What is the appropriate resolution for a laptop computer?

Recently, many freshmen have encountered a lot of problems when buying laptops. Recently, some netizens asked what resolution is better for laptops. Is the larger the resolution of the laptop screen, the better? Regarding this issue, you can say this There is no standard answer. This depends on your needs and habits. The higher the resolution, the clearer the image quality, but correspondingly, the font size will become smaller, which is not particularly good for some elderly people. Next, let’s give you a detailed introduction to this issue.

It is decided based on the actual usage needs and feelings. Graphic design and programming need to display as many things as possible on the screen. Naturally, high resolution is better, but if there is no need, then high resolution A high-speed screen may not be required.

Before discussing the resolution of notebook LCD screens, we must understand the concept of "dot pitch". In CRT monitors, the pixel pitch (Pixel Pitch) of CRT monitors of the same size will change due to differences in the design of the shadow mask or grating, the type of video card, and the vertical or horizontal scanning frequency, which can be different. In an LCD display, the dot pitch (Dot Pitch) is the distance between the light spots of two liquid crystal particles. The calculation method is the value obtained by dividing the panel size by the resolution. Therefore, when the size and resolution are the same, the LCD The number of pixels on a monitor is fixed. From this we can know that the biggest difference in dot pitch between CRT monitors and LCD monitors is that the former can adjust the dot pitch by adjusting the resolution, while the optimal resolution of a certain size panel of the latter is fixed and cannot be adjusted.

The smaller the dot pitch of the LCD monitor, the finer the picture, but the smaller the characters; conversely, the larger the dot pitch, the larger the font, the clear outline, and the easier it is to see, but the picture will appear rough. . In layman's terms, if you are used to looking at a 12.1-inch widescreen notebook LCD screen, you will obviously feel that the font size has become smaller when you first see a 15.4-inch notebook LCD screen, because the resolution of the notebook LCD screen and its panel Size has a certain relationship, the larger the size, the greater the resolution. Therefore, the choice of point pitch requires a trade-off between text and graphics/video applications. It should not be too large or too small. Generally, it can be considered that the point pitch between 0.27mm and 0.30mm is the most comfortable. ​

Since notebook user groups are more diverse, notebook LCD screens are divided into more types according to market needs. Take the currently very popular widescreen notebooks, which can be divided into WXGA, WXGA+, WSXGA+, and WUXGA specifications. , each specification has its own resolution scheme.

WXGA: The abbreviation of Wide Extended Graphics Array. It is the widescreen version of XGA, using a 16:10 aspect ratio screen size and a maximum resolution of 1280×800. It has only 800 horizontal pixels, so it is usually used on 15-inch and 12.1-inch laptops; WXGA+: the abbreviation of Wide Extended Graphics Array is an extension of WXGA, and the maximum resolution is 1280×854, because the aspect ratio is 15:10. It is not a standard widescreen 16:10, so it is only used in a small number of 15.2-inch laptops; WSXGA+: Abbreviation of Wide Super Extended Graphics Array, the resolution is 1680×1050, mainly used in laptops above 15 inches; WUXGA: Wide Ultra. Abbreviation of Video Graphics Array. The widescreen version of UXGA screen supports 1920×1200 and is very expensive, so it is often used in high-end widescreen laptops or mobile workstations.

Therefore A new problem has arisen: even notebooks of the same size may have different LCD screen resolutions, resulting in different dot pitches of the LCD screens. For example, the recently popular Dell Latitude D630 uses the latest LCD screen. 14.1-inch WXGA+ LCD widthThe screen has replaced the previous WXGA LCD screen, and the resolution has been increased from the original 1280×800 to 1440×900. Although a high-resolution LCD screen allows you to browse more content on the same screen, and you can have a more detailed display effect on the same size screen, it also means that the fonts are smaller than those at 1280×800 resolution, which is not necessarily the case. Applicable to all users, such as some slightly older users with presbyopia.

High-resolution LCD screens cost more than low-resolution LCD screens, but high-resolution notebooks may not be suitable for all types of users. If it is at the same price, whether to choose a high-resolution LCD notebook cannot be judged based on whether it is "cost-effective", but must be based on your personal application needs as the only guide.

There is another misunderstanding here, that is, the resolutions of LCD monitors and CRT monitors are confused. It is believed that the resolution of notebook LCD screens is adjustable. For example, a certain resolution On a 1920×1200 notebook LCD screen, if you feel that the fonts in the 1920×1200 display mode are too small, can adjusting to a resolution of 1680×1050 or 1440×900 solve the problem of small fonts? The actual situation shows that for notebook LCDs, Any change in the screen resolution will affect its display effect. In mild cases, there will be a slight burr phenomenon, and in severe cases, it will cause stretching.

As for how to solve the problem of small fonts on high-resolution LCD screens, here is another solution, which is to change the font options in the WINDOWS display properties: right-click the area without icons on the desktop Click Properties or click Control Panel --> Appearance Themes --> Display Font Size. But in this way, the advantages of high-resolution LCD screens are eliminated.

The main benefit of a high-resolution screen is that it provides a natural field of view and more work areas, such as panoramic animations, precise financial statements, cross-page complex file operations, etc. The biggest advantage is that it can increase the user's working area. , can display more content at the same time, allowing users to perform multiple tasks at the same time without frequent switching. Faced with such setbacks, it is better to choose a notebook with suitable LCD screen size and resolution in one step.

Summary: What is the appropriate laptop screen resolution? This depends on your own needs. The editor has a friend who is a programmer. The resolution of his laptop is very large, and the fonts are as small as a grain of rice. But let me give you some suggestions. First, friends who need a wide field of view should choose large-size notebooks as much as possible and some notebooks with high resolutions. Second, for those who need large fonts, just choose a portable notebook. Of course, this can be adjusted.
