Comparison LG UltraGear 45GR95QE 44.5 " vs Samsung Odyssey OLED G85SB 34 34 " silver

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.

Operating system that controls the smart functionality of the monitor, which combines the capabilities of traditional models and smart TVs.

— Tizen. Samsung's proprietary development based on the open source Linux kernel. The lion's share of smart TVs from the South Korean electronics brand runs Tizen OS, and this platform is also found in the brand's smart monitors. The operating system allows you to install and run applications, provides access to online services for watching streaming videos, listening to music and consuming other entertainment content, can be used as central hub for smart home ecosystems, and has built-in voice assistants (including the proprietary Bixby).

- webOS. Smart platform from LG, which is found in the brand’s “smart” TVs and monitors. It boasts flexible menu interface customization, high operating speed and support for installing third-party applications from the company store. webOS provides access to content streaming services, streaming platforms and popular video hosting sites. The functionality of the “OS” is in all its glory when using the Magic Remote air control.

— Android. Full-fledged software firmware based on Android OS, adapted to work on large screens. In addition to the common features of all Android devices (such as the ability to install additional applications, including even games), it has number of special features: an optimized interface, integration with smartphones (including...the ability to use them as remote control), voice search, etc. Of course , in order to operate multifunctional OS, the monitor must have dedicated processor, graphics subsystem and memory, and the presence of such hardware resources is reflected in the total cost of the device.

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 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 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).

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. .

Dynamic contrast provided by the monitor screen.

Dynamic contrast refers to the difference between the brightest white at maximum backlight intensity and the deepest black at minimum backlight. In this way, this indicator differs from static contrast, which is indicated with a constant backlight level (see above). Dynamic contrast ratio can be expressed in very impressive numbers (in some models — more than 100,000,000: 1). However, in fact, these figures are poorly correlated with what the viewer sees: it is almost impossible to achieve such a difference within one frame. Therefore, dynamic contrast is most often more of an advertising than a practically significant indicator, it is often indicated precisely in order to impress an inexperienced buyer. At the same time, we note that there are "smart" backlight technologies that allow you to change its brightness in certain areas of the screen and achieve a higher contrast in one frame than the claimed static one; these technologies are found mostly in premium monitors.

The colour depth supported by the monitor.

This parameter characterizes the number of shades that the screen can display. And here it is worth recalling that the image in modern monitors is based on 3 basic colours — red, green, blue (RGB scheme). And the number of bits is indicated not for the entire screen, but for each base colour. For example, 6 bits (the minimum colour depth for modern monitors) means that the screen is capable of producing 2 ^ 6, that is, 64 shades of red, green and blue; the total number of shades will be 64 * 64 * 64 = 262,144 (0.26 million). An 8-bit colour depth (256 shades for each base colour) already gives a total of 16.7 million colours; and the most advanced modern monitors support 10-bit colour, allowing you to work with more than a billion shades.

Screens with support for FRC technology are worth a special mention; nowadays, you can find models marked " 6 bit + FRC " and " 8 bit + FRC ". This technology was developed to improve picture quality in situations where the incoming video signal has a greater colour depth than the screen, such as when 10-bit video is fed to an 8-bit matrix. If such a screen supports FRC, the picture on it will be noticeably better than on a regular 8-bit monitor (although somewhat worse than on a full-fledged 10-bit monitor, but “8 bit + FRC” screens are much...cheaper).

High colour depth is important primarily for professional graphics and other tasks that require high colour fidelity. On the other hand, such features significantly affect the cost of the monitor. In addition, it is worth remembering that the quality of colour reproduction depends not only on the colour depth, but also on other parameters — in particular, colour gamut (see below).
