It delivers the goods wonderfully on vibrant HDR color. This is especially useful because this model also supports Dolby Vision HDR, thus letting it actually show you a decent flow of the color range and highlights that Dolby delivers to the right kinds of 4K TVs that it’s present in.

The TCL 5-Series has a wonderful contrast ratio for an LCD/LED TV that lacks local dimming, and it produces a bright, punchy image. The integrated Roku OS makes it one of the easiest TVs to use, and it supports every major streaming service. Gamers don’t have to worry, thanks to very low input lag that ensures the TV can quickly render the video in your favorite games with little delay. And if you watch over-the-air TV, you can even pause it with the use of a basic USB flash drive. The 5-Series also works with the Roku TV Wireless Speakers, making it easy to upgrade the audio without having to add any wires.

If you’re looking for a big screen on a budget, the TCL’s Roku-enabled LED TV fits the bill. Since Roku’s current catalog offers more than 500,00 movies and TV episodes, your viewing choices are extensive and easy to access through this TV’s built-in interface. Other apps like Netflix, Hulu, Pandora, and YouTube are also available to meet all your streaming needs. And if you’re tired of clicking through endless menus to find what you want, don’t worry — this TV comes with a voice control remote, so queuing up your favorite show is as simple as saying the word.

The TCL 55S517 is capable of superb color coverage, reaching 94% of the DCI-P3 gamut which makes it ideal for HDR imagery. Accuracy out of the box hits an average of Delta E 2.3 which is fantastic for a TV, but you can tighten it down to DE .5 with a more ideal color temp setting via the TCL Android or iOS app. Frankly, this TV is one of the most user-friendly options out there when it comes to adjusting the screen, making it a suitable choice for the non-technically-inclined.

However, a pretty obvious gap between the border bezel and the first line of pixels on the screen.

It doesn't get very bright—even during HDR content. Also, the internal speakers are kind of a bummer.

It has relatively dim panel. Well-lit fine details like fur and bark look clear but become slightly muddy in shadows.

VA display creates poor image quality at angles and there is no local dimming (unlike its 6-Series cousin).

The 5-Series supports HDR10 and Dolby Vision HDR, but its lack of local dimming means that we don’t consider it a true HDR TV.

An Overview On 4K TVs

Televisions have likely come a long way since the last time you were in the market for a new screen. TVs have followed the typical tech trajectory of slimming down and dropping weight while increasing screen sizes. Even if your current TV is only a couple years old, technology has skyrocketed in that time to produce incredible visual effects. That’s largely due to the introduction of 4K TVs. These 4K TVs bring along crisper, brighter and more colorful picture quality than ever before.

There are truly outstanding 4K TVs available with four times the amount of pixels as their 1080p predecessors. On top of that, they boast the latest and greatest screen technology. All of that adds up to the ultimate in viewing experiences, no matter what you choose to watch. Quite frankly, you’ve never seen your favorite shows or anything from around the world so vividly from the comfort of your couch.

But all these new and improved features can make choosing a new TV complex and confusing. There are many new numbers and acronyms in the descriptions that can sound like a foreign language to a new buyer. However, armed and ready with a bit of knowledge and a few tools of the trade, you can make an informed purchase and find the best 4K TV for you.

One of the first factors to consider is size. Measure and understand how much space you have for your TV. You’re more likely to mount a 4K TV on your wall than set it on a console, but some models have legs and can sit on a stand. It’s worth noting, these legs are generally at the outer edges of the TV, instead of in the center, affecting the overall dimensions of the stand. Additionally, TVs are measured diagonally, so take that into consideration when you assess your space and size needs.

“If you take away one thing from this guide, it’s that size matters,” Patrick Ward, editor-in-chief of the blog High Speed Experts, says. “Specifically, when buying a 4K TV, don’t hold back. The whole reason for getting a 4K TV is that you value picture and audio quality — that cinematic experience can only be achieved with a massive 4K TV.”

Now, the standard resolution is 4K Ultra HD, which offers four times the pixel resolution as previous 1080p HD. That means crisper, more detailed images. It also lets you sit closer to larger TVs without the usual image degradation.

Pixels alone aren’t responsible for the wow factor that comes with 4K TVs. For that, you need to dive into the additional differentiating acronyms. When you combine screen technology like High Dynamic Range (HDR) and Wide Color Gamut (WCG), that’s when those extra pixels really pop.

What’s more, these 4K TVs have all the features you need seamlessly integrated. They are smart TVs. That means there are no more gadgets or cords required to connect to apps, streaming services and more. It’s all in one.

The latest and greatest technology doesn’t always come cheap. While there are some excellent budget-friendly buys in the top 4K TVs, there are also spendier versions. The budget-friendly models are more basic. Then, you can quickly add on more fancy features that increase the price.  Premium TVs deliver much more than a standard TV viewing experience. In fact, some models include a new mode that displays decorative content, useful information, personal photos or background music to blend with and enhance your interior décor.

“What used to be a hefty chunk of change for folks, is now quite affordable for the majority of households,” Ward points out. “Don’t have all the cash upfront? Putting it on a payment plan can make the monthly repayments virtually unnoticeable.”

You can rest assured it’s a good time to upgrade your TV. There are always updates and new technology in the works, but the next big change to 8K resolution is still a ways off. 

The 4K TV Buying Guide

  • Remember to measure twice before selecting a new 4K TV. The screen measurements listed on TVs reflect the diagonal distance on the screen. The other measurement is the width of the TV, for sitting on a stand as well as hanging on the wall.
  • The newest 4K TVs have four times the pixels of the previous 1080p TVs from a few years ago.
  • There is new, advanced pixel technology in the works. However, it is a few years away still, so it’s a good time to upgrade to the latest and greatest 4K TVs available now.
  • The larger the number of pixels, the closer you can sit to the TV and still see a crisp clear image.
  • The new 4K TVs vary widely in price, so researching each of their distinguishing features could help you choose a more cost-friendly option.
  • The official resolution for 4K TVs is 3,840 by 2,160, so they are just shy of truly 4,000. The simplified description is much more user-friendly, so it stuck.
