Comparison MSI Optix G2412 23.8 " black vs MSI Optix G274QPF-QD 27 " 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 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.

Modern monitors can use displays with both glossy and matte screen surfaces. A matte surface is in some cases more preferable due to the fact that on a glossy screen, when exposed to bright light, noticeable glare appears, sometimes interfering with viewing. On the other hand, glossy screens offer better picture quality, higher brightness, and richer colours.
Due to the development of technology, monitors with a special anti-glare coating have appeared on the market, which, while maintaining all the advantages of a glossy screen, creates significantly less visible glare in bright ambient light.

The native resolution of the monitor. Ideally, the resolution of the video signal should be the same, then the quality of the image on the screen will be maximum.

In general, the higher the resolution, the higher the detail and the more advanced the screen is, but the more expensive it will cost (ceteris paribus) and the more power the graphics card will need to work properly at that resolution. As for specific values, they are quite diverse in modern monitors, but all resolutions can be divided into several general categories:

— HD (720). Screens suitable for HD video with a resolution of 1280x720. Note that this category also includes models with a resolution of 1024x768 — this figure is somewhat less than necessary to display HD in its original size, but the quality of the HD picture on such a screen still turns out to be quite high. The most popular option among HD monitors is 1366x768, there are also models 1280x768, 1280x800 and non-widescreen (5:3) 1280x1024.

— Full HD (1080). Full HD monitors. The classic, most popular version of this resolution is 1920x1080 ( 16:9 format), however, there are other options among monitors, including such specific ones as ultra-widescreen (32:9) 3840x1080, as well as 1600x1200 (a 1920x1080 frame “does not fit into it”) ” in width, but this resolution is still commonly r...eferred to as Full HD). To date, Full HD is a good compromise between image quality, screen cost and graphics card requirements. As a result, it is this format that is most popular among modern monitors.

— Quad HD. A kind of intermediate option between the popular Full HD and advanced demanding Ultra HD 4K. It covers resolutions from 1920x1440 to 3200x2400, although most modern Quad HD monitors fit into a narrower range — from 2560x1440 to 3840x1600. Such a screen can be a good option for those who “Full HD is not enough, but 4K is a lot.”

— Ultra HD (4K). This standard assumes a horizontal frame size of approximately 4000 pixels, but specific resolutions may vary. Popular options found in monitors include 3840x2160, 4096x2160, and 4096x2304. Overall, UHD 4K gives you 4 times more pixels on screen than Full HD; such resolutions are typical for high-end monitors and are most often combined with a large diagonal — from 27 "(although there are exceptions).

— Ultra HD (5K). An even more advanced standard than UHD 4K, which assumes a horizontal frame size of about 5000 pixels — for example, 5120x2160. It is used extremely rarely, mainly in top professional screens.

— 8K. Further, after 5K, the development of HD standards, which provides for a frame with a horizontal size of about 8000 — for example, one of the 8K resolution options in monitors is 7680x4320. Allows you to get extremely clear and detailed images, but such high-resolution monitors are very expensive, and it is not so easy to find a signal source in such a resolution. Therefore, only single models of 8K monitors are currently on the market.

The size of one dot (pixel) on a monitor screen. This parameter is related to the maximum resolution of the monitor and its diagonal size — the higher the resolution, the smaller the pixel size (with the same diagonal) and vice versa, the larger the diagonal, the larger the size of one pixel (with the same resolution). The smaller the size of one pixel, the clearer the image will be displayed by the monitor, the less grainy it will be noticeable, which is especially important on large monitors. On the other hand, a small pixel size creates discomfort when working with fine details and text — this mainly applies to monitors with a small diagonal.

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 parameter expresses how long an object moving in the frame is displayed on the screen until it completely disappears. The lower this indicator, the more realistic dynamic scenes look on the monitor. The reaction of the matrix to movements clearly shows the time of existence of the trail from the changing picture. The MPRT parameter is more dependent on the refresh rate of the monitor screen than on the pixel response time. To reduce its value, the Motion Blur Reduction (MBR) function is often used, which briefly turns off the backlight at the end of the time of dynamic frames in order to increase the clarity of dynamic scenes.

The maximum brightness provided by the monitor screen.

Choosing a monitor with high brightness is especially important if the device is going to be used in bright ambient light — for example, if the workplace is exposed to sunlight. A dim image can be "dampened" by such lighting, making work uncomfortable. In other conditions, the high brightness of the screen is very tiring for the eyes.

Most modern monitors give out about 200 – 400 cd / m2 — this is usually quite enough even in the sun. However, there are also higher values: for example, in LCD panels (see "Type") the brightness can reach several thousand cd/m2. This is necessary taking into account the specifics of such devices — the image must be clearly visible from a long distance.

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. .
