The slim stand and compact base are noted for their space-saving design, freeing up valuable desk real estate.

The stand offers smooth adjustments for height, tilt, and swivel, allowing users to find an ergonomic viewing position with ease.

Its curved shape is a deliberate choice for gaming immersion, though it is worth noting this may introduce slight distortion for tasks requiring perfectly straight lines, such as detailed graphic design.
Performance and Features
Display and Gaming Performance
The centerpiece of this monitor is its 34-inch WQHD (3440 x 1440) VA panel with a 240Hz refresh rate and 1ms Gray-to-Gray response time. This combination is engineered for high-speed competitive gaming, aiming to deliver fluid motion and minimize ghosting. The 21:9 ultrawide aspect ratio provides significant extra horizontal screen space, beneficial for keeping game overlays, maps, and communication apps visible without alt-tabbing. To achieve the full 240Hz refresh rate, the manufacturer specifies that a graphics card supporting DisplayPort 1.4 or HDMI 2.1 is required. The monitor is also listed as NVIDIA G-SYNC Compatible for variable refresh rate support with certain GeForce GPUs.
Visual Quality and HDR
For color reproduction, the monitor covers up to 95% of the DCI-P3 color gamut and is certified for VESA DisplayHDR 400. This supports richer hues, brighter highlights, and deeper shadows compared to standard dynamic range content, though DisplayHDR 400 represents an entry-level HDR experience. The matte screen finish helps reduce glare. User reviews frequently praise the vibrant and sharp picture quality, noting that colors pop without appearing oversaturated.
Connectivity and Ports
Connectivity is a strong suit for the LG 34G630A-B.AUSQ. It includes two HDMI ports, one DisplayPort, and a USB Type-C port that supports display output, data transfer, and up to 15W of power delivery. This USB-C functionality simplifies connecting a laptop with a single cable. Two USB-A ports are also included for peripherals. The included components are a DisplayPort cable, an HDMI cable, and a power cable.
Gaming and Software Features
Beyond core specs, LG includes several gaming-oriented features under its “UltraGear” suite. AMD FreeSync Premium ensures tear-free and stutter-free gameplay when used with compatible AMD graphics cards. Other utilities include Dynamic Action Sync to reduce input lag, Black Stabilizer to brighten dark scenes, an on-screen FPS counter, and a crosshair overlay for enhanced aiming precision. The monitor also has a Picture-by-Picture mode for multitasking and built-in stereo speakers, which provide basic audio but are not a substitute for dedicated speakers or a headset.
Setup, Support and Ownership
Setup is reported to be straightforward, though users should carefully check all packaging for the necessary screws for the stand assembly. The monitor is VESA mount compatible (100x100mm) for those who prefer an arm or different stand. LG provides a one-year manufacturer’s warranty for this model. As with any high-refresh-rate monitor, users should ensure their system’s graphics hardware and cables are capable of driving the native resolution at the maximum refresh rate to fully utilize the monitor’s potential. The product specifications do not list specific software suites for management, suggesting on-screen display menus are the primary method for adjusting settings.
What Owners Say
Owner feedback for the LG 34G630A-B.AUSQ is overwhelmingly positive, reflected in its high rating distribution where the majority of reviews are five-star. Users consistently highlight the stunning picture quality, buttery-smooth performance at 240Hz, and the immersive effect of the curved ultrawide display. Many describe it as offering exceptional value. The adjustable, stable stand receives frequent praise. Some notes of caution include the monitor’s substantial physical size, which requires adequate desk space, and the reminder that the built-in speakers offer only basic sound quality. A small percentage of critical reviews mention issues, but the prevailing sentiment is that it exceeds expectations for a monitor in its category.

FAQs
Does this monitor work with NVIDIA graphics cards?
Yes. According to the manufacturer’s description, the LG 34G630A-B.AUSQ is NVIDIA G-SYNC Compatible. This means it supports variable refresh rate technology with certain NVIDIA GeForce GPUs (GTX 10 series and higher over DisplayPort, and RTX 30 series and higher over HDMI 2.1) to help reduce screen tearing and stuttering.
What is needed to run this monitor at 240Hz?
To achieve the full 240Hz refresh rate at the native WQHD (3440×1440) resolution, you need a graphics card that supports DisplayPort 1.4 or HDMI 2.1. You must also use a compatible high-bandwidth cable, such as the DisplayPort cable included in the box or a certified HDMI 2.1 cable.
Is the curve of this monitor noticeable for everyday use?
The monitor has a 1500R curvature, which is designed to match the natural curve of the human eye for a more immersive viewing experience. For gaming and media consumption, this is generally appreciated. However, for tasks requiring absolute geometric accuracy, like CAD work or graphic design with straight lines, the curve can introduce a slight perceptual distortion.
Can you mount this monitor on an arm?
Yes. The LG 34G630A-B.AUSQ is VESA mount compatible with a 100x100mm pattern. This allows you to detach the included stand and mount the monitor on a compatible desk arm or wall mount. Be sure the mount can support the monitor’s weight and size.
