The LG UltraGear 45GX950A-B OLED monitor is a 44.5-inch (113 cm) curved computer monitor designed for demanding gamers, content creators and professional users looking for an exceptional visual experience and advanced connectivity. The monitor belongs to the class of gaming monitors of the highest quality level, with OLED technology enabling deep blacks and vivid colors, and the 21:9 aspect ratio offers additional width for a better view of the action.

Thanks to the WUHD 5120 × 2160 resolution and an extremely fast 0.03 ms response time, the monitor provides a smooth image and sharp display of details even in dynamic scenes. The 800R curvature of the screen creates a feeling of complete immersion in the content, which is especially noticeable when playing games or working with multiple program windows at the same time.

Key product features

⚖️ Compare features with other products of your choice

The use of an OLED panel allows for accurate display of both deep shadows and strong, vivid colors. This is especially important for photo editing, watching movies, playing games with stunning visual effects, or work where color accuracy and exceptional contrast are essential. The maximum refresh rate of up to 330 Hz (in Overclock mode) allows for extremely smooth display of fast motion without blurring or lag, which can significantly affect the gaming experience in fast-paced action games.

The built-in docking station (90W) allows you to connect your laptop and simultaneously power, transfer images and data via USB-C, simplifying work in modern home or business environments. The 800R curvature ensures more ergonomic viewing with less eye strain during prolonged use, especially on such a large screen area. The 21:9 aspect ratio provides additional width for multitasking, allowing you to display multiple different windows or applications at the same time.

The monitor supports DisplayHDR True Black 400, which means a greater variety of dark shades and better detail in dark scenes, especially when watching movies or creating content. Although the brightness of 275 cd/m² is not the highest in this category, thanks to OLED technology it is still enough for a rich and contrasting display in most indoor spaces.

It is important to know

Choosing a curved OLED monitor with an extremely large diagonal and ultra-high resolution brings significant advantages and some specific challenges that are not obvious from the technical specifications alone. It is important to consider how the spatial layout, usage and connectivity affect your real needs, especially when working, gaming or creating.

• Due to the 44.5-inch diagonal and curvature, it is recommended to provide a sufficiently deep and wide desk, as too little workspace can significantly reduce usability and ergonomics.
• The WUHD resolution on this surface provides above-average space for multiple applications or split-screen work, but some programs and operating systems may require additional display adjustments (scaling, window space arrangement).
• The OLED panel brings advantages for color-accurate work and darker environments, but requires responsible selection of the lighting environment and consideration of possible traces of static images during long-term monotonous use.
• A high refresh rate allows for a very smooth user experience, but to take advantage of this advantage, you need a suitable computer and a more powerful graphics card with appropriate connectors.
• An alternative to a dual-monitor setup—the ultrawide model offers better workspace continuity, but you should decide before purchasing whether it's the best approach for your daily tasks and tools.

In practice

🟢 Multitasking and advanced office work

The extremely wide work surface and high resolution provide a very good starting point for working with multiple applications at the same time and advanced window organization without the need for an additional monitor.

🟢 Gaming and fast-paced visual content

The combination of OLED technology, a curved panel, and a high refresh rate delivers an excellent experience for demanding games and complete immersion in the image.

🟢 Creative work and graphic content processing

The large surface area, precise colors and contrast, and wide viewing angle make the monitor well-suited for creators who need precision and spaciousness.

🟡 Working on smaller tables or in limited space

The size and curvature of the monitor may limit placement in smaller spaces or on shallow desks; proper distance must be maintained for an optimal experience.

🟡 Easy connection to all devices

Advanced connection options require attention to choosing the right cable and checking the compatibility of the graphics card and connectors on the computer, especially if you want to take advantage of the highest resolutions and frequencies.

Answers to frequently asked questions

Is normal use possible on a regular office desk with this monitor size?

In most cases, a greater depth and width of the desk will be required for optimal monitor placement, otherwise several ergonomic compromises are possible.

Does an ultrawide monitor effectively replace two classic monitors?

For most scenarios, the ultrawide model provides a single wide work surface without a frame in the middle, but some users are still more satisfied with two separate monitors due to the possibility of individual settings.

How demanding is it to connect to a computer for maximum resolution and refresh?

You will need a suitably powerful graphics card and the right cable (most often DisplayPort or HDMI of the latest generations) to fully utilize the monitor's capabilities.

Does the OLED panel require special handling due to the possibility of imprinted static images?

Displaying a static image on OLED panels for a long time can gradually leave traces, so it is recommended to use functions to prevent burn-in or regularly change the content on the screen.

What do I need to check if I want to use the monitor with my laptop?

Before purchasing, check whether your laptop supports the required resolution and refresh rate and whether it has an appropriate output (e.g. DisplayPort/Thunderbolt/HDMI) that allows connection to a monitor.
