The Dell Alienware AW3418DW is very good curved ultrawide IPS LCD monitor with a 3440x1440 resolution. It has very wide viewing angles so the sides of the screen remain accurate when viewed from up-close. The Alienware has a fast response time and very low input lag that will please most hardcore gamers and it also supports NVDIA's G-SYNC implementation of variable refresh rate so it can deliver smooth motion without tearing. Unfortunately, it can't produce deep, uniform blacks and it is not well suited for a dark room.

Compared To Other Monitors
The Dell Alienware AW3418DW is a good monitor for most usages and especially for gaming (see our recommendations for the best gaming monitors, the best ultrawide gaming monitors, the best 1440p gaming monitors, and the best curved gaming monitors).
The Dell Alienware AW3418DW is marginally better than the ASUS ROG PG348Q. The Alienware has a little faster refresh rate and produces a little less blur in fast-moving content. Also, the Alienware has lower input lag and responds slightly quicker to your actions giving you a small edge in gaming. Other than those minor differences, the two monitors are very similar.
The Dell Alienware AW3418DW is better than the Dell U3417W. The Alienware has a much lower input lag, less trail blur, and a faster refresh rate which help it deliver a great gaming experience.
The Dell Alienware AW3418DW is somewhat better than the LG 34UC79G-B. The Dell has a better resolution so you can see more detail on your screen and better reflection handling so you won't be bothered if your room has many lights. Its ergonomics make it also easier to position as you prefer. The LG has an optional black frame insertion feature that can clear blur and make the image crisper.
Unless you're looking for a more immersive gaming experience, the ASUS ROG Swift PG279Q is better than the Dell Alienware AW3418DW. The ASUS has a lower resolution screen, but a higher refresh rate, better ergonomics, and an optional black frame insertion feature. The AW3418DW, on the other hand, delivers a more immersive gaming experience, thanks to the 34" curve, 21:9 screen.
If you have more than one monitor next to each other and will be looking from the side, the Dell Alienware AW3418DW is a better choice as it has better viewing angles. But if you have a dark room and want HDR support, then the Samsung CHG70 is the way to go. The Samsung has better motion handling with a faster refresh rate and a black frame insertion feature to make the image crisper. The Alienware, on the other hand, is larger with better resolution and will display more details on its screen.
The Dell Alienware AW3418DW is a bit better overall than the Samsung C49HG90/CHG90. The AW3418DW has much better viewing angles, and it has a flicker-free backlight. The CHG90, on the other hand, has a much wider screen, which delivers a more immersive gaming experience and is better for multitasking. The CHG90 also supports HDR and has much better dark room performance.
The Dell Alienware AW3418DW is a bit better than the Acer Predator Z35P Bmiphz. The Acer has slightly better dark room performance, but the Dell looks better when viewed at an angle. The Dell also has a faster response time, so fast-moving objects have less blur trail behind them.
Overall, the Dell Alienware AW3418DW and the Dell U3818DW perform similarly, but the AW3418DW is better suited for gamers, whereas the U3818DW is better for office use. The AW3418DW has a faster refresh rate and better response time, as well as NVIDIA G-SYNC support.

The Alienware has an IPS panel with wider viewing angles, which is great for co-op gaming, while the S3220DGF has better dark room performance thanks to its VA panel. The Alienware offers you more space to work on thanks to its larger screen size and better resolution, but the S3220DGF supports HDR, so you can enjoy the latest HDR games.
Test Results
The stand supports the monitor well and there is little wobble. Its design blends with the overall futuristic design of this monitor.
The Dell Alienware AW3418DW has decent ergonomics. You can adjust the height, swivel left and right and tilt up and down, but there is no option to rotate. Nonetheless, the degrees of freedom should be enough to allow you to position it according to your preferences.
When looking the Dell Alienware AW3418DW from the back, the modern design with the abundance of straight lines and flat clear planes becomes apparent. The inputs are hidden and there is provision for cable management through the stand.
The borders of the Dell AW3418DW are thin. There is a vent that runs along the top border and serves for heat dissipation. The bezel is very thin and the panel starts at the edge of the border. The screen pixels, however, start after a small gap. It is nonetheless a very good monitor for side by side use.
The Dell Alienware AW3418DW is quite thick mainly due to the stand and the curve. Without the stand, this is a relatively thin monitor.
The build quality of the Alienware AW3418DW is excellent. There are no gaps or loose ends and the monitor feels sturdy.
The native contrast ratio of the Dell Alienware AW3418DW is sub-par. A low contrast ratio is expected in IPS panels and results in blacks that appear gray in the dark. The Alienware's native contrast ratio is slightly better than the Dell U3417W.
Local dimming is not supported. The video is for reference only.
Decent peak brightness for the Dell Alienware AW3418DW. The monitor is not suitable for a very bright room with a lot of glare. The good news is that the brightness remains constant regardless of the window size.
HDR is not supported.
Very good horizontal viewing angles for this monitor. The best we have measured so far along with the ASUS ROG PG348Q. This monitor will display the same image quality at very large side angles.
The vertical viewing angles of the Dell AW3418DW monitor are decent. The picture quality appears uniform at the bottom side of the screen, but if you place the monitor slightly higher than your eye level, you might notice some slight uniformity issues at the top side of the screen.
The gray uniformity of the Dell Alienware AW3418DW is good. There is some visible issues in the 50% gray image but this is mostly closer to the top edge and should not be distracting in normal use. There is no visible dirty screen effect. In the darker shades, the uniformity is excellent.
The Dell AW3418DW has poor black uniformity. There is clouding all over the image and there is visible backlight bleed in the lower two corners. This is very similar to Samsung CF791.
The 'Standard', 'Game 1', 'Game 2' and 'Game 3' Preset Modes were all nearly identical out of the box. The 'Game 1,2,3' modes allow you to set values for Dark Stabilizer and 'Red, Green, Blue, Cyan, Magenta, Yellow' saturation that are specific to that mode, allowing you to customize each 'Game' mode for a different use case or game.
The out of the box color accuracy of these modes is decent. White balance dE and color dE are both above our threshold of 3, and that means that most enthusiast users will notice some color inaccuracies. The color temperature is cold, and a bluish tint is apparent. Gamma averages 2.4, and doesn't track our target curve, and the image looks darker than what it should be.
After calibration, the color inaccuracies almost disappear. White balance dE and color dE are very low and it is almost impossible to spot inaccuracies. The color temperature is very close to our target of 6500 K, and gamma is almost perfectly tracking our target curve .
You can download our ICC profile calibration here. We don't recommend using this profile, as the calibration values vary per individual unit, even for the same model, due to manufacturing tolerances.
Excellent color gamut for the Dell AW3418DW. The monitor covers almost all of the sRGB space. However, the wider Adobe RGB color space used in professional printing or publishing applications is not adequately covered. If you are looking for a monitor that covers those needs check out the Acer Predator X27 and our recommendations for the best monitors for photo editing.
Excellent color volume coverage for this Dell AW3418DW. At various luminance values, the monitor can display a wide range of colors of the sRGB color space. However, in the darker shades, it is slightly limited by its low native contrast ratio. The Adobe RGB color volume coverage is confined by the limited Adobe RGB color space coverage and the low contrast ratio.
HDR is not supported.
HDR is not supported.
No image retention is visible, which is excellent. Even after 10 minutes of a high contrast static image, no remnants are visible.
Update 01/07/2019: The gradient score has been updated (7.2 -> 8.6), as it was scored incorrectly at the time of the review.
There's 8-bit banding in all colors; however, this should not be an issue for normal use.
When displaying large bands of a single color, no bleed can be seen and the colors appear uniform.
The Dell Alienware AW3418DW has good reflection handling. Very similar to the Dell U3417W. The curve helps diffuse point sources across the screen and thus reduce their intensity. The light-matte finish helps diffuse them even further, so this monitor will do well even in a fairly bright room.
Refresh Rate Tested: 120 Hz
Response Time 'Normal'
Response Time 'Fast'
Response Time 'Super Fast'
The Alienware is a fast monitor. The response time is low, and this means only a small blur will trail the image. Response Time 'Normal' is the best overdrive setting as 'Fast' and 'Super Fast' have unacceptable levels of overshoot causing image duplications. In the 'Super Fast' option, the overshoot from 0% to 20% is so much that it clips.
This monitor does not use PWM Dimming to lower the backlight and this is good as it makes motion look smoother.
On the other hand, this monitor lacks the option of introducing flicker to make the image crisper. This is a surprise as it supports G-SYNC and we would expect it to also support ULMB which is NVIDIA's implementation of black frame insertion.
Update 01/13/2022: We checked the FreeSync compatibility again, and changed the result to 'No' from 'Compatible'. Over HDMI, the refresh rate is limited to 50Hz, and FreeSync doesn't work at all. You can achieve 120Hz over a DisplayPort connection, but it's not considered FreeSync compatible in the Radeon Control Panel.
Excellent refresh rate. The Alienware AW3418DW supports the G-SYNC implementation of VRR. However, it is only supported through DisplayPort and not through HDMI that has a lower bandwidth. Over HDMI at 3440x1440 resolution, the monitor's maximum refresh rate is 50Hz, although other resolutions such as 1080p can run at 60Hz.
If you want a slightly higher refresh rate, Dell has a similar monitor with a 120Hz panel, the Dell Alienware AW3420DW.
Refresh Rate Tested: 120 Hz
The monitor has an excellent low input lag, which makes it very responsive. It is suitable for hardcore gaming as it reacts to your input almost instantaneously.
Over DisplayPort the only supported resolutions are (3440x1440, 1024x768, 800x600, 640x480), and only 3440x1440 is capable of refresh rates greater than 60 Hz. This isn't usually a problem though because most graphics cards will upscale lower resolutions to 3440x1440 without you even knowing.
This Dell Alienware AW3418DW has an excellent resolution for its size. You are able to easily multitask, and you will see every little detail your game has to offer.
One 3.5mm audio out is for headphones and has adjustable volume, while the other is a line out with fixed volume, which is useful when using external speakers.
This monitor does not have speakers or HDR10 support but has a few neat additional features:
- Frame Rate counter
- Timer
- Display Alignment overlay
This is useful for lining up multiple monitors. - Dark Stabilizer
This raises the gamma curve to brighten dark shades, which is useful in some games to make dark details more visible. Unlike similar features on other monitors, Dark Stabilizer does not raise the black level. - AlienFX Lighting
The monitor has several LED zones on its body. Each zone can be set to a different color, or all zones can be made to cycle through colors at the same time, using the 'Spectrum' option. The LEDs can also be controlled by AlienFX software on a PC when the USB hub is connected, which allows even more features such as reactive lighting in certain AlienFX supported games.
The controls are quite good. There are more buttons than most monitors, and it's easy to navigate the OSD which is designed really well. The buttons are easy to click and give good feedback.
However, we still prefer a joystick like the ones found on LG 34UC79G-B or the Acer Predator X27.
