Comparison LG 24MP48HQ 24 " vs LG 24MP58VQ 24 "

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).

— 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).

— 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 a...llow using the 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.

Rated power consumption of the monitor. Usually, this item indicates the maximum power that the device can consume during normal operation — that is, the energy consumption at maximum brightness, the highest volume of the built-in acoustics, etc. Actual power consumption can be noticeably lower, however, when choosing, it is still best to focus on the value stated in the specifications.

In general, the lower the power consumption, the more economical the device in terms of electricity consumption (ceteris paribus). In addition, this characteristic can be useful when selecting an uninterruptible power supply for a PC and in other specific situations when it is necessary to accurately determine the power consumption of equipment.
