Right now 4K is the standard for today’s TVs, but is high resolution superior to Full HD? Next, we will tell you Is 4K worth it and advantages over a Full HD.
4K vs Full HD: resolution isn’t everything
First of all, we have to know what are 4K televisions and which are Full HD. So we must begin to ask ourselves this question: What is 4K and Full HD?
Anyone who buys a television these days can hardly avoid reading the word 4K tied to the word television. But what is the advantage of 4K over Full HD? In which cases is 4K or Full HD worth thinking about? Are there situations where a supposedly lower resolution has an advantage?
What is 4K and Full HD?
The terms 4K and Full HD represent television resolution: the number of pixels of which the image is composed. With Full HD, the image consists of 1,920 x 1,080 pixels, and with an Ultra HD TV, the number of pixels is doubled vertically and horizontally; thus, it is 3,840 x 2,160 pixels.
This resolution is correctly called “UHD” or Ultra-HD, but “4K” is more common in general. The jump from around two to over eight million pixels (from Full HD to UHD) means that a 4K TV can deliver much sharper images.
4K resolution doubles horizontal and vertical pixels compared to Full HD. In total, we can say that it offers four times more pixels to the screen. That is, on a typical 55-inch TV, a Full HD image already looks comparatively grainy and out of focus. In contrast, 4K content looks sharp even from a relatively short distance from the screen, and the higher resolution especially shows its full potential.
The distance from the seat to the TV is one of the deciding factors when deciding between Full HD and 4K. For example, if you sit more than three meters away from the TV, the difference between Full HD and 4K UHD resolution can hardly be recognized, even by eyes that are well accustomed.
On the other hand, if the sofa or armchair is halfway from the TV, getting a sharper picture is much more remarkable.
Therefore, the resolution advantage decreases with increasing distance from the image.
Does a 4K TV have advantages in larger living rooms compared to a Full HD model in the same format?
It’s not that easy! Because in addition to a higher pixel density from the jump from Full HD to 4K, it has many more advantages. The most significant is the HDR video, which means High Dynamic Range, which means greater image dynamics. In practice, HDR encoded film material allows for a significantly higher brightness range and deeper colours than the traditional SDR format.
For many TV fans, HDR standards like Dolby Vision and HDR 10+ are the real reasons to get 4K TV. And it is that the most modern 4K televisions, almost always support at least the basic HDR formats HDR 10 and HLG (Hybrid Log Gamma). The more complex solutions Dolby Vision and HDR 10+ can also be found more and more frequently.
In contrast, Full HD TVs are excluded from the benefits of HDR content. For the most modern displays, such as OLED panels or future solutions, such as mini TVs or even micro LEDs, Full HD resolution will practically no longer play a role.
4K televisions generally come with easy-to-use and powerful Smart TV sets, through which it is possible to access 4K streaming services such as Netflix and Amazon video directly. And while the newer Full HD TVs are inexpensive, they are mostly ill-equipped.
So is 4K worth it?
Buy a 4K TV if your budget allows. With TV like this, you can watch some of the series and movies on Netflix and play PC and Playstation games with a resolution greater than 1,080 pixels. Indeed more content becomes available every day. Also keep in mind that the services offered by 4K will require high-speed broadband, which necessarily implies a higher cost in terms of connectivity services.
Lastly, remember that a cheap 4K display may be a bit more expensive than a decent 1080p one, but it may have worse components or other specs, such as a lower refresh rate, higher lag, and worse colour reproduction example.
