There is no FreeSync support, which is a bit unusual in todays market. Its possible newer Nvidia GPUs, including their RTX series, support this expanded range or it may have just been misreported on the website. Lagom contrast tests The monitor offers fairly comprehensive sRGB coverage (99%), with a very small amount of under-coverage. It's an IPS panel so viewing angles . At 60Hz we measured a slightly higher but still reasonable 6.47ms. 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. The images below show the refresh rates available in the native Full HD resolution. In contrast to models with G-SYNC modules, which feature variable overdrive that re-tunes things dynamically to a wide range of different refresh rates. It was free from the sort of shifts in perceived gamma that can significantly mask dark detail in some regions of the screen whilst revealing too much detail elsewhere. Brighter elements stood out well against darker surroundings and the detail levels for most of the screen were appropriate. Features & Aesthetics It is satin black plastic with a blended light grey Alienware logo in the centre, the same width as the stand neck. This indicates a low viewing angle dependency to the gamma curve of the monitor, typical for an IPS-type panel. Following some tweaking in the OSD, things were brought more in-line with our target white point. We didnt readily observe either artifact type at high or relatively high refresh rates (100Hz+). The dark desktop background highlights IPS glow, which creates an obvious bloom as viewing angles become steeper. As shown in the image above, the monitor uses the usual RGB (Red, Green and Blue) stripe subpixel layout. Refresh rate: 240Hz. The setting is listed as Wait for Vertical Refresh. Any issues identified with FreeSync that were isolated to a specific title would indicate an issue with the game or GPU driver rather than the monitor as well. You also have to sacrifice resolution and screen size, which isn't ideal for more casual gamers with mixed preferences. The monitor was left to run for over 2 hours before readings were taken and observations were made. This worked exactly as its designed to, removing tearing and stuttering by ensuring the refresh rate stuck to a multiple of the frame rate. With VSync off the frame rate is free to climb as high as the GPU will output (potentially >240fps). Its important to reduce blue light exposure in the hours leading up to sleep, as its stimulating to the body and affects sleep hormones. Slight pixel responsiveness weaknesses for some transitions, a bit of overshoot creeps in at reduced refresh rates and no strobe backlight setting The strong colour consistency ensured shades maintained appropriate richness throughout the screen, without the saturation shifts youd see on VA or TN models. Compare prices on Alienware AW2521HF 25" Gaming Full HD IPS 240Hz Monitors. In this case appropriate richness and saturation was maintained throughout. The colour temperature uniformity was good. And not blended enough (blocky or banded) lower down due to low perceived gamma. But not the strong saturation levels youd see from models with more generous gamuts. R 18%, G 18%, B 23%. Disabling VRR now has a more pronounced effect on pixel response behaviour, with both the Super Fast and Extreme settings introducing very obvious bright and colourful overshoot. Its something were sensitive to, as long-time readers of our website will be well aware. Colour gamut 'Test Settings' Some models are specifically validated as G-SYNC compatible, which means they have been specifically tested by Nvidia and pass specific quality checks. The monitor was left to run for over 2 hours before readings were taken and observations were made. And the lack of tearing and stuttering was very nice indeed, if youre sensitive to such things. This indicates that the monitor has been specifically tested by Nvidia and passes specific quality checks. Integrated cable routing allows for easy adaptability, and Cherry MX Red switches provide consistent high-performance gaming. It still provides useful visual demonstrations and explanations which help reinforce some of the key points raised in the written piece. This gives the monitor the potential to output most shades within the sRGB colour space, with just a touch of extra vibrancy. Dell AW2521HF Review: 1080p 240Hz IPS . Pixel response behaviour was similar under the Fast setting whether Adaptive-Sync was active or not both in this test and more broadly. As things dipped even further, below the 48fps (48Hz) floor of operation for FreeSync, the monitor employed LFC (Low Framerate Compensation). The images below are pursuit photographs taken using the UFO Motion Test for ghosting, with the test running at its default speed of 960 pixels per second. Overall it put in a respectable performance for the panel type and will keep a broad spectrum of gamers happy, from casual to competitive. The colour temperature uniformity was good. Any issues identified with FreeSync that were isolated to a specific title would indicate an issue with the game or GPU driver rather than the monitor as well. The Alienware AW2521HF sports a 25-inch IPS panel with a 1920 x 1080 resolution, 240Hz refresh rate, and 1ms response time. Press OK, then turn the monitor off then on again so that it re-establishes connection the technology should now be active. Worth looking at analytic reviews for settings adjustment to colour/refresh rates etc. Some would prefer a wider gamut for extra vibrancy Less pronounced than youd see on TN or VA models. This is exactly what the Dell Alienware AW2521HF delivered. Typical gaming monitors usually have a response time of 1 to 6 ms. All but the final pattern was distinct from the background, with the final pattern faintly visible although a bit fainter than it could be. It requires huge visual sacrifices and very specific content to be shown on the screen. Conclusion That enables the lighting. 1080p at 24.5 inches is on the small and low-res side, but again, the monitor is designed for competitive esports gaming, where you want to be able to see the entire screen without darting your eyes around. The rather thick monitor sits atop a two-legged stand with no adornments other than a few "G-Sync" and "360Hz" stickers that you can pull right off. Input lag sits at 2.75ms, so there is no need to worry about delays or de-synced instances during competitive play. Bracketed numbers in our analysis refer to shades on the printed sheet or right side of the screen if theyre ordered consecutively from top left to bottom right. The numbered Game presets could also be used as a base as they offer the same flexibility. There is also a 3.5mm jack for analog audio, but there are no speakers with this model. And Variable Backlight is an effective dynamic contrast feature. With respectable graphics settings and more intense action it wasnt uncommon to see dips below 100fps, perhaps closer to 60fps on average. FreeSync requires a compatible AMD GPU such as the Radeon RX 580 used in our test system. Dieser Artikel enthlt Informationen zu integrierten Selbsttests (BIST, auch als integrierte Diagnose oder BID bezeichnet) und Diagnosetests der Selbsttestfunktionsprfung (STFC), die auf Dell Monitoren verfgbar sind. The full HD resolution of the Alienware AW2521HF isnt as impressive nowadays, but it is still the universal format for competitive gaming. Such an option does usually exist it may be called sync every frame or something along those lines rather than simply VSync. And more of a futuristic prop from a sci-fi movie kind of way. Learn how your comment data is processed. A slight difference was that the floor of operation was 80Hz (80fps) on our Nvidia GPU. In this case, overshoot (inverse ghosting) including some colourful bright halo trailing due to aggressive pixel overdrive. Contrast Gamboge (23) verged too much on a mustard yellow without a suitably warm golden hue, too. We wish the brand included an upgraded pair for the price which is quite steep, but built-ins are rarely missed since the intended audience will most likely have gaming headsets or speakers. Youll notice the gold-plated contacts in the stand when snapping it onto the panel. Using this method, we calculated 2.63ms (under 2/3rds of a frame at 240Hz) of input lag. With VSync off the frame rate is free to climb as high as the GPU will output (potentially >240fps). Also note that the listed refresh rates are the same via suitable versions of HDMI and DP and that a 4k x 2k, 3840 x 2160 downsampling mode is not included. Timestamps: The stand is height, swivel, and tilt adjustable for optimal ergonomics, and there's a cable management hole on the bottom for you to route all your connections. But there wasnt a strong coarse graininess nor a strong smeary appearance, either. To maximise colour accuracy within the sRGB colour space, for colour-managed workflows, full calibration and profiling with a colorimeter or similar device is recommended. Without FreeSync active and VSync disabled, youd get obvious tearing from the lack of synchronisation between frame and refresh rate. There are again varying levels of trailing behind the UFOs due to weaknesses in pixel responsiveness, but this takes a different form to at 60Hz. There was borderline significant deviation above the central region (DeltaE 3.0), with no significant deviation recorded elsewhere. You should ensure the GPU driver is setup correctly to use FreeSync, so open AMD Radeon Software, click Settings (cog icon towards top right) and click on Display. The consistency is also very good in most cases, superior to VA models and far superior to TN models (references. It doesnt show strong graininess or a heavily smeared appearance, however. At 240Hz, above, the UFOs again appear more sharply focused again with clearer internal detailing. But some users dont find such issues as noticeable and wont benefit as much from FreeSync. On some monitors, particularly but not exclusively those with high refresh rates, interlace patterns can be seen during certain transitions. The perceived blur was therefore dominated by eye movement and the monitor put its 240Hz refresh rate to good use. This resulted in a more noticeable powdery trailing with a greater effect on perceived blur. The OSD controls are located towards the bottom left. The greyscale gradient appeared smooth without obvious banding or dithering. It must be remembered that uniformity varies between individual units and you can also expect variation beyond the points measured. For the lowest levels of perceived blur its also important that the monitor performs its pixel responses rapidly. No saturation losses towards the bottom or edges as youd see from other panel types. Disabling VRR now has a more pronounced effect on pixel response behaviour, with both the Super Fast and Extreme settings introducing very obvious bright and colourful overshoot. A futuristic sci-fi prop look which some will find quite endearing. A slight reduction in powdery trailing at the expense of a bit of overshoot being introduced was the trade-off when stepping up the level, but the differences were not too profound. Today's best Alienware 25 Gaming Monitor AW2521H deals, We check over 250 million products every day for the best prices, Alienware 25 Gaming Monitor AW2521H: Price Comparison. Subtle details such as dark-coloured irises would be more distinct with stronger static contrast and appropriate perceived gamma, but they were still as visible as wed expect for most of the screen given the static contrast. Even on this title where there are lots of high contrast transitions, with bright objects against much darker backgrounds, there was nothing that really caught the eye as a clear weakness. You should then ensure that the first slider, Radeon FreeSync is set to Enabled as shown below. Dark areas with just a few point sources of light illuminating are common on this title, including dark tombs and passageways. Its something that will be more pronounced if youre sitting closer to the screen, are using a high brightness setting or have strong backlight bleed or clouding which can bring it out more noticeably. The AlienFX lighting system allowed some degree of customisation and some elements are visible from the front, but it was our wall who got the most enjoyment out of the light show. You can also create custom scenarios linked to specific games in the Alienware Command Center app. The camera is mounted slightly above centre so that the image is representative of what the eye sees from an ergonomically correct viewing position. All but the final pattern was distinct from the background, with the final pattern faintly visible although a bit fainter than it could be. When you open up Nvidia Control Panel, you should then see Set up G-SYNC listed in the Display section. It requires huge visual sacrifices and very specific content to be shown on the screen. The red block appeared a fairly rich red throughout. Shadow of the Tomb Raider told a similar story. The device stands stable even if you pound on your desk, plus it doesnt creak or choke when you try to adjust the screen. ComfortView 2.1 6336K Intended as a Low Blue Light (LBL) setting, but very ineffective. The bottom line; strong responsiveness and colour performance from a stylish and well-priced monitor. IPS glow eats away at detail, particularly near bottom corners. Unless youre frequently passing this boundary its not something youre likely to notice or care about, though. Note that 120Hz is listed as a PC resolution, rather than in the Ultra HD, HD, SD list. Every player has a different notion about the ideal . 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. 80 240fps). And not blended enough (blocky or banded) lower down due to low perceived gamma. The representation of shades in this image depends on the camera and your own screen, its not designed to show exactly how the shades appear in person. The very low signal delay of this model also aided the connected feel, but the very high frame and refresh rate combination also helped. Create an account to follow your favorite communities and start taking part in conversations. This could be reduced by turning up the Response Time setting, but as explored earlier with Test UFO youd need Adaptive-Sync enabled and suitably high frame rates to avoid strong overshoot if doing that. Timestamps: This reflects another significant reduction in perceived blur due to eye movement. 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. VA models have black crush centrally which masks some detail, whilst some excessive detail can be observed towards the bottom and side edges from a normal viewing position. Above this dropdown list theres a toggle for Radeon Enhanced Sync. Extreme in particular showed very strong and eye-catching overshoot. We made various changes to the Custom Color preset for our Test Settings. The colour reproduction was a relative strength of this monitor and a good step up from competing models with other panel types. Conclusion The image below shows a printed reference sheet of 24 sRGB shades, included as part of the Datacolor SpyderCHECKR 24 package. The deviation between each quadrant and the quadrant closest to the 6500K (D65) daylight white point target was analysed and a DeltaE value assigned. Conclusion Diesem Produkt sind keine Videos zugeordnet. The refresh rate was put to very good use overall; fairly strong pixel responsiveness, low input lag and no noticeable overshoot. The monitor has distinctive Alienware styling. Without FreeSync active and VSync disabled, youd get obvious tearing from the lack of synchronisation between frame and refresh rate. If you activate the Frame Rate feature under Game Game Enhance Mode in the OSD, this will display the refresh rate of the display and therefore indicate the frame rate if FreeSync is active and the frame rate is within the variable refresh rate range of the display. This indicates a low viewing angle dependency to the gamma curve of the monitor, typical for an IPS-type panel. Lagoms viewing angle tests help explore the idea of colour consistency and viewing angle performance. In the example of white text against a shaded backdrop, this only occurred at certain grey levels for the background, so not all dark shades would trigger it. Its a shame ULMB cant be used with G-Sync. And not blended enough (blocky or banded) lower down due to low perceived gamma. The connected feel and perceived blur took a real hit here, but the technology did its thing to get rid of tearing and stuttering all the same. Theres no strobe backlight mode on this model, but they come with their own compromises that not everyone is willing to make. Negatives This requires that the frame rate comfortably exceeds the refresh rate, not just peaks slightly above it. The brightest point recorded was quadrant 5 in the centre of the screen (168.2 cd/m). Pixel response behaviour was similar under the Fast setting whether Adaptive-Sync was active or not both in this test and more broadly. Above this dropdown list theres a toggle for Radeon Enhanced Sync. Note that we have no way to accurately measure input lag with Adaptive-Sync active in a variable refresh rate and frame rate environment. Its not that different than typical IPS screens in this regard. With VRR off the Super Fast and moreover Extreme settings show strong overshoot in the form of bright halo trailing. The numbered Game presets and Custom Color are most flexible as they allow you to adjust the colour channels and saturation levels. Or is it just a normal issue and I should ask for the refund and buy another 240hz monitor? Any issues identified with FreeSync that were isolated to a specific title would indicate an issue with the game or GPU driver rather than the monitor as well. The consistency is also very good in most cases, superior to VA models and far superior to TN models (references here). Where possible, youll be redirected to your nearest store. It was masked by a bit of graininess from the screen surface as well. 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. Dark areas with just a few point sources of light illuminating are common on this title, including dark tombs and passageways. As with AMD FreeSync this technology worked very well, although there was a momentary stutter when it activated or deactivated. This title offered suitable graphics options to test the full gamut of refresh rates supported by the monitor. All three rows of the test are analysed (dark, medium and light background) to show a range of pixel transitions. There is a little light powdery trailing behind the UFOs, particularly for the dark and medium backgrounds. Similar to above, as with Game 2 and Game 3. The setting is found in Manage 3D settings under Vertical sync, where the final option (Fast) is equivalent to AMDs Enhanced Sync setting. Our RX 580 is far from a powerhouse of a graphics card, so maintaining 240fps was very tricky. Christian Eberle is a Contributing Editor for Tom's Hardware US. 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. The AW2521H also includes ULMB up to 240 Hz. Press question mark to learn the rest of the keyboard shortcuts. The colour reproduction was a relative strength of this monitor and a good step up from competing models with other panel types. It soon disappeared when using monitor normally. The final point to note is that FreeSync only removes stuttering or juddering related to mismatches between frame rate and refresh rate. If you activate the Frame Rate feature under Game Game Enhance Mode in the OSD, this will display the refresh rate of the display and therefore indicate the frame rate if FreeSync is active and the frame rate is within the variable refresh rate range of the display. We consider either Fast or Super Fast optimal here, both being very well-tuned and difficult to distinguish from one another in practice. Styling is minimalist but distinctly Alienware. As of driver version 417.71, users with Nvidia GPUs (GTX 10 series and newer) and Windows 10 can also make use of this Variable Refresh Rate (VRR) technology. Some would prefer a wider gamut for extra vibrancy Given the pleasing responsiveness and colour performance, nice overall build and (subjectively speaking) styling we feel this is an excellent 240Hz Full HD model overall. Our recommended settings are below. 360 Hz is seriously fast, and even just moving dialog boxes around the desktop looked almost other-worldly. As the frame rate dropped we noticed an increase in overshoot. This requires that the frame rate comfortably exceeds the refresh rate, not just peaks slightly above it. As usual, pay little attention to this figure as its highly misleading. 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. Responsiveness in games and movies The strong consistency was also very evident when considering Laras glowing and all-too-perfect complexion. 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. Whilst observing a black screen in a dark room, using our Test Settings, we noticed a small amount of backlight bleed and minor clouding. Its something were sensitive to, as long-time readers of our website will be well aware. We have no major complaints about this product, plus we think its pricing is more palatable and comparable to its competitors. When a monitor is used in this way, it is something which Nvidia refers to as G-SYNC Compatible. This was used for our own viewing comfort in the evenings but not for specific testing of the monitor we therefore refer to these as our Relaxing evening viewing settings. 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. Nvidia Adaptive-Sync (G-SYNC Compatible) The refresh rate was set to 240Hz in Windows, although this didnt significantly affect the values or observations on this table. 27" Gigabyte AORUS FI27Q Given the intended uses for monitor, inter-unit variation and decent performance following OSD tweaking alone we will not be using any ICC profiles for this review or including any measurements or graphs using them. VA monitors perform better in this regard, but IPS has better color consistency and viewing angles in exchange for this limitation. At 60Hz we measured a slightly higher but still reasonable 6.47ms. The Fast setting only showed a relatively small amount of this, whilst the Super Fast and Extreme settings ramped this up. My god, some people are dumb if you have to ask who this is for, it's not for you. Intended as a Low Blue Light (LBL) setting, but very ineffective. Note that there is always some disparity between how emissive objects (monitor) and non-emissive objects (printed sheet) appear. The connected feel and perceived blur took a real hit here, but the technology did its thing to get rid of tearing and stuttering all the same. Most users will probably wish to enable VSync when using FreeSync to ensure that they dont get any tearing. The screen surface was a touch on the grainy side when viewing lighter content, although this wasnt a strong layered graininess or excessively sandy appearance thankfully. VRR off did not significantly affect the pixel response behaviour at this refresh rate. Note that there is always some disparity between how emissive objects (monitor) and non-emissive objects (printed sheet) appear. The connected feel and perceived blur took a real hit here, but the technology did its thing to get rid of tearing and stuttering all the same. RGB | 93 | 93 | 100 | 65 Brightness | 90 Contrast | 1 Dark Stabalizer | Extreme. I did find that the target white point was just slightly warm, though backing off the blue in the Custom Color preset fixed this right up. You can adjust the color of this light in the on-screen display or turn it off entirely. The dark desktop background highlights IPS glow, which creates an obvious bloom as viewing angles become steeper. Youd therefore select either the third or fourth option in the list, shown in the image below. The colour gamut provided just a bit of extension beyond sRGB, injecting some extra vibrancy without the strong saturation of a much more generous colour gamut. However; the Gain controls required different adjustments. The brightest point recorded was quadrant 5 in the centre of the screen (168.2 cd/m). Given the pleasing responsiveness and colour performance, nice overall build and (subjectively speaking) styling we feel this is an excellent 240Hz Full HD model overall. Monitor. G Gain= 88% As an Amazon Associate I earn from qualifying purchases made using the below link. 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. On the panels top edge is an ambient light sensor. This resulted in a more noticeable powdery trailing with a greater effect on perceived blur. The RTX 3080 is a . This reflects a moderate amount of perceived blur due to eye movement and is something shared with the reference screen. Over 30 repeat readings were taken to help maximise accuracy. Gamma 'Test Settings' We also observed the contrast performance of Star Wars: The Rise of Skywalker. Around 1000:1 even following adjustments to our Test Settings. In the image above you can see that the monitor is validated as G-SYNC Compatible (or you could, if Nvidia Control Panel displayed the entire text instead of cutting it off). The monitor didnt put form over function, either, and was solidly built with good ergonomic flexibility and VESA mounting options. The remaining blocks were displayed appropriately with good steps up in brightness. turn on g sync,set the response to extreme, cap frams at 237, turn up brightness and contrast to 90 or something if you can i would return it and get something else, i have it since launch and i regret it. We therefore consider Fast the optimal setting at 60Hz. There is a little light powdery trailing behind the UFOs, particularly for the dark and medium backgrounds. The strong colour consistency ensured shades maintained appropriate richness throughout the screen, without the saturation shifts youd see on VA or TN models. IPS glow eats away at detail, particularly near bottom corners. This displays the current refresh rate of the monitor and will reflect the frame rate if its within the main variable refresh rate window (e.g. So when it was revealed that the brand was releasing the Alienware AW2521HF, a 240Hz, 24.5-inch, 1ms, IPS panel monitor for sub $500, people got excited and rightfully so. The experience wasnt as cinematic as on models with much stronger static contrast, particularly in a dimly lit room. Strong colour consistency and slight extension beyond sRGB, giving a rich and natural image without potentially overbearing saturation The stand with the Alienware AW2521HF offers full flexibility which allows you to tilt, swivel, pivot, and raise or lower the height of the screen. Last Modified: 07 FEB 2023. The Lagom tests for contrast allow specific weaknesses in contrast performance to be identified. Conclusion Further information on supporting our work. The stand has a robust sculpted appearance, designed to look stylish without sacrificing ergonomics; tilt (5 forwards, 21 backwards), swivel (20 left, 20 right), height (130mm or 5.12 inches) and pivot (90 clockwise or anti-clockwise rotation into portrait) adjustment is included. With some more noticeable halo trailing by about 80fps (80Hz). The maximum luminance recorded in this table was 427 cd/m, whilst the minimum white luminance recorded was 33 cd/m.
