Best 4K Smart TVs to Buy in 2018
Television sets have come a long way since its original invention. 2018 has brought with it a slew of brand new and high-tech televisions that offer a myriad of features at different price ranges. Getting an older model may cost a lot less nowadays with the introduction of newer models. However, you might actually be missing quite a lot in terms of new developments in television technology.
Most televisions offered by manufacturers in 2018 offer 4K resolution and HDR capabilities. These features now come as standard in large television sets that are 30-inch or higher. In fact, it is currently quite difficult to find a brand new 30 or 40-inch television set that isn’t 4K. The new standard, which also known as Ultra HD, features a resolution of 3,840 by 2,160, with eight million pixels.
4K-resolution television sets have also dropped in price in recent years and are more affordable. Some 65-inch TVs, which is ridiculously large for some applications, now cost less than $1,000. Most television sets also offer an HDR feature. Newer LCD and OLED panels currently offer this feature, which elevates user’s viewing experience. HDR greatly expands a television set’s color gamut and gradients. They also improve the range of color and light information from the source signal. TVs with HDR typically produce more color and more luminance values, which translates to eye-popping images on the screen.
With the availability of multiple streaming services, finding 4K content is now much easier. Users will, of course, need a stable and fast internet connection to take advantage of these streaming services. Most, if not all, of these services, now offer television series and movies in 4K resolution. Sites like Amazon and Netflix offer original programming that is in 4K. New movies and series aired on these sites are also available in 4K. There is also the option of watching 4K content on Ultra HD Blu-ray discs. However, this particular method will require a dedicated Ultra HD Blu-ray player or a console such as a Microsoft Xbox One S.
Television sets with “Smart” capabilities and the ability to connect to the internet have also now become a standard. Most television will have their own operating system built-in. However, “dumb” television sets can still become smart by simply connecting different devices to its HDMI port. Some popular options include the Apple TV, Google Chromecast, Amazon FireTV, and different Android TV boxes.

Compared to last year’s model, the new 6-Series also brings with it improved HD and 4K performance. It is a perfect device to enjoy movies and games, especially with its Dolby Vision feature.
