The Dell S3422DWG is a 34-inch 1440p budget ultrawide gaming monitor with an 1800R curve. As a gaming-focused monitor, it has a 144Hz maximum refresh rate and FreeSync variable refresh rate (VRR) support to reduce screen tearing. It also has some added productivity features, like PIP and PBP modes, and a USB 3.2 hub with four USB-A ports, though it doesn't have USB-C.
Our Verdict
The Dell S3422DWG is decent for PC gaming. Its 144Hz refresh rate is decent enough for most gamers, but it isn't ideal for competitive gaming. It also has only okay response time as there's noticeable blur and smearing with fast-moving objects. It also has distracting VRR flicker with changing frame rates, particularly in dark scenes. That said, it has low input lag for a responsive feel, and its ultrawide format provides plenty of screen space to view more of your game at once. Although it has a good native contrast ratio and excellent black uniformity, it lacks a local dimming feature to further improve the picture quality in HDR.
- Low input lag.
- 144Hz refresh rate.
- Ultrawide format.
- Noticeable motion blur and smearing.
- No local dimming feature.
- Distracting VRR flicker with changing frame rates.
The Dell S3422DWG is okay for console gaming. It can't take full advantage of consoles as the PS5 and Xbox Series X|S don't support ultrawide gaming, and the monitor doesn't support HDMI 2.1 bandwidth either. That said, it still supports most signals from the consoles. It has low input lag for a responsive feel, but motion is blurry, and there's smearing with fast-moving objects.
- Good contrast.
- Low input lag.
- Noticeable motion blur and smearing.
- Can't take full advantage of consoles.
The Dell S3422DWG is a decent monitor for office use. It has good text clarity, and its 34-inch size is large enough to open multiple windows side-by-side. It has good brightness to fight some glare, but it has distracting reflections in a bright room. However, it has unremarkable ergonomics and narrow viewing angles, making sharing your screen with others difficult.
- Very good peak brightness in SDR.
- Superb SDR color gamut.
- Ultrawide format.
- Narrow viewing angles.
- Unremarkable ergonomics.
- No USB-C.
Distracting reflections in bright rooms.
The Dell S3422DWG is decent for content creation. Its 34-inch, 1440p screen creates a large workspace with good text clarity. It also has good contrast, ensuring that deep blacks are visible even if you're editing images in a darker room. However, its accuracy before calibration is disappointing, and it needs a full calibration for the most accurate image. It also has unremarkable ergonomics and narrow viewing angles, making sharing your screen with others difficult.
- Good contrast.
- Very good peak brightness in SDR.
- Superb SDR color gamut.
- Ultrawide format.
- Narrow viewing angles.
- Unremarkable ergonomics.
- Disappointing accuracy before calibration.
- No USB-C.
Distracting reflections in bright rooms.
The Dell S3422DWG has good brightness. It gets bright enough to fight some glare in a moderately-lit room, and while it gets bright in HDR, small highlights don't pop against the rest of the image.
- Very good peak brightness in SDR.
- Small highlights don't pop in HDR.
The Dell S3422DWG has an okay overall response time. It has okay motion handling across its VRR range, but it's worse at lower refresh rates, and there's noticeable blur and black smearing with fast-moving objects.
- Motion handling remains mostly consistent across VRR range.
- Noticeable motion blur and smearing.
The Dell S3422DWG is disappointing for HDR. Without a local dimming feature, it fails to improve the contrast ratio by making small highlights stand out against the rest of the image, but it still has a good native contrast ratio. It also has good HDR color volume but fails to display really bright and really dark colors.
- No local dimming feature.
- Small highlights don't pop in HDR.
The Dell S3422DWG has great picture quality in SDR. It has a good native contrast ratio that helps it display deep blacks in dark rooms, and there isn't much blooming around bright objects.
- Good contrast.
- Superb SDR color gamut.
- Excellent black uniformity.
The Dell S3422DWG has decent color accuracy. As it has disappointing accuracy before calibration, you need to calibrate it for the most accurate colors. However, if you do, it maintains that accurate image consistently across the entire screen thanks to its great gray uniformity.
- Great gray uniformity.
- Disappointing accuracy before calibration.

Popular Monitor Comparisons
The 34-inch Dell S3422DWG is a decent budget ultrawide gaming monitor with low input lag, but it has noticeable motion blur. Its large size provides an immersive experience, and its good contrast ensures it works well in darker rooms. It's fine if you want an ultrawide monitor with a VA panel for this high contrast. However, if you're looking for a slightly more expensive 34-inch ultrawide gaming monitor with a faster response time, better viewing angles, improved ergonomics, and USB-C support, consider the Gigabyte M34WQ.
For more options, check out our recommendations for the best ultrawide gaming monitors, the best 34-49-inch monitors, and the best gaming monitors.
The Dell S3422DWG is better than the Samsung Odyssey G55T C34G55T. The Dell has better ergonomics, slightly better viewing angles, and a much faster response time, despite the Samsung's higher refresh rate. The Samsung has better contrast, but the Dell has much better black uniformity. There's also a slight design difference, as the Samsung has a more pronounced curve, which might bother some people.
The LG 34GN850-B and the Dell S3422DWG are both ultrawide gaming monitors, but there are a few differences due to their panel types. The LG has an IPS panel with much better motion handling and an overclock feature for a slightly higher 160Hz refresh rate. The LG also delivers a more realistic image thanks to its better accuracy before calibration. On the other hand, the Dell gets brighter in HDR for a more vivid image, and it's also the better choice for dark room gaming as it delivers deeper blacks.
The Dell S3422DWG and the Gigabyte M34WQ use different panel technologies, each with strengths and weaknesses. The Dell uses a curved VA panel, so it's a better choice for a dark room, as it has better contrast. The Gigabyte is a flat IPS monitor, so the image remains accurate at an angle. The Gigabyte also has better ergonomics and a better selection of additional features.
The Dell S3422DWG and the HP OMEN 34c are similar ultrawide gaming monitors, but there are a few differences. While the HP has a slightly higher 165Hz refresh rate, the Dell has a quicker response time, leading to less motion blur, but each monitor has smearing with fast-moving objects. The Dell is also better to use with gaming consoles as it can downscale a 4k image, which the HP can't do. Lastly, the Dell has a few extra features, like a USB hub, making it the better choice if you need more USB ports to plug in your devices.
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.
