Comparison MSI Optix G2412 23.8 " black vs MSI Optix G24C4 24 " black

Diagonal size of the monitor matrix, in inches.

This parameter is one of the most important for any screen — it determines the total size of its working area. In general, it is believed that larger monitors are more comfortable: a large screen allows you to see a large fragment of text, images, etc. without having to scroll the "picture". On the other hand, the diagonal directly affects the dimensions, weight and cost of the monitor. In addition, it is worth remembering that screens with the same diagonal can have different aspect ratios and different specializations: for example, widescreen models are convenient for playing games and watching movies, while classic 4:3 or 5:4 solutions are preferable for working with documents. Now there are monitors of different diagonals on the market, among them the most popular are: 19–20", 22", 23 – 24", 25 – 26", 27 – 28", 29 – 30", 32", 34" and more.

The presence of a curved screen in the monitor design.

Such a screen has the left and right edges curved forward - it is believed that this shape significantly improves perception compared to a flat surface. At the same time, it makes sense to provide this feature only on fairly large diagonals - at least 30"; therefore, it is typical mainly for high-end models. It is also worth noting that in order to take advantage of all the advantages of a curved screen, you need to look at it from a certain point - at the optimal distance, strictly in the center; however, for computer monitors this is usually not a problem.

The main parameter of a curved screen is the radius of curvature. It is indicated in millimeters along the radius of a circle, the bend of which corresponds to the bend of the monitor: for example, the designation 1800R indicates a radius of 1.8 m.

The smaller the number in this designation, the more curved the screen (all other things being equal). At the same time, some manufacturers claim that the ideal curvature value is 1000R: supposedly, it is with this curvature of the screen that the image on it turns out to be as close as possible to a person’s natural field of vision, and the closer the curvature of the monitor is to 1000R, the better the viewing experience. However, in practice a lot depends on personal preference; and when viewed from a long distance (exceeding the radius of curvature by one a...nd a half times or more), all the advantages of a curved screen are lost.

The technology by which the monitor matrix is made.

— TN+film. The oldest and most common technology for manufacturing matrices. The original TN (Twisted Nematic) monitors have a low response time and low cost, but the image quality is average. So, the colour quality is not high, and the perfect black colour cannot be reproduced at all. In addition, the original TN technology provides relatively small viewing angles. To correct this situation, a special film is applied to the surface of the matrix. These matrices received the name "TN + film". Monitors with such a matrix are widespread and inexpensive. They are well suited for undemanding users both at home and in the office, and gamers will appreciate the fast response time.

— *VA(Vertical Alignment, options: MVA, PVA, Super MVA, Super PVA). A kind of transitional option between expensive and high-quality IPS and low-cost TN. Provide sufficiently high-quality colour reproduction, including black colour, viewing angles can reach 178°. The main disadvantage of VA matrices is the significant response time (especially for MVA monitors), due to which such monitors are relatively poorly suited for watching videos and dynamic games. This shortcoming is gradually being eliminated, and the latest models of VA monitors are approaching TN + film in respo...nse time.

— IPS. Initially, IPS technology was created for high-end monitors (in particular, "designer"), the key parameters for which were the quality of colour reproduction and a wide colour gamut. With all these advantages, the original IPS matrices also had a number of serious drawbacks — first of all, low response speed and impressive cost. Thus, many modifications of the IPS technology have been developed, designed to compensate for these shortcomings to one degree or another.

— OLED. Monitors with screens using organic light emitting diodes — OLED. Such LEDs can be used both to illuminate a traditional matrix, and as elements from which a screen is built. In the first case, the advantages of OLED over traditional LED backlighting are compactness, extremely low power consumption, backlight uniformity, as well as excellent brightness and contrast ratios. And in matrices, consisting entirely of OLED, these advantages are even more pronounced. The main disadvantages of OLED monitors are the high price (which, however, is constantly decreasing as the technology develops and improves), as well as the susceptibility of organic pixels to burn-in when broadcasting static images for a long time or pictures with static elements (toolbar, clock, etc.).

— QLED. Monitors built using quantum dot technology (QLED). This technology can be used in matrices of various types. It involves replacing a set of several colour filters used in classic matrices with a special thin-film coating based on nanoparticles, and traditional white LEDs with blue ones. This allows you to achieve higher brightness, colour saturation and colour quality at the same time as reducing the thickness and reducing power consumption. In addition, QLED is well suited for creating curved screens. The flip side of these benefits is the high price.

— QD-OLED. A kind of hybrid version of matrices that combine “quantum dots” (Quantum Dot) and organic light-emitting diodes (OLED) in one bottle. The technology takes the best from QLED and OLED: it is based on blue LEDs, self-luminous pixels (instead of external backlighting) and “quantum dots”, which play the role of color filters, but at the same time practically do not attenuate the light (unlike traditional filters) . Thanks to the use of a number of advanced solutions, the creators managed to achieve very impressive characteristics, significantly superior to many other OLED matrices. Among them are high peak brightness from 1000 nits (cd/m²), excellent contrast and black depth, as well as an expanded color gamut (over 120% of the DCI P3 gamut). Such matrices are found mainly in expensive advanced monitors with a large screen diagonal.

— AHVA. A type of matrix created by AU Optronics (a joint venture between Acer and BenQ) as a solution similar to modern IPS. Among the key advantages of this option over analogues is the almost complete absence of colour distortions at all viewing angles.

– PLS (Plane to Line Switching). This type of matrix was developed by Samsung engineers. It is based on the familiar IPS technology. According to some parameters, namely: the brightness and contrast of PLS exceeds IPS by 10%. The main goal of creating a new type of screens was to reduce the cost of the matrix, according to the developer, the production cost was reduced by 15%, which will positively affect the final price of monitors in comparison with IPS counterparts.

— IGZO. Technology introduced by Sharp in 2012. The key difference between IGZO and classic LCD matrices is that for the active layer (responsible for creating the image) it uses not amorphous silicon, but a semiconductor material based on indium gallium oxide and zinc oxide. This makes it possible to create screens with extremely fast response times and high pixel densities, and the technology is considered well suited for ultra-high resolution screens. With all this, the colour rendering characteristics allow the use of IGZO monitors even in the professional field, and the power consumption is very low. The main disadvantage of this option is the high cost.

— UV2A. An LCD display technology developed by Sharp and introduced in 2009. One of the key features of UV2A matrices is that they are based on liquid crystals that are sensitive to ultraviolet light. And it is UV radiation that is used as a control signal — it ensures that the crystals turn in the right direction to form an image. The technical features of such systems are such that the position of individual crystals can be controlled with extremely high accuracy — up to several picometers (with the size of the crystals themselves about 2 nm). According to the manufacturer, this provides two key benefits: no backlight "leakage" and improved light transmission with "open" crystals. The first allows you to achieve very deep and rich blacks, the second provides excellent brightness with low power consumption, and together these two features make it possible to create screens with a very high static contrast ratio — up to 5000: 1. At the same time, we note that the actual contrast characteristics in UV2A monitors can be noticeably more modest — it all depends on the features of a particular matrix and the characteristics that the manufacturer was able or considered necessary to provide.

— Mini LED IPS. A variation on the theme of the familiar IPS-matrix, which is illuminated by an array of reduced LEDs. The small caliber of individual light sources (of the order of 100-200 microns) makes it possible to form a much larger number of zones of controlled local dimming of the screen. Together, this delivers improved brightness, contrast, colour saturation, and black depth, and raises the bar for High Dynamic Range (HDR) technology.

— Mini LED VA. A variety of VA-matrices with a Mini LED backlight system. It consists of many tiny LEDs, which, due to their number, form many times more local screen dimming zones than standard canvases. As a result, Mini LED VA panels boast improved colour reproduction, impressive black depth, and multiple performance improvements in HDR content.

— Mini LED QLED. Behind the plane of the QLED panel in monitors with a Mini LED backlight system are thousands of miniature LEDs no larger than 200 microns in size, which divide the screen into a great many zones with controlled local dimming. They are individually dimmable, allowing full display of HDR content with bright light and deepest black levels.

The time each individual pixel on the monitor takes to switch from one state to another. The lower the response time, the faster the matrix responds to the control signal, resulting in less delay and better image quality in dynamic scenes.

Note that in this case, the gray-to-gray method is used (the time it takes to switch from 10% gray to 90% gray). Pay attention to this parameter if the monitor is specifically purchased for fast-paced games, movie watching, or other applications involving quick screen movements. However, there’s no need to chase the fastest models. It’s not often possible to discern the difference between 1 ms and 5 ms. For most scenarios, monitors with a 4 ms response time will suffice. In any case, it’s best to rely on live impressions for a true comparison.

The maximum frame rate supported by the monitor at the recommended (maximum) resolution.

The higher the frame rate, the smoother the movement on the screen will look, the less noticeable jerks and blurring will be on it. Of course, the actual image quality also depends on the video signal, but for normal viewing of video at a high frame rate, the monitor must also support it.

When choosing this option, keep in mind that at lower resolutions than the maximum, the supported frame rate may be higher. For example, a model with a 1920x1080 matrix and a claimed frame rate of 60 Hz at a reduced resolution can give 75 Hz; but the 75Hz frame rate is only listed in the specs if it is supported at the monitor's native (maximum) resolution.

Also note that a high frame rate is especially important for gaming models (see "Type"). In most of them, this figure is 120 Hz and higher; monitors with a frequency of 144 Hz are considered the best option in terms of price and quality, however, there are also higher values — 165 Hz and 240 Hz. And monitors at 100 Hz can be both inexpensive gaming models and advanced home ones.

You can evaluate all the frame rates at which this monitor is capable of operating by the ver...tical frequency claimed in the specifications (see below).

Static contrast provided by the monitor screen.

This value describes the difference between the brightest whites and darkest blacks that the screen is capable of producing. In this case, unlike dynamic contrast (see below), the difference is indicated on the condition that the brightness of the screen backlight remains unchanged. In other words, this is the contrast that is guaranteed to be achievable within one frame. Static contrast is inevitably lower than dynamic. However, it is she who describes the basic capabilities of the screen.

The minimum static contrast ratio for tolerable image quality is considered to be 250:1, but even the most modest modern monitors give out about 400:1 (and a value of 1000:1 is not the highest class), and in high-end models this figure can reach 2000:1 and even more. .

Monitor colour gamut Rec. 709 or sRGB.

Any colour gamut is indicated as a percentage, however, 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 monitor's capabilities, the better its colour reproduction.

Nowadays, sRGB is actually the standard color model adopted for computer technology; This is what is used in the development and production of most video cards. For television, the Rec. standard, similar in parameters, is used. 709. In terms of the range of colors, these models are identical, and the percentage of coverage for them is the same. In the most advanced monitors it can reach or even exceed 100%; These are the values that are considered necessary for high-end screens, incl. professional.

Monitor colour gamut based on the Adobe RGB colour model.

Any colour gamut is indicated as a percentage, however, 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 monitor's capabilities, the better its colour reproduction.

Specifically, the Adobe RGB colour model was originally developed for use in printing; the range of colours covered by it corresponds to the capabilities of professional printing equipment. Accordingly, support for this model and its extensive colour gamut are important, first of all, if the monitor is used in the design and layout of high-quality printed products. In the most advanced screens, this figure can be 99% or even more. At the same time, we note that Adobe RGB is wider than the popular sRGB, and the percentage figures for this model are smaller: for example, 99% in RGB often gives only about 87% in Adobe RGB.

Colour gamut of the monitor according to the DCI P3 colour model.

Any colour gamut is indicated as a percentage, however, 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 monitor's capabilities, the better its colour reproduction.

DCI P3 is a professional colour model used primarily in digital cinemas. It is noticeably more extensive than the standard sRGB, which gives better and more accurate colours. Accordingly, the percentage values are smaller — for example, 115% of sRGB coverage corresponds to approximately 90% of DCI P3 coverage; in the most advanced modern monitors, coverage according to this standard is 98 – 100%. At the same time, DCI-P3 support is not cheap, and therefore it is found mainly in high-end monitors for professional and gaming purposes.
