The TCL Roku 49S405 does come with its own stand, consisting of a pair of triangular plastic feet. They attach easily with a screwdriver, and when attached, they make the total depth of the set 8.5 inches.

It has very good 4K (UHD) performance.
- Consumer Reports
The included remote is a standard Roku TV part, a 5.5-inch rounded black wand with a prominent, plus-shaped, purple navigation pad. The pad is easy to find under the thumb, and dedicated service buttons offer direct access to Amazon, HBO NOW, Netflix, and Sling TV.
- PC Magazine
Roku TV is simple to use and features lots of channels and apps.
- TV Review Land
It has low input lag and little motion blur, making it a great pick for video games.
In Roku OS, IPTV is available with multiple channels like Netflix, Amazon Video, and Sling TV. The user can sort channels and create own playlists.
- Help To Choose
This TV from TCL features 4K Ultra HD picture clarity with excellent contrast and color. This works well for watching movies, sporting events, and for playing video games. The TV has a 120Hz refresh rate which works to prevent lagging and blurring during fast action scenes.
- The Consumer Guide
It comes with a mobile app that expands the television service to your smartphone.
- Much Needed
It has smart functionality via a pre-installed Roku TV, which will let you install more than 4,000 streaming channels, including Netflix, YouTube, Hulu, HBO Now and Vudu. For ports, it has three HDMI 2.0, one USB, RF, composite, headphone jack, optical audio out and Ethernet.
- Lifewire
It's pretty hard to buy a new TV and not get smart features with it—built in apps, web browsers, and so on. One reason we love when companies bundle in the Roku platform is because you're basically getting a standalone Roku streaming box included with your TV.We really like the Roku platform for its simple, easy-to-navigate UI and robust selection of apps, which Roku calls "channels."

Some of the key features that you can look forward to is 4K Ultra HD picture quality and with Roku TV you will have access to loads of streaming channels. It is made with direct-lit LED with a refresh rate of 120Hz along with HDMI, USB and HDCP inputs.
- Tech Gear Source
Great contrast ratio when you think of the price.

What experts didn't like
4K resolution and HDR don't deliver a substantial improvement in image quality.

The backlighting has unwanted shadows. The edge-lit panel had some trouble with backlight consistency.When I viewed a single-color test screen, it was easy to see that the corners were darker than the rest of the picture, though the difference was subtle.

Slight backlight non-uniformity.
- Consumer Reports
Roku TV remote doesn't have enhanced features.
- PC Magazine
Remote is too basic and does not offer private listening or voice search capabilities.
- TV Review Land
Unfortunately, though, its viewing angle is quite narrow, and it doesn't get very bright, making it less suitable for well-lit environments.
The UHD resolution and HDR don’t provide a significant improvement in image quality.
- Help To Choose
Colors can be a little dull.
- Much Needed
Keep in mind this unit is one of the most budget-friendly 4K TVs on the market and as such, it won’t offer the highest-quality picture.
- Lifewire
The TV is clearly geared for HDR playback out of the box: its reference brightness even in non-HDR modes is about the same as in HDR modes, and—nerd alert—the "blue push" present in the picture quality during SDR playback is a vestige of the TV being calibrated for higher brightness and the HDR electro-optical transfer function... adjusts glasses.

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.

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 three excellent budget-friendly buys in the top 4K TVs, there are also spendier versions. They start under $500 for the budget-friendly TCL 55S517 55-Inch 4K Ultra HD Roku Smart LED TV, $600 for similar TCL 55R617 55-Inch 4K Ultra HD and $750 for the Vizio P Series 55-inch. The splurge version is the Samsung QN65Q9FN FLAT QLED 4K UHD 9 Series Smart TV at $3,000 for the 65-inch. At that price, the Samsung delivers much more than a standard TV viewing experience. In fact, it includes a new Ambient Mode, which displays decorative content, useful information, personal photos or background music to blend with and enhance your interior décor.

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.

DYWM Fun Fact

Most televisions 50 inches and larger available for sale today are 4K. However, this high-definition resolution and massive size wasn’t always the norm. The earliest televisions were very primitive in comparison. RCA began selling the very first television sets and broadcasting regular programs back in 1939. These had 5-by 12-inch (12.7 by 25.4 cm) picture tubes.

Television technology has progressed by massive leaps and bounds since the early days. Still, for decades, the primary resolution used to describe TVs was the vertical resolution. The switch to 4K, or horizontal resolution, only came in recent years.

Even now, not all content will come in at 4K level. There isn’t any U.S. broadcast TV at this level yet. However, you can find 4K content in from many streaming services, like Netflix, Amazon, iTunes and Vudu. You can also access 4K content with Ultra HD Blu-ray players and gaming consoles, like the PS4 Pro and Xbox One X.

What you can expect in the future is even more shifts, including increases in pixel resolution and more innovative technology. No matter what, the future of TV viewing is getting clearer and crisper with each new innovation.

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.
