Screen size
Diagonal size of laptop display.
The larger the screen, the more convenient the laptop for watching high-definition movies, modern games, working with large-format graphic materials, etc. Large screens are especially important for multimedia and gaming models. On the other hand, the diagonal of the display directly affects the size and cost of the entire device. So if portability is key, it makes sense to pay attention to relatively small solutions; especially since most modern laptops have video outputs like HDMI or DisplayPort and allow connection of large-format external monitors.
In light of all this, the actual maximum for laptops these days is
17"(17.3"); however
larger devices (18") reappeared at the beginning of 2023. The standard option for general purpose laptops is
15"(15.6"), less often
16", a diagonal of
13"(13.3") or
14" is considered small by the standards of such And smaller screens can be found mainly in specific compact varieties of laptops — ultrabooks, 2 in 1, transformers, netbooks; among such devices there are solutions for
12 ",
11" and even
10" or less.
Screen resolution
The resolution of the screen installed in the laptop — that is, the size of the screen in pixels horizontally and vertically.
Higher resolution, on the one hand, gives a sharper, more detailed image; on the other hand, it increases the cost of the laptop. The latter is connected not only with the cost of the displays themselves, but also with the fact that in order to work effectively at high resolutions, you need the appropriate filling (primarily a graphics card). This is especially true in games; so if you are looking for a laptop with a high-resolution screen that can effectively "run" modern games — you should pay attention not only to the characteristics of the display, but also to other data (the type and parameters of the graphics card, test results, the ability to work with certain games — see everything below). On the other hand, if the device is planned to be used for simple tasks such as working with documents, surfing the Internet and watching videos, you can not pay much attention to the “hardware” parameters: anyway, they are selected so that the laptop is guaranteed to be able to cope with such tasks on full resolution of the "native" screen.
As for specific numbers, the resolution options that are relevant today can be divided into 4 groups:
HD (720),
Full HD (1080),
Quad HD and
UltraHD 4K. H
...ere is a more detailed description of them:
— HD (720). This category includes all displays that have a vertical size of less than 1080 pixels. The most popular HD resolution in modern laptops is 1366x768; in devices larger than 15.6 ", 1600x900 is also often found. Other values quite exotic and are rarely used. In general, screens of this standard are now typical mainly for entry-level laptops.
— Full HD (1080). Initially, the Full HD standard provides a frame size of 1920x1080, and it is this resolution that is most often used in laptop screens from this category. However, in addition to this, other resolution options are also included in this format, where the vertical size is at least 1080 pixels, but does not reach 1440 pixels. Examples include 1920x1200 and 2560x1080. In general, Full HD displays provide a good balance between cost, image quality and laptop hardware requirements. Because of this, nowadays they are extremely widespread; matrices of this standard can be found even in low-cost devices, although they are mainly used in more advanced technology.
— Quad HD. A transitional option between the popular Full HD 1080 (see above) and the high-end and expensive UltraHD 4K. The vertical size of such screens starts from 1440 pixels and can reach 2000 pixels. Note that QuadHD resolutions are especially popular in Apple laptops; most often, such devices have 2560x1600 screens, although there are other options.
— Ultra HD 4K. The most advanced standard used in modern laptops. The vertical size of such screens is at least 2160 dots (up to 2400 in some configurations); the classic resolution of a modern UltraHD matrix is 3840x2160, but there are other values. Anyway, a 4K display allows for high image quality, however, it costs accordingly — including due to the corresponding requirements for a graphics adapter; in addition, to work with high resolutions, it can be more convenient to connect an external monitor to the laptop. Thus, such screens are used relatively rarely, and mainly among premium laptops.Brightness
The maximum brightness that a laptop screen can provide.
The brighter the ambient light, the brighter the laptop screen should be, otherwise the image on it may be difficult to read. And vice versa: in dim ambient light, high brightness is unnecessary — it greatly burdens the eyes (however, in this case, modern laptops provide brightness control). Thus, the higher this indicator, the more versatile the screen is, the wider the range of conditions in which it can be effectively used. The downside of these benefits is an increase in price and energy consumption.
As for specific values, many modern laptops have a brightness of
250 – 300 cd / m2 and even
lower. This is quite enough for working under artificial lighting of medium intensity, but in bright natural light, visibility may already be a problem. For use in sunny weather (especially outdoors), it is desirable to have a brightness margin of at least
300 – 350 cd / m2. And in the most advanced models, this parameter can be
350 – 400 cd / m2 and even
more.
Contrast
The contrast of the screen installed in the laptop.
Contrast is the largest difference in brightness between the lightest white and darkest black that can be achieved on a single screen. It is written as a fraction, for example, 560:1; while the larger the first number, the higher the contrast, the more advanced the screen is and the better the image quality can be achieved on it. This is especially noticeable with large differences in brightness within a single frame: with low contrast, individual details located in the darkest or brightest parts of the picture may be lost, increasing the contrast allows you to eliminate this phenomenon to a certain extent. The flip side of these benefits is an increase in cost.
Separately, we emphasize that in this case only static contrast is indicated — the difference provided within one frame in normal operation, at constant brightness and without the use of special technologies. For advertising purposes, some manufacturers may also provide data on the so-called dynamic contrast — it can be measured in very impressive numbers (seven-digit or more). However, you should focus primarily on static contrast — this is the basic characteristic of any display.
As for specific values, even in the most advanced screens, this indicator does not exceed 2000: 1. But in general, modern laptops have a rather low contrast ratio — it is assumed that for tasks that require more advanced image characteristics, it is more...reasonable to use an external screen (monitor or TV).
Passmark CPU Mark
The result shown by the laptop processor in the Passmark CPU Mark test.
Passmark CPU Mark is a comprehensive test that is more detailed and reliable than the popular 3DMark06 (see above). It checks not only the gaming capabilities of the CPU, but also its performance in other modes, based on which it displays the overall score; this score can be used to fairly reliably evaluate the processor as a whole (the more points, the higher the performance).
Max. RAM
The maximum amount of RAM that can be installed on a laptop. It depends, in particular, on the type of memory modules used, as well as on the number of slots for them. Paying attention to this parameter makes sense, first of all, if the laptop is bought with the expectation of
and the amount of actually installed memory in it is noticeably less than the maximum available. So laptops can be upgraded in RAM to 16 GB,
24 GB a>,
32 GB, 48 GB,
64 GB and even more -
128 GB.

Note that all the above models are discrete. Actually, for a configuration with discrete graphics, it is the model of a separate video adapter that is indicated; if it is supplemented by an integrated module, the name of this module can be clarified by the official characteristics of the processor.
It is also worth mentioning that this paragraph does not give the full name of the model, but only its name within the series (the series itself is given separately - see above). However, knowing the series and model, one can easily find detailed information about the graphics card.Video memory
The amount of native video memory installed in the laptop's graphics card. Only discrete video adapters and their advanced varieties like SLI or Dual Graphics have such memory (see "Video card type").
The more memory, the more powerful the graphics card and the better it can handle complex graphics. Of course, the specific capabilities of the adapter depend on a number of other parameters (primarily the characteristics of the graphics processor); however, the difference in the amount of memory, as a rule, is quite consistent with the difference in the overall level. In terms of specific numbers, solutions with
2 GB are entry-level,
4 GB and
6 GB are intermediate, and
8 GB - to advanced, and
12 GB and
16 GB can be found in top-end gaming laptops and high-end workstations.
GPU TDP
The amount of heat generated by the graphics processing unit (GPU) during normal operation. TDP is expressed in watts. It allows you to evaluate the thermal characteristics of a laptop and determine its potential for working with high graphics loads. The higher the GPU TDP value, the more power the GPU consumes, which may require a more efficient cooling system to avoid overheating and ensure stable operation of the device. Laptops with higher GPU heat dissipation are better suited for gamers or graphics and video production professionals.
