The video below shows the monitor in action. The camera, processing done and your own screen all affect the output – so it doesn’t accurately represent what you’d see when viewing the monitor in person. It still provides useful visual demonstrations and explanations which help reinforce some of the key points raised in the written piece.
In case you just want to run your monitor at a fixed 240Hz refresh rate or with FreeSync/G-SYNC, the Dell AW2521HF will do just fine! 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. Another inherent advantage of IPS monitors is their superior color saturation and larger color gamut, which becomes apparent when they are compared to TN panels. This commonality proves to be true in this comparison as well, as we see the Dell AW2521HF outperform the AW2518HF in the Adobe RGB 1998 color gamut by a significant margin. That being said, the latter model does hold its own in regard to the sRGB color space, with Tom’s Hardware claiming it was able to reproduce 99.78% of the sRGB color spectrum, but only 68.42% of the Adobe RGB color space. On the other hand, when measuring the Dell AW2521HF, Rtings.com found it to be able to reproduce 97.7% of the sRGB xy color space (on CIE 1931 xy), and 75.21% of the Adobe RGB xy color spectrum (80.4% in lCtCp). Though its advantage is not of the magnitude one would expect for the typical panel properties, it still does give itself the edge over the Dell AW2518HF. To test the performance of monitors, I run a DisplayCal verification using an X-Rite i1Display Pro colorimeter, alongside a few by-eye tests using Lagom's LCD test patterns. The AW2521H is not an HDR or wide gamut monitor, instead hitting about 450 nits of maximum brightness and covering 92.8% of the sRGB color space. It is, however, extremely accurate within that sRGB space.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.
In some rare cases, dark pixels may not quite change into brighter shades in time with the refresh rate, which can result in visible ghosting behind fast-moving objects when dark pixels are predominant in the picture (dark scenes). An obvious cool (blue) almost icy-looking tint due to very high colour temperature. Some shades brightened up just slightly due to gamma handling, but not by a huge amount. Strong consistency due to IPS-type panel, without the perceived gamma and saturation shifts associated with TN or VA panels.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. The answer is almost certainly no -- it's not repairable. Dell doesn't repair monitors. If they fail, they're replaced. But not for a fall, that is not part of the Dell monitor warranty. And very few if any repair shops will undertake a monitor repair. Beyond the unavailability of screens, monitors are generally not designed to be disassembled for repair purposes - it's very common for screens to be fixed in place with adhesive. Further, the screen is a majority of the cost of the monitor -- it's not an economic proposition to repair these, even if parts are available. 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. The bottom line; strong responsiveness and colour performance from a stylish and well-priced monitor. However, since you’d need a wider color gamut and a much higher contrast ratio and brightness for a noteworthy HDR picture quality (none of which is offered by the other 1080p 240Hz IPS models), you’re not losing anything important here.
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). Reasonable contrast, in-line with expectation, strong gamma consistency and a pleasing luminance adjustment rangeThe Dell Alienware AW2521HF is yet another 1080p 240Hz IPS gaming monitor with a fast 1ms response time speed and AMD FreeSync (certified as ‘G-SYNC Compatible’).
