Vision specifications, plus LG's friendly "webOS" smart platform. It's full of great features and a wide selection of calibration options for AV nerds who feel like tinkering with their TV settings. Check out our full review of the LG C9 series for more information.

Vizio M Series Quantum

The 2019 Vizio M Series Quantum offers a taste of quantum dot performance for a price most people can justify.

Best Value
Vizio M Series Quantum

When it comes to new 55-inch TVs that pack a ton of value, it’s hard to top the 2019 Vizio M Series Quantum (M558-G1). This outstanding, affordable TV offers a taste of quantum dot performance for a price most of us can manage. It's not the best 55-inch TV you can buy, but it's certainly the best value.

The M Series Quantum doesn’t get quite as bright as 55-inch TVs in higher price brackets, but that doesn’t mean its contrast isn’t impressive; the TV’s brightness and deep black levels come together nicely on the full-array panel. Colors pop, too, thanks to the M Series’ quantum dots.

One caveat, however, is the M Series Quantum’s native refresh rate of 60 Hz. This might be a dealbreaker for folks who need super fast response times while using gaming consoles or who watch a lot of sports: y'all might want to hunt down a 120 Hz TV instead.

Although we love the 55-inch model (M558-G1), it's worth noting that the M Series quantum is also available in a wider variety of sizes than its closest competitor, the 2019 TCL 6-Series. All in all, it’s a great 55-inch 4K TV for anyone looking to upgrade to a dependable HDR TV without breaking the bank.

Our lab is outfitted with much of the same equipment you would find at a factory that manufactures and calibrates televisions.

The Testers

Reviewed has been testing TVs since some of its current employees were in middle school. While many proud TV testers have come and gone through Reviewed's labs, the current Home Theater team consists of Michael Desjardin and Lee Neikirk. Michael is a senior staff writer and a six-year veteran of the Reviewed tech team. A film enthusiast and TV expert, he takes picture quality seriously but also understands that not every TV is a good fit for everyone.

As Reviewed's Home Theater Editor, Lee doesn't do as much testing these days. However, he designed the company's current TV testing methodology after receiving calibration certification from the Imaging Science Foundation.

We measure things like peak brightness, black level, hue, and so on.

The Tests

It'd be an understatement to say that we're serious about TV testing. The lab in our Cambridge location is outfitted with much of the same equipment you'd find at a factory that manufactures and calibrates television.

On the hardware side, we've got things like a Konica Minolta CS-200 tristimulus color meter, an LS-100 luminance meter, a Leo Bodnar input lag tester, a Quantum Data 780A signal generator, and more Blu-rays than we can keep track of. For software, we use CalMan Ultimate, the industry-standard in taking display measurements and calibrating screens to specifications.

Our testing process is equally complicated and has been honed over many years to gather data that is marginal enough to satisfy curious video engineers, but also relevant to the average person's viewing experience. We measure things like peak brightness, black level, hue and saturation for primary and secondary digital colors, the accuracy of the TV's electro-optical transfer function—you get the idea, it's complicated.

Weighting for our performance tests is based on how the human eye prioritizes vision, which means we put "brightness" data (monochromatic eye based on light sensitivity) higher than colorimetry, which is also scaled by the eye's sensitivity, and so on.

Outside of the strictly technical tests, we also spend a lot of time just watching and using each TV, getting a feel for the at-home experience of doing things like dialing up streaming video service, connecting a Blu-ray player and watching movies, using the smart features, and checking out the TV's ports, remote, and on-set buttons—anything and everything that might be relevant.

What You Should Know About TVs

While everyone has different eyes, generally, our vision all functions the same way: we prioritize dynamic information and bright, compelling colors over subtler hues and resolution (sharpness). Generally, a TV can be considered a good TV when we forget that we're watching a TV. We don't see pixels creating mixes of red, green, and blue to simulate colors; we see the real world, lit and colored as it is, in fluid motion.

In simpler terms, this means a TV that can get very bright and dark without obscuring details; produces accurate colors (compared to various color standards designated by the International Telecommunication Union); possesses proper bit-mapping and the right codecs and decoders for video processing; and can properly play the various types of content thrown at it without judder, blurring, and so on.

Note that specs alone (pixel count, measured brightness) aren't automatic indicators of quality, much like intense speed is not automatically an indicator of a good car.

What TV Terms Do I Need To Know?

When it comes to knowing what you're paying for, almost no category is more rife with subterfuge and tomfoolery than TVs. While knowing the specs of the TV you're shopping for is only half the battle, it's the bigger half. Here are the key bits of jargon you'll want to know while browsing:

LED/LCD: This refers to Light Emitting Diode and Liquid Crystal Display. LEDs are the backlights used in LCD TVs, also sometimes called a LED TV for this reason. The LED backlight shines through a layer of a semi-solid substance called "liquid crystal," so named for its ability to morph in reaction to tiny electrical volts and allow light to pass through.

OLED: This means Organic Light Emitting Diode. This is an altogether different panel technology than LED/LCD, albeit on the surface they work similarly. Rather than an LED backlight element shining through an LCD panel element, OLED TVs essentially combine the backlight and crystal array, using sub-pixel strata that produce light and color individually.

4K/UHD: Usually 4K refers to resolution—specifically, 3,840 x 2,160 pixels. This is the current standard/mainstream resolution for most TVs. UHD means Ultra High Definition, and actually refers to a suite of picture improvements like 4K resolution, Wide Color Gamut, and High Dynamic Range.

High Dynamic Range: Like "UHD," High Dynamic Range (or HDR) refers to both a type of TV and a type of content that expands on the typical range of brightness (luminance) and color that a TV will produce. HDR TVs are newer and usually a bit more expensive, but can have four times the brightness and 30% more color production than non-HDR TVs, at least. Current HDR formats are HDR10 and Dolby Vision.

60 Hz/120 Hz: These numbers refer to what is called a "refresh rate," with Hz (hertz) meaning "times per second." So if a TV's refresh rate is 60 Hz, this means it re-scans and updates for picture information 60 times per second; with 120 Hz, it's 120 times per second. Currently, TVs only come in 60 or 120 Hz. A higher refresh rate is always better, but not always necessary.

Smart TV: The term "smart TV" has evolved a lot over the years, but all it really means is that the TV connects to the internet. Most smart TVs these days are just a way to watch streaming services like Amazon Prime Video on your TV. Some smart TVs have browsers, calendars, or even Roku or Android functions. All smart TVs have ethernet or WiFi built-in.

Quantum Dots: Quantum dots are used in LED/LCD TVs only. These are microscopic nanocrystals that produce intensely colored light when struck with light. Quantum dots can be used to vastly improve the red and green saturation of a TV, and are one way that LED/LCD TVs can match the color spectrum of OLED.

Local Dimming: OLED panels look great because each pixel can operate independently. LED/LCD TVs can imitate this functioning via a process called local dimming, where localized clusters of LEDs dim or boost depending on whether the screen needs to be darker or brighter, sometimes vastly improving their performance and worth.

What Is a TV Series?

You may notice the TVs listed in this roundup don't follow the traditional naming convention you might see in a store or online. That's because rather than nominating a single size of TV (such as the LG OLED65C8PUA, aka the 65-inch LG C8 series OLED), we nominate the entire range of sizes within a "series."

Typically these TVs are identical in performance but differ in price and size. We do this in order to offer you more flexibility in your decision, but also because it's the most accurate representation available.

Other 55-inch TVs We Tested


The LG CX isn’t quite the best 55-inch OLED TV you can buy, but it’s an OLED TV nevertheless, which means it’s currently one of the best 55-inch TVs you can own.

In true OLED fashion, the LG CX features the signature near-perfect black levels that we’ve come to expect from this premium technology. Stellar contrast is the primary reason that TVs like this look so good, but you can also expect gorgeous, vivid color production and excellent motion handling. In fact, the CX’s native 120 Hz refresh rate makes it a great option for sports fans and gamers alike—you can expect clear, judder-free motion pretty much across the board. The TVs sleek, ultra-thin design is worthy of praise, too—the CX is sure to class up whatever room it happens to occupy.

For anyone expecting top-notch brightness from their top-notch TV investment, a word of caution: Although the LG CX features some of the best contrast money can buy, its peak brightness levels don’t come close to those we’ve measured on high-end, non-OLED TVs, particularly those outfitted with quantum dots.


  • Amazing picture quality

  • Future-ready

  • Premium design


  • Expensive

  • Not as bright as competition


The 55-inch LG BX is one of the most affordable OLED TV series released in 2020, which makes it a great pickup for folks who don’t mind paying a premium for stunning, top-of-the-line TV technology, but nevertheless don’t want to spend the extra dough to land a better-performing TV, like the LG CX.

The BX is a 4K TV whose HDR support meets the Dolby Vision standard. Since it’s an OLED TV, you can expect perfect black levels and dazzling, voluminous color. For some folks—gamers in particular—the main draw of the BX will be its special features; the TV is equipped with HDMI 2.1 ports, supports FreeSync/G-Sync, and features a native refresh rate of 120 Hz. Simply put, the BX is one of the most affordable ways to secure a TV that will get the most out of the PlayStation 5 and the Xbox Series X, even if its price tag doesn’t seem very affordable at first glance.

Because OLED TVs don’t get as bright as quantum dot LED TVs—and because the LG BX isn’t as bright as higher-end OLED TVs like the LG CX—folks with relatively bright living rooms might want to give brighter TVs a closer look. The LG BX isn’t exactly a dim TV, but it’s not as bright as you might expect given its price tag.

Here’s the bottom line: The LG BX isn’t a budget-friendly TV, but it is one of the most affordable ways to secure incredible OLED performance and future-proof features.


  • Perfect black levels

  • Voluminous color

  • Incredible design


  • Not quite as bright as other high-end TVs

Sony A9F Series

In order to compete with LG’s OLED TVs, Sony's 2018 A9F Master Series needed to set itself apart. For the most part, it succeeded—the A9F is a visually striking television with fantastic, top-tier performance chops.

What it doesn't manage to do, however, is justify its relatively steep price point. You can read more about everything the A9F OLED offers in our full review, but Instead, it's a combination of the high price point and some more particular aesthetics-based flaws.

That said, this is still an incredible 4K OLED TV, and you're getting ultra-premium features and performance from top to bottom. We just don't think it outperforms the 55-inch LG C9 enough that it's worth paying more for.


  • Amazing contrast

  • Unique design


  • Software is a bit of a headache

Samsung Q80R

The 55-inch Samsung Q80R isn’t as good as some of Samsung’s more posh offerings, but the difference in cost might make it an appealing alternative for folks who don’t want to splash out completely when buying a new TV.

Being a quantum dot TV, the Samsung Q80R delivers searingly bright highlights and vivid, well-saturated colors. Its panel features a native 120 Hz refresh rate, too, which means its motion handling is terrific—a perfect fit for gamers.

The only downside here is the Q80R’s price tag, which is too high to compete with some of the more affordable quantum dot TVs like the 2019 TCL 6-Series. It’s certainly a better performing TV than the TCL 6-Series, but given the Q80R’s price tag, you might be tempted to just spring for something on the top shelf.


  • Excellent motion handling

  • Gets very bright


  • Premium price tag

Sony X950G

The X950G isn't the best TV on the block, but given its price tag, you're getting a lot of really awesome specs and features—starting with a bright 55-inch screen. It’s one of Sony’s best TVs from last year.

If you're not concerned about its narrow viewing angles and slightly disappointing color production, you're looking at a great TV that holds up well, especially in brightly lit rooms. For the most part, the X950G performs as well as it should given its price tag.

While you can check out our full review of the Sony X950G for more information, the thing to know about the X950G is that it's a good all-rounder. Performance isn't the X950G's only selling point: At this price, you're getting the Android smart TV platform and a slick, modern design, too. It's not the best value nor the best performer of 2019, but it offers a posh-feeling without a super-high price tag.


  • Great contrast

  • Thoughtful design


  • Frustrating software

  • Narrow viewing angles

TCL 6-Series

The 55-inch TCL 6-Series is a budget-friendly quantum dot TV that brings the benefits of this impressive technology (namely better brightness and color production) to a price bracket that most folks can actually afford.

We were quite impressed with the TCL 6-Series’ contrast; the TV’s relatively deep black levels look all the better thanks to its ability to get very bright. It’s also hard not to love the TV’s built-in Roku platform; it’s our favorite smart platform of all the major players, and having it baked right into the TV’s software is a blessing.
That said, it’s hard to offer a QLED TV in this price bracket without making some concessions. The 6-Series’ motion handling isn’t as good as higher-end QLED TV’s whose panels feature a native refresh rate of 120 Hz. In addition, the 6-Series’ viewing angles are quite limited.

Still, this TV is flush with value, especially if you’re hoping to land a TV that’s bright enough to hold up in a brightly lit room.


  • Budget-friendly quantum dots

  • Built-in Roku smart platform


  • Lacks native 120 Hz refresh rate

Samsung Q60T

The Samsung Q60T is a mid-range quantum dot TV with a good amount of value due to its relatively affordable price tag. It's available in a 55-inch model, but if you're looking for a little extra oomph, it's also available in a 58-inch variant, too.

With the Q60T, you’re getting exceptional contrast, superb color production, and Samsung’s built-in Tizen smart platform, all for a competitive price. All told, we were impressed with the Q60T’s overall performance despite the fact that it doesn’t get as bright as some of the mid-range quantum dot TVs we’ve tested in the last year.

On that note, folks who are shopping for a QLED TV on a budget might want to take a look at the Vizio M Series Quantum and the TCL 6-Series, both of which feature quantum-dot panels that get brighter than the Q60T.

If you’re a staunch Samsung supporter, however, you’ll find a great deal of upside in the Q60T—it’s a great 55-inch TV for those of us on a budget.


  • Affordable price tag

  • Quantum dot color


  • Doesn't get very bright despite the quantum dots

Sony X800H

The 55-inch Sony X800H is a solid mid-range TV with accurate color, impressive brightness, and dependable viewing angles. It’s a great option if you’re a diehard Sony fan, but if you’re just looking to maximize your dollar, there are better-performing TVs in this price range.

Thanks to Sony’s Triluminous technology, the X800H produces rich, accurate color and offers Dolby Vision support, making it a terrific mid-range option for cinephiles. It also gets quite bright for a mid-range TV, so if you’re planning on putting your new TV in a brightly lit room, the Sony X800H is worth a look.

Unfortunately, the X800H gets so bright that its black levels remain relatively shallow. In addition, the X800H’s native refresh rate is 60 Hz, so it’s not exactly the ideal choice for hardcore gamers.

There are better-performing TVs that offer similar peak brightness levels and comparable color production, but that’s not to say that the Sony X800H isn’t worth a look. Just keep its limitations in mind.


  • Gets very, very bright

  • Accurate color

  • Dependable viewing angles


  • Shallow black levels

  • High asking price

TCL 4-Series

The 55-inch 2019 TCL 4-Series is a great option for bargain hunters. Essentially, you're getting 4K resolution, HDR10 compatibility, a built-in Roku platform, and a 60-Hz refresh rate. Not bad for this TV’s price point.

The TCL 4-Series is one of the most affordable 4K TVs we've seen to date. Although its performance won’t blow you away, it gets the job done for a low, low price.


  • Incredible price

  • Built-in Roku platform


  • Doesn't get very bright
