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.

The S2719DGF, on the other hand, has a higher refresh rate, better ergonomics, and a faster response time, making it a better choice for gaming.
The LG 34GK950F-B is a bit better than the Dell Alienware AW3418DW for most uses. The 34GK950F supports HDR, and it has an optional black frame insertion feature for clearer motion. The LG supports FreeSync variable refresh rate technology and has a faster refresh rate. The AW3418DW, on the other hand, has native G-SYNC support, great if you want to get the most from your NVIDIA graphics card.
The Dell Alienware AW3418DW and the Dell S3220DGF have different panel types, each with advantages and disadvantages. 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.
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 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 '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.
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:
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.
