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. Silky smooth and the response . 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. Whilst its 24.5 screen with Full HD resolution doesnt deliver a staggering pixel density or the same useful desktop real-estate as some models, its a relatively easy resolution to drive at high frame rates. 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. The Alienware AW2521HFL is a FreeSync Premium gaming monitor, but its also compatible with Nvidia's G-Sync Compatible mode. 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. Its something were sensitive to, as long-time readers of our website will be well aware. Pixel response behaviour was similar under the Fast setting whether Adaptive-Sync was active or not both in this test and more broadly. This aspect varies between every unit, so its possible to get one with worse or fewer symptoms. Main: Roasted chicken with roasted potatoes and green beans. The following observations were made from a normal viewing position, eyes ~70cm from the screen. The monitor can also be set to 120Hz although not documented in this testing, results were very much comparable to 144Hz. The default color accuracy is decent with deltaE average sitting at 2.89, but it could still use some improvements. The backlight hits 400 cd/m2, while the contrast ratio is rated at 1000:1 like most IPS panels. This figure is influenced both by the element of input lag you see (pixel responsiveness) and the element you feel (signal delay). The monitor performed well here, without clear shifts in saturation or colour tone. As usual we tested a broad range of game titles using FreeSync and found the experience similar across the board. They often catch the eye due to their dynamic nature, on models where they manifest themselves in this way. 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). 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. Our suggestions regarding use of VSync also apply, but youre using Nvidia Control Panel rather than AMD Radeon Software to control this. Brightness= 38% (according to preferences and lighting). The blue block appeared consistent royal blue throughout. There is no FreeSync support, which is a bit unusual in todays market. On the GPU driver side recent AMD drivers make activation of the technology very simple and something that usually occurs automatically. 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. Perceived blur (pursuit photography) A medium matte anti-glare screen surface is used, as explored shortly. This is the default expected by modern operating systems such as Microsoft Windows and Apples MacOS. Such an option does usually exist it may be called sync every frame or something along those lines rather than simply VSync. 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. Screen surface imparts a bit of graininess to lighter content 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. 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. Buy Alienware AW2521HF 24.5 inch Full HD (1920x1080) Gaming Monitor, 240Hz, IPS, 1ms, AMD FreeSync Premium, NVIDIA G-SYNC Compatible, DisplayPort, 2x HDMI, 5x USB 3.0, Adjustable Stand, 3 Year Warranty at Amazon UK. 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. The colour reproduction was a relative strength of this monitor and a good step up from competing models with other panel types. The technology worked well and offered a very similar experience to AMD FreeSync. Lagoms viewing angle tests help explore the idea of colour consistency and viewing angle performance. The monitor can also be set to 120Hz although not documented in this testing, results were very much comparable to 144Hz. The Super Fast setting just slightly reduces this, replacing it with a very small amount of overshoot. Whilst its 24.5 screen with Full HD resolution doesnt deliver a staggering pixel density or the same useful desktop real-estate as some models, its a relatively easy resolution to drive at high frame rates. 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. Now, we have fast IPS, which brings back good viewing angles and better color saturation. The monitor didnt put form over function, either, and was solidly built with good ergonomic flexibility and VESA mounting options. Note that individual units and preferences vary, so these settings are simply a suggestion and wont necessarily be optimal in all cases. The dark desktop background highlights IPS glow, which creates an obvious bloom as viewing angles become steeper. But we appreciate some users still like to use profiles and some aspects such as gamut mapping for colour-aware applications can be useful. Some users prefer to leave VSync enabled but use a frame rate limiter set a few frames below the maximum supported (e.g. 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. Alienware Aurora R14 RTX 3080 PC for $1518.99. The 360 Hz refresh rate is the current pinnacle of smooth response and the lowest available input lag. This indicates that the monitor has been specifically tested by Nvidia and passes specific quality checks. There were some slightly more pronounced weaknesses for a minority of pixel transitions, for example when observing white or very light objects such as in-game text against a dark and shadowy background. Slight pixel responsiveness weaknesses for some transitions, a bit of overshoot creeps in at reduced refresh rates and no strobe backlight setting Ensure the Enable G-SYNC, G-SYNC Compatible checkbox and Enable settings for the selected display model is checked as shown below. The greatest deviation from this occurred at quadrant 6, to the right of this (151.5 cd/m, which is 10% dimmer). As an Amazon Associate I earn from qualifying purchases made using the below link. We observed some faint vertical dynamic interlace patterns at ~60Hz and below, but these were not particularly obtrusive in our view. 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. 27" Gigabyte AORUS FI27Q The monitor performed well here, without clear shifts in saturation or colour tone. IPS glow also featured, but appropriate room lighting took the edge off this. Less pronounced than youd see on TN or VA models. Note that there is always some disparity between how emissive objects (monitor) and non-emissive objects (printed sheet) appear. There is a little light powdery trailing behind the UFOs, particularly for the dark and medium backgrounds. 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. As noted earlier, AMD FreeSync makes use of Adaptive-Sync technology on a compatible monitor. We made various changes to the Custom Color preset for our Test Settings. Note that wavy patterns surrounding some UFOs in the background are slight image retention. You need to make sure FreeSync is set to On in the Game section of the OSD. 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. Check price. The contrast gradients were displayed well, with distinct brightness steps in most cases. The depth of the dark shades and overall atmosphere created was certainly not as impressive as on models with much stronger static contrast. The bezel is visible when the powers on, but is only 7mm wide at the top and sides. The monitor itself must support VESA Adaptive-Sync for at least one of its display connectors, as this is the protocol that FreeSync uses. Resolution: 1920x1080. You also have to sacrifice resolution and screen size, which isn't ideal for more casual gamers with mixed preferences. We stuck with the Fast setting for the subjective testing below. The Lagom text appeared a blended grey throughout, with a slight red hue to the striping of the text. Some game engines will also show stuttering (or hitching) for various other reasons which wont be eliminated by the technology. The Alienware AW2521H has both. You should then ensure that the first slider, Radeon FreeSync is set to Enabled as shown below. For users who wish to disable Adaptive-Sync they can just stick with Fast without worrying about strong overshoot, too. Thankfully, this test showed virtually no flickering, and Blur Busters' UFO test showed incredibly clear motion with almost no ghosting. Even if such dips were very slight, without FreeSync active and VSync enabled theyd cause obvious stuttering. The Alienware AW2521HF is extremely fast when it comes to pixel response times, so blur-free gaming is entirely possible. NY 10036. We also tested movie content, which was much more limited in frame rate (generally 24fps, 30fps or 60fps). The image below shows a printed reference sheet of 24 sRGB shades, included as part of the Datacolor SpyderCHECKR 24 package. It indicates a very low signal delay at 240Hz which even sensitive users shouldnt find bothersome. AMD LFC (Low Framerate Compensation) is also supported by this model, which means that the refresh rate will stick to multiples of the frame rate where it falls below the 48Hz (48fps) floor of operation for FreeSync. And more of a futuristic prop from a sci-fi movie kind of way. Colour gamut The third and fourth blocks were slightly fainter than they should be, although still distinguishable. A very slight shadowy trail behind the UFO, but overall rather similar to the Fast setting in appearance. The screen surface imparted a bit of graininess to lighter content, so it wasnt as smooth as it couldve been. As an Amazon Associate I earn from qualifying purchases made using the below link. The gamma curve is shown below for our Test Settings, with similar performance here to the factory defaults. 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 Fast setting only showed a relatively small amount of this, whilst the Super Fast and Extreme settings ramped this up. This is explored alongside the OSD itself in the video below. Nvidias G-SYNC Compatible Mode is only supported via DisplayPort. Below you can see how things appear with refresh rate ramped up to 240Hz. Some models are specifically validated as G-SYNC compatible, which means they have been specifically tested by Nvidia and pass specific quality checks. This resulted in a more noticeable powdery trailing with a greater effect on perceived blur. This isnt a strong stuttering and isnt something youll generally notice or find bothersome unless youre frequently passing the boundary. This is exactly what the Dell Alienware AW2521HF delivered. These were briefly explored in the OSD video, but for the purposes of this table well be looking at manual adjustments and settings we feel have more utility. And twice as much when compared to 120Hz or 1.67 times as much compared to 144Hz. Responsiveness (Adaptive-Sync) Every player has a different notion about the ideal setting for PC . Youll also notice G-SYNC Compatible listed under Monitor Technology in this section, as shown below. The SpyderX Elite was also used to analyse variation in the colour temperature (white point) for the same 9 quadrants. Colour in games and movies The Alienware AW2521HF sports a 25-inch IPS panel with a 1920 x 1080 resolution, 240Hz refresh rate, and 1ms response time. Outside of the concealed port area, further down and in the centre, there are 2 further USB 3.0 ports and a 3.5mm headphone jack. He's a veteran reviewer of A/V equipment, specializing in monitors. The table below shows these values as well as the percentage deviation between each quadrant and the brightest point measured. No saturation losses towards the bottom or edges as youd see from other panel types. Compared to at 60Hz, or indeed a 60Hz monitor, youre getting up to 4 times as much visual information pumped out every second. With the Fast setting, theres just a faint hint of powdery trailing, sticking very close to the UFO and very light in appearance. Alienware AW2521HF 24.5 inch Full HD (1920x1080) Gaming Monitor, 240Hz, IPS, 1ms, AMD FreeSync Premium, NVIDIA G-SYNC CompatibleAmazon Affiliate Link: https:. The pixel response requirements for optimal performance have increased significantly due to the significant bump up in refresh rate. The AW2521HF supports FreeSync Premium via DP 1.2a and HDMI 2.0 on compatible GPUs and systems. It wont work in concert with G-Sync but does make a visible difference in motion resolution. IPS glow eats away at detail, particularly near bottom corners. 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. You can even improve the color settings by simply tweaking the RGB controls of a monitor which will reduce the warmth of the screen and produce a more balanced image. 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 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). The remaining blocks were displayed appropriately with good steps up in brightness. And the lack of tearing and stuttering was very nice indeed, if youre sensitive to such things. Visibility is also excellent, so your eyes wont have trouble reading walls of text and the like. Brighter elements stood out well against darker surroundings and the detail levels for most of the screen were appropriate. This characteristic makes the monitor a practical choice since you dont need to stick to one GPU brand for the rest of its lifespan.
