Dell Alienware AW3420DW 34" Lunar Light 2020

The Alienware AW3420DW is a 34-inch curved ultrawide gaming monitor with a 3440 x 1440 IPS panel, 120Hz refresh rate, and native G-Sync. It delivers stunning color accuracy and immersive 21:9 visuals at a renewed price of around $635. It's not the fastest or brightest panel anymore, but for ultrawide gaming and productivity, it's still a fantastic buy.

The AW3420DW runs at 120Hz with a 2ms response time, and G-Sync keeps things tear-free if you're on an NVIDIA card. In our database, its performance lands in the 67th percentile, which is solid but not chart-topping. For most gamers, 120Hz on an ultrawide is plenty smooth. You won't get the 240Hz or 360Hz speeds of newer esports panels, but you also won't get the ultrawide immersion on those panels either.

The display itself scores in the 83rd percentile, which is well above average. The 3440 x 1440 resolution is sharp enough that text looks crisp and games look detailed. Color coverage is a real strength here. It hits 98% DCI-P3 and 134.5% sRGB, which puts it in the 79th percentile for color. That's impressive for an IPS panel, and it means this monitor pulls double duty for content creation and media consumption, not just gaming. Brightness tops out at 350 nits, which is fine for indoor use but won't wow you in a sunlit room.

The AW3420DW goes up against some serious modern competition. The ASUS ROG Strix XG27UCDMG is a 27-inch 4K panel that's sharper and faster, but it's smaller and lacks the ultrawide aspect ratio. The LG UltraGear 45GX950A-B is a massive 45-inch ultrawide that makes the Alienware look compact, but it costs significantly more. The MSI MAG 271QPX QD-OLED E2 and Samsung Odyssey G60SD both bring OLED contrast and faster refresh rates, but they're 16:9 panels, so you lose the cinematic width.

Where the Alienware still wins is the combination of size, curve, and color accuracy at this price point. The 1900R curve on a 34-inch panel is a sweet spot for immersion without the fisheye effect you get on more aggressive curves. The G-Sync module is a genuine hardware implementation, not just G-Sync Compatible, which means it works flawlessly across the entire refresh range. If you're on an NVIDIA GPU and want ultrawide gaming without spending OLED money, this is still one of the best options on the market.

At $635 USD for a renewed unit, the AW3420DW is a compelling deal if you want ultrawide immersion without dropping a grand on a new OLED. The original MSRP was significantly higher, so you're getting a premium panel at a mid-range price. That said, the renewed caveat matters. You get a 90-day Amazon warranty instead of Dell's full coverage, and some buyers have reported receiving repaired cables or the wrong color variant. If you're okay with that trade-off, the value is hard to beat. If you want peace of mind, a new ultrawide from LG or ASUS might cost more but comes with fewer question marks.

The Alienware AW3420DW is a 34-inch ultrawide gaming monitor that sits in the premium curved display category. It's a 3440 x 1440 IPS panel with a 1900R curve, 120Hz refresh rate, and native G-Sync. We're looking at a renewed unit here, which means it was inspected and repackaged by Amazon Renewed and comes with a 90-day warranty. At around $635 USD, it's a lot of screen for the money if you can live with the renewed caveats.

People searching for this monitor usually want to know if it's still worth buying in a world full of OLEDs and 240Hz panels. The short answer is yes, for the right person. The AW3420DW delivers a genuinely immersive 21:9 experience with colors that punch well above what you'd expect from an IPS panel of this generation. It's not the newest thing on the block, but it's far from obsolete.

We've seen this monitor rank in the 95th percentile for social proof in our database, which tells you people really do love it. The 4.6-star rating across 1,552 reviews backs that up. It's a crowd favorite, and that reputation didn't come from nowhere.

Skip the AW3420DW if you're a competitive esports player who needs 240Hz or higher refresh rates. The 120Hz ceiling will feel limiting in fast-paced shooters. AMD GPU owners should also look elsewhere since the G-Sync module only works with NVIDIA cards. If you want real HDR performance with high peak brightness, this isn't the panel for you. And if you're not comfortable with renewed products, the 90-day warranty and potential for repaired cables or wrong color shipments might be a dealbreaker. In those cases, consider a new LG UltraGear ultrawide or a 27-inch OLED from ASUS or MSI instead.

Should you buy the Alienware AW3420DW? If you want a 34-inch curved ultrawide with excellent color and native G-Sync, and you're comfortable with a renewed unit, then yes. This monitor delivers a genuinely immersive experience that's hard to match at $635. The 120Hz ceiling is the main compromise, but for RPGs, strategy games, and cinematic titles, that's more than enough.

If you're a competitive esports player who needs 240Hz or higher, or if you want OLED contrast and HDR brightness, look elsewhere. The AW3420DW is a fantastic ultrawide for the right buyer, but it's not a do-everything panel. For immersive single-player gaming and productivity work, it's still one of the best values in the curved ultrawide category.
