The Dell S3422DWG is a very good 34 inch 1440p ultrawide monitor with a VA panel. It has good contrast and great black uniformity, so it looks great in a dark room. It's not too shabby in a bright room, either, as it has good reflection handling and great peak brightness in SDR. It's mainly marketed as a gaming monitor. It delivers a great gaming experience with a good response time at the max refresh rate, excellent low input lag, and support for FreeSync variable refresh rate technology. Although it's not officially G-SYNC compatible, it's also possible to still use G-SYNC over DisplayPort, but unfortunately, it doesn't work properly if your frame rate drops below 60fps. Sadly, like most VA panels, the image degrades at an angle, so it's not the best for co-op gaming.

Our Verdict

7.8 Mixed Usage

The Dell S3422DWG is a very good monitor overall. It's a great gaming monitor with low input lag and a good response time. It's good for office use, but the image degrades at an angle, and it has limited ergonomics. It's very good for watching videos or media creators, with good contrast and a superb color gamut. Finally, it's a good monitor for gaming in HDR, but it's not bright enough for a true cinematic HDR experience, and it doesn't have a local dimming feature.

Pros
  • Good contrast.
  • Very good peak brightness in SDR.
  • Excellent low input lag.
Cons
  • Image appears washed out at an angle.
  • Stand can't swivel.
7.6 Office

The Dell S3422DWG is a good monitor for office use. It has excellent screen real estate, great for multitasking. It also has great connectivity, including a built-in USB hub, and it supports Picture-in-Picture and Picture-by-Picture, meaning that you can display two sources at once. It has good reflection handling and great peak brightness, so glare shouldn't be an issue. For work that requires accurate colors, it has a superb SDR color gamut, but unfortunately, it has disappointing accuracy out of the box, and there's no sRGB clamp, so colors are oversaturated.

Pros
  • Great gray uniformity.
  • Very good peak brightness in SDR.
  • Superb SDR color gamut.
  • Excellent low input lag.
Cons
  • Image appears washed out at an angle.
  • Stand can't swivel.
  • No USB-C.
  • Disappointing accuracy out of the box.
8.2 Gaming

The Dell S3422DWG is a great gaming monitor. It has low input lag, a good response time at the max refresh rate, and a few great gaming features, including support for FreeSync. The large, ultrawide screen delivers a more immersive gaming experience, and it looks great in a dark room, with a good contrast ratio and excellent black uniformity. Unfortunately, G-SYNC doesn't work properly if your frame rate drops below 60fps, and there can be some black smearing in dark scenes.

Pros
  • Good response time at the max refresh rate.
  • Excellent low input lag.
  • Fast refresh rate.
  • Ultrawide format delivers a more immersive gaming experience.
Cons
  • Black smearing in dark scenes.
  • G-SYNC compatible doesn't work properly below 60fps.
7.6 Media Consumption

The Dell S3422DWG is a good monitor for watching movies. The large size and 21:9 aspect ratio deliver a more cinematic viewing experience, with no black bars on most movies. It has good contrast and excellent black uniformity, great for watching movies at night. There are no issues using it during the day, as it has good reflection handling and great peak brightness. Unfortunately, the image washes out at an angle, so it's not the best for watching videos with a friend.

Pros
  • Great gray uniformity.
  • Good contrast.
  • Excellent low input lag.
  • Excellent black uniformity.
Cons
  • Image appears washed out at an angle.
  • Black smearing in dark scenes.
  • Disappointing accuracy out of the box.
7.7 Media Creation

The Dell S3422DWG is a good monitor for media creation. The large, high-resolution screen makes it easier to see more of your work at once. It has a superb SDR color gamut, but coverage of the Adobe RGB color space might be a bit too low for some content creators. Unfortunately, the image washes out at an angle and the stand can't swivel, so it's not the best if you often have to share your screen with someone else.

Pros
  • Great gray uniformity.
  • Good contrast.
  • Very good peak brightness in SDR.
  • Superb SDR color gamut.
Cons
  • Image appears washed out at an angle.
  • Stand can't swivel.
  • No sRGB clamp.
  • Disappointing accuracy out of the box.
7.2 HDR

The Dell S3422DWG delivers a decent HDR experience overall. It has a good contrast ratio and excellent black uniformity, resulting in deep, uniform blacks in a dark room, but there's no local dimming feature to improve contrast. It has good peak brightness in HDR, so small highlights in games stand out well, and it can display a wide color gamut. Finally, it has incredible gradient handling, with almost no noticeable banding in areas of similar color.

Pros
  • Good contrast.
  • Excellent black uniformity.
  • Good peak brightness in HDR.
Cons
  • No local dimming feature.

The Dell S3422DWG looks very similar to the other 2021 Dell gaming monitors, including the Dell S3222DGM. It has a fairly plain design that looks great in any setting. The stand is okay, with a slightly different design than previous generations. Instead of a full RGB backlight, there's a fixed-color blue ambient downlight feature on the bottom bezel.

Build Quality

The Dell S3422DWG has decent build quality. Like the other 2021 Dell monitors we've tested, including the Dell S2722DGM, it's entirely plastic. There's a bit of flex along the bottom bezel, but no bubbling or areas of significant concern. The stand is okay, but there's a bit of wobble due to the weight of the display.

The stand has an okay height adjustment and a fantastic tilt range, so it shouldn't be too difficult to place it in an ideal viewing position. It can't swivel, and due to the ultrawide, curved screen, it can't rotate to portrait orientation. The ergonomic adjustments feel smooth and are easy to adjust.

The back is pretty plain, with no bias-lighting or other advanced features. The inputs are hidden beneath the VESA mounting point, so they won't get in the way if you're planning on mounting it. There's a hole in the stand for basic cable management. Unfortunately, the VESA mounting points are indented in the back of the monitor, so if you're planning on mounting this monitor, you'll need a VESA bracket that's exactly 100x100mm, or extra-long spacers.

The Dell S3422DWG has very good peak brightness in SDR. There's no noticeable variation in peak brightness with different scenes, which is great. It's bright enough to overcome glare in most rooms. The minimum brightness level is very low, which is great if you're using it in a dark room and are sensitive to light.

These measurements were taken after calibration, in the 'Custom Color' Picture Mode, with the backlight at max. They're a bit lower than the advertised peak brightness for this monitor, but the peak brightness can change depending on which mode you're using.

The Dell S3422DWG has good peak brightness in HDR. It's not bright enough to deliver a true cinematic HDR experience when watching movies, but it's good enough for gaming. There's some variation in peak brightness in different scenes, but it's not noticeable. It significantly exceeds the peak brightness needed for its VESA DisplayHDR 400 certification. The brightness of the display tracks the EOTF well, as most scenes are displayed close to the correct brightness level. Unfortunately, there's an extremely sharp cutoff at the monitor's peak brightness, so fine details in bright areas are lost.

These measurements are in the 'DisplayHDR 400' Picture Mode, with Brightness set to max.

As expected for a VA panel, the Dell S3422DWG has a mediocre horizontal viewing angle. Gamma starts to shift immediately as you move off-center, causing the image to wash out. Colors wash out quickly but retain their hue even at a wide angle. The curved screen helps compensate for the degrading image, but our testing doesn't show the effects of this, as we measure viewing angles from the center of the screen.

Although it's not officially certified as G-SYNC Compatible, it's possible to enable G-SYNC when using this monitor with an NVIDIA graphics card, but only over DisplayPort. Unfortunately, there are some issues when using this monitor in G-SYNC compatible mode. As long as your frame rate stays above 60fps, you won't have any issues. If it drops below that, there's significant flickering that gets worse as the frame rate drops.

The response time at the max refresh rate is good. We recommend the 'Super Fast' Response Time setting, as it delivers the best overall results. There's a bit of overshoot with this mode, but it's not very noticeable. The 'Extreme' setting has a faster response time, so there's a shorter blur trail behind fast-moving objects, but there's significantly more overshoot, and there's a visible trail of inverse ghosting.

Like most monitors with a VA panel, the Dell S3422DWG has a slower response time in dark scenes, resulting in significant black smear in dark areas. This is especially distracting when scrolling the web with a dark background, or if you're using a dark user interface. It's not as noticeable when gaming.

Note: There's also a fourth response time setting, 'MPRT', but this isn't actually a response time setting, it just enables the black frame insertion feature. This setting is only available if the refresh rate is between 100Hz and 144Hz.

The Dell S3422DWG has an okay response time at 60Hz. We recommend the 'Fast' Response Time setting at 60Hz, as there's significantly more overshoot in the other modes. Unfortunately, this model doesn't have a variable overdrive setting, so you'll have to change the overdrive setting if your refresh rate changes for the best results.

The Dell S3422DWG has an optional backlight strobing feature that can be enabled by setting the Response Time to 'MPRT'. Enabling this feature locks the overdrive settings. It has a narrow range of refresh rates that support the feature, which is a bit disappointing. The backlight timing seems to be pretty good, so there's little crosstalk. Sadly, like most monitors, this feature can't be used at the same time as the variable refresh rate feature.

The Dell S3422DWG monitor supports most formats supported by the PS5. Since the PS5 doesn't support ultrawide aspect ratios, you have to set the Aspect Ratio setting to 'Auto Resize', otherwise the image will be stretched to fill the space. This results in black bars on either side, but the image is displayed correctly. Even though the native resolution of this monitor is below 4k, it can accept a 4k signal and downscale it to 1440p, resulting in a slightly sharper image than a native 1440p signal. Due to the bandwidth limits of the HDMI ports, though, it's limited to 60Hz if you decide to send a 4k signal. For a similar monitor with better PS5 compatibility, check out the Gigabyte M32UC instead.

For the most part, this monitor works perfectly with recent Macs. HDR works fine, and there are no issues with sleep/resume. VRR doesn't work properly though, as it flickers a lot when you're not gaming.

The Dell S3422DWG has a few additional features, including:

  • Timer: Displays a countdown timer on-screen.
  • FPS Counter: Displays the current frame rate the monitor is receiving from the source.
  • Dark Stabilizer: Adjusts gamma to make it easier to spot other players/enemies in shadows.
  • Display Alignment: Displays gridlines on the screen to help align multiple displays.
  • Downlight: Dell has added an ambient downlight on the bottom bezel. It's a fixed blue light that can't be changed, it can only be turned on or off.

It also supports both Picture-in-Picture and Picture-by-Picture, so you can display the image from two sources at once. Unfortunately, although there's a built-in USB hub, it there's no keyboard-video-mouse (KVM) switch, so you can't control both devices with a single keyboard and mouse without using third party software.
