The Dell Alienware AW3926QW is a high-end 39-inch ultrawide OLED gaming monitor. It features a curved and glossy screen with a 5120x2160 resolution. It's the first monitor in this size class to feature a WOLED panel with an RGB subpixel layout, so it doesn't have a dedicated white subpixel like on some competing models, like the LG 39GX950B-B. This is meant to improve text clarity by reducing fringing around letters. Although it has a native 165Hz refresh rate, you can boost it to 330Hz with a lower 2560x1080 resolution by using its dual-mode feature. It has gaming features you'd expect to find in a high-end model, like high-bandwidth DisplayPort and HDMI inputs alongside FreeSync Premium Pro and G-SYNC Compatibility to reduce screen tearing. Besides that, it uses Tandem OLED technology to boost its brightness, and it's certified for VESA DisplayHDR TrueBlack 500. Plus, it supports Dolby Vision to take advantage of sources that also support it, like an Xbox Series X|S.
Our Verdict
The Dell AW3926QW is incredible for PC gaming. You can choose between its 5k2k @ 165Hz and 2560x1080 @ 330Hz modes, offering versatility for different types of games. Motion looks sharp at any refresh rate, it has low input lag, which is ideal for reaction-based games, and it supports all common VRR formats to reduce screen tearing. However, it has distracting VRR flicker with fluctuating frame rates in dark scenes. On the plus side, its 39-inch screen offers an immersive gaming experience, and it delivers remarkable picture quality. It also displays deep blacks in any room, highlights pop, and colors are vivid for an impactful HDR experience.

The Dell AW3926QW is fantastic for console gaming. It supports any signal with a modern gaming console, including Dolby Vision with an Xbox Series X|S. However, keep in mind that you'll see black bars on the sides as consoles don't support ultrawide formats. Motion looks sharp thanks to its fast response time, and its low input lag makes it a fantastic choice for playing games that need fast reactions. Plus, it's superb for HDR gaming as it displays deep and inky blacks without any haloing around bright objects. Highlights also pop, and colors are vivid.

The Dell AW3926QW is good for office use. It has a high resolution with high pixel density, and text looks sharp without any fringing thanks to its RGB subpixel layout. Its 39-inch curved screen also makes it easy to multitask with different windows open. It even has some productivity features, like a small USB hub that includes a USB-C port with DisplayPort Alt Mode and 90W of power delivery to a laptop. It's fine if you want to use it in a room with a few lights around, but reflections are distracting if you have it in front of a sunny window. It also risks burn-in with constant exposure to the same static elements over time, like if you only use it for work.

The Dell AW3926QW is superb for content creation. It's remarkably accurate out of the box, with a full calibration only fixing a few minor white-balance and gamma-tracking issues. It also displays a wide range of vivid colors and has deep blacks in any environment. Images look sharp thanks to its high resolution and pixel density, and its glossy coating makes content look clear. However, the downside of this coating is that there are strong mirror-like reflections, so you need to avoid using it in front of a sunny window. Unfortunately, it risks burn-in with constant exposure to the same static elements over time, like if you only have your editing program open all the time.

Popular Monitor Comparisons
The Dell AW3926QW is a premium ultrawide OLED gaming monitor with a 39-inch screen and 5k2k resolution. Featuring a 165Hz native refresh rate, it offers a dual mode to boost it to 330Hz with a lower 2560x1080 resolution. Despite there being other dual-mode options in the market, it has a unique position because of its size, providing enough screen real estate for an immersive gaming experience while also having high enough pixel density for detailed images. Plus, it's the first WOLED of its size to feature an RGB subpixel layout, dropping the white subpixel found on older models, like the LG 39GX950B-B. The advantage is that it doesn't have color fringing around letters, so text is as sharp as it could be with a monitor of its size and resolution.
Besides that, it comes with typical gaming features, like DisplayPort and HDMI 2.1 bandwidth, support for all common VRR formats, and sharp motion at any refresh rate. Its Dolby Vision support is even useful if you have a source that also supports it, like an Xbox Series X|S. It also has a glossy coating that makes images look clear and maintains low black levels in a bright room. Overall, you're getting a typical OLED gaming monitor in a big screen with improved text at a reasonable price for a premium model. If you want a monitor of this size, you can't go wrong with it.

We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
