With the advancement of technology, 4K resolution TVs (also known as Ultra HD or UHD) are increasingly prevalent in the market. Simultaneously, the prices of these high-resolution TVs are gradually decreasing, making them more accessible to users. So what exactly is a 4K TV? How does it differ from Full HD and HD TVs? Let's explore the answers together with Mytour Superstore!
What is a 4K TV?
A 4K TV is equipped with a screen resolution of 4K, equivalent to 4,096 x 2,160 pixels (also known as Quad Full HD – QFHD), providing four times the resolution of Full HD.

4K TV boasts four times the resolution of Full HD
As a result, on a 4K TV screen displaying 2160 vertical pixels and 4,096 horizontal pixels, equating to 8.3 million pixels, images are exceptionally sharp compared to TVs with Full HD and HD resolutions.
Differences Between 4K TV and Full HD and HD TVs

Differences Between 4K TV and Full HD and HD TVs
In reality, you can hardly perceive the difference in quality between 4K resolution and full HD resolution, especially with TV shows and Blu-ray content. Although the pixel count on a 4K TV is much larger than other standards (4000 pixels horizontally and 2000 pixels vertically, compared to 1920 pixels horizontally and 1080 pixels vertically), the ability to discern pixels largely depends on the distance from the screen.
However, when compared to HD TVs, 4K TVs clearly demonstrate significant superiority over 720p HD TVs. Nevertheless, even when watching videos at extremely close distances, the difference is not too significant.
However, both in theory and in practice, 4K TVs still exhibit far superior performance compared to Full HD and HD TVs.

4K TVs still demonstrate far superior performance compared to Full HD TVs
Here are some examples that will prove this:
- A 40-inch TV with HD resolution often exhibits all the shortcomings such as blurriness, loss of sharpness, and significantly reduced image quality, due to the low pixel count on the screen, failing to meet the requirements of a large 40-inch screen. HD resolution is suitable for budget TVs with sizes of 32 inches and below.
- A 60-inch TV equipped with Full HD resolution often shows the appearance of pixelation, indicating that the 1080x1920 Full HD resolution still doesn't adequately meet the requirements of a 60-inch screen. Full HD resolution is suitable for TVs with sizes ranging from 45 inches down.
- With a TV as large as 100 inches, users will experience incredibly sharp images thanks to 8.3 million pixels. The large screen of a 4K TV with its ample pixel density ensures seamless and more realistic images.
Leading electronics manufacturers prioritize the development of 4K TVs

Leading electronics manufacturers prioritize the development of 4K TVs
With users' demand for higher audiovisual experiences and the availability of 4K sources such as YouTube videos, streaming services, 4K Blu-rays, and standard 4K video download/streaming services, top electronics companies like Sony, Samsung, LG, TCL, etc., have intensified their efforts in advancing this increasingly popular technology. HD and Full HD TV technologies have gradually been neglected by manufacturers and receive less investment for development.

LG introduces processing power with Tru-Ultra HD Chip
It's evident that electronic companies continuously enhance and equip premium TVs with advanced image technologies and processors such as:
- The 4K X-Reality PRO image processor of Sony TVs allows users to experience HDR content directly on their TVs.
- The CEVO processor of Toshiba TVs.
- Samsung and TCL TVs feature UHD Upscaling technology.
- LG's Tru-Ultra HD chip for LG TVs
The price of 4K TVs is significantly higher than that of HD and Full HD TVs
The cost of researching and manufacturing 4K TVs is currently quite high, so the prices of 4K TVs are much higher compared to HD and Full HD TVs.

4K TVs are significantly more expensive than HD and Full HD TVs
However, in the near future, many technology experts predict that 4K TVs will decrease in price and become widespread. LCD TVs are very easy to manufacture at 4K resolution, so mainstream prices for this type of TV will soon emerge.
