The Dell S3422DWG is a very good 34 inch 1440p ultrawide monitor with a VA panel. It has good contrast and amazing 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 an excellent response time at the max refresh rate, fantastic 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.
The Dell S3422DWG is a very good monitor overall. It's a great gaming monitor with low input lag and a fast 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.
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 and decent accuracy out of the box, but there's no sRGB clamp.
The Dell S3422DWG is a great gaming monitor. It has low input lag, an excellent 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 amazing 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.
The Dell S3422DWG is a very 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 amazing 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.
The Dell S3422DWG is a very 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.
The Dell S3422DWG is a good monitor for HDR gaming. It has low input lag and an excellent response time, and it supports FreeSync for a nearly tear-free gaming experience. It has good contrast and amazing black uniformity, and it has good peak brightness in HDR, so small highlights stand out a bit. There's no local dimming feature, though, so it can't deliver a true HDR experience.
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.
The stand has a small overall footprint, so you can still place small objects in front of the monitor. It supports the monitor well but feels a bit cheap compared to most older Dell monitors we've tested and 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.
Due to the curvature of the screen, it's a bit thicker than most similar displays.
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.
As expected from a VA panel, the Dell S3422DWG has good native contrast, so blacks look good in a dark room. Contrast can vary between individual units, but these results are similar to most other VA monitors we've tested. There's no local dimming feature to boost contrast.
The Dell S3422DWG doesn't have a local dimming feature. The video is for reference only, so you can see how the backlight on this display performs and compare it to a similar product with local dimming.
The Dell S3422DWG has great 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.
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.
We measured the HDR peak brightness in the 'DisplayHDR 400' Picture Mode and Brightness set to max. The peak brightness can change depending on which mode you're using.
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.
The Dell S3422DWG has a sub-par vertical viewing angle. As you move off-center, black levels rise and gamma shifts, causing the image to lose contrast and appear washed out. Colors wash out quickly but retain their hue even at a wide angle.
The Dell S3422DWG has excellent gray uniformity. The sides of the screen are a bit darker than the center, and there's a dark horizontal band running across the center of the screen, but it's not too noticeable. There's very little dirty screen effect. Near-black scenes look even better, with no significant issues. Gray uniformity can vary between units, but it's rare for modern monitors to have any issues like this.
The Dell S3422DWG has amazing black uniformity. There's almost no clouding throughout the screen, and no blooming at all around the test cross. Black uniformity can vary between units.
The Dell S3422DWG that we bought has decent accuracy out of the box, but this can vary between units. The white balance is decent, but brighter scenes are a bit off, and the color temperature is a bit cool. Gamma doesn't follow the sRGB target curve, and most scenes are too bright. Unfortunately, most colors are oversaturated, and there's no sRGB clamp.
After calibration, the Dell S3422DWG has much better accuracy. Gamma is very close to the sRGB curve, and white balance is nearly perfect. Colors aren't oversaturated anymore, and there are no noticeable issues with any color. The color temperature is very close to our 6500K target.
You can download our ICC profile calibration here. This is provided for reference only and shouldn't be used, as the calibration values vary per individual unit due to manufacturing tolerances, even for the same model.
The Dell S3422DWG has a superb SDR color gamut. It can display pretty much the entire sRGB color space used by most desktop and web content. Coverage of the wider Adobe RGB color space is great, but might be a bit too low for some content creators.
This monitor has fantastic SDR color volume. The Dell S3422DWG can display most of the sRGB color space at all luminance levels. Despite the relatively high contrast ratio, it still can't display saturated colors at low luminance levels though.
The Dell S3422DWG has a good HDR color gamut, and it can display a wide color gamut. It has excellent coverage of the DCI P3 color space used by most current HDR content. Coverage of the wider Rec. 2020 color space is mediocre, though, so it's not very future proof.
This monitor has decent color volume in HDR. It's mainly limited by the incomplete color gamut, even in the DCI P3 color space.
The Dell S3422DWG shows slight signs of temporary image retention, but it disappears quickly. This can vary between individual units.
The Dell S3422DWG has incredible gradient handling. There's a bit of banding in darker shades, but it's not really noticeable with most content.
There are no noticeable signs of color bleed on our Dell S3422DWG. This can vary between individual units, but it's rarely noticeable.
This monitor has good reflection handling. The Dell S3422DWG has a matte finish, which diffuses direct reflections, reducing their intensity.
The Dell S3422DWG has good text clarity, thanks to the relatively high pixel density. We recommend running the ClearType wizard if you're on a Windows PC, otherwise there are some issues with diagonal or curved lines, as shown in the bottom photo.
|Response Time Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The response time at the max refresh rate is excellent. 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 black smear in some content.
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.
|Response Time Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The Dell S3422DWG has a great 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 we recommend changing the overdrive setting if your refresh rate changes.
The Dell S3422DWG has a completely flicker-free backlight, which is great.
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 scoring is based only on the refresh rate range supported by the BFI feature, not how well it works.
The Dell S3422AWG has a fast refresh rate, and it supports FreeSync variable refresh rate (VRR) technology. It has a wide refresh rate range for VRR, ensuring a nearly-tear free gaming experience from an AMD graphics card.
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 shouldn't have any issues. If it drops below that, we noticed significant flickering that got worse as the frame rate decreased. We've also seen a few reports of a screen door effect in some games, but we didn't notice this issue on our unit.
The Dell S3422DWG has fantastic low input lag, resulting in a very responsive gaming experience. Enabling VRR increases the input lag a little bit, but it's not really noticeable.
Unfortunately, we couldn't measure the 10-bit HDR input lag because the highest refresh rate for 10-bit HDR over HDMI on this monitor is 60Hz, and we don't have the necessary tools to measure it at its max refresh rate over a DisplayPort connection. We don't expect HDR to increase the input lag.
The Dell S3422DWG has an excellent amount of screen space to work with. The pixel density is high, resulting in a sharp image and clear text.
There are two sets of inputs on the Dell S3422DWG. The main inputs are located on the back of the monitor and face down. There's a second set of connectors underneath the bottom bezel, near the Dell logo. That panel has two USB ports and a headphone jack, which is a nice convenience feature.
There's some confusion over the bandwidth of the DisplayPort connectors on the monitor, as Dell's website lists both 1.2 and 1.4. We checked the supported resolutions and confirmed that they must be 1.4 ports.
The Dell S3422DWG has a few additional features, including:
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.
There's a joystick control on the back for navigating the OSD. Four quick access buttons can be assigned to different options.
We tested the 34 inch Dell S3422DWG, which is part of Dell's S Series of gaming monitors. It's the only size available in an ultrawide format, but there are other models in Dell's S Series lineup, some of which are listed below. There's also a non-gaming variant of this model, known as the Dell S3422DW. It has a similar form factor, but a lower refresh rate and a completely different design.
|Model||Size||Native Resolution||Max Refresh rate||Panel Type||Curve|
|S2522HG||24.5"||1920 x 1080||240Hz||IPS||No|
|S2722DGM||27"||2560 x 1440||165Hz||VA||1500R|
|S3222DGM||32"||2560 x 1440||165Hz||VA||1800R|
|S3422DWG||34"||3440 x 1440||144Hz||VA||1800R|
|S3422DW||34"||3440 x 1440||100Hz||VA||1800R|
