The Dell Alienware AW2721D is an impressive 1440p gaming monitor. It has a 240Hz maximum refresh rate, an exceptional response time that results in minimal motion blur, and an incredibly low input lag that makes gaming feel responsive. It also has native G-SYNC support and is compatible with FreeSync to reduce screen tearing. It uses an IPS panel with wide viewing angles, but that comes at the expense of a lower contrast ratio, so blacks look more like gray when viewed in the dark. There's a local dimming feature to improve black levels, but it's not very effective. While it supports HDR and gets fairly bright for HDR content, its low contrast ratio means that the HDR experience is only decent. On the plus side, it gets bright enough to use in well-lit rooms, although it has mediocre reflection handling, so you may have issues with glare if you place it in front of bright lights.
We buy and test more than 30 monitors each year, with units that we buy completely on our own, without any 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 and custom tools to measure various aspects with objective data-based results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance against the competition, and whether or not it's easy to find.

Popular Monitor Comparisons
The Dell Alienware AW2721D is an impressive and versatile gaming monitor that's well-suited for a variety of uses. It has one of the widest color gamuts and one of the highest brightness in HDR among the gaming monitors we've tested, and it has better build quality than some of its direct competitors, like the ASUS ROG Swift PG279QM. For more options, check out our recommendations for the best gaming monitors, the best 1440p gaming monitors, and the best monitors.
The Dell Alienware AW2723DF is the replacement for the Dell Alienware AW2721D, and there are a few differences. The main difference is that the AW2723DF has native FreeSync support and G-SYNC compatibility instead of the native G-SYNC support on the AW2721D. This doesn't make much of a difference unless you have an NVIDIA graphics card, in which case, the AW2721D can take full advantage of it. Other than that, the AW2723DF has an overclockable 280Hz refresh rate and better motion handling, especially at lower refresh rates.
The Dell Alienware AW2721D and the Dell S2721DGF are both great gaming monitors with similar performance. That said, the AW2721D has a higher max refresh rate and slightly better picture quality overall. They have similar response times, although the S2721DGF experiences less overshoot. The S2721DGF has much better reflection handling and better ergonomics, but the AW2721D feels better built, gets significantly brighter in SDR and HDR, and has much better accuracy out-of-the-box, although this can vary between units. The S2721DGF may represent a better value to some people.
The Dell Alienware AW2721D and the Dell Alienware AW2521H are both great monitors that perform similarly in many ways, but they have different resolutions and sizes. The AW2521H is one of the rare monitors with a 360Hz max refresh rate, while the AW2721D has a max refresh rate of 240Hz, but the difference likely won't be noticeable to most gamers. That said, the AW2521H has a slightly better response time with less overshoot and better reflection handling. On the other hand, the AW2721D has a better color gamut and brightness for HDR, and it feels more well-built.
The Dell Alienware AW2721D and the LG 27GP850-B/27GP83B-B offer similar performance all-around, but there are some differences between them, so which one is better depends on your needs. The Dell has much better ergonomics, so it's easier to place in an ideal viewing position, and it seems to have much better build quality. If those don't matter to you, the LG has a better response time and an optional black frame insertion feature to improve motion handling.
Test Results
The Dell AW2721D has a sleek, gamer-oriented design, similar to previous Alienware monitors. It's mostly white with black accents and has thin borders. It also has four RGB lighting zones, including the downlight beneath the panel, the power button, the Alienware logo on the back, and the stand. It's heftier than similar-looking models like the Dell Alienware AW2720HF due to the more premium materials used in the stand.
The Dell AW2721D feels very well-built. It's sturdy. There's very little flex in the plastic, and the monitor feels stable no matter how you adjust it. It feels a bit more solid than other Alienware monitors too, but not enough to be a significant difference.
The Dell AW2721D has great ergonomics. The swivel range is a bit limited, but it allows for a lot of height and tilt adjustments. It can also rotate into portrait mode in both directions. The back of the monitor is made of plastic with an Alienware logo in the top right corner that lights up. There's a cutout in the stand for cable management.
The stand supports the monitor well, with very little wobble. It's capped in plastic, but most of the structure is metal, so it feels heavier and sturdier than previous Alienware monitors.
There are four buttons and a joystick located on the back of the right side of the monitor. These are used to navigate the on-screen display.

The Dell AW2721D has a passable contrast ratio, which is typical for an IPS panel. Blacks look more like gray when viewed in the dark. Note that the contrast ratio can vary between units.
The Dell AW2721D includes an edge-lit local dimming feature, but it's not especially effective. There are quite a few dimming zones, so there's not as much blooming as other edge-lit monitors, but there's still blooming along the whole height of the screen, and transitions between zones are fairly noticeable. There are also noticeable differences in uniformity when the vertical zones are lit up. That said, these issues are less noticeable with real content.
Note: While we've received reports that some people experience better local dimming on Mode 0, we chose to test local dimming using Mode 1 because it was the brightest and offered the best compromise between increased contrast and transition visibility. That said, we don't expect using a different local dimming mode to significantly affect the score.
The Dell Alienware AW2721D has excellent SDR peak brightness, higher than the advertised 450 cd/m2, so you shouldn't have issues using the monitor in well-lit rooms. With local dimming disabled, the brightness is more consistent, and it gets up to 575 cd/m2 in the sustained 100% window, which is significantly brighter than what you get with local dimming enabled.
We measured the SDR brightness after calibration in the 'Custom' Picture Mode, with Brightness set to max, and local dimming (Variable Backlight) set to 'Mode 1'.
The HDR peak brightness is good. Small highlights are significantly brighter than in SDR, reaching well above the advertised 600 cd/m2.
We measured HDR brightness in the 'Gamer 1' Picture Mode with Smart HDR enabled, Brightness set to max, and local dimming (Variable Backlight) set to 'Mode 1'.
The Dell AW2721D has good horizontal viewing angles. The image remains mostly accurate when viewed from the sides, so it should be fine for sharing content or co-op gaming.
The Dell AW2721D has impressive vertical viewing angles, which is great if you're sitting up close or have the monitor raised. There's some slight color washout at extreme angles, but for the most part, colors and black levels remain accurate.
The Dell AW2721D has excellent gray uniformity, although this can vary between units. The sides and bottom are slightly darker, but there's almost no dirty screen effect, and dark scenes look even more uniform.
Black uniformity on the Dell AW2721D is bad, although this can vary between units. There's noticeable backlight bleed in the corners and edges of the screen. Local dimming makes clouding look more prominent in sections that are lit up.
The Dell AW2721D has great out-of-the-box color accuracy. There are slight inaccuracies in most colors and shades of gray, but they're hard to notice. For the most part, gamma doesn't follow the curve, so most scenes appear brighter than they should. The color temperature is a bit cooler than our 6500k target, giving the image a blue-ish tint. Note that accuracy may vary between units.
After calibration, accuracy is incredible. Any remaining accuracies shouldn't be noticeable without the help of a colorimeter. Gamma follows the curve closely for the most part, and the color temperature is much closer to the target.
The Dell AW2721D has a remarkable SDR color gamut. It has nearly perfect coverage of the commonly used sRGB color space and great coverage of the Adobe RGB color space used by professional content creators.
SDR color volume is exceptional. Thanks to its remarkable color gamut and high peak brightness, it displays colors in a wide range of luminance levels. Unfortunately, its mediocre contrast ratio means it struggles to display dark, saturated colors.
The Dell AW2721D has a great HDR color gamut. It has amazing coverage of the more common DCI P3 color space, but its coverage of the wider Rec. 2020 is only decent.
The HDR color volume is great. It displays bright colors well thanks to its good HDR peak brightness, but it can't display darker colors due to its low contrast ratio.
The Dell AW2721D has mediocre reflection handling, worse than the ASUS ROG Swift PG279QM. It uses a matte coating that doesn't adequately diffuse indirect light, so reflections may be distracting in bright rooms. If you're looking for something with better reflection handling, then look into the HP OMEN 27c.
Text clarity is good. With ClearType enabled (top photo), diagonal lines look sharper, as seen in the R and the N, but straight lines aren't as bold, like in the T or I.
Gradient handling is fantastic. There's some very fine banding in darker shades, but it's hardly noticeable.
The Dell AW2721D has an exceptional 240Hz refresh rate with a wide VRR range. It has native G-SYNC support and is FreeSync compatible, but FreeSync only works over a DisplayPort connection. Unfortunately, you can only get up to 144Hz with 10-bit color at native resolution. You can get higher frame rates in 10-bit if you lower your resolution or by going down to chroma 4:2:2. If you don't need the native G-SYNC support and prefer something with native FreeSync, then check out this monitor's replacement, the Dell Alienware AW2723DF.

There are no issues using this monitor with a recent M1 MacBook Pro. HDR works perfectly. The variable refresh rate feature works well, but there's a bit of flickering at low refresh rates, and there are no issues when putting the computer to sleep or closing the lid. It wakes up quickly, and windows return to their original position.
The Dell AW2721D has a few extra features, including:
- RGB Lighting: RGB lighting zones on the back of the monitor, the stand, the downlight beneath the panel, and the power button. These can be customized through the AlienFX software.
- Display Alignment: Helps with alignment in a multi-monitor setup.
- Timer: Displays a timer onscreen.
