Comparison Lenovo Legion Pro 5 16IRX8 [5 16IRX8 82WK0083US] vs Asus ROG Strix G16 2023 G614JI [G614JI-AS95]

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.

Screen response time to a control signal — in other words, the time between the receipt of such a signal on the matrix and the switching of pixels to a given mode.

Theoretically, the lower the response time, the better the screen handles with dynamic scenes, the higher the frame rate on it can be achieved. At the same time, it is worth noting that almost all modern matrices have sufficient response speed to effectively process the classic frame rate of 60 Hz — and, recall, it is quite enough for most cases. So paying attention to this parameter makes sense, first of all, if you are purchasing an advanced gaming model, the screen of which operates at a frame rate of more than 60 Hz. In other cases, the response time is often not indicated at all.

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.

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 nt 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 nt. And in the most advanced models, this parameter can be 350 – 400 nt and even more.

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).

This feature means that the laptop screen has received the Pantone Validated certification.

Pantone is a professional colour system created by the company of the same name and widely used in design and printing. One of Pantone's basic ideas is that each colour should remain the same at all stages of work — from agreeing on a general idea to printing / releasing the final product; To do this, all shades covered by the system are assigned code names, which are used in the work. In the case of laptops, Pantone certification means that when working with materials and software tools that use a given colour scheme, the colours on the screen will match the actual Pantone hues as closely as possible.

We emphasize that there is no question of perfect correspondence (LCD matrices are not physically capable of adequately displaying some shades); in addition, screens with such certification may have different colour gamuts — both in percentages and in the systems used for designation (sRGB, Adobe RGB, DCI P3 — see above). However, even if the colour is beyond the capabilities of the screen, it will be displayed as accurately as possible. Therefore, for professional tasks associated with intensive use of Pantone, it is worth choosing monitors with official certification; An example of such tasks is the printing of image printing.

VESA DisplayHDR certified, which corresponds to a screen that supports HDR technology.

See above for more details on this technology. And VESA DisplayHDR is an open standard that defines the overall image quality on an HDR screen by a number of parameters — brightness, colour depth, etc. Based on the test results, a screen that meets the required parameters is assigned a certain certificate with a numerical designation. So, the minimum level is DisplayHDR 400, the maximum is DisplayHDR 1400 (although in laptops, as of the end of 2020, there are no screens higher than DisplayHDR 1000). The number in such a designation is indicated by the brightness that the screen must provide: for example, DisplayHDR 400 must produce at least 400 cd / m2. Accordingly, a higher number denotes more extensive display capabilities and more advanced HDR performance.

A separate case is the DisplayHDR True Black certifications. This standard was specifically created for so-called emissive displays such as OLED (see "Matrix type"), which are capable of displaying very deep blacks. The native brightness of such displays is not very high — in particular, the current DisplayHDR 400 True Black and DisplayHDR 500 True Black provide a total screen brightness of only 250 and 300 cd / m2, respectively (against 400 and 500 cd / m2 in the original standards, without the addition " True Black"). However, in terms of black transmission efficiency, such...displays surpass conventional HDR counterparts by orders of magnitude, which gives a noticeable increase in image quality — in particular, the mentioned True Black standards with indexes 400 and 500 win even when compared with conventional DisplayHDR 1000. However, it should be taken into account that that this advantage is most noticeable in relatively dim ambient light.

Laptop screen support for VESA Adaptive-Sync technology.

The feature aims to synchronize the refresh rate of the display with the frame rate of the GPU to reduce latency, minimize artifacts, and eliminate visual tearing in the image. Adaptive-Sync-certified screens should run at refresh rate of 120Hz by default, and the frame rate should be able to drop to 60Hz. The actual response time of such displays should be less than 5 ms.

It is important to note that VESA Adaptive-Sync technology is only available for DisplayPort 1.2a or higher.

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.
