Description

This LG UltraGear 34GX900A-B, 34" gaming monitor with a UWWQHD 3440x1440 resolution delivers incredible detail precision and brightness, making each game scene truly vivid. Such a format is perfectly suited for expansive game worlds and provides advantages due to its wide field of view.

The OLED display uses organic light diodes that shine individually, without background illumination. This ensures perfect black color, high contrast, and fast pixel response, as well as uniform brightness, wide viewing angles, and minimal lag in dynamic scenes.

AMD FreeSync provides adaptive monitor refresh rate with variable frequency range. It helps to prevent image tearing that occurs due to unsynchronized frame output. The technology improves motion uniformity and stability, especially in situations with variable frame frequency.

NVIDIA G-SYNC technology controls panel refresh at the hardware level and adapts it to the current frame rate. This reduces desynchronization and image juddering, improving motion smoothness. The solution ensures a stable display of rapidly changing scenes without an increase in delay.

This monitor with a frequency of 240 Hz ensures maximum smooth motion and minimal reaction lag, which is critical in e-sports games. The high frequency helps track fast objects precisely, reduces blurring, and ensures image stability during rapid movements, improving professional players' control and reaction speed.

Flicker-Free reduces the frequency flickering common to some brightness adjustment methods. This reduces visual stress and ensures a smooth, pleasant image for the eyes. The technology is particularly useful for working in darker rooms and during prolonged viewing sessions.

The Swivel mechanism allows for changing the horizontal angle of the screen without moving the entire structure. This facilitates workspace adjustment, improves visibility from different points and helps adjust the monitor for various usage scenarios, including configurations for multiple users or multiple monitors.

Tilt technology allows for adjusting the screen's slope angle back and forth, ensuring the correct image placement in relation to the user's line of sight. This kind of adjustment helps reduce neck and eye strain, improves image perception, and makes long-term work at the monitor more comfortable.

VESA wall mount allows you to install a monitor on the wall, adhering to a uniform industrial standard. It facilitates the choice of mount, increases the flexibility of workspace organization, and allows you to adjust the height and angle of placement, regardless of the desk or tripod.

Built-in speakers allow the monitor to independently process and play audio signals, reducing the need for additional devices. This makes the workplace more compact and facilitates connection. The speakers provide basic sound support for multimedia and communication applications.

HDMI is a digital interface designed for stable video and audio transmission with a single cable. This approach reduces the number of connections and prevents unnecessary signal conversion. HDMI ensures a reliable connection, high throughput, and precise operation with modern devices without loss of quality.

DisplayPort is a modern interface that allows stable image transmission with high resolution and refresh intensity. The interface is compatible with professional and gaming monitors, supports multiple monitor configurations and HDR, ensuring accurate detail transmission and minimal graphics distortion.

The USB-C connection provides video, audio, and power transmission through a single cable, reducing the number of wires and facilitating the connection. It offers fast data transmission and a stable picture, making the monitor convenient for use with modern laptops and mobile devices without multiple separate connections.

Several USB-C ports make the monitor more versatile for modern devices. Each port can simultaneously transmit video, audio, data and power through a single cable, reducing the number of wires. This allows to connect multiple peripheral devices or signal sources without additional adapters.

USB Power Delivery provides device charging directly from the monitor, reducing the need for separate power blocks. It simplifies device placement and reduces the number of wires. Parallel charging and signal transmission makes the connection more functional and versatile.

USB-C video input ensures the transmission of video and audio signals through a single cable, simplifying the connection and reducing the number of wires. The connector supports modern data transmission protocols and ensures a stable signal. It improves the monitor's compatibility with a wide range of modern devices.

Panel Type OLED

Teh monitor panel is the main feature of the visible part of the screen or the technology where the display of the colour dots (pixels) is implemented.

TN is the standard technology with average contract, brightness and colour compliance indices.

IPS is the matrix with high colour compliance and good response speed, therefore it is well suited for graphics tasks and photo editing. IPS matrix provide an excellent viewing angle maintaining the colours and contrast from almost any angle.

VA matrix ensures superior colour compliance, however, the response time of this matrix is lagging behind that of the IPS and TN; the viewing angle is somewhere between both these technologies.

The TN type monitor is fully sufficient for an average user. If you have more money available the VA or IPS can be chosen.

Refresh rate : 240 Hz
Touchscreen : NO
VESA DisplayHDR : DisplayHDR True Black 400
Response time 0.03ms
The response time of the monitor screen determines how fast the monitor will display moving images (films, games, animations, etc.). The response time is measured in miliseconds. The less the response time the better the ability of the monitor to display moving images.
www.toppc.fi recommends to buy monitors with 5ms response time or lower.
Contrast ratio 1500000:1

Ekrāna kontrasts nosaka attēla asumu. Tā ir atšķirība starp vistumšāko (pilnīgi melnu) un visgaišāko (pilnīgi baltu) pikseli. Jo lielāks kontrasts, jo skaidrāk salasāms teksts uz ekrāna, kontrasts arī nosaka, cik izteiksmīgas līnijas būs redzamas monitora attēlā.

Augsts kontrasts ir nozīmīgs faktors izvēloties monitoru biroja, vai mācību vajadzībām, kad lielākoties tiek strādāts ar tekstuālu informāciju.

Mājas vajadzībām svarīgāks izvēles rādītājs ir gaišums un attēla reakcijas laiks. Kontrastu labāk novērtēt tumšā istabā.
Lielākais LCD monitoru trūkums ir tas, ka samazinot attēla spilgtumu, kontrasts var pazust.

Brightness 275cd/m2

Monitora gaišums ir attēla redzamības rādītājs, kas nosaka, cik labi saskatāms ir attēls pie spēcīga ārējā apgaismojuma (saules gaisma, gaiša telpa, utt.). LCD monitoru gaišums tiek mērīts kandelās uz kvadrātmetru (Cd/m2).
Izvēloties monitoru jāņem vērā - jo lielāks gaišuma rādītājs, jo labāka attēla redzamība.

Ikdienas vajadzībām TopPC.fi iesaka iegādāties monitoru ar gaišumu, ne mazāku par 250 cd/m2.

Basic information
Application : Gaming
Aspect ratio : 21:9
Color : Black
Size 34"

The size of the monitor screen is measured in inches across the diagonal. The screen size must be proportionate to the resolution of the screen for achieving the maximum utilisation of the desktop and details of the image.

Mainly two forms of LCD monitors are available: with standard width and height proportion 4:3 or the widescreen proportion 16:9 or 16:10. A widescreen monitor is wider and its resolution is higher than that of the monitors with standard proportion.

The bigger the monitor size the higher resolution usually is supported. Possibilities to increase the resolution of the screen usually depend on the size and possibilities of the monitor and the type of the video card.

Resolution UWWQHD 3440x1440

The resolution of the monitor screen determines the number of colour dots (pixels) a monitor can display. It refers to the clarity of the text and images displayed on the screen. The higher the resolution the sharper the items look.

The applied resolution depends on the resolution supported by the monitor. LCD monitors, including the screens of laptop computers usually work best if their local resolution has been set. The setting of this resolution for the monitor is not mandatory, but usually it is recommended to set it for ensuring the highest possible sharpness of texts and images. The bigger the monitor size the higher resolution usually is supported.

Possibilities to increase the resolution of the screen usually depend on the size and possibilities of the monitor and the type of the video card.
• 19 inches screen (standard proportions): 1280x1024 pixels
• 20 inches screen (standard proportions): 1600x1200 pixels
• 22 inches screen (widescreen): 1680x1050 pixels
• 24 inches screen (widescreen): 1900x1200 pixels

Ports and equipment
D-SUB Nav

D-SUB is the classic (analogous) monitor connection plug. This standard is gradually disappearing from the market giving the place to the higher quality HDMI or DisplayPort (digital) plugs.

If the resolution of the monitor is FullHD or below the average user will experience no problems with this connection. Those who want to achieve higher image quality and resolution should look for the monitor with the DisplayPort or HDMI connection slot.

DisplayPort 1

DisplayPort is the digital connection for transmitting the image via a single wire at a high quality level. Contrary to the HDMI, this connection allows to connect several external monitors to the computer via a single connector.

Prior to buying the monitor with the DisplayPort you should verify whether your computer has the DisplayPort plug available!

DVI Nav

DVI is a digital standard and ensures high image quality, however, thanks to the big size of the plug and the inability of the standard to develop further due to a few technical restrictions this type of connection is gradually losing its popularity to modern HDMI and DisplayPort standards.

DVI is compatible with HDMI and transitions of both directions are available.

DVI is not compatible with DisplayPort, however, there are DualMode DisplayPort connectors which contains the HDMI/DVI signal, and in the relevant direction DisplayPort -> DVI can transmit an image.

If the monitor resolution exceeds 1920px in any direction a graphics card with the DVI-D Dual Link support and the relevant quality cable will be required.

Before buying a monitor you should verify whether your graphics card has the corresponding connection slot!

HDMI port 2

HDMI is the digital high quality image transmission standard that allows to connect the monitor to the computer via a thin cable by using an elegant small-size connector. HDMI is compatible with DVI if the relevant transition or cable is used.

Speakers Ir

Some monitors may have built-in speakers that quite often allow to give up external speakers thus freeing a space on the desk and saving money. The sound quality of built-in speakers is quite moderate and therefore we recommend to use this possibility just for infrequent needs.

For enjoying music, movies and games we recommend buying the corresponding quality and capacity speakers.
