Even before its microprocessor, the first question is which laptop screen to choose. But how? On what criteria and for what use? Let’s see. This is often the first purchase criterion: which laptop screen to choose? Or, more precisely, which computer to choose according to its screen? Because, unlike a desktop computer with its famous tower, you cannot select the screen of your new laptop PC separately since it is an integral part of it.
Therefore, its screen very often guides the user a priori towards this or that model before he details the other characteristics of the laptop PC. And among the most critical points, the first is apparent, or in any case, must become so: which size to choose?
First, the screen size determines what you see (more or less), depending on your visual acuity. This value is expressed diagonally (from 10 to 17 inches for laptops, 1 inch = 2.54 cm). It directly determines the working and visual comfort, which depends on the time spent each day… precisely on the screen. Visual fatigue will be felt more quickly on a small screen, especially if you wear glasses; you must be aware of this when choosing your laptop.
Another important parameter, the screen’s size, directly impacts a laptop’s size and weight. Mobile or nomadic users need to take their computers everywhere with them. Therefore, those will prefer a compact portable PC equipped with a small screen (from 10 to 15 inches maximum) that is easy to transport.
Sedentary users who never or rarely move their laptop will therefore care little about its size. All the more reason not to deprive yourself and choose a large screen, from 15 to 17 inches, much more comfortable whatever the use, especially for wearers of glasses. The screen size weighs little on the price of a laptop, and you should know that.
For example, the differences in weight and size of Dell laptops depending on the size of the screen (in Height or thickness, Length and Depth or width):
Laptop screen technology also significantly influences image quality and visual comfort. Essentially, two technologies prevail: LCD screens and LED screens. LCD screens (liquid crystals) progressed markedly at the start of the 1990s with the arrival of the TFT or “Thin-Film Transistor” (thin-film transistor), in particular in terms of colorimetry and speed. But in recent years, new TN and IPS technologies have further advanced LCD / TFT. Thereby :
For their part, LED screens bring together almost all the qualities in terms of color display, contrast, speed, and power consumption. They are suitable for most uses. But their latest high-end evolution, the famous OLED screens, do even better everywhere, especially in color reproduction and contrast. They are perfect for video, photo processing, or graphic design.
You are up to date on the size and the panel’s technology. But to know which laptop screen to choose, you must consider the screen’s resolution or the number of pixels per inch (PPI; 1 inch = 2.54 cm). This value also significantly contributes to the image quality because the more pixels there are, the better the rendering.
The most common resolution values start at approx. 60 dpi and can go up very quickly depending on the size and Definition of the screen. For its part, the Definition of the screen is the number of pixels in width X the number of pixels in height. But contrary to the resolution, which is always expressed for 1 inch, the Definition alone only means something if it is associated with the screen size.
We, therefore, understand that a definition of 1280 x 720 pixels, for example, on a small 13-inch screen, will always be better than on a larger 17-inch screen (where the pixels will be further apart and the image less sharp). If the resolution is not specified, it is, therefore, necessary to favor the greatest possible Definition to ensure the best image quality. See here an online tool to calculate the resolution from the Definition and the size of the screen: https://www.sven.de/dpi/.
We are talking about speed here. These criteria are essential if you are planning your PC for gaming (gamer) or any application that manages moving images (video editing, film). The refresh rate corresponds to the number of images a screen can display in 1 second. It is expressed in Hz (hertz). The higher this rate, the clearer and more precise the image will be in action sequences.
On a standard laptop PC, the refresh rate is generally 60 Hz, but on a top-of-the-range intended for gaming, it can go up to 144 Hz, or even 240 Hz and more!Response time is the time taken for a pixel to change color or shade. It is expressed in ms (millisecond). The lower this response time, the better the rendering of the movement. Gamers will favor a time of 1 to 3 ms, while this response time will matter less for professional office use.
Choosing your laptop screen must hold your full attention. And to do this, you must determine as clearly as possible the use you will have of it and what you will ask for it most often.
