This article covers LG 34G630A-B 34インチ ウルトラギア WQHD (3440×1440) 湾曲ゲーミングモニター 240Hz 1ms FreeSync Premium DisplayHDR 400 内蔵スピーカー.

Overview

The LG 34G630A-B is a 34-inch ultrawide gaming monitor with a WQHD (3440×1440) resolution and a 1500R curvature. It delivers a 240Hz refresh rate and a 1ms (GtG) response time, making it an excellent choice for fast-paced shooters and racing games. With AMD FreeSync Premium support, screen tearing and stuttering are virtually eliminated. The monitor is VESA DisplayHDR 400 certified and covers 95% of the DCI-P3 color space, ensuring vibrant visuals for both gaming and content creation. The ergonomic stand offers height, tilt, and swivel adjustments, allowing you to find a comfortable viewing angle for long sessions.

Connectivity & Compatibility

The monitor provides two HDMI 2.0 ports, one DisplayPort 1.4, and one USB Type-C port with 15W Power Delivery. The USB-C connection supports video input and charging simultaneously, making it ideal for laptops. Built-in 2W stereo speakers are included for basic audio output. To achieve the full 240Hz at WQHD resolution, use the DisplayPort input; HDMI connectivity may limit the refresh rate. The monitor works best with modern GPUs from NVIDIA (RTX 30-series and later) or AMD (RX 6000-series and later) to drive the high pixel count and refresh rate.

Product Info

Released in mid-2025, the LG 34G630A-B sits in the mid-to-high-end segment of the gaming monitor market. It is priced around ¥89,000 on major Japanese retailers. LG provides a standard 3-year warranty. The package includes a power cable, a DisplayPort cable, a USB Type-C cable, and a quick setup guide. Compared to competitors like the ASUS ROG Swift PG34WQ or Dell Alienware AW3423DWF, the 34G630A-B offers a compelling balance of core gaming specs and price, though it lacks the high-end HDR peak brightness of OLED alternatives.

Best Use Cases

Competitive gamers: The 240Hz refresh rate and 1ms response time provide a clear advantage in fast-action titles like Valorant, Overwatch, and racing sims. The ultrawide aspect ratio gives a wider field of view, helping you spot enemies earlier. However, some esports games perform best at 16:9, so check compatibility beforehand. Content creators: The WQHD resolution and DCI-P3 95% color coverage make this monitor a solid choice for video editing and photo retouching. The 21:9 ratio is perfect for timeline-based workflows. For professional color grading, a calibration tool is recommended to achieve accuracy. Productivity users: The spacious screen lets you arrange multiple windows side by side, boosting multitasking efficiency. The USB-C connection with 15W charging simplifies laptop docking, reducing cable clutter on your desk. Who should look elsewhere: Budget-conscious buyers may find more affordable 1440p 165Hz monitors sufficient for their needs. If deep blacks and infinite contrast are critical, consider an OLED ultrawide like the Alienware AW3423DWF, though it costs significantly more.
