Should you want to dispense with the stand and use your own (or wall mount it) that’s possible, too, since the screen has VESA standard 100mm mounting points but it would be a shame to miss out on such a stylish stand. It can also only reach 81.1% of the cinema-focused DCI-P3 color space. This isn't particularly high, and can result in dull colors when watching movies. The image appears ‘rich and natural’ overall, with good variety. The gamma is slightly below target, brightening up some shades just a little, but the overall image balance is very respectable. The Alienware AW2521HFL offers 99% sRGB and around 82% DCI-P3 coverage so the screen is pleasantly vibrant with a balanced level of saturation. Its measured accuracy has a 1.56 delta average which is excellent for a gaming monitor and considerably better than the AW2521HF’s result. Do take note that color accuracy scores always vary between every unit due to manufacturing tolerances, explaining the massive difference between the two identical models. We created out own LBL setting as described below. This provides effective blue light reduction and can easily be assigned to a numbered ‘Game’ preset for easy activation and deactivation.

IPS glow’ eats away at detail, particularly near bottom corners. Screen surface imparts a bit of graininess to lighter content Since 1982, PCMag has tested and rated thousands of products to help you make better buying decisions. See how we test. All that being said, if gaming is where your priorities lie, then the AW2521HF is a great choice. It’s fast and responsive, and is compatible with both AMD FreeSync Premium and Nvidia’s G-Sync technologies for tear-free gaming, which is a sensible move if you own a card from one manufacturer and think you might switch allegiance sometime in the future. It's definitely better than trying to fiddle with its Custom Colour preset, if only because each of its three Gamer profiles give you exactly the same level of control over its dozens of colour options. They're not particularly user-friendly, all told, and Alienware could probably do with chopping a lot of them to make the onboard menu settings easier to understand. Whereas most gaming monitors just give you easy RGB bars to adjust up and down, the AW2521HFL splits them into Gain, Offset, Hue and Saturation, and it's not immediately obvious which settings do what if you don't already know what those individual terms actually mean. Then again, my attempts at calibrating the Gamer preset to try and improve things further didn't actually yield the results I wanted (everything actually got a little worse), so they're probably best left alone anyway. The Alienware AW2521HFL has three main display outputs: two HDMI 2.0 ports and one DisplayPort 1.2 output.Reasonable contrast, in-line with expectation, strong gamma consistency and a pleasing luminance adjustment range Warmer than factory defaults, but far from ‘Warm’ on our unit with a high colour temperature and cool tint to the image.

The average contrast ratio with only brightness adjusted was 1054:1, a hair above the specified 1000:1 and as expected for the panel. With our ‘Test Settings’ we recorded a perfectly respectable 1063:1. The highest contrast ratio recorded on the table was 1107:1, using ‘Custom Color’ with all colour channels at their neutral position of ‘100’. The lowest contrast ratio recorded was 831:1, following the significant adjustments made for our ‘Relaxing evening viewing’ settings. The maximum luminance recorded in this table was 427 cd/m², whilst the minimum white luminance recorded was 33 cd/m². This yielded a 394 cd/m² luminance adjustment range with a good bright maximum and dim minimum. On Battlefield V the monitor provided a very fluid experience, where the frame rate kept pace with the 240Hz refresh rate. Compared to at 60Hz, or indeed a 60Hz monitor, you’re getting up to 4 times as much visual information pumped out every second. And twice as much when compared to 120Hz or 1.67 times as much compared to 144Hz. This gives an excellent ‘connected feel’, which describes the precision and fluidity felt when interacting with your character and the game world. The very low signal delay of this model also aided the ‘connected feel’, but the very high frame and refresh rate combination also helped. The perceived blur due to eye movement was also greatly reduced, much as demonstrated with the pursuit photos earlier on. The improvement in ‘connected feel’ and reduction in perceived blur was still noticeable to us and would be to sensitive users going up from 144Hz to 240Hz. Although not nearly as pronounced or obvious as stepping up from 60Hz to 144Hz (or even 120Hz). The Alienware AW2521HFL is a FreeSync Premium gaming monitor, but its also compatible with Nvidia’s G-Sync Compatible mode. Its certification is delayed at this time, but it is pretty much guaranteed since the Alienware AW2521HF is already listed by Nvidia. Input lag sits at 3ms, so there is no need to worry about delays or de-synced instances. Thoughts on the Alienware AW2521HFL The high refresh rate and frame rate combination can be particularly attractive for competitive gamers, but also appreciated by fans of less competitive fast-paced action. The Dell Alienware AW2521HF (now designated AW2521HFA in UK and EU) aims to find a nice balance between speed and image quality, combining a 240Hz refresh rate with the superior colour quality of an IPS-type panel. Adaptive-Sync support is included, allowing AMD FreeSync Premium and Nvidia’s ‘G-SYNC Compatible Mode’ to be used. We put this monitor through its paces, seeing how it compares to the more common TN options such as the impressively responsive Acer XN253Q X. More importantly, though, the colour accuracy of AW2521HFL's IPS panel also leaves a lot to be desired compared to its AOC rival. Whereas my X-Rite DisplayPro i1 colour calibrator showed the AOC C27G2ZU was already showing a near perfect 99% of the sRGB colour gamut straight out of the box on maximum brightness, the AW2521HFL only returned a rather sub-par coverage score of 90.9% when I tested it on its default Standard preset. I'd normally expect an IPS panel to hit around 96% of the sRGB colour gamut, but this was more in line with what I'd expect from a good TN panel.The monitor produced most shades here quite faithfully, accounting for the natural differences related to emissive vs. non-emissive objects noted above. Some shades appear a touch oversaturated due primarily to the slight extension in the gamut, the most noticeable being dark lime green (18) which appeared a touch more ‘neon’. On models with a significantly wider gamut, this shade and candy apple red (14), to name but a few, tend to look significantly more ‘neon’ than they appear here. Candy apple red appeared with a bit of an orange-red tone due to extension in the red to green edge of the gamut. Some shades, such as cerulean (2) and lilac (8), appear somewhat undersaturated. Gamboge (23) verged too much on a mustard yellow without a suitably warm golden hue, too. Medium orange (3), Persian pink (6) and looked slightly undersaturated in person, but they appear much less saturated and overly bright in the image compared to how they actually looked on the monitor. The consistency is also very good in most cases, superior to VA models and far superior to TN models (references here). Aquamarine (4) is particularly good at highlighting this relative strength. Medium chocolate brown (24) is also good for highlighting colour consistency, which like Aquamarine is positioned at the extremities of the screen. Medium chocolate brown and some neighbouring shades appear a touch more saturated and warmer in tone on the AW2521HF when displayed at the bottom vs. top of the screen. But this is due more to uniformity on our sample than viewing angle behaviour. Although this won’t correct uniformity issues, profiling the monitor with your own colorimeter or spectrophotometer is always advised for best results if the strongest colour accuracy is desired. Strong colour consistency and slight extension beyond sRGB, giving a ‘rich and natural’ image without potentially overbearing saturation The monitor includes a range of ‘Preset Modes’; ‘Standard’, ‘FPS’, ‘MOBA/RTS’, ‘RPG’, ‘SPORTS’, ‘Game 1’, ‘Game 2’, ‘Game 3’, ‘ComfortView’, ‘Warm’, ‘Cool’ and ‘Custom Color’. The numbered ‘Game’ presets and ‘Custom Color’ are most flexible as they allow you to adjust the colour channels and saturation levels. The remaining presets make specific adjustments to those and can’t be manually altered. The numbered ‘Game’ presets can have unique ‘Brightness’ and ‘Contrast’ levels assigned to them as well, whereas this is set universally for the remaining presets. Many of the presets make further adjustments, such as ‘FPS’, ‘MOBA/RTS’, ‘RPG’ and ‘SPORTS’ adding a sharpness filter which can’t be disabled or counteracted effectively in the OSD aside from by selecting a different preset. These were briefly explored in the OSD video, but for the purposes of this table we’ll be looking at manual adjustments and settings we feel have more utility.

The Alienware AW2521HFL is an excellent monitor overall with better imaging results over the dark gray-colored Alienware AW2521HF. It fares considerably better in color accuracy and brightness with minimal tweaking, but the calibrated results are identical. The monitor’s agile pixel response time and FreeSync/G-Sync compatibility make it a compelling choice for competitive gamers. The Lagom text appeared a blended grey throughout, with a slight red hue to the striping of the text. There were no clear flashes of saturated red, orange or green or shifts between these with a bit of head movement. This indicates a low viewing angle dependency to the gamma curve of the monitor, typical for an IPS-type panel. Calibrating the monitor will yield a very low deltaE average of only 0.54 which is very close to the result found on the Alienware AW2521HF. However, not all have access to a colorimeter, so we recommend using the custom color preset and tweaking the screen to your liking instead. The added cost of the gadget will make the total cost of your upgrade even higher, so it’s not worth it. We also observed various episodes of the animated TV series Futurama. This further reinforces the idea of strong colour consistency, with large areas of individual shade. The monitor performed well here, without clear shifts in saturation or colour tone. Slight changes could be observed at the very edges for some shades, such as the purple of Leela’s hair gaining a bit of an extra red vs. blue hue to the purple – more pronounced if sitting close to the screen. Most shades appeared very consistent indeed, with any slight deviation due more to uniformity than any viewing angle related weakness. This contrasted starkly with competing TN models that would show an obvious ‘gradient’ of saturation vertically and VA models which show shifts from centre to bottom and sides. For a wide range of shades. The pastel shades of this movie were suitably varied and muted, whilst vibrant shades such as neon reds and greens appeared fairly eye-catching. Not to the extent seen on models with a more generous colour gamut, but enough to stand out and have the intended look overall.

The Quick and the Solid

On Shadow of the Tomb Raider things were also presented in a rich and natural way. The environments looked in-place, with good variety and some good earthy browns and rich green shades. Some of the deep greens weren’t as lush as they could be, nor were things like bright purple flowers, red painted artifacts and some of Lara’s ornate dresses as eye-catching as we’ve seen. But they were still closer to the ‘vibrant’ vs. ‘washed out’ end of the spectrum in our view. Lara’s skin also appeared much as it should, without the overly tanned appearance that a wider gamut would provide. The strong consistency was also very evident when considering Lara’s glowing and all-too-perfect complexion. Even the best VA performers show quite pronounced shifts in saturation for such pastel shades when they’re shown towards peripheral sections of the screen rather than centrally. TN models show obvious saturation shifts vertically. In this case appropriate richness and saturation was maintained throughout. Full HD resolution is quite limiting in some respects, stand reasonably deep which could be an issue if you have a shallow desk (VESA mounting is an option) A sensitive camera and a utility called SMTT 2.0 was used assess the latency of the Dell Alienware AW2521HF. Over 30 repeat readings were taken to help maximise accuracy. Using this method, we calculated 2.63ms (under 2/3rds of a frame at 240Hz) of input lag. At 60Hz we measured a slightly higher but still reasonable 6.47ms. This figure is influenced both by the element of input lag you ‘see’ (pixel responsiveness) and the element you ‘feel’ (signal delay). It indicates a very low signal delay at 240Hz which even sensitive users shouldn’t find bothersome. Note that we have no way to accurately measure input lag with Adaptive-Sync active in a variable refresh rate and frame rate environment.

As shown in the image above, the monitor uses the usual RGB (Red, Green and Blue) stripe subpixel layout. This is the default expected by modern operating systems such as Microsoft Windows and Apple’s MacOS. As a Windows user you don’t need to run through the ClearType wizard, although you may still wish to adjust this according to your preferences. As a Mac user there’s no need to worry about text fringing from non-standard subpixel layouts. The subpixel layout and arrangement is normal and we had no subpixel-related concerns related to sharpness or text clarity on this model.Extras: AMD Freesync Premium, Nvidia G-Sync Compatible, height-adjustable stand, 4x USB3 ports (one with power charging), RGB lighting The image below is a macro photograph taken on Notepad with ClearType disabled. The letters ‘PCM’ are typed out to help highlight any potential text rendering issues related to unusual subpixel structure, whilst the white space more clearly shows the actual subpixel layout alongside a rough indication of screen surface. This model uses a ‘regular’ (medium) matte anti-glare surface. Strong glare-handling is provided due to significant diffusion of ambient light. This diffusion also affects light emitted from the monitor, with a negative impact on the clarity and vibrancy potential of the screen. The screen surface has a bit of graininess to it when observing lighter shades, a very slightly ‘sandy’ look to it, if you like. It doesn’t show strong graininess or a heavily smeared appearance, however. The surface texture is quite similar if not a touch lighter than the surface texture used on most high refresh rate ~24” Full HD TN models. Dell claims the Alienware 25 can hit up to 99% of the sRGB color space. It comes close in our tests, but in Standard mode, the monitor only reaches 96.8% of the gamut, as shown in the sRGB color-space diagram below...
