This monitor was replaced by the Dell Alienware AW2723DF

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.

Compared To Other Monitors

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.

Samsung Odyssey G7 C32G75T

The Samsung Odyssey G7 C32G75T and the Dell Alienware AW2721D are both great monitors that use different panel types, each with advantages and disadvantages. The Samsung uses a VA panel that can produce deep blacks thanks to its high contrast ratio. The Dell uses an IPS panel that has great viewing angles at the expense of contrast ratio. Both have a low input lag and exceptional response times, although the Samsung includes a black frame insertion feature. The Dell gets much brighter in HDR, but it's limited by its low contrast ratio. The biggest difference is that the Samsung is a curved monitor while the Dell isn't.

ASUS ROG Swift PG279QM

The Dell Alienware AW2721D and the ASUS ROG Swift PG279QM are very similar, each with strengths and weaknesses. The Dell has a better vertical viewing angle and better ergonomics, and it's brighter in both SDR and HDR. The ASUS, on the other hand, has better reflection handling and a wider color gamut, and it has built-in speakers.

Dell Alienware AW2723DF

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.

LG 27GP850-B/27GP83B-B

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 better reflection handling, a better response time, and an optional black frame insertion feature to improve motion handling.

Dell Alienware AW2521HF

The Dell Alienware AW2721D is better overall than the Dell Alienware AW2521HF, although they have different sizes and resolutions. The AW2721D is slightly bigger at 27 inches with a 1440p resolution, while the AW2521HF is a 25 inch 1080p monitor. The AW2521HF has a slightly better response time with less overshoot and much better reflection handling, but the AW2721D supports HDR, gets brighter, and has a wider color gamut.

ASUS ROG Swift PG279Q

The ASUS ROG Swift PG279Q and the Dell Alienware AW2721D are both 27 inch, 1440p gaming monitors with native G-SYNC support. Although the Dell has a higher refresh rate and lower input lag, casual gamers might not notice the difference. The Dell supports HDR, whereas the ASUS doesn't, and it also has more USB ports.

Acer Predator XB273U GXbmiipruzx

The Acer Predator XB273U GXbmiipruzx and the Dell Alienware AW2721D are both great monitors, but the Acer performs a little better overall, especially when it comes to gaming. The Acer has a higher overclockable refresh rate, as well as faster response times at both its max refresh rate and 60Hz. It also has a wider color gamut and better reflection handling, as well as a USB-C port with power delivery and DisplayPort Alt mode.

Gigabyte M27Q (rev. 1.0)

The Dell Alienware AW2721D and the Gigabyte M27Q (rev. 1.0) perform similarly overall. They're both great 27-inch 1440p gaming monitors, but the Dell feels noticeably better built and offers more adjustment options. The Dell also has a higher refresh rate, gets brighter in HDR, and has a faster response time, although there's less overshoot with the Gigabyte. That said, the Gigabyte may represent a better value to some people.

Samsung Odyssey G7 S28AG70

The Dell Alienware AW2721D and the Samsung Odyssey G5 S27AG50 are different types of gaming monitors. The Dell is meant for high-frame-rate gaming because it has a 240Hz refresh rate with a 1440p resolution, and it has native G-SYNC VRR support. The Dell has a faster response time, but there's also more overshoot, and motion handling is fantastic between each. The Samsung is meant for high-resolution gaming because it has a 4k resolution with FreeSync support and HDMI 2.1 inputs, making it a good choice for console gaming. The Dell gets brighter, but the Samsung has better reflection handling. Also, while they each have local dimming features, they both perform terribly.

HP OMEN 27c

The Dell Alienware AW2721D and the HP OMEN 27c are both great gaming monitors. They each have a 1440p resolution and a 240Hz refresh rate, but the Dell has native G-SYNC support while the HP has native FreeSync support. They also have different panel types; the Dell has an IPS panel with better viewing angles, and the HP's VA panel has a higher contrast. The Dell offers better picture quality, as it gets brighter, displays a wider range of colors, and has much better motion handling. It also has much better ergonomics. On the other hand, the HP has much better reflection handling, so intense glare isn't as distracting.

Dell S2721DGF

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.

Dell Alienware AW3821DW

The Dell Alienware AW2721D is a bit better for gaming than the Dell Alienware AW3821DW, mainly because the AW2721D has a higher 240Hz refresh rate. The AW2721D also has a quicker response time, even at 60Hz, which results in smoother motion, and it has better ergonomics as you can rotate it into portrait mode. However, the AW3821DW delivers a more immersive gaming experience thanks to its larger 38 inch screen, and it has a higher 3840x1600 resolution that delivers crisp images.

Gigabyte AORUS FI27Q-X

The Gigabyte AORUS FI27Q-X and the Dell Alienware AW2721D are both great overall monitors with similar features. They're each 27 inch, 1440p screens with a 240Hz refresh rate. The Gigabyte has native FreeSync support, G-SYNC compatibility, and it has a quicker response time. However, the Dell gets much brighter, especially in HDR, and it has native G-SYNC support, but FreeSync also works on it. Choosing one over the other can really depend on which graphics card you have.

Dell Alienware AW2521H

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.

LG 32GP850-B

The LG 32GP850-B and the Dell Alienware AW2721D are very similar overall, but the LG is better for gaming. The LG has an optional black frame insertion feature, better reflection handling, and a better response time. On the other hand, the Dell has better ergonomics, a slightly faster refresh rate, and better vertical viewing angles. Another factor to consider is the supported variable refresh rate formats. The Dell is a native G-SYNC model, supporting variable overdrive when connected to an NVIDIA graphics card, while the LG natively supports FreeSync.

Razer Raptor 27 165Hz

The Razer Raptor 27 165Hz and the Dell Alienware AW2721D are great 1440p gaming monitors with some differences. The Dell has a 240Hz panel with native G-SYNC support, and it has a much quicker response time, while the Razer is a 165Hz monitor with FreeSync support. The Dell gets much brighter, but the Razer has better reflection handling. The Dell has better ergonomics, making it easier to place in an ideal viewing position. The Razer has a USB-C input, which the Dell doesn't have, meaning that you can connect compatible USB-C devices with it.

Dell G2722HS

The Dell Alienware AW2721D is a different gaming monitor than the Dell G2722HS. The AW2721D has a high 240Hz refresh rate with a 1440p resolution and native G-SYNC support, while the G2722HS is an entry-level model with a 165Hz refresh, 1080p resolution, and native FreeSync support. Because of these differences, the AW2721D is much better overall as it has much better ergonomics, gets brighter, and supports HDR, which the G2722HS doesn't. However, the G2722HS has a quicker response time at 60Hz, so motion looks smoother with lower-frame-rate games.

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.

Edge

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.

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.

The response time at 60Hz is excellent, although not as fast as at the max refresh rate. The best overdrive setting with the least amount of overshoot is the 'Fast' setting. If you play low-frame-rate games and care about the 60Hz response time, then look into the Dell G2722HS.

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.
