Intel Evo platform
A comprehensive laptop branding programme aimed at improving the consumer qualities of portable computers. Its participants fully reveal the capabilities of the hardware platform based on Intel Tiger Lake processors. Laptops with the Intel EVO nameplate must meet a number of stringent requirements: a high-quality calibrated touchscreen display, 11th Gen Intel Core i5/i7 processors with Iris Xe graphics, at least 256 GB NVMe SSD, at least 8 channels of dual-channel RAM GB, support Thunderbolt 4, Bluetooth 5 and Wi-Fi 6, wake up instantly (in 1 second). Also
, branded Intel EVO systems are required to provide from 9 hours of battery life at the end of a full charge and at least 4 hours of battery life after a half-hour charge procedure under daily load conditions. And this is not the whole list of specifications that laptops must meet in order to receive the coveted Intel EVO badge.
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.
Refresh rate
The frame rate supported by the laptop screen. In fact, in this case we are talking about the maximum frequency; the actual frame rate may be lower than this value, depending on the content being displayed — but not higher.
Theoretically, the higher the frame rate, the smoother the movement on the screen will look, the less moving objects will be blurred. In fact, the situation is such that even in relatively modest modern laptops,
60 Hz matrices are installed — in general, this is quite enough for the human eye, since a further increase in speed (
90 Hz and higher) does not significantly improve the visible “picture”. However, in high-end gaming and multimedia models designed for demanding users, higher values —
120 Hz,
144 Hz,
165 Hz and even
higher, namely
240 Hz and
300 Hz.
Colour gamut (sRGB)
The colour gamut of the laptop matrix according to the Rec.709 colour model or according to sRGB.
Colour gamut describes the range of colours that can be displayed on the screen. It is indicated as a percentage, but not relative to the entire variety of visible colours, but relative to the conditional colour space (colour model). This is due to the fact that no modern screen is able to display all the colours visible to humans. However, the larger the colour gamut, the wider the screen's capabilities, the better its colour reproduction.
Specifically, sRGB and Rec.709 are the most popular of today's colour models; they have the same range and differ only in the scope (sRGB is used in computers, Rec. 709 is used in HDTV). Therefore, the closer
the colour gamut is to 100%, the more accurately the colours on the screen will match the colours that were originally intended by the creator of the film, game, etc. At the same time, note that such accuracy is not particularly needed in everyday use — it critical only for professional work with colour; and even in such cases, it is more convenient to buy a separate monitor with a wide colour gamut for a laptop, rather than looking for a laptop with a high-quality (and, accordingly, expensive) matrix.
Colour gamut (Adobe RGB)
The colour gamut of the laptop matrix according to the Adobe RGB colour model.
Colour gamut describes the range of colours that can be displayed on the screen. It is indicated as a percentage, but not relative to the entire variety of visible colours, but relative to the conditional colour space (colour model). This is due to the fact that no modern screen is able to display all the colours visible to humans. However, the larger the colour gamut, the wider the screen's capabilities, the better its colour reproduction.
The Adobe RGB colour model was originally developed for print applications; the range of colours covered by it corresponds to the capabilities of professional printing equipment. Therefore, theoretically, the extensive coverage of this model will be useful to those involved in the design and layout of high-end printed products. However most laptop screens have very limited Adobe RGB values, rarely exceeding 74%; however, you can also find high-end models where this figure
approaches 100%. Of course, the cost of such laptops will also be appropriate; therefore, it makes sense to pay attention to them, first of all, when the ability to work with colour “on the go” is of key importance. If this is to be done in one place, it may be more justified to buy a separate monitor with a wide colour gamut (especially since a monitor with such characteristics is easier to find than a laptop).
TÜV Rheinland certificate
Laptop display certification for safe blue light emission levels and panel flicker rates.
The presence of a TÜV Rheinland certificate confirms that the screen is comfortable for the eyes.
TÜV Rheinland is a large international concern headquartered in Cologne, Germany, providing a wide range of audit services. The company's specialists have developed and approved a number of tests for the compliance of the screens of mobile devices, monitors and TVs with the required level of eye protection from the harmful effects of display radiation on the user's vision on the other side of the screen. The authoritative opinion of TÜV Rheinland is respected in the tech community. Certificates from this body are issued to successfully tested electronics for the implementation of blue light filtering and screen flicker suppression technologies.
HDR
HDR technology format supported by the laptop.
This technology is designed to expand the range of brightness reproduced by the laptop screen; Simply put, an HDR screen will display brighter whites and darker blacks than a regular matrix. In fact, this can significantly improve image quality. First, the expansion of the dynamic range contributes to the brightness and fidelity of colours on the screen; secondly, the visibility of individual details in very bright or very dark areas of the frame is preserved (whereas on a normal screen such details often “sink” in solid white or black).
Note that in order to fully use this function, you need not only
a laptop with HDR, but also the corresponding content (video files recorded in HDR, games where this technology is implemented, etc.). In addition, the laptop must support the HDR format used by the content being played. Nowadays, you can find such options:
— HDR10. Historically the first of the consumer HDR formats, less advanced than those described below, but extremely widespread. In particular, HDR10 is supported by almost all streaming services that provide HDR content at all, and it is also common for Blu-ray discs. Allows you to work with a colour depth of 10 bits (hence the name). At the same time, devices of this format are also compatible with content in HDR10 +, although its quality will be limited by the capabilities of the original HDR10.
...— HDR10+. An improved version of HDR10. With the same colour depth (10 bits), it uses the so-called dynamic metadata, which allows transmitting information about the colour depth not only for groups of several frames, but also for individual frames. This results in an additional improvement in colour reproduction.
Dolby Vision. An advanced standard used particularly in professional cinematography. Allows you to achieve a colour depth of 12 bits, uses the dynamic metadata described above, and also makes it possible to transmit two image options at once in one video stream — HDR and normal (SDR). At the same time, Dolby Vision is based on the same technology as HDR10, so in laptops it is almost guaranteed to be combined with at least HDR10, and even with HDR10 +.Gorilla Glass
The presence
of Gorilla Glass in the design of the laptop display; the specific version of such material may also be specified in this paragraph.
The Gorilla Glass brand produces special tempered glass, which, despite its small thickness, has excellent characteristics of strength, transparency and scratch resistance. In general, this coating is more advanced than more traditional materials used in laptops (such as matte or glossy plastic), but it is also more expensive; therefore, it is found mainly in fairly expensive models with high-quality displays, including touch ones.
As for the different versions of this coating, they differ both in protective properties and in a number of other characteristics. Here are the main options relevant today:
- Gorilla Glass v3. The oldest current version was released in 2013. However, even this coating is noticeably superior to traditional glass (not to mention plastic) in terms of transparency and scratch resistance.
- Gorilla Glass NBT. The same age as the v3 version described above, released in 2013. The main feature is that the NBT coating was originally developed specifically for laptops with touch screens (while v3 was created mainly with smartphones in mind). The manufacturer claims, in particular, 8 to 10 times greater scratch resistance than conventional glass (including retention of strength when scratches occur and reduced visibility of such damage)
..., as well as impact resistance and low sensitivity to fingerprints. However, there is no data on the fundamental differences between such glass and regular v3.
- Gorilla Glass v4. Version released in 2014. A key feature is that the design of this coating focused on impact resistance (whereas previous generations focused primarily on scratch resistance). As a result, the glass turned out to be twice as strong as in version 3, despite the fact that its thickness was only 0.4 mm.
- Gorilla Glass v5. An improvement to the "gorilla" released in 2016 that aims to further improve impact resistance. According to the developers, the v5 glass turned out to be 1.8 times stronger than its predecessor; it remained intact in 80% of drops from a height of 1.6 m “face down” onto a rough surface.
- Gorilla Glass v6. Version introduced in 2018. This coating claims to have a 2-fold increase in strength compared to its predecessors, as well as the ability to withstand multiple drops on a hard surface (in tests, v6 glass successfully withstood 15 drops from a height of 1 m).
- Gorilla Glass v7. Gorilla Glass v7 provides reliable protection for your laptop screen from impacts, drops and scratches. This generation promises an increase in drop resistance by approximately 150%, and scratch resistance by as much as 200%.
- Gorilla Glass DX. A version originally created for smart watches and other compact gadgets; It is extremely rare among laptops - in some “2-in-1” models. It was introduced in 2018 along with Gorilla Glass v6. The key improvements in this version include, in particular, increased anti-reflective properties and an increase in the contrast level of the visible image by 50%; the latter, among other things, makes it possible to reduce the actual brightness and, accordingly, the power consumption of screens without compromising image quality.Model
The specific model of the processor installed in the laptop, or rather, the processor index within its series (see above). Knowing the full name of the processor (series and model), you can find detailed information on it (up to practical reviews) and clarify its capabilities.
