Audiovisual content, also known as 4K resolution or UHD, is already everywhere, but with the announcement of 8K as a future resolution, I wonder if the smallest screens used on laptops are best suited for this. It comes to mind. Are there any future notebooks or restrictions?
Images displayed on monitors and television screens are made up of thousands or even millions of points called pixels. Pixels are words derived from the English dimension “image elements”, each of which has RGB color information. From that particular point on the screen.
We do not glue the face to the screen. When using virtual reality devices, a low density and very strange process occur. At low resolutions, the distance between pixels creates voids that make the image slightly sharper. The particles are coarse.
On the other hand, if you sit in front of the TV, the pixel density will be less noticeable at a distance. This phenomenon depends on the distance you are looking at the screen, and the pixel density of whether or not they are indistinguishable varies. In other words, there is a limit to the density of pixels that can be displayed.
Retina display concept
When Apple introduced the iPhone 4 four years ago, its main novelty was to increase the screen resolution of the device by 300 times, the same XNUMX pixel/inch resolution used in the professional printing world. Was to achieve. ..
The image quality of smartphones has improved significantly and has been copied throughout the industry. Obviously, this figure shows that the screen is 10-12 inches and 25.4-30.48 cm, which is the optimum density for use. Smartphone, portable console, or tablet.
However, in the case of a PC, the distance is slightly larger. Of course, not everyone mounts their desktops the same way, but the pixel density per 220 inches used as a reference is about XNUMX. This makes no difference at higher pixel resolutions, as in theory, you can’t see too many pixels.
4K issues on laptops
This raises an important question for us: Is resolution above 4K feasible on laptops? I’m currently writing this article on a laptop with a 1080 inch screen at 15.6P resolution. In other words, the density is 141.21 dpi, so there is room for improvement in screen resolution.
If you can increase the screen resolution to 1440p, the dpi will be 188.28, but what if you increase the screen resolution to 2160p or 4K? Therefore, the density is 282.42. The same problem occurs with a 17-inch screen and a density of 300 dots per 259.17 inch. In any case, there is still some margin before reaching XNUMX dpi in the printing world.
But what happens when you move to a resolution above 4K? Already at 5K resolution, it exceeds the XNUMX dot limit per 300 inches. This makes most pixels indistinguishable to the eye, wasting a lot of time rendering those pixels and moving them apart. To reach a point where improvements can be seen in other parameters such as refresh rate, image quality, and even color depth, rather than resolution.
