The backlight hits 400 cd/m2, while the contrast ratio is rated at 1000:1 like most IPS panels. At a basic level, a mismatch between the frame rate and refresh rate can cause stuttering (VSync on) or tearing and juddering (VSync off). As the frame rate dropped we noticed an increase in overshoot. 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. In this position the top of the stand neck pokes up an additional ~40mm (1.57 inches) above the top edge of the screen surface. Click ‘Settings’ (cog icon towards top right) and click ‘Graphics’. 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. Some users prefer to leave VSync enabled but use a frame rate limiter set a few frames below the maximum supported (e.g. All but the final pattern was distinct from the background, with the final pattern faintly visible although a bit fainter than it could be. This reference screen shows no noticeable ‘powdery’ trailing but a little overshoot instead.With ‘VRR off’ the ‘Super Fast’ and moreover ‘Extreme’ settings show strong overshoot in the form of bright ‘halo’ trailing. It’s again important to note that individual unit vary when it comes to uniformity and that deviation beyond the measured points can be expected. This model is HDR 400-capable, but it can only offer minor improvements to the appearance of your compatible games and media. This reflects a significant reduction in perceived blur due to eye movement. It still helps demonstrate some of the relative differences between the original intended sRGB shade and what the monitor outputs, however. But less of this behind the UFO cockpit for the medium background. Buying a colorimeter isn’t worth it for gaming, but editors and content creators will likely need it for this model. At 60Hz, above, the UFO appears soft without sharp focus or clear internal detailing. 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. This means that the connectivity layout doesn’t have restrictions, so you get a full range of options with this model. The IPS panel is capable of excellent image quality, but it requires calibration first which can be a dealbreaker for some users. Around 1000:1 even following adjustments to our ‘Test Settings’. As noted earlier, AMD FreeSync makes use of Adaptive-Sync technology on a compatible monitor. The setting is listed as ‘Wait for Vertical Refresh’. The stronger overdrive settings are certainly worth exploring if you can consistently maintain a very high frame rate but still use Adaptive-Sync. It’s important to reduce blue light exposure in the hours leading up to sleep, as it’s stimulating to the body and affects sleep hormones. Lara’s skin also appeared much as it should, without the overly tanned appearance that a wider gamut would provide. Some of the deep greens weren’t as lush as they could be, nor were things like bright purple flowers and some of Lara’s ornate dresses as eye-catching as we’ve seen. When a monitor is used in this way, it is something which Nvidia refers to as ‘G-SYNC Compatible’. The overall balance to the image was good and things had a ‘rich and natural’ appearance. 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. TN models show obvious saturation shifts vertically. Nabízí kontrastní poměr 1000:1, jas 400 cd/m 2 … Instead, this model has a smooth gunmetal finish which keeps up with the brand’s premium lineage and reputation. The monitor provided a rich and natural appearance to, We also observed various episodes of the animated TV series, The monitor produced most shades here quite faithfully, accounting for the natural differences related to emissive vs. non-emissive objects noted above. ‘Extreme’ in particular showed very strong and eye-catching overshoot. There are again varying degrees of trailing behind the object due to pixel response weaknesses. The monitor offers fairly comprehensive sRGB coverage (99%), with a very small amount of under-coverage. The base takes up a lot of space, but it provides superb flexibility to the monitor. The strong consistency was also very evident when considering Lara’s glowing and all-too-perfect complexion. So better than some IPS-type models, weaker than others but very much as specified. The luminance uniformity was quite good. It’s something that will be more pronounced if you’re 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. This is Alienware’s latest, fastest gaming monitor in the market as it is a 1080p IPS LCD monitor that has 240Hz refresh rate with 1ms GtG response time.What 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). Or obvious flashes of pink that shift along with slight head movement.The red block appeared a fairly rich red throughout. 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. Greater flexibility offered in the OSD than the ‘Standard’ setting. At 240Hz, above, the UFOs again appear more sharply focused again with clearer internal detailing. The screen surface imparted a bit of graininess to lighter content, so it wasn’t as smooth as it could’ve been. And twice as much when compared to 120Hz or 1.67 times as much compared to 144Hz. This reference screen shows no noticeable ‘powdery’ trailing but a little overshoot instead.With ‘VRR off’ the ‘Super Fast’ and moreover ‘Extreme’ settings show strong overshoot in the form of bright ‘halo’ trailing. When we say obvious, it’s very subjective – sensitive users can certainly notice such things and it can be very nice indeed having them gone. And twice as much when compared to 120Hz or 1.67 times as much compared to 144Hz. 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.The colour reproduction was a relative strength of this monitor and a good step up from competing models with other panel types. We refer to these as ‘interlace pattern artifacts’ but some users refer to them as ‘inversion artifacts’ and others as ‘scan lines’. They often catch the eye due to their dynamic nature, on models where they manifest themselves in this way. But they were still closer to the ‘vibrant’ vs. ‘washed out’ end of the spectrum in our view. The monitor is also listed as such on Nvidia’s website. The stronger overdrive settings are certainly worth exploring if you can consistently maintain a very high frame rate but still use Adaptive-Sync. Colour reproductionColour gamutThe colour gamut of the AW2521HF (red triangle) was compared with the sRGB reference colour space (green triangle), as shown in the image below. Timestamps: Features & Aesthetics Contrast Colour reproduction Responsiveness (General) Responsiveness (Adaptive-Sync) ConclusionFor those who play a variety of games, some competitive and some casual, having a screen that offers a 240Hz refresh rate and good colour quality can be very attractive. The Dell Alienware supports a variable refresh rate range of 48 – 240Hz. Details can be found in this post. There were no clear flashes of saturated red, orange or green or shifts between these with a bit of head movement. Some users prefer to leave VSync enabled but use a frame rate limiter set a few frames below the maximum supported (e.g. This figure is influenced both by the element of input lag you ‘see’ (pixel responsiveness) and the element you ‘feel’ (signal delay). So things didn’t have a ‘banded’ or ‘blocky’ appearance as you’d see if gamma was far too low. Around 1000:1 even following adjustments to our ‘Test Settings’. Luminance uniformity tableThe luminance uniformity was quite good. Whilst both elements are important, eye movement is usually the dominant factor on modern monitors. If you’re intending to use the monitor with the Xbox Series X or Xbox Series S, be aware that a small settings tweak needs to be made on the Xbox to ensure 120Hz is selectable. We again consider ‘Fast’ or ‘Super Fast’ to be optimal – ‘Fast’ becomes the clear winner with ‘VRR off’, though. 25-inch 240Hz gaming monitors are a hot property right now and no manufacturer wants to be left out. Adaptive-Sync also worked well on both our AMD and Nvidia GPU to get rid of tearing and stuttering. This figure is influenced both by the element of input lag you ‘see’ (pixel responsiveness) and the element you ‘feel’ (signal delay). The consistency is also very good in most cases, superior to VA models and far superior to TN models (references here). With ‘VRR off’ the ‘Super Fast’ and moreover ‘Extreme’ settings show strong overshoot in the form of bright ‘halo’ trailing. This worked exactly as it’s designed to, removing tearing and stuttering by ensuring the refresh rate stuck to a multiple of the frame rate. We observed some faint vertical static interlace patterns at ~60Hz and below, but these were not particularly obtrusive. On TN models you have things looking far too masked higher up the screen due to high perceived gamma. This indicates that the monitor has been specifically tested by Nvidia and passes specific quality checks. The monitor was tested at 60Hz (directly below), 144Hz and 240Hz using all available ‘Response Time’ settings; ‘Fast’, ‘Super Fast’ and ‘Extreme’. Size class of the display as declared by the manufacturer. Nonetheless, we wouldn’t describe the atmosphere as poor in an appropriately well-lit room either. 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 numbered ‘Game’ presets could also be used as a base as they offer the same flexibility. Magazine şi preÅ£uri - Monitoare Dell Alienware AW2518HF de la 0,00 RON! Using this method, we calculated 2.63ms (under 2/3rds of a frame at 240Hz) of input lag. Further information plus an alternative way to support our work can be found on this page. With our ‘Test Settings’ we recorded a perfectly respectable 1063:1. The Dell Alienware AW2521HF 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. ‘Extreme’ in particular showed very strong and eye-catching overshoot. It requires huge visual sacrifices and very specific content to be shown on the screen. Depending on angle, the glow may take on a subtle cool-silver appearance or slightly warm green hue. 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. We stuck with the ‘Fast’ setting for the subjective testing below. If you activate the ‘Frame Counter’ in the ‘Game Setting’ section of 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. Additional testing was performed using an AMD Radeon 580 and using HDMI, although observations for this table didn’t significantly vary between GPUs or inputs. With some more noticeable ‘halo’ trailing by about 80fps (80Hz). Dark areas with just a few point sources of light illuminating are common on this title, including dark tombs and passageways. The segments are now quite distinct. Less pronounced than you’d see on TN or VA models. There is some central ‘sagging’ with an average ‘2.1’ gamma – a bit below the ‘2.2’ target, slightly brightening up some shades but nothing dramatic by any means. Découvrez les avis des clients Fnac sur Ecran PC Gaming Alienware AW2521HF 24.5" Full HD Côté obscure de la lune. It requires huge visual sacrifices and very specific content to be shown on the screen. Responsiveness in games and moviesOn Battlefield V the monitor provided a very fluid experience, where the frame rate kept pace with the 240Hz refresh rate. The image appears ‘rich and natural’ overall, with good variety. Above this dropdown list there’s a toggle for ‘Radeon Enhanced Sync’. And the lack of tearing and stuttering was very nice indeed, if you’re sensitive to such things. 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. This title offered suitable graphics options to test the full gamut of refresh rates supported by the monitor. This yielded a 394 cd/m² luminance adjustment range with a good bright maximum and dim minimum. This indicates that the monitor has been specifically tested by Nvidia and passes specific quality checks.
