Comparison Samsung Odyssey OLED G60SD 27 27 " silver vs Samsung Odyssey OLED G80SD 32 32 " 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 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 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).

Bluetooth technology (any version) is used for direct wireless communication between various devices. The way it is implemented in monitors may vary, depending on the functionality of the specific model (and Bluetooth version). Thus, it may be possible to broadcast sound to wireless headphones or speakers. In addition, other use cases are provided: connecting keyboards, mice, game controllers, direct file exchange with a laptop, remote control from a smartphone or other gadget, etc. These details should be clarified separately. As for specific versions, in many models these details are not specified at all - for use for the originally intended purpose, “just Bluetooth” is enough.

The monitor has a built-in Wi-Fi module. This paragraph may also specify the supported version of this technology. Nowadays, Wi-Fi can be used both for wireless access to the Internet and local networks, and for direct connection with other devices (for example, broadcasting video from a smartphone/tablet). The specific use of a wireless connection may vary, depending on the functionality of the monitor: providing Internet access, receiving or transmitting video via Wi-Di or Miracast, as well as using a mobile gadget as a remote control. Built-in Wi-Fi can often be found on board models that support smart features.

— Mini-Jack input (3.5 mm). Audio input with standard 3.5mm mini-jack. Usually, it looks like a socket into which a mini-jack plug is connected from a signal source. The signal itself from such an input can be fed either to the monitor's built-in speakers or to the audio output (see below for both).

— Mini-Jack output (3.5 mm). Analogue audio output using a standard 3.5mm mini-jack. Usually it is universal, it can be used both for connecting headphones and as a line output for computer speakers or other active acoustics. The presence of an audio jack on the monitor is convenient because such a port is usually closer to the user than the audio card outputs, and connecting headphones or speakers directly to the monitor is easier than pulling a wire to the system unit.

-LAN. Standard connector for wired connection to computer networks. The presence of such an input in most cases turns the monitor into a network device: any network user with the appropriate access rights can display an image on it. Another use case for LAN is a direct connection to another device. For example, in this way you can connect a laptop with a LAN output without disconnecting the monitor from the PC (to which it can be connected, for example, via the DVI interface). And some especially advanced models have embedded software tools that allow using t...he local network to view the contents of devices connected to this network, and even use some web services directly from the monitor, without using a computer as such.

— Composite. One of the simplest and most common analogue audio/video inputs. Like component, it uses three wires and in its standard form consists of three RCA connectors; in some monitors, both interfaces can even be implemented through one set of connectors, switched to "component" or "composite" modes in the settings. The peculiarity of this standard is that it allows you to transmit both picture and sound: one of the wires is used for the analogue video signal, and the remaining two are responsible for the left and right stereo channels. However the composite interface is considered outdated: due to video transmission over a single cable, the quality and noise immunity of the picture are low, and there is no talk of HD resolutions at all. On the other hand, such outputs are still quite popular in video technology — both modern and frankly outdated (like VHS VCRs). And the ability to connect both video and sound at once is very convenient. However, if the monitor has neither audio outputs nor built-in speakers, it usually provides a stripped-down version of this connector — "composite video", with one RCA jack.

— Coaxial (S/P-DIF). An electrical version of the S / P-DIF interface: through one coaxial RCA connector (tulip), sound is transmitted digitally, including multichannel. This connector is found mainly among large-format plasma and LCD panels (see "Type"), where it plays the role of an output for connecting external audio systems — primarily home theaters and other advanced multi-channel acoustic sets.

— Linear. The line interface is a standard audio interface for transmitting an audio signal in analogue format. In general, the most popular way to use this connector is to output sound to active speakers and/or an external amplifier. However, monitors can have both outputs and inputs of this type. In this sense, the line interface is similar to the 3.5 mm jack described above; moreover, in some models, the mini-Jack plays the role of a linear connector.

— Optical. Another type of S / P-DIF connector, in addition to the coaxial output described above. It is used for the same purpose — to output multi-channel sound to external acoustics — however, it uses not an electrical, but an optical (light-guide) cable, so that such a connection is absolutely not subject to electrical interference. On the other hand, optical fibre requires careful handling, as it can crack from bending or strong pressure. It is also worth noting that, unlike coaxial, the optical output is found in both large and relatively small monitors.

— COM port (RS-232). Universal digital interface for transferring various data. In monitors, it usually plays an auxiliary role: it allows you to control the screen settings from a connected computer or other device, and in models with touch screens it can also be used to transfer data from the sensor to the computer. It is much less common than USB, it is practically not used in laptops, but it has the advantage of a maximum cable length — 15 m versus 5 m.

— KVM switch. The presence of a KVM switch in the monitor - Keyboard, Video, Mouse. This module allows you to control two or more computers using one monitor, one keyboard and one mouse, quickly switching between different PCs (for example, a desktop computer and a laptop). A KVM switch improves productivity when you need to use multiple computers at the same time or one at a time and eliminates desktop clutter. To switch from one computer to another, just one click of the mouse in the proprietary software or a programmed button on the keyboard is enough.

— Light sensor. A sensor that monitors the brightness of ambient light. It is mainly used to automatically adjust the brightness of the monitor itself to the specifics of the situation: for example, if the room gets dark, the image on the screen can also be made dimmer, and under sunlight for normal visibility, the brightness should be high. This provides additional comfort for the user and also contributes to energy savings.

— Presence sensor. A sensor that detects the presence of a person in front of the screen. Most often used to automatically control sleep mode: if there is no one in front of the monitor for a certain time, the screen backlight turns off, and when the user returns, it turns back on. This contributes to energy savings and increases the life of the matrix. In addition, the sensor can b...e useful for more specific tasks — for example, to control the presence of an employee at the workplace.

— PBP (Picture by Picture). Possibility to display two "images" on the monitor at the same time — from two different sources, each of which is connected to its own video input. This feature can be very useful in cases where you have to work with two devices at the same time — for example, with a laptop and the main system unit. The image from both devices is usually displayed side by side. Note that for PBP to work effectively, the screen must be quite large, so this function is found mainly among monitors with the appropriate diagonal — from 27 "and above.

— Flicker Free. Brightness control technology that eliminates excessive screen flicker. The idea of this technology is to reduce the brightness of the image directly by reducing the brightness of the backlight (whereas in monitors without Flicker Free, the brightness is adjusted by turning the backlight on and off at a high frequency). Due to the absence of flicker, the load on the eyes and nervous system is reduced, and working with the monitor (especially for a long time) becomes more comfortable.

— AMD FreeSync. Monitor compatible with AMD FreeSync technology. As the name suggests, this technology is used in AMD graphics adapters — so it's worth looking for a monitor with this compatibility if your computer has an appropriate graphics card. And the general idea of FreeSync is to match the frame rate of the monitor and the frequency of the video signal from the graphics card. Such a need arises in the light of the fact that in some cases the frame rate of the video signal can “float” (this is especially true for modern games and other resource-intensive tasks); and a mismatch with the monitor's refresh rate can result in jaggies, jerks, and other artifacts. FreeSync avoids this.
Note that in this case we are talking about the original version of this technology — support for FreeSync Premium and Premium Pro is indicated separately, for these versions, see below. A similar solution from NVIDIA is called G-Sync; it is also described below.

— AMD FreeSync Premium Pro. The most advanced (at the beginning of 2020) version of the FreeSync technology described above, formerly known as AMD FreeSync 2 HDR. As the first name implies, one of the features of this version is HDR support. In addition, FreeSync Premium Pro claims a frame rate of at least 120 fps at Full HD resolution, as well as low frame rate compensation (LFC). The essence of this function lies in the fact that when the frame rate of the source video signal falls below the minimum frequency supported by the monitor, the same frame is displayed on the screen several times, which allows you to maintain the maximum smoothness of the “picture”. According to the creators, FreeSync Premium Pro works especially well in games; and many modern games are originally designed to work with this technology.

— AMD FreeSync Premium. An intermediate option between the basic AMD FreeSync technology and the advanced FreeSync Premium Pro. Both of these versions of the technology are described in more detail above; and FreeSync Premium does not have HDR support (unlike the Pro version), but works at the same frame rate (at least 120 fps at 1920x1080 resolution) and also uses LFC low frame rate compensation technology.

— NVIDIA G-Sync. A technology for matching the frame rate of the monitor and the frame rate of the video signal used in NVIDIA video cards. The need for such coordination arises due to the fact that in some cases the frame rate of the video signal can “float” (this is especially true for modern games and other resource-intensive tasks); and a mismatch with the monitor's refresh rate can result in jaggies, jerks, and other artifacts. A similar technology from AMD is called Freesync (see above).
Note that in this case it means support for the original G-Sync technology, which was originally incorporated during production. Support for the more advanced G-Sync Ultimate, as well as G-Sync Compatible compliance, are listed separately (see below).

— NVIDIA G-Sync Ultimate. A variation of the G-Sync technology described above, which provides not only for matching the frame rate with the graphics card, but also for a number of improved characteristics of the monitor itself. So, models with this marking necessarily support HDR (and according to a very high standard — not lower than DisplayHDR1000), and also have an extensive colour gamut, often measured by DCI P3 (see above for both). Most of these monitors are gaming monitors (see "Type").

— NVIDIA G-Sync compatible. This feature is indicated for monitors that were not originally designed for use with G-Sync technology (see above), but according to the results of testing, they turned out to be compatible with it. All such devices are models with the AMD FreeSync function (also described above), which were tested by nVIDIA and showed the ability to fully work with G-Sync as well (however, we emphasize that FreeSync support by itself does not yet guarantee compatibility with G-Sync) . Anyway, from the user's point of view, the difference lies in the fact that G-Sync Compatible monitors are much cheaper than their counterparts with G-Sync, but may be inferior to them in picture quality. This is due to the fact that these monitors do not undergo additional image quality tests that are required for devices with native G-Sync support. In addition, in G-Sync Compatible models, correct frame synchronization when working with NVIDIA video cards is guaranteed only if the graphics card is based on the GeForce GTX 10-series and GeForce RTX 20-series GPUs — these are the adapters that compatibility testing is carried out on.

— Adaptive Sync. Screen support for VESA Adaptive-Sync technology. The feature aims to synchronize the display's refresh rate with the GPU's frame rate to reduce latency, minimize artifacts, and eliminate visual tearing. Adaptive-Sync certified screens should run at a default refresh rate of 120Hz, but should be able to drop the frame rate down 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 version 1.2a or later.

— CalMAN certification. The monitor has a CalMAN Verified certificate. This certification is given to high-quality screens after they have been tested and calibrated using CalMAN, a professional suite of software tools used for colour manipulation and sensor colour adjustment. The accuracy of these tools is such that even Hollywood filmmakers use them; and in the case of monitors, CalMAN certification is an additional sign of high quality — it means that the colours on such a screen will be displayed as faithfully as possible. Such models are intended mainly for professionals working with colour, as well as for connoisseurs of high-quality video content.

— Pantone certified. The presence of the monitor certificate "Pantone Validated" — that is, a certificate of compliance with the Pantone colour system (PMS). This 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 monitors, 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, monitors with such certification may have different colour gamuts — both in percentage 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.
