Type of 4K Smart Tv:

There are plenty of different screen types out there, all working in different ways to produce the same results. Each technology has its own unique strengths and weaknesses, so here are some basics to consider when looking for the right 4K TV for your needs:

LED TV: Direct LED

These displays are backlit by an array of LEDs (light emitting diodes) directly behind the screen. This enables localised dimming – meaning immediately adjacent areas of brightness and darkness can be displayed more effectively – and greatly improves contrast. LED TVs are also more power-efficient and capable of a wider color gamut than CCFL sets. Because of the extreme cost of mounting these arrays of LEDs, cheaper TVs usually use Edge-Lit LED screens over Direct or Full-Array LED screens.


With these TVs, LEDs of the backlight are mounted along the edges of the panel. This arrangement enables radically slender displays and offers superior contrast levels to CCFL, but can’t achieve the same picture quality as directly lit LED sets. However, they do come in far cheaper which is why most LED TVs out there now use this technology.


The backlighting on OLED (organic light-emitting diode) sets is achieved by passing an electric current through an emissive, electroluminescent film. This technique produces far better colors and higher contrast and also enables screens to be extremely thin and flexible. This is the holy grail of display technology and LG, Sony, Philips and Panasonic have all adopted it in their flagship sets.

Quantum Dot

Quantum Dot is Samsung’s big play in the LED TV space. With it, the brand claims that it’s able to produce more colorful pictures than LG and Sony while offering even brighter panels. LG’s Super UHD TVs all use a variation of Quantum Dot called Nano Cell, and Hisense makes a number of Quantum Dot TVs for the US and China.

FAQ about Best 4K Smart Tv

1. What is the difference between Smart TV and 4K?

Most current HDTVs have a resolution of 1920×1080 (number of pixels horizontally/vertically), which is often referred to as Full HD, while the resolution of older HDTVs is 1280×720. A 4K TV’s resolution is 3840×2160, or 4 times the resolution of full HD. … More videos are now available in 4K format.

2. Is led or 4K better?

4K LED TVs are still sharper than 4K OLED TVs due to motion artifacts in 4K OLED TVs that do not exist in 4K LEDs. THis and brightness are the only two qualiative areas where 4K LED beats 4K OLED. Longevity, Screen Uniformity, Brightness, Color Rendition are all accurate in the comparison.

3. Does 4K look better on a 1080p screen?

When you merge 4 pixels (2×2) from a 4K stream, it produces a full RGB 1080P image which renders perfectly on a 1080P monitor. That’s why it looks so much better when you view the 4K YouTube video on a 1080P display.

4. Why does my new 4K TV look blurry?

Why Does My 4K TV Look Pixelated, Blurry, or Grainy? You are watching content with a resolution lower than 1080p or 4K on your 4K TV. Your TV settings for HD or UHD contents are not set properly. Your cable used to connect 4K TV and the source devices do not support 4K.

5. What should gamma be set to on 4K TV?

A gamma setting of 2.2 is usually considered the ideal setting and though some manufacturers offer adjustments with choices such as 2.0, 2.2, 2.5 etc

6. What happens if I play 4K on a 1080p TV?

If you play 4K video on a 1080p screen, your TV will just downscale it automatically to 1080p, but if you have some cheap Chinese TV, it may just be no signal or only show 25% of the image, since 4K is 4X the resolution than 1080p.
