If you’re looking to purchase a new TVs, there are many things you need to know before you do. Some of the most common things you need to know include the refresh rate, smart features, and the amount of pixels.

Dolby Vision

Dolby Vision on TVs can be found in most major brands including Sony, LG, Vizio and TCL. There are even some models from lesser known manufacturers that feature Dolby Vision output.

Dolby Vision is an HDR standard that optimizes images frame by frame. It improves the quality of colors, details, and shadows. In addition to this, it helps eliminate light bleeding.

The Dolby Vision logo is often the first indicator of a set’s support. Not all sets will feature Dolby Vision, but all should at least be capable of displaying 4,000 nits of brightness.

The Dolby Vision logo is also on some Ultra HD Blu-ray discs. However, the format is not widespread, especially in the consumer market.

Streaming services are the primary source of Dolby Vision content. Netflix, Disney+, and VUDU have all supported Dolby Vision HDR streams.

Dolby Vision can be found on many devices, such as smartphones, laptops, and tablets. Dolby Vision can run on legacy HDR connections, and it can be enabled through a software update.

Quantum Dot

Quantum Dots technology is becoming more common in LCD TVs. These are semiconducting nanocrystals that are used to enhance the color quality of the TVs.

Quantum dot is a light-emitting particle which can glow green and red. They have been engineered to emit specific shades of red and green. The size of the quantum dot is also important. Smaller quantum dots produce green, while larger ones produce red.

Quantum dot technology allows for more saturated colors and increased brightness on LCD TVs. It was initially used in medical imaging. However, it is now gaining popularity in commercial applications as well.

Quantum dot-enabled TVs use LED backlighting to provide illumination. They are different from OLED flat panel displays. Although they are similar, there are many differences.

Quantum dot-equipped LCD TVs are typically two sizes. One size is optimized for red, while the other is designed for green. A quantum dot-saturated sheet of film is used to encapsulate the LED.

Refresh rate

Most TVs on the market refresh at 60Hz. For a more realistic motion experience, you should look for a 120Hz TV.

The refresh rate of a TV is a bit of a mystery, since manufacturers don’t like to reveal how they get their numbers. Some have a single setting, while others let you choose between a handful of options. You may be surprised to find that a 240Hz refresh rate actually has diminishing returns. However, if you’re serious about watching fast-paced action, you might want to consider one.

For the most part, manufacturers have gotten much more consistent in the past few years. If you’re looking for a 4K television, you’re probably going to want one with a native panel refresh rate of at least 120Hz. In the future, we can expect more of the same from Samsung and TCL.

In addition to displaying more frames per second, you’ll also enjoy smoother motion. That’s because modern 60Hz TVs use a telecine technique known as 3:2 pulldown. It creates new frames by combining data from surrounding frames.

Smart TV features

A smart TV is a television with built-in internet connectivity. It offers an entertainment experience that is not possible on your computer. Some of these features include web browsing, music and video streaming. There are also apps, voice control and other capabilities.

Smart TVs are available from most major brands. They offer a variety of features for a wide range of price points. Many of them use proprietary operating systems, such as Samsung’s SmartCast, LG’s WebOS system, or Roku’s Amazon Fire TV platform. The user interfaces vary by brand, but most come with a home page.

Most of the newer models have a voice search feature. This allows users to search for content that is currently playing on the television. Users can also get weather, celebrity gossip, stock prices and other information. These voice searches can be accessed from the remote or on a mobile device.

Streaming services are a must. With the Internet Protocol Television standard, TVs can deliver a wider variety of shows than traditional network and cable lines. Netflix, Hulu, MLB TV and Pandora are some examples. Several of these services are free. Others are available for a subscription, and usually cost less than a cable bill.
