I would recommend two things before we really start looking too far into why I should buy a 4K TV or wait. First, I would check out how LCD TVs work, which you can do here. Secondly, I’d look into the proper viewing distance for the size of a TV, which you can find here. Thirdly, I’d look into what is input upscaling. You can find the information here. Each of these will touch base with some basic understanding of how a TV works and performs so everything here will make the most sense for you.
Without further ado, let’s get started. Simply put 4K content is content that has resolution four times the size of standard high definition content. That is 1080p content or also known as SHD.
How Do 4K TVs Work?
To understand how 4K TVs work, you must look at the number of pixels that are assigned to their X and Y axes. This number is 3840 across or on the X-axis, and 2160 up or on the Y-axis.
This means that when you multiply the number of pixels up and across, you will have available 8,294,400 pixels to assign information to. Then when compared to the 1080p (1920x1080p) standard that was before it, which has only 2,072,600 pixels to assign information to, you can see with pure numbers that 4K content is literally four times as large.
This translates into a better and more quality image for you.
Is 4K Better Than 1080p?
The first image you will see below is an image set at a resolution of 1920×1080 or at a quality of 1080p. You will see that the image produced is perfectly fine for any kind of content and any kind of TV out on the market. The image looks sharp and details are brought to a very realistic standard.
The second image you will see below is an image that is set for a resolution of 3840×2160 or that of 4K quality. You will notice large differences in the finest of details that in the prior image you did not even know could be an issue. The small hairs are refined that when normally set to a 1080p resolution would look jagged as if rendered with a chainsaw.
The most notable difference between the two images is noticed when you zoom in on them. If both are held side by side and you zoom in at the same time on both images, the 1080p’s image would degrade faster than that of the 4K’s image. This is again due to the fact that 4K content is four times the size of 1080p content.
What is the 4K TV Viewing Distance?
With all that in mind you need to know what is the 4K TV viewing distance. I’ve created a graph to easily illustrate when a 4K TV is worth it and when it is not. This because 4K quality is only worth the switch if you can actually see the difference.
If you’re still a little unsure of the viewing distance and how it works I have a more in-depth guide here.
What is the Best 4K TV?
With everything else in mind I aim to answer the simple question of what is the best 4K TV, but the question is not so simple. Most people would throw a TV at you and say this is the best. The real answer here is to dig a bit deeper to help yourself later on.
This is because like with many 1080p TVs before 4K TVs became a reality. You simply would not ask for the best 1080p TV. It was assumed that the TV was just 1080p. It became a staple within the industry.
So I ask you to ask a different question. Which 4K TV comes with the best features? Which 4K TV is cheapest? A question like these will help you find a better TV and a better deal for yourself rather than just a TV that has 4K built inside.
If you are on the fence about making the switch to a 4K TV you should not be. The change is welcomed and well worth it. All the numbers from the test results to TVs price all say to switch it up. You’ll find yourself happy with a more refreshing picture and you’re wallet won’t be too upset after all.
I hope this helps iron out some of the kinks with 4K TVs! Cheers!
