Comparison Asus ROG Strix XG32UQ 32 " black vs Asus ROG Swift PG329Q black

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 stil...l commonly referred 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 vertical 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.

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.

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.

Display certification for safe blue light emissions and panel flicker. The presence of a certificate confirms the comfort of the screen for the eyes.

TÜV Rheinland is a large international concern headquartered in Cologne, Germany, providing a wide range of audit services. The company's specialists have developed and approved a number of tests for the compliance of the screens of mobile devices, monitors and TVs with the required level of eye protection from the harmful effects of display radiation on the user's vision on the other side of the screen. The authoritative opinion of TÜV Rheinland is respected in the tech community. Certificates from this body are issued to successfully tested electronics for the implementation of blue light filtering and screen flicker suppression technologies.

— VGA. A connector designed for transmitting analog video signals back in the era of CRT monitors (especially for them). Today it is considered obsolete and is gradually falling out of use - in particular, due to low bandwidth, which does not allow full work with HD content, as well as double signal conversion when using VGA in LCD monitors (which can become a potential source of interference) .

— DVI. A connector for video signal transmission, designed specifically for LCD devices, including monitors. Although the abbreviation DVI originally stands for “digital video interface,” this interface also allows analog data transmission. Actually, there are three main types of DVI: analog, combined and digital. The first type in modern computer technology has almost gone out of use (this function is actually performed by the VGA connector), and a purely digital connector - DVI-D - is indicated separately in our catalog (see below). Therefore, if the monitor’s specifications indicate “just DVI”, most likely we are talking about a combined DVI-I connector. In terms of the characteristics of the analog video signal, it is similar to the VGA described above (and is even compatible with it through a simple adapter); in terms of digital capabilities, it is DVI-D (single-channel, not Dual Link). However, due to the spread of purely digital standards, DVI-I is becoming less...and less common.

— DVI-D. A variation of the DVI interface described above that supports exclusively digital video signal format. The standard (Single Link) DVI-D interface allows you to transmit video in resolutions up to 1920x1080 at a frame rate of 75 Hz or 1920x1200 at a frame rate of 60 Hz, which is already enough to work with modern resolutions up to Full HD inclusive. In addition, there is a dual-channel (Dual Link) version of this connector, which has increased bandwidth and allows you to work with resolutions up to 2560x1600 (at 60 Hz; or 2048x1536 at 75 Hz). Accordingly, the specific DVI-D type depends on the monitor resolution. In this case, a single-channel screen can be connected to a dual-channel video card, but not vice versa. Also note that the situation with connectors is similar: Single Link and Dual Link ports are slightly different in design, and a single-channel cable is compatible with dual-channel input/output, but, again, not vice versa.

— DisplayPort. An interface originally created for video transmission (however, it can also be used for audio signals - in this DisplayPort is similar to HDMI). Found in many modern monitor models. Note that monitors with DisplayPort inputs are also compatible with Thunderbolt outputs (via an adapter).

The specific capabilities of this connector depend on its version. Modern monitors have the following options:

• v.1.2. The earliest version commonly used in our time, released in 2010. It was there that features such as 3D support and the ability to connect multiple screens in a daisy chain were first introduced. Version 1.2 allows you to transmit 5K video at a frame rate of 30 fps; working with higher resolutions (up to 8K) is also possible, but with certain restrictions.
• v.1.3. DisplayPort version released in 2014. It has one and a half times more bandwidth than v.1.2, and allows you to transmit 8K video at 30 fps, 5K at 60 fps and 4K at 120 fps. In addition, this version has a Dual-mode function, which allows you to connect to HDMI and DVI outputs through simple passive adapters.
• v 1.4. In this version, the maximum frame rate when working with one screen has increased to 120 fps for the 8K standard and to 240 fps for the 4K and 5K standards (data is supposed to be transmitted with compression using DSC - Display Stream Compression technology). Other features include compatibility with HDR10 and the ability to simultaneously transmit up to 32 channels of audio.
• v2.1. 2022 version using the same physical layer specification as USB4. The interface bandwidth has been doubled compared to v 1.4 (up to 80 Gbit/s, of which 77.37 Gbit/s is available for data transfer). At the same time, it supports connecting displays with resolutions up to 16K at 60 fps, 8K at 120 fps, 4K at 240 Hz and 2K at 480 Hz (without the additional use of DSC - Display Stream Compression technology). DP40 (40 Gbps) cables can now be longer than two meters, while DP80 (80 Gbps) cables can be more than one meter long.

— Mini Display Port. A smaller version of the DisplayPort described above, used primarily in laptops; especially popular in Apple laptops. Recently, there has been a trend towards replacing the Mini Display Port with a universal Thunderbolt interface; however, this interface operates through the same connector and provides the same capabilities. In other words, monitors can be connected to Thunderbolt (versions 1 and 2) via a standard miniDisplayPort cable, without using adapters (for v3 you will still need an adapter).

— HDMI. The HDMI interface was originally designed to transmit high-definition video and multi-channel digital audio over a single cable. This is the most popular of modern interfaces for this purpose; HDMI outputs are practically mandatory both for computer video cards and for media centers, DVD/Blu-ray players and other similar equipment.

The presence of several outputs of this type in the monitor allows you to keep it connected simultaneously to several signal sources - for example, a computer and a satellite TV tuner. This way you can switch between sources through software settings without fiddling with reconnecting cables, and also use the PBP function.

At the same time, the port itself has different versions, and the most common in our time are as follows:

• - v.1.4. The earliest version actively used in our time; appeared in 2009. Supports resolutions up to 4096x2160 at 24 fps, and in the Full HD standard (1920x1080) the frame rate can reach 120 fps; 3D video transmission is also possible.
• - v.2.0. Version introduced in 2013 as a major update to the HDMI standard. Supports 4K video with frame rates up to 60 fps (due to which it is also known as HDMI UHD), as well as up to 32 channels of audio and up to 4 audio streams simultaneously. Also in this version there is support for ultra-wide format 21:9.
• - v.2.1. Quite a significant update compared to version 2.0, introduced at the end of 2017. A further increase in throughput made it possible to provide support for resolutions up to 8K at 120 fps inclusive. Improvements have also been made regarding working with HDR. Note that to use all the features of HDMI v 2.1 you need HDMI Ultra High Speed cables, although basic functions are available with regular cables.

— USB C (DisplayPort AltMode). Another type of USB interface used to work with video signals. It has a small size (not much larger than a microUSB) and a reversible design that allows you to connect the plug to either side - this makes Type C more convenient than previous standards. At the same time, we note that such a monitor may initially be designed for connection to a USB C output (at least, such an adapter cable may be supplied in the kit); it would not hurt to clarify this point separately.

— Thunderbolt interface. Thunderbolt is a data transfer protocol (used in Apple devices), the throughput of which reaches 40 Gbps. The connector itself, as well as the speed, depend on the version: Thunderbolt v1 and v2 use miniDisplayPort (see above), monitors with Thunderbolt inputs are not necessarily compatible with the original miniDisplayPort outputs - it wouldn’t hurt to check this compatibility separately. And Thunderbolt v3 is based on the USB C connector (see above).
