Our Top Picks

Best Overall: TCL S405 49" Roku TV

TCL has a line of the 4K Ultra HD LED/LCD TVs that offer a little something extra that is great for cord-cutters or those that get most of their TV program via the internet: The Roku operating system is built-in (no extra plug-in box or stick required). One example is TCL's S405 Series.

The Roku system offers access to over 4,500 internet streaming channel offerings, including the usual selections, such as Netflix, but also includes additional services, such as SlingTV. Via Ethernet or Wi-Fi, users can access an abundance of online TV, movie, and music streaming content without connection to an external media streaming box, plug-in media streaming Stick, antenna, cable, or satellite service (although connections are provided for those content access options as well).

For added convenience, you can share audio, video, or still image content on your smartphone and see/hear it on the big TV screen. In addition to Roku and other features, the S405 also delivers good image quality with Direct LED backlighting, HDR, and a 120Hz refresh rate.

Best QLED: Samsung QN55Q6F 55" Smart TV

With picture quality that is unrivaled at this price point, the Samsung QN55Q6F 55-inch QLD 4K UHD 6 Series Smart TV is a must-own. The real highlight is the QLED technology, which introduces over a billion shades of “Q” color, heightening color and contrast for a result that’s downright stellar with deeper blacks and colors that pop. Q HDR adds an almost theater-like experience that does even more to enhance the colors onscreen.

Beyond its advanced display, the rest of this TV is just as well-designed. The cables have been run through the stand for a cleaner look, resolving the problem of unsightly hanging wires. Q Smart also introduces a nearly-seamless navigation interface for discovering new shows or existing programming. With a large number of included options like Netflix, Hulu, and Prime Video, Samsung’s OneRemote makes program discovery easy. You can also use voice control with Bixby Voice to help flip channels or search for new programs.

Best Budget HDR: Toshiba 43LF711U20 43" 4K Fire TV

Finding a solid 4K HDR TV doesn’t always have to be a significant investment, at least as far as the Toshiba 4K HDR Fire TV is concerned. A collaboration between Toshiba and Amazon’s Fire TV technology, the TV delivers vivid visuals with deep contrasts and competitive levels of brightness thanks to its eight million pixels, along with dual 10-watt speakers with DTS sound. While the audio can fill a room, it does lack a subwoofer, which audiophiles should keep in mind.  

While one of the TV’s main draws might be its price point — even the largest, 55-inch model doesn’t crack $500 — the cost differential does become apparent in the hardware. Loading times can be slow, and the app store can be difficult to navigate and isn't as user-friendly as its rivals. However, if your main concern is finding a reasonably priced 4K HDR TV that gives you access to your favorite streaming services, this Amazon-branded TV is a strong contender.

Best Smart Features: Sony XBR55A9F 55" 4K Smart TV

When it comes to purchasing a premium 4K TV, there's more to these devices than just picture quality. The Sony XBR55A9F 55-Inch 4K Ultra HD TV not only has stunning picture and sound, but also a wealth of smart features that will satisfy any techie you know. These features include built-in Google Chromecast, Google Assistant on the TV to help you find things, voice controls with Amazon’s Alexa, Sony SideView connectivity so you can control the TV from your iPhone or Android smartphone, and screen mirroring with Miracast-compatible devices.

On the back of the unit, you’ll find four HDMI inputs, three USB ports, and one composite video port, so you can connect all your smart devices. If those features aren’t enough, you’ll also love that the XBR55A9F has fantastic sound with Sony’s Acoustic Surface Audio+ technology, which pushes the sound out from the direct center of the screen. While this TV is certainly a splurge, the price tag will be worth it to those who want to future-proof their TVs with all the best features.

Best Curved Screen: Samsung Q7C 55" 4K Smart TV

Curved Screen TVs were getting a lot of hype a few years ago, but consumers haven't warmed to them as much as was anticipated. However, there is still some demand, and Samsung is happy to oblige, at a high price. One example is their Q7C series. The sets in this series provide the same feature set as the above listed Q7C flatscreen set, including Quantum Dot-supported color display, and HDR10/HDR10+/HDR+ capability with highlight output.

The Q7C series also includes control via Voice Interaction, as well as the ability to send audio to compatible Bluetooth-equipped soundbars and headsets. However, just as with Samsung's other QLED series TVs, a stand or wall mount is not provided, so add that cost your budget. The Samsung Q7C Series Series TVs come in the 55 and 65-inch screen sizes.

Keep in mind that curved screen TVs in the two available screen sizes are best for 1-to-3 person viewing, as sitting within the curve provides the best viewing experience. If you have a large family, it is best to opt for a flatscreen TV.

Best Design: Samsung UN43LS003AFXZA 43" Frame Smart TV

Wall mounting a TV is definitely a popular option, but one of the main problems is that even though it looks great when you have it on when you turn it off, it just becomes a big, black, rectangle. However, Samsung has a solution: Frame TV. What makes the Frame TV different is that in addition to its traditional TV features (LED lighting, 4K resolution, HDR, and built-in smart features via Ethernet or Wi-Fi, it provides two added bonuses.

The first bonus is that its frame is customizable so that it blends in with any decor. You can frame the TV screen with wood, metal, or traditional black or white plastic. In addition, no matter which frame option you select the TV is so thin it can be mounted flush with the wall. To accommodate additional components, a thin white optical cable (which can also be painted to match your wall color), attaches the TV to an external connection hub that can be hidden out of sight.

The second bonus is that in addition to the decor-friendly design, Samsung also includes access to an online art gallery that turns your TV into a display for great art when you aren't watching TV. You can also display your own photos as well. With the Samsung Frame TV, you can say goodbye to that big black rectangle hanging on your wall.

What to Look for in a 4K Ultra HD TV

LED/OLED - Depending on the television you're looking to purchase, it may advertise that it either uses LED or OLED technology. The two offerings are different ways of lighting the screen, and LED has served as a reliable way to produce a great picture. However, if you want to take your viewing to the next level, OLED televisions do offer much higher contrast ratios with stunningly vibrant colors.

HDR - High Dynamic Range (HDR) isn’t exclusive to 4K televisions, but many manufacturers are beginning to integrate the technology as standard. TVs that advertise HDR compatibility can showcase brighter, more vivid imagery that isn’t possible on standard sets.

Smart features - Don’t have a streaming box such as an Apple TV, Amazon Fire TV, or Roku? If you intend on streaming online video services, make sure that you either pick up one of the available media boxes or ensure that your new television offers the features built in.
