What is 4K?
The best 4K TVs have over 8 million pixels in their panels. That’s 4 times as much as you’ll find in a Full HD TV.
Even if you don’t watch 4K content, the resolution still offers advantages. Many modern 4K TVs have upscaling technology to make movies, series and games in a lower resolution look better.
Another reason 4K has become the standard is console support. The PS4 Pro , PS5, and Xbox One X and Xbox Series X all have 4K gaming capabilities.
Should I buy a 4K TV in 2022?
4K TVs, on the other hand, are cheaper than ever. The influx of 8K has made 4K panels more affordable and accessible. In addition, the latest consoles, such as the PS5 and Xbox Series X, have little to no support for 8K.
Some TVs, like Sony’s A90J, are still pricey. Still, there are plenty of 4K TVs to be found within every budget.
What types of 4K TVs are there?
There are many different types of monitors available. They all work in a different way to achieve the same result. Every technology has its own strengths and weaknesses. Here are the basic techniques you will encounter:
LED TV: Direct LED
With these televisions, the screen is lit directly from the back by a series of LED lights (light emitting diodes). This allows you to locally dim the light, making some parts of the image brighter and other parts really black. Thanks to this technique you have a fantastic contrast. LED TVs are also more energy efficient and can display a wider color gamut than CCFL TVs. Due to the high costs of mounting these rows of LED lights, most LED TVs use the Edge LED technology.
LED TV: Edge LED
With these televisions, the backlight lamps are not placed behind the screen, but on the edge. As a result, the screens can also be a lot thinner. They still have a lot better contrast than the CCFL screens, but the image quality is less than with the Direct LED technology. However, the price is a lot more attractive, which is why most TVs use this technique.
The backlighting of OLED (organic light emitting diode) televisions is achieved by sending a current through a conductive, electroluminescent film layer. This technique produces a much better contrast and nicer colors. It also allows televisions to become extremely thin and flexible. This is the Holy Grail of television engineering. It was not until 2014 that the first large-format OLED TV appeared on the market. It is new, expensive and the best brands are still busy making the most of its possibilities.
At the moment it is difficult to predict where we will go with the use of the self-sufficient quantum dot LEDs. What we do have is Samsung’s Nanocrystal filter, based on quantum dot technology to get a significantly better color palette and contrast levels that approach the peak performance of OLED.
