Whilst both elements are important, eye movement is usually the dominant factor on modern monitors. Even the best VA performers show quite pronounced shifts in saturation for such pastel shades when theyre shown towards peripheral sections of the screen rather than centrally. The dark desktop background highlights IPS glow, which creates an obvious bloom as viewing angles become steeper. The green block appeared a consistent saturated chartreuse shade throughout. 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. Somewhat yellow compared to on models with a much more generous colour gamut, but less so than models that very strictly follow the sRGB gamut. The backlight hits 400 cd/m2, while the contrast ratio is rated at 1000:1 like most IPS panels. With the Fast setting, theres just a faint hint of powdery trailing, sticking very close to the UFO and very light in appearance. All but the final pattern was distinct from the background, with the final pattern faintly visible although a bit fainter than it could be. You also have to sacrifice resolution and screen size, which isn't ideal for more casual gamers with mixed preferences. The colour reproduction was a relative strength of this monitor and a good step up from competing models with other panel types. The lower 1080p resolution ensures you can push as many frames as possible to reach that super-fast refresh rate, so while it isn't ideal for desktop work, it's all your graphics card can probably handle for gaming this smooth. Strong consistency due to IPS-type panel, without the perceived gamma and saturation shifts associated with TN or VA panels. Test Settings (see below) 2.1 6498K The image appears rich and natural overall, with good variety. And that was its excellent gamma consistency. Every player has a different notion about the ideal . The blue block appeared consistent royal blue throughout. The Dell Alienware supports a variable refresh rate range of 48 240Hz. You need to make sure FreeSync is set to On in the Game section of the OSD. According to user feedback the monitor runs at 120Hz on the PS5, as of the April 2021 update for the console. The setting is listed as Wait for Vertical Refresh. Alienware Tenkeyless Gaming Keyboard (AW420K) - Computer Keyboard The Alienware AW2521HF is a FreeSync monitor as indicated by the F in the model name, unlike the awaited 360Hz AW2521H which is exclusive to G-Sync. The monitor provided a rich and natural appearance to Battlefield V. The monitor provides comprehensive sRGB colour gamut coverage and a bit of extension beyond, but stays well short of extended colour spaces such as DCI-P3. Negatives And twice as much when compared to 120Hz or 1.67 times as much compared to 144Hz. 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 remaining blocks were displayed appropriately with good steps up in brightness. The experience wasnt as cinematic as on models with much stronger static contrast, particularly in a dimly lit room. The Response Time setting or Adaptive-Sync status didnt affect these observations. But we appreciate some users still like to use profiles and some aspects such as gamut mapping for colour-aware applications can be useful. Its something were sensitive to, as long-time readers of our website will be well aware. The AW2521HF supports FreeSync Premium via DP 1.2a and HDMI 2.0 on compatible GPUs and systems. 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. 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. It started to creep in a little bit even at the high double digit to very low triple digit frame rates. 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. window.__mirage2 = {petok:"zg2cYY5zq25POHOP6IsDfN8FBZJHLm773fg_fBtMlJU-1800-0"}; 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. 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 less of this behind the UFO cockpit for the medium background. When we say obvious, its very subjective sensitive users can certainly notice such things and it can be very nice indeed having them gone. The very low signal delay of this model also aided the connected feel, but the very high frame and refresh rate combination also helped. 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 25 Gaming Monitor | AW2521HF. The monitor delivered a very competent 240Hz performance, with only minor weaknesses as described earlier. It is effective but it reduces brightness and, in most cases, prevents the use ofFreeSync or G-Sync. Gamma consistency was good, ensuring detail levels were largely appropriate (IPS glow affected regions aside) throughout the screen. This is quite common on LBL settings as reducing the green channel negatively impacts contrast, but in this case it was rather noticeable and you were left with a warmish but very green image. FreeSync requires a compatible AMD GPU such as the Radeon RX 580 used in our test system. The environments looked in-place, with good variety and some good earthy browns and rich green shades. The perceived blur due to eye movement was also greatly reduced, much as demonstrated with the pursuit photos earlier on. 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. This title has a lot of high contrast scenes, with very dingy backgrounds and pulses of energy, explosions and lightsabers offering some illumination here and there. 1 comment. Resolution: 1920 x 1080 . Brighter elements stood out well against darker surroundings and the detail levels for most of the screen were appropriate. 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. The main feature from the front, as usual, is the screen face. Plus a bit of overextension, in the green to red region. We wont be going into this in detail as its a GPU feature rather than a monitor feature. This reflects a significant reduction in perceived blur due to eye movement. 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. The monitor was tested at 60Hz (directly below), 144Hz and 240Hz using all available Response Time settings; Fast, Super Fast and Extreme. Some isolated weaknesses such as bright markers or strongly illuminated objects against some shaded backgrounds leaving a powdery trail but as with our observations in BFV this wasnt really a major weakness. Rather than simply reflecting the pixel response elements. Dips below this were common. The following table shows this data, with blue highlights indicating the results under our Test Settings. At 240Hz, above, the UFOs again appear more sharply focused again with clearer internal detailing. Further information on supporting our work. This resulted in a more noticeable powdery trailing with a greater effect on perceived blur. Individual targets depend on individual uses, tastes and the lighting environment, however. But not the strong saturation levels youd see from models with more generous gamuts. The monitor didnt put form over function, either, and was solidly built with good ergonomic flexibility and VESA mounting options. Youll also notice G-SYNC Compatible listed under Monitor Technology in this section, as shown below. In our view the price is also very reasonable and highly competitive given whats on offer. It still provides useful visual demonstrations and explanations which help reinforce some of the key points raised in the written piece. Save my name, email, and website in this browser for the next time I comment. B Gain= 92% NY 10036. This requires that the frame rate comfortably exceeds the refresh rate, not just peaks slightly above it. Although this wont 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. This ate away at detail and lightened dark shades up in this region, but wasnt extreme. When you open up Nvidia Control Panel, you should then see Set up G-SYNC listed in the Display section. The pixel response requirements for optimal performance have increased significantly due to the significant bump up in refresh rate. Its not that different than typical IPS screens in this regard. And that was its excellent gamma consistency. Alienware AW2521HF 24.5 inch Full HD (1920x1080) Gaming - Amazon You can try these settings yourself to see which you prefer. When the frame rate rises above 240fps, the monitor will stay at 240Hz and the GPU will respect your selection of VSync on or VSync off in the graphics driver. Os artigos de conhecimento mais teis para o seu produto esto includos nesta seo. The green block appeared a consistent saturated chartreuse shade throughout. And not blended enough (blocky or banded) lower down due to low perceived gamma. Though its focus is premium gaming, the AW2521H is a decent all-around monitor for everyday use. Learn how your comment data is processed. Negatives The monitor performed well here, without clear shifts in saturation or colour tone. 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. 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. This reference screen shows no noticeable powdery trailing but a little overshoot instead. The first couple of blocks blended into the background well, which is usual for a monitor tracking the 2.2 gamma curve correctly. Luminance uniformity table Dark areas with just a few point sources of light illuminating are common on this title, including dark tombs and passageways. Author: Adam Simmons Note that individual units and preferences vary, so these settings are simply a suggestion and wont necessarily be optimal in all cases. Without FreeSync active and VSync disabled, youd get obvious tearing from the lack of synchronisation between frame and refresh rate. Responsiveness (Adaptive-Sync) Responsiveness in games and movies 5. No additional monitor drivers or ICC profiles were specifically loaded for the review. 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. Over 30 repeat readings were taken to help maximise accuracy. The colour gamut of the AW2521HF (red triangle) was compared with the sRGB reference colour space (green triangle), as shown in the image below. The rear of the screen continues the Alienware aesthetic, with the creatively named Dark Side of the Moon shade used extensively (or Lunar Light for the HFL model). Our article on responsiveness analyses the key factors affecting monitor responsiveness. On TN models you have things looking far too masked higher up the screen due to high perceived gamma. As usual we tested a broad range of game titles using FreeSync and found the experience similar across the board. Preset Mode= Game 1 The first couple of blocks blended into the background well, which is usual for a monitor tracking the 2.2 gamma curve correctly. Alienware AW2521HF review: "A great monitor with a very specific The article also covers a technique called pursuit photography, using a moving rather than stationary camera to capture motion in a way that reflects both elements of perceived blur. Whilst observing a black screen in a dark room, using our Test Settings, we noticed. The bottom line; strong responsiveness and colour performance from a stylish and well-priced monitor. Great price for (still) one of the best monitors in 1440p 165hz IPS category. Somewhat yellow compared to on models with a much more generous colour gamut, but less so than models that very strictly follow the sRGB gamut. A 1440p monitor at 144Hz with a good response time like the ViewSonic Elite XG270QG is going to be a better pick for most people, and at a much lower price. Best Mouse for Apex Legends; . 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. When a monitor is used in this way, it is something which Nvidia refers to as G-SYNC Compatible. Colour in games and movies RGB | 93 | 93 | 100 | 65 Brightness | 90 Contrast | 1 Dark Stabalizer | Extreme. With some more noticeable halo trailing by about 80fps (80Hz). All but the final pattern was distinct from the background, with the final pattern faintly visible although a bit fainter than it could be. With the AW2521HF, you need to connect the monitor up via DisplayPort and enable FreeSync in the Game section of the OSD. The monitor features the brands distinct Alienware treatment which packs a lot of firepower for our favorite hobby. The Alienware AW2521HF offers awe-inspiring gaming performance courtesy of its 240Hz IPS panel which is extra responsive while having great color quality. Nonetheless, we wouldnt describe the atmosphere as poor in an appropriately well-lit room either. While console gamers are getting excited about their new 120Hz refresh rates, PC hardware manufacturers continue to push the boundaries further, with 240Hz gaming monitors and even 360Hz gaming monitors packing as many frames into your eyeballs as possible. This diffusion also affects light emitted from the monitor, with a negative impact on the clarity and vibrancy potential of the screen. Warm 2.1 7053K Warmer than factory defaults, but far from Warm on our unit with a high colour temperature and cool tint to the image. But far from poor. 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. Using VRR improved pixel response behaviour for very high refresh rates, too, allowing the Extreme overdrive setting to be used without strong overshoot. That means that if the game is running between 48fps and 240fps, the monitor will adjust its refresh rate to match. They also come surprisingly close to the reference screen, with just a hint of powdery trailing for the dark background (top row) that isnt there on the reference. But if you max the backlight with G-Sync, its 48% dimmer with ULMB, so the change isnt constant. The experience wasnt as cinematic as on models with much stronger static contrast, particularly in a dimly lit room. The AW2521H uses one of these, along with a white LED edge-array backlight. It still helps demonstrate some of the relative differences between the original intended sRGB shade and what the monitor outputs, however. You can adjust the color of this light in the on-screen display or turn it off entirely. The final point to note is that FreeSync only removes stuttering or juddering related to mismatches between frame rate and refresh rate. There is various degrees of trailing behind the UFOs due to pixel response time weaknesses. Gameplay this responsive and smooth is truly addictive. Well therefore just focus Battlefield V for this section. At 60Hz we measured a slightly higher but still reasonable 6.47ms. Timestamps: Brighter elements stood out well against darker surroundings, complete with a bit of graininess from the screen surface but nothing extreme. 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. 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. We stuck with the Fast setting for the subjective testing below. Video inputs include two HDMI 2.0, limited to 240 Hz, and a DisplayPort 1.4, which is the one to use for G-Sync and 360 Hz (see our DisplayPort vs HDMI article for more). //3 represents significant deviation that most users could readily notice by eye. A sensitive camera and a utility called SMTT 2.0 was used assess the latency of the Dell Alienware AW2521HF. 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 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. Because each frame remains on the screen while the next one is drawn, it has been termed sample and hold. Self-illuminant panels, like plasma and OLED, redraw the image hundreds of times per refresh cycle, which means there is no blur, even at frame rates as low as 60 fps. Competing TN models certainly have something of a vertical detail gradient going on for dark content vertically, whilst VA models have black crush centrally and a bit of extra detail peripherally. This reflects another significant reduction in perceived blur due to eye movement. Contrast in games and movies And not blended enough (blocky or banded) lower down due to low perceived gamma. This is the default expected by modern operating systems such as Microsoft Windows and Apples MacOS. Below you can see how things appear with refresh rate ramped up to 240Hz. 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. The third and fourth blocks were slightly fainter than they should be, although still distinguishable. Panel Technology: In-Plane Switching (IPS), Connectivity: DisplayPort 1.2 x 1, HDMI 2.0 x 2, USB 3.0 x 4, 3.5mm Jack x 1, Dimensions with Stand(WxHxD): 21.90 x 16.58 x 9.92. 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. 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. Lagom contrast tests Contrast - 69. Note that there is always some disparity between how emissive objects (monitor) and non-emissive objects (printed sheet) appear. Compared to at 60Hz, or indeed a 60Hz monitor, youre getting up to 4 times as much visual information pumped out every second. 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. When we say obvious, its very subjective sensitive users can certainly notice such things and it can be very nice indeed having them gone. We stuck with the Fast setting for the subjective testing below. Still there are some weaker IPS performers out there in that respect. FreeSync requires a compatible AMD GPU such as the Radeon RX 580 used in our test system. 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. There were no clear flashes of saturated red, orange or green or shifts between these with a bit of head movement. 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. The ports are concealed beneath a removable plastic cover, facing downwards and include; AC power input (internal power converter), 2 USB 3.0 ports (plus upstream), 2 HDMI 2.0 ports, DP 1.2a and a 3.5mm audio line-out. Screen surface imparts a bit of graininess to lighter content Lagom contrast tests Not smeary in appearance, but it extended out a bit more and had a greater effect on perceived blur compared to the light powdery trailing described earlier. R 18%, G 18%, B 23%. Most pixel transitions were performed fast enough for a solid 240Hz experience, with either no additional trailing or just a little light powdery trailing in places.
