This article covers Dell ALIENWARE AW3821DW 37.5インチ 曲面 ゲーミングモニター ディスプレイ (3年間無輝点交換保証.

Overview

The Dell ALIENWARE AW3821DW is a 37.5-inch ultrawide curved gaming monitor designed for immersive gameplay. With a 3840×1600 resolution (WQHD+) and a 21:9 aspect ratio, it delivers a wide field of view ideal for racing, flight sims, and open-world titles. The IPS panel features a 2300R curvature, 144Hz refresh rate, and 1ms response time (Extreme mode), ensuring smooth and responsive visuals. NVIDIA G-SYNC Ultimate support eliminates screen tearing and stuttering, while DisplayHDR 600 certification and 95% DCI-P3 color coverage bring vibrant, high-contrast images. Dell backs the monitor with a 3-year zero-bright-pixel warranty, adding peace of mind for long-term use.

Connectivity & Compatibility

The monitor offers one DisplayPort 1.4 and two HDMI 2.0 inputs. For full 144Hz at native resolution, use the DisplayPort connection; HDMI tops out at 85Hz. A built-in USB 3.2 hub includes one upstream and four downstream ports, plus a headphone jack and audio line-out. VESA 100mm mounting is supported, and the included stand provides height, tilt, and swivel adjustments. G-SYNC Ultimate requires an NVIDIA GeForce RTX GPU and works only over DisplayPort. The monitor is also compatible with AMD FreeSync in a limited capacity, but G-SYNC is the primary feature. Dual-monitor setups benefit from the slim bezels, though the 37.5-inch width demands substantial desk space.

Product Info

Released in late 2020, the AW3821DW remains a high-end choice for ultrawide gaming. It typically retails around ¥119,680 () and competes with models like the LG 38GN950 and ASUS PG38UQ. Accessories include power cable, DisplayPort cable, Mini DisplayPort cable, and USB upstream cable. The 3-year warranty with zero-bright-pixel coverage is a standout perk. As a premium offering, it targets enthusiasts who prioritize visual fidelity and smooth performance. Despite being a few years old, its specifications still hold up well against newer monitors, especially in the 37.5-inch ultrawide segment.

Best Use Cases

This monitor excels for immersive gaming—particularly racing, flight simulation, and story-driven RPGs where the wide aspect ratio enhances the experience. It’s also a strong fit for creative professionals who need accurate colors for video editing or graphic design. The large screen allows efficient multitasking with multiple windows side by side. However, the AW3821DW is best paired with a high-end NVIDIA GPU to fully utilize G-SYNC Ultimate. It is not ideal for small desks due to its size. Competitive FPS players may prefer a smaller, higher-refresh-rate panel, but for an all-round immersive setup, this monitor delivers outstanding value.
