A Comparative Study of 4K and 8K TV Technologies

Television is one of the oldest and ever-evolving products of technology. Technological growth has brought a revolution with new and improved televisions. There have been major innovations in televisions in recent years. One of them is their resolution.

Resolution is one of the most important criteria in television as it is more about the visual experience. 4K and 8K are the latest resolution technologies in smart television sets.

Let us have a look at both 4K technology and 8K technology to know about them! People often get confused about how to buy a smart TV. A comparative study may serve as a LED TV buying guide for you so that you can buy the best smart TV for your need! Read on!

  • Resolution

The pixel density in a TV determines its resolution. Resolution tells you how densely the tiny dots or pixels are being put together on display to create a clear image. The higher the pixel count, the higher is the resolution. High resolution improves the clarity of the picture on the screen.

4K resolution means a TV that has 4 times more pixels than a traditional TV. A traditional TV has 1920 horizontal pixels and 1080 vertical pixels. While a 4K TV has 3840 horizontal pixels and 2160 vertical pixels.

8K is the highest resolution available on a TV in India. A TV with 8K resolution has four times more pixels than a 4K TV. The pixels in 8K TVs are so small that you cannot distinguish even from close up.

  • Picture quality

4K TVs give clear images. But TVs with 8K resolution produces more vivid and detailed pictures because of their pixel density. Higher pixel density helps in producing highly detailed images.

  • Internet speed

Most of the 4K and 8K TVs are smart TVs. They need internet connectivity to provide a broader range of content. While 4K TVs need a minimum of 25 Mbps connection for streaming, 8K TVs need higher than that.

  • HDMI connectivity

HDMI is the acronym for High-Definition Multimedia Interface. It is being needed for TVs that support 4K and 8K resolution techniques. For a TV to support 4K resolution, the HDMI cables need to be of high speed. HDMI 1.4, 2.0 and 2.0a are well capable of streaming and playing 4K content.

HDMI 2.0 is capable of supporting 8K resolution. However, HDMI 2.1 is a better option for 8K content. It is the latest version of the HDMI interface and has more bandwidth, almost triple of what HDMI 2.0 can provide. HDMI 2.1 allows delivery of clearer and smoother motion through a high frame rate.

  • Cost

4K televisions are high-priced but comparatively cheaper than 8K television sets. For 4K TVs, the options available in India start around Rs. 25000. 4K resolution is available small as well as big TV screens. They come in huge varieties in different price ranges. Whereas 8K resolution TVs are costly. 8K is available only on big TV screens. The starting price of an OLED 8K TV in India is around 1099900 for a 75-inch model from Samsung. While a 75-inch 4K LED TV from the same brand would cost you around Rs.200000.

  • Refresh rate

The refresh rate is a measure of the number of times per second a TV redraws the image on the screen. It is an important feature to check before you buy a 4K or 8K TV. It is being measured in Hertz (Hz). Higher refresh rate reduces the motion blur, which occurs in an image when an object is in motion. Most of the TVs have a refresh rate of 60 Hz. The highest refresh rate in 4K TVs is 120 Hz while in 8K TVs it can go up to 240 Hz. But other factors also have an impact, and a higher refresh rate is not beneficial for all types of content.

4K TVs have become very common now. But few brands in India manufacture 8K TVs. There is a great difference between visual experiences of both the technologies.

Although 8K TVs are costlier than 4K TVs, they offer a world-class experience to the viewers. You can go through a LED TV buying guide online to know about the different options. You can also visit the websites of different brands to gather information about their products in various price ranges.

There is no doubt that 8K is the future of televisions. But 4K is not even redundant. 4K or 8K is a matter of choice, need and budget.
