What Is a 4K TV? How Does It Display Better Picture Quality?


As the name says, a 4K 120Hz TV is just like another TV but comes with a 4K resolution equal to 3,840 horizontal and 2160 vertical pixels. This ultra-high-definition TV gives much better, clearer, and improved picture quality than any standard TV with low resolution.


Resolution refers to how many small dots are on your screen: the pixels are connected to make a display. The image you see on your TV screen result from several pixels put together. So, a higher pixel count means higher resolution. The "K" in 4K means Kilogram. Therefore, a 4K TV refers to a TV that can achieve a horizontal resolution of about 4,000 pixels.


Besides compatibility and display, if there’s one thing that sets 4K 120Hz TV apart, it is no other than the refresh rate. Generally speaking, the refresh rate is the numerical expression used to tell the number of times an image changes on your TV. Since every TV is different from the other, the number may vary from TV to TV, mainly depending on a number of factors. The higher the refresh rate, the better the picture quality.


4K 120Hz TV offers a refresh rate of 120Hz to let you enjoy a cinematic-like experience in home comfort. As a result, the high refresh rate keeps the images still by reducing the motion blur so you can have sharp, clear, and top-notch picture quality.
