This article covers Dell AW3425DW 34インチ曲面 有機EL Alienware ゲーミングモニター(無輝点3年保証. The Dell AW3425DW is a 34.2-inch curved QD-OLED gaming monitor from the Alienware lineup.
It features a 3440×1440 (WQHD) resolution with a 21:9 ultrawide aspect ratio and an 1800R curvature designed to pull you into the action. With a 240Hz refresh rate and 0.03ms (GtG) response time, it delivers the speed needed for competitive gaming.
The standout feature is the QD-OLED panel, which covers 99.3% of the DCI-P3 color space and carries VESA DisplayHDR True Black 400 certification for deep blacks and vibrant highlights.
It supports three variable refresh rate technologies — NVIDIA G-SYNC Compatible, AMD FreeSync Premium Pro, and VESA AdaptiveSync — ensuring tear-free gameplay across a wide range of GPUs. Video inputs include one DisplayPort 1.4 and two HDMI 2.1 ports.
HDMI 2.1 provides 48Gbps bandwidth, enabling 4K 120Hz or variable refresh rate support.
There is no built-in USB hub, but a rear cable slot helps keep your desk tidy. The monitor is VESA mount compatible (100×100mm) and offers height adjustment (up to 110mm) and tilt adjustment (-5° to 21°).
It works with both NVIDIA and AMD GPUs thanks to its multi-VRR support. Note that G-SYNC Compatible mode is only available over DisplayPort, while FreeSync Premium Pro works over both DisplayPort and HDMI.
Released in 2025, the AW3425DW typically sells for around ¥60,000 (approx. $400 USD) as of mid-2026.
It comes with a 3-year zero-bright-dot warranty and an advanced replacement service — Dell sends a replacement unit before you return the defective one. Accessories include power cable, DisplayPort cable, HDMI cable, USB upstream cable, and a quick setup guide.
Positioned as a high-end gaming monitor, the AW3425DW offers QD-OLED quality at a price that undercuts many competitors like the Samsung Odyssey G8 OLED. The trade-off is the lack of USB hub and KVM functionality, which some users may miss.
Competitive FPS gamers: The 240Hz refresh rate and 0.03ms response time provide the responsiveness needed for fast-paced shooters.
Pair it with an NVIDIA GeForce RTX GPU for G-SYNC Compatible tear-free performance. However, if you prefer a smaller 27-inch screen for faster eye movement, this 34-inch panel may feel too large.
Creative professionals: The wide DCI-P3 coverage and Delta E<2 color accuracy make this monitor suitable for photo editing and video color grading. HDR content looks impressive thanks to DisplayHDR True Black 400.
For strict color-critical work, consider a dedicated calibrator since Adobe RGB and sRGB coverage are not officially specified. * Immersive gaming enthusiasts: The 34-inch ultrawide format with 1800R curvature is ideal for racing sims, flight sims, and open-world RPGs.
The 21:9 aspect ratio expands your field of view in supported titles. Be aware that games without ultrawide support will display black bars on the sides.
