TVs have developed tremendously in the last two decades, and that’s the reason today we have technologies that have revolutionized the television experience. Over the years, I have seen exciting technologies come and go, and some stand the test of time.
In this article, I will describe the best technologies to look for in a high-end TV in 2021. If you are planning to buy a top-of-the-range TV, read on to know the most sophisticated features that suit you.
1. OLED, QLED, Mini-LED, and Micro-LED
These are display technologies that are expected to replace LCDs (Liquid Clear Displays) which have been around for some time now. OLED (Organic Light-Emitting Diode) provides an infinite contrast and intense color with the help of organic molecules.
On the side of QLED (Quantum Light-Emitting Diode), the display has microscopic molecules that emit light and provide bright highlights, better picture, and improved viewing angles.
As far as Mini-LED is concerned, there is the shrinking of LED modules to provide a more efficient way of achieving high brightness and improved contrast.
Concerning the Micro-LED, there is the use of many microscopic LEDs that form one lighting element. This technology is still in the development stage and is expected to offer better response time and improved energy efficiency.
2. UHD, 4K, and 8K
Developed to replace FHD (Full High Definition), UHD (Ultra High Definition) is a technology that adds more pixels per inch (PPI) to a display. It therefore provides a higher resolution and clearer picture.
4K (4000p) and 8K (8000p) are terms used interchangeably with the UHD. As their names suggest, 4K is a resolution that is four times (3840 x 2160 pixels) that of the traditional TVs while 8K is eight times (7680 x 4320 pixels). TVs with the 8K resolution are rare and expensive, but the 4K technology is still fresh and can offer enough vividness and picture quality.
3. High Dynamic Range (HDR)
HDR is a technology that expands elements such as contrast and color. It works well with TVs that have high contrast ratio and sharp color; and it provides deeper blacks and brighter whites.
There are a number of HDR formats, but the most common ones include HDR10, Dolby Vision, HDR10+, Hybrid Log-Gamma (HLG), and Technicolor.
4. Local Dimming
Applicable in LED TVs, this is a technology that lowers the screen lighting to improve the black levels. It dims dark scenes to make them appear deeper thus improving the picture quality. TV brands have come up with many dimming methods, but the most preferred ones include micro and full-array local.
5. Artificial Intelligence (AI)
Artificial Intelligence has been used in TVs for some time now. For example, there is the Google Assistant which lets you control your TV with voice commands. But AI can now improve your device’s sound and visuals. The top TV brands are using AI to help you enjoy a clearer picture and richer sounds.
6. Upscaling Processor
Commonly known as an upscaler, this is a system that improves a low-quality HD or FHD content. It increases the content resolution, contrast, color, and details making it appear like 4K content. Different TV brands have different upscaling processors, but the tops brands are the ones that are likely to have the most effective upscalers.
7. HDMI 2.1
In case you didn’t know, High Definition Multimedia Interface (HDMI) transfers audio and video content from one device to another. The new standard (HDMI 2.1) has been touted as a game-changer as it can transmit content that has a high resolution and allow faster refresh rates. The high-end TVs come with HDMI 2.1 ports to enable you connect things like AV receivers and game consoles.
8. Smart TV Platform
A smart TV platform allows you to connect to the internet and enjoy a variety of online services. With this platform, you can at least browse the internet and stream music and videos. Some common smart TV platforms include WebOS, Tizen, Roku, Android TV, MyHomeScreen, Amazon Fire TV, Vidaa U, and SmartCast.
In conclusion, all the above technologies cannot be found in one TV, and therefore, when buying the electronic device, you need to consider the one that suits you better. The top TV brands have always designed models that fit many customer needs, so it may not be difficult to find the right device for you.

I have found this article very helpful. Only recently I looked at our dated TV and wondered how we would ever choose a replacement. Your explanation of the terminology is very useful.
