About this deal

After messing with the color calibration and the built in settings I finally found settings that seriously bring out some serious clarity for the AW2521hf monitor. I've had this monitor for about 6 months now and honestly I feel as if I just discovered a new one. I used the built in settings and also used the nvidia control panel color settings for this so I apologize to anyone with an AMD card. Warmer than factory defaults, but far from ‘Warm’ on our unit with a high colour temperature and cool tint to the image. Where the TN panel shines, is its low response times and input lag. However, in this case (surprisingly enough), the IPS panel of the AW2521HF actually performs on an almost equal level to the TN panel of the AW2518HF.

Note that there is always some disparity between how emissive objects (monitor) and non-emissive objects (printed sheet) appear. The representation of shades in this image depends on the camera and your own screen, it’s not designed to show exactly how the shades appear in person. It still helps demonstrate some of the relative differences between the original intended sRGB shade and what the monitor outputs, however. Full profiling and appropriate colour management on the application would provide a tighter match, our intention here is to show what can be expected in a non colour-managed environment. Also of equal caliber are the peak brightness levels that these Alienware variants are capable of. Though neither of the two support HDR, both exhibit an impressively high SDR peak brightness level that exceed 400 nits. According to Tom’s Hardware the AW2518HF was able to reach a peak brightness level of 418.6 cd/m 2, while according to Rtings.com the AW2521HF exhibited an SDR Real Scene peak brightness level of 406 cd/m 2.

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) The price should be the same for both models, though it can vary depending on your region. Price & Similar Monitors That said, when compared with a good 144Hz display, the AW2521H is a minor upgrade designed for a very specific type of player: seriously competitive esports enthusiasts. The 360Hz motion is a noticeable jump from 144Hz and 240Hz, however slight – I ran an ABX test myself – but for most people, it's not worth the few hundred extra dollars it currently costs. IPS glow’ eats away at detail, particularly near bottom corners. Screen surface imparts a bit of graininess to lighter content This is also why TN monitors were almost exclusively used by competitive gamers and tournament organizers alike, as these panels are known to display the least amount of input lag, and have some of the fastest response times when compared to their early IPS or VA counterparts. However, as monitor technology has advanced, these shortcomings have been expiated to a considerable degree with the release of fast IPS, SS IPS, and SVA panels.

Decided to post this here since I struggled with how flat the colors and contrast looked. Hopefully anyone else experiencing this issue can use these settings and achieve similar results. Let me know if you try these and if you love or hate them. Also similar are their power demands, with the AW2518HF consuming 26 W on average (73 W maximum), while the AW2521HF fares slightly better at a 24 W average power consumption (72 W maximum); meaning an estimated 55.52 kWh of annual energy expenditure. The Alienware AW2521HF has an exceptionally low input lag of only ~2ms, which guarantees that you won’t be able to notice or feel any delays between your actions and the result on the screen.

There’s also the Dell Alienware AW2521HFL model with a different color scheme (‘L’ stands for ‘Lunar Light’ whereas the AW2521HF model has the ‘Dark Side of the Moon’ theme). 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. The bottom line; strong responsiveness and colour performance from a stylish and well-priced monitor. The monitor can get very bright, even for well-lit rooms, and you’ll want to reduce its brightness from the maximum. The variable refresh rate range is 48-240Hz, but LFC (Low Framerate Compensation) is supported meaning that below 48FPS, the refresh rate will be multiplied (for instance, 47FPS x 5 -> 235Hz) for smoother performance.
