Technology is constantly developing and you want to upgrade to the latest devices? However, when you start checking them out, you realise they are no better than your old devices? The same things happen to some of us when it comes to 4K screens.
What is 4K in brief?
The pixels of 4K monitors are much more than those of the 1080p resolution. To be specific, 4K refers to one of two high definition resolutions: 4096 x 2160 pixels or 3840 x 2160 pixels which are 4 times the pixel resolution of 1080p (1920 x 1080 pixels).
In case you didn’t know, in 2017, only small or cheap TVs are still produced with a 1080p resolution. Therefore, even if you don’t like a 4K TV for any reason, in the end you still need to purchase one for better picture quality.
Are all those additional pixels a waste?
Obviously, they are not. As a matter of fact, the more pixels per inch a monitor has, the more pixel information it produces, which results in high-quality and detailed an images. And that means the screen will have sharper pictures, especially when it comes to very large screen.
Do you really see a huge difference with 4K resolution?
There are 2 main factors that affect your viewing experience including:
Screen size: Bigger screen having low resolution will result in blurred images. Truth be told, a 40 inches monitor with 480p resolution certainly produces overstretched and extremely blurry images. However, you cannot play higher pixel resolution videos on the monitor as its resolution is limited to just 480p; and indeed, it will not display any higher resolutions.
Pixel density: This is often called PPI (pixels per inch) or DPI (dots per inch). To calculate a screen PPI, simply do this formula: (PPI = Dp/Di) in which Dp is diagonal resolution in pixels and Di is diagonal size in inches. For example, a 21.5 inch screen with a 1920×1080 resolution will give us 102.46 PPI. Within the distance of approximately 10 inches, normal human eyes can see 338 PPI. The closer we look into the screen, the more blurry images we see.
Therefore, if you purchase a very wide screen, but with low resolution, its display still seems sharp when you sit far away; however, you will only see tiny motion pictures. On the other hand, when you come closer, the images will be blurry.
There is a research comparing the displays of a 1080p HD screen and 4K UHD screen using Netflix content. They claim the 4K shows greater displays overall. Moreover, it is indicated that 60-inches screens are the minimum requirement if you want to use 4K for movies. Of course, the bigger a screen is, the higher resolution it needs.
Below is a brief comparison between the potentials of 4K and 1080p
|Sizes||Limited today (32″ to 55″)|| Have a wide range of sizes|
(40″ to 100″+)
|Content Availability||Great||Average, but growing fast|
What does 4K benefit us?
In fact, people’s demand is inexhaustible. A couple of years ago, we tend to use small screen TV sets, monitors, cellphones; however, as time pass by, we expect bigger screens. As a result, manufacturers have to apply 4K technology to to provide us with enough entertainment.
Moreover, companies including Netflix have been producing 4K movies. If we don’t purchase an integrated 4K screen device, we cannot see these films with full quality. And not only does 4K give us better movies watching experience, it also benefits us in other ways including:
- A 4K TV often grants you full access to the most advanced connectivity and visual specs
- Most 4K TV use advanced technology to improve picture’s brightness and contrasts such as WCG or HDR, or local dimming
- Because of 4K’s potential, manufactures are thinking of reducing the prices of 4K film camera and TV
- Gaming will be more realistic with 4K technology
All in all, although 4K screens are new to most customers, they are truly worth the upgrade as they are trendy and have a lot of potentials. Especially, in the era of Industry 5.0, our demand of technology will increase dramatically and we will need to have a display having great capabilities.
