237fps) instead, avoiding any VSync latency penalty at frame rates near the ceiling of operation or tearing from frame rates rising above the refresh rate. The new generation TN panels such as the Acer XN253Q X dont show any noticeable weaknesses in terms of powdery trailing and offer impressively rapid pixel responses across the board. The following observations were made. 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. 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 monitor didnt provide excellent depth and atmosphere here due to the static contrast and IPS glow limiting things in that respect. Interlace pattern artifacts The monitor can also be set to 120Hz although not documented in this testing, results were very much comparable to 144Hz. Custom Color 2.1 7287K As factory defaults but somewhat warmer with a slight green tint and slightly higher brightness. As an Amazon Associate I earn from qualifying purchases made using the below link. The image below shows a printed reference sheet of 24 sRGB shades, included as part of the Datacolor SpyderCHECKR 24 package. The monitor produced most shades here quite faithfully, accounting for the natural differences related to emissive vs. non-emissive objects noted above. Slight deviation from preferred 2.2 gamma, without gamma settings in OSD. Unless youre frequently passing this boundary its not something youre likely to notice or care about, though. Youll see the same element on an Alienware gaming PC which we currently have in the lab. The screen is capable of better black luminance and saturation compared to other IPS panels, but it can still look grayish when viewing black images in a dark room. //]]> The Fast, Super Fast and Extreme settings are all rather similar here. 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. The screen surface has a bit of graininess to it when observing lighter shades, a very slightly sandy look to it, if you like. We also observed the contrast performance of Star Wars: The Rise of Skywalker. This was only observed during this test and is something weve seen on various monitors before. Less pronounced than youd see on TN or VA models. The best Alienware keyboards, mice, headsets, and more reviewed and analyzed. It still provides useful visual demonstrations and explanations which help reinforce some of the key points raised in the written piece. The table below shows these values as well as the percentage deviation between each quadrant and the brightest point measured. The contour map below shows these deviations graphically, with darker greys representing lower luminance and hence greater deviation from the brightest recorded point than lighter greys. Este artigo fornece informaes sobre os testes integrados de teste automtico (BIST, tambm chamado de diagnstico integrado ou BID) e testes de diagnstico de verificao automtica de recursos (STFC) disponveis nos monitores Dell. Most shades appeared very consistent indeed, with any slight deviation due more to uniformity than any viewing angle related weakness. Below you can see how things appear with refresh rate ramped up to 240Hz. Relaxing evening viewing You can adjust the color of this light in the on-screen display or turn it off entirely. Preset Mode= Game 1 The final point to note is that FreeSync only removes stuttering or juddering related to mismatches between frame rate and refresh rate. A sensitive camera and a utility called SMTT 2.0 was used assess the latency of the Dell Alienware AW2521HF. Fast flat panels used to rely on TN technology for their speed, but that is no more. The setting is listed as Wait for Vertical Refresh. The UFOs move across the screen from left to right at a frame rate matching the refresh rate of the display. Slight changes could be observed at the very edges for some shades, such as the purple of Leelas hair gaining a bit of an extra red vs. blue hue to the purple more pronounced if sitting close to the screen. It started to creep in a little bit even at the high double digit to very low triple digit frame rates. Input lag If a game ran at 34fps, for example, the refresh rate would be 68Hz to help keep tearing and stuttering at bay. 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. The colour temperature uniformity was good. Some users prefer to leave VSync enabled but use a frame rate limiter set a few frames below the maximum supported (e.g. window.__mirage2 = {petok:"zg2cYY5zq25POHOP6IsDfN8FBZJHLm773fg_fBtMlJU-1800-0"}; The final column includes a reference screen, the Acer XN253Q X which is a very fast 240Hz TN model with well-tuned pixel overdrive. This further reinforces the idea of strong colour consistency, with large areas of individual shade. So things didnt have a banded or blocky appearance as youd see if gamma was far too low. On TN models you have things looking far too masked higher up the screen due to high perceived gamma. It was free an obvious pink hue or saturation shifts that youd observe on models with weaker colour consistency. Our RX 580 is far from a powerhouse of a graphics card, so maintaining 240fps was very tricky. That means that if the game is running between 48fps and 240fps, the monitor will adjust its refresh rate to match. The brightest point recorded was quadrant 5 in the centre of the screen (168.2 cd/m). I've tried changing the response time from Extreme to Fast or Super Fast, but when I do that the blur get's even worse. Without FreeSync active and VSync disabled, youd get obvious tearing from the lack of synchronisation between frame and refresh rate. We prefer stronger RGB LEDs at the rear, producing a strong glow around the monitor that can help enhance perceived contrast. Response Time= Fast Wed describe the image as rich and natural, with a richness maintained throughout the screen thanks to the strong colour-consistency. 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 monitor offers fairly comprehensive sRGB coverage (99%), with a very small amount of under-coverage. With VSync on the frame rate will not be allowed to rise above 240fps, at which point VSync activates and imposes the usual associated latency penalty. Alienware's AW2521H is one such display, with a 1080p resolution, 360Hz refresh rate, and G-Sync in a stylish panel for esports enthusiasts. Some models are specifically validated as G-SYNC compatible, which means they have been specifically tested by Nvidia and pass specific quality checks. Around 1000:1 even following adjustments to our Test Settings. Gamboge (23) verged too much on a mustard yellow without a suitably warm golden hue, too. The remaining blocks were displayed appropriately with good steps up in brightness. This is exactly what the Dell Alienware AW2521HF delivered. Even if such dips were very slight, without FreeSync active and VSync enabled theyd cause obvious stuttering. $900 is pretty pricey for a 1080p display, but 360Hz is still the absolute fastest refresh rate you can buy, so you'll have to pay a premium if you're serious about competitive gaming. Compared to at 60Hz, or indeed a 60Hz monitor, youre getting up to 4 times as much visual information pumped out every second. Lightning-fast: Experience the best available in IPS Technology with native refresh rates of 240Hz. FreeSync: Yes; G Sync: No; . It indicates a very low signal delay at 240Hz which even sensitive users shouldnt find bothersome. A medium matte anti-glare screen surface is used, as explored shortly. The first couple of blocks blended into the background well, which is usual for a monitor tracking the 2.2 gamma curve correctly. Styling is minimalist but distinctly Alienware. Some appreciate the extra saturation and strong vibrancy of a more generous gamut, but we feel a decent balance is struck here with a bit of extra saturation and good richness throughout the screen. As the frame rate dropped we noticed an increase in overshoot. The ~1000:1 static contrast being somewhat limiting in that respect. FreeSync the technology and activating it The RTX 3080 is a . 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 dark desktop background highlights IPS glow, which creates an obvious bloom as viewing angles become steeper. This means that the connectivity layout doesnt have restrictions, so you get a full range of options with this model. The 240Hz refresh rate also allows even division of 24fps, 30fps and 60fps which reduces juddering for such content the lack of overshoot at 240Hz worked nicely as well. Brightness 100cd/m 2 - 18. //]]> When we say obvious, its very subjective sensitive users can certainly notice such things and it can be very nice indeed having them gone. You should then ensure that the first slider, Radeon FreeSync is set to Enabled as shown below. Alienware are touting . The default is Off, unless application specifies which means that VSync will only be active if you enable it within the game itself, if there is such an option. As such shades appear much as the developers intend, with a bit of extra saturation in places and a bit of extra vibrancy for some shades. The camera, processing done and your own screen all affect the output so it doesnt accurately represent what youd see when viewing the monitor in person. When measuring color accuracy, a deltaE value describes how closely a color matches its target point on the spectrum. Theres a customisable power indicator LED towards the bottom right, part of the AlienFX RGB lighting system. NY 10036. So things didnt have a banded or blocky appearance as youd see if gamma was far too low. Laras skin also appeared much as it should, without the overly tanned appearance that a wider gamut would provide. Together, the monitor certainly didnt provide a deep and atmospheric look to dark scenes and is more suited to viewing in a well-lit room. In the review of the Alienware AW2518H, it says that they calibrated the monitor to offer better colors but i can`t seem to find the exact settings that they used. Finally, note again that you can go to Game Enhance Mode in the Game section of the OSD to activate the Frame Rate feature. The stand is of high quality and offers a 5 inch height adjustment along with 20 degree swivel left and right, 5/21 degrees of tilt and a 90 degree portrait mode. Things arent quite up to the level of the TN reference, but there are no particularly pronounced weaknesses either. As an Amazon Associate I earn from qualifying purchases made using the below link. Its again important to note that individual unit vary when it comes to uniformity and that deviation beyond the measured points can be expected. The following observations were made from a normal viewing position, eyes ~70cm from the screen. IPS glow also featured, but appropriate room lighting took the edge off this. The brightest point recorded was quadrant 5 in the centre of the screen (168.2 cd/m). Remember, it's not just about that 360Hz refresh rate the response times are also a big improvement here, and I've used 144Hz monitors that felt much worse due to smeary motion. The Alienware AW2521HF performs as advertised for competitive gaming where speed and precision are necessary. Setting its overdrive to its Fast setting is a perfect choice so you can enjoy every frame clearly. Of course we are going to test this theory to see if the panel is really accurate. Our suggestions regarding use of VSync also apply, but youre using Nvidia Control Panel rather than AMD Radeon Software to control this. We also tested movie content, which was much more limited in frame rate (generally 24fps, 30fps or 60fps). 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. The UFOs move across the screen from left to right at a frame rate matching the refresh rate of the display. As frame rate dropped further, well below 200fps, the connected feel and perceived blur was noticeably impacted. Not to the extent seen on models with a more generous colour gamut, but enough to stand out and have the intended look overall. Turning up the Dark Stabilizer setting can help with this, though it will reduce the contrast ratio and make blacks look greyer which is rough, given that the IPS panel in this display already has a weak 1029:1 contrast ratio by my measurements. In this case, overshoot (inverse ghosting) including some colourful bright halo trailing due to aggressive pixel overdrive. All but the final pattern was distinct from the background, with the final pattern faintly visible although a bit fainter than it could be. According to user feedback the monitor runs at 120Hz on the PS5, as of the April 2021 update for the console. The Alienware AW2521HF sports a 25-inch IPS panel with a 1920 x 1080 resolution, 240Hz refresh rate, and 1ms response time. You also have to sacrifice resolution and screen size, which isn't ideal for more casual gamers with mixed preferences. But this is due more to uniformity on our sample than viewing angle behaviour. There was borderline significant deviation above the central region (DeltaE 3.0), with no significant deviation recorded elsewhere. Some models are specifically validated as G-SYNC compatible, which means they have been specifically tested by Nvidia and pass specific quality checks. Alienware claims 1ms grey-to-grey response time, but there are numerous ways to fudge this spec, so it's mostly meaningless real-world testing is far more revealing of a monitor's capabilities in this realm. The Super Fast setting just slightly reduces this, replacing it with a very small amount of overshoot. Brightness= 38% (according to preferences and lighting). The pixel response requirements are slacker at such frame rates and the visual fluidity is greatly limited by the frame rate itself. Again, we suggest you use Fast for best results. Nvidias website lists a 48 240Hz VRR, which would match AMD FreeSync. The screen is displaying reference photographs of this printed sheet, in both the same order as printed (right side) and reverse order (left side). Our recommended settings are below. Buy from Amazon The luminance uniformity was quite good. We consider either Fast or Super Fast optimal here, both being very well-tuned and difficult to distinguish from one another in practice. The driver setting change noted in the article setting Output dynamic range to Full is the simplest method. But far from poor. There was borderline significant deviation above the central region (DeltaE 3.0), with no significant deviation recorded elsewhere. A slight difference was that the floor of operation was 80Hz (80fps) on our Nvidia GPU. 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. The USB port to the left, as viewed from the rear, supports fast-charging. For the lowest levels of perceived blur its also important that the monitor performs its pixel responses rapidly. Brightness can be raised to compensate. This reference screen shows no noticeable powdery trailing but a little overshoot instead. But being able to change the power LED colour to suit your mood is a nice little touch. Slight changes could be observed at the very edges for some shades, such as the purple of Leelas hair gaining a bit of an extra red vs. blue hue to the purple more pronounced if sitting close to the screen. Screen surface imparts a bit of graininess to lighter content Alternatively, static interlace patterns may be seen with some shades appearing as faint horizontal or vertical bands of a slightly lighter and slightly darker version of the intended shade. In the . All but the final pattern was distinct from the background, with the final pattern faintly visible although a bit fainter than it could be. The colour reproduction was a relative strength of this monitor and a good step up from competing models with other panel types. It was free an obvious pink hue or saturation shifts that youd observe on models with weaker colour consistency. The Fast setting was quite close to the reference here, with slightly stronger but still by no means extreme overshoot. There were no clear flashes of saturated red, orange or green or shifts between these with a bit of head movement. Although not nearly as pronounced or obvious as stepping up from 60Hz to 144Hz (or even 120Hz). The USB port to the left, as viewed from the rear, supports fast-charging. You could assign such settings to Game 2 or Game 3 as well as theyre identical its easy to flick between these presets and another one by assigning them to a Shortcut Key in the OSD.
