. Following some tweaking in the OSD, things were brought more in-line with our target white point. The Dell Alienware supports a variable refresh rate range of 48 240Hz. This configures it globally, but if you wish to configure it for individual games click Game Graphics towards the top right. In saturation I lowered Red to 48% and Yellow to 34% and left the others at 50%. Given the intended uses for monitor, inter-unit variation and decent performance following OSD tweaking alone we will not be using any. You need to make sure FreeSync is set to On in the Game section of the OSD. 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. The responsiveness of the monitor was also quite impressive which is a good thing given that its a key focus of 240Hz models like this. The strong colour consistency ensured shades maintained appropriate richness throughout the screen, without the saturation shifts youd see on VA or TN models. Without FreeSync active and VSync disabled, youd get obvious tearing from the lack of synchronisation between frame and refresh rate. Negatives Game 1 2.1 7942K Similar to above, as with Game 2 and Game 3.
Alienware AW2521H Review - IGN At least on our unit, where the default colour temperature was far too high. 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. Features and aesthetics The input panel is recessed deeply underneath, so much so that cables with large connectors will be difficult to use. As with AMD FreeSync this technology worked very well, although there was a momentary stutter when it activated or deactivated. 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. This indicates that the monitor has been specifically tested by Nvidia and passes specific quality checks. The deviation between each quadrant and the quadrant closest to the 6500K (D65) daylight white point target was analysed and a DeltaE value assigned. This more pronounced powdery trailing was still less pronounced than some of the weaknesses weve observed observe for similar transitions on many 240Hz TN models, including the predecessor to this model (AW2518H/HF), ViewSonic XG2530 and AOC AG251FG. This requires that the frame rate comfortably exceeds the refresh rate, not just peaks slightly above it. Screen Size: 25 inches. This gives an excellent connected feel, which describes the precision and fluidity felt when interacting with your character and the game world. Further information on supporting our work. Using VRR improved pixel response behaviour for very high refresh rates, too, allowing the Extreme overdrive setting to be used without strong overshoot. G Gain= 88% Slight deviation from preferred 2.2 gamma, without gamma settings in OSD. The pastel shades of this movie were suitably varied and muted, whilst vibrant shades such as neon reds and greens appeared fairly eye-catching. The depth of the dark shades and overall atmosphere created was certainly not as impressive as on models with much stronger static contrast. If you play as much Tomb Raider as you do Overwatch, you'll probably find this monitor a bit lacking for games in the former category.
dual screen gaming laptops - Search 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. With respectable graphics settings and more intense action it wasnt uncommon to see dips below 100fps, perhaps closer to 60fps on average. Theres a customisable power indicator LED towards the bottom right, part of the AlienFX RGB lighting system. Negatives Input lag sits at 3ms, so there is no need to worry about delays or de-synced instances. Youd therefore select either the third or fourth option in the list, shown in the image below. Compared to at 60Hz, or indeed a 60Hz monitor, youre getting up to 4 times as much visual information pumped out every second. As things dipped even further, below the 48fps (48Hz) floor of operation for FreeSync, the monitor employed LFC (Low Framerate Compensation). This worked exactly as its designed to, removing tearing and stuttering by ensuring the refresh rate stuck to a multiple of the frame rate. As an Amazon Associate I earn from qualifying purchases made using the below link. 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. This is a good practical speed to take such photographs at, highlighting both elements of perceived blur nicely. This was by no means extreme and not everyone will notice it many Adaptive-Sync models have much stronger overshoot than this following such refresh rate drops, in fact.
Dell Alienware AW2521HF Review - RTINGS.com With the AW2521HF, you need to connect the monitor up via DisplayPort and enable FreeSync in the Game section of the OSD. The panel at the rear includes DisplayPort 1.2, two HDMI 2.0 slots, and four USB 3.0 ports for peripherals. 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. On some monitors, particularly but not exclusively those with high refresh rates, interlace patterns can be seen during certain transitions. Contrast 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. As the frame rate dropped we noticed an increase in overshoot. The numbered Game presets gave a significantly higher white point and somewhat stronger green channel with everything set to 100% than under Custom Color. There was borderline significant deviation above the central region (DeltaE 3.0), with no significant deviation recorded elsewhere. I was disappointed to find that it only offered 20 colors, though, none of which were plain white (my preferred bias lighting color). Performance on the black level test was good overall. Pixel response behaviour was similar under the Fast setting whether Adaptive-Sync was active or not both in this test and more broadly. Such an option does usually exist it may be called sync every frame or something along those lines rather than simply VSync. The setting is found in Manage 3D settings under Vertical sync, where the final option (Fast) is equivalent to AMDs Enhanced Sync setting. Shadow of the Tomb Raider told a similar story. With the AW2521HF, you need to connect the monitor up via DisplayPort and enable FreeSync in the Game section of the OSD. But not the strong saturation levels youd see from models with more generous gamuts. The Fast setting was quite close to the reference here, with slightly stronger but still by no means extreme overshoot.

Visit our best FPS gaming monitors buyer's guide for more information and the best deals available. 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. 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. AlienWare AW2518HF. 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. We also observed various episodes of the animated TV series Futurama. The first couple of blocks blended into the background well, which is usual for a monitor tracking the 2.2 gamma curve correctly. Input lag The brightest point recorded was quadrant 5 in the centre of the screen (168.2 cd/m).
27" Gigabyte AORUS FI27Q 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. Brightness 120cd/m 2 - 25. 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. Some game engines will also show stuttering (or hitching) for various other reasons which wont be eliminated by the technology. 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. At 60Hz we measured a slightly higher but still reasonable 6.47ms. This figure is influenced both by the element of input lag you see (pixel responsiveness) and the element you feel (signal delay). Buy from Amazon The following observations were made from a normal viewing position, eyes ~70cm from the screen. This requires that the frame rate comfortably exceeds the refresh rate, not just peaks slightly above it. The Dell Alienware supports a variable refresh rate range of 48 240Hz. 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. Although not nearly as pronounced or obvious as stepping up from 60Hz to 144Hz (or even 120Hz). This is the default expected by modern operating systems such as Microsoft Windows and Apples MacOS. The remaining blocks were displayed appropriately with good steps up in brightness. Note that we have no way to accurately measure input lag with Adaptive-Sync active in a variable refresh rate and frame rate environment. Either way, where the frame rate drops below the floor of operation a frame to refresh multiplication technology (what AMD refers to as LFC) kicked in to keep tearing and stuttering at bay. HDR processing cost us about 20 fps, but the game still hit 360 fps on occasion. Viewing angles The stronger overdrive settings are certainly worth exploring if you can consistently maintain a very high frame rate but still use Adaptive-Sync. There were no clear flashes of saturated red, orange or green or shifts between these with a bit of head movement. We put it through a battery of tests to see how it stacks up. On the panels top edge is an ambient light sensor. Laras skin also appeared much as it should, without the overly tanned appearance that a wider gamut would provide. The purple block appeared a violet shade throughout, with a bit more of a pink hue towards the bottom and extreme side edges. The Fast setting only showed a relatively small amount of this, whilst the Super Fast and Extreme settings ramped this up. Ensure the Enable G-SYNC, G-SYNC Compatible checkbox and Enable settings for the selected display model is checked as shown below. Create an account to follow your favorite communities and start taking part in conversations. It cant compensate for other interruptions to smooth game play, for example network latency or insufficient system memory. 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. The red block appeared a fairly rich red throughout. 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. Earthy browns appeared with good neutrality a little extra richness and a slight orange-red push in places but not the sort of stronger red hue that a wider gamut would provide. Integrated cable routing allows for easy adaptability, and Cherry MX Red switches provide consistent high-performance gaming. Positives 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. Over 30 repeat readings were taken to help maximise accuracy. Future US, Inc. Full 7th Floor, 130 West 42nd Street, [CDATA[ In the three Game modes, color saturation controls are available, but there are no gamma or grayscale adjustments. This provides effective blue light reduction and can easily be assigned to a numbered Game preset for easy activation and deactivation. There are some further customisable AlienFX RGB LED features an alien motif towards the top left and a large oval running along the inside of the stand neck. We prefer stronger RGB LEDs at the rear, producing a strong glow around the monitor that can help enhance perceived contrast. IPS glow also featured, but appropriate room lighting took the edge off this. This was by no means extreme and not everyone will notice it many Adaptive-Sync models have much stronger overshoot than this following such refresh rate drops, in fact. Note that wavy patterns surrounding some UFOs in the background are slight image retention. The responsiveness of the monitor was also quite impressive which is a good thing given that its a key focus of 240Hz models like this. It was free from alternation between deeper purple and a very strong pink hue that youd see on VA and moreover VA models. There were some significant differences when Adaptive-Sync was disabled using the Super Fast and Extreme settings these are documented as VRR off (Variable Refresh Rate off). 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. When viewing the figures in this table, note that for most PC users 6500K for white point and 2.2 for gamma are good targets to aim for. 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. You get a countdown timer, an FPS . The colour reproduction was a relative strength of this monitor and a good step up from competing models with other panel types. 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. Preset Mode Gamma (central average) White point (kelvins) Notes Standard (Factory Defaults) 2.1 7948K An obvious cool (blue) almost icy-looking tint due to very high colour temperature. Considering video content more broadly, including streamed and heavily compressed content, there was suitable masking of compression artifacts. 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. But there wasnt a strong coarse graininess nor a strong smeary appearance, either. 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. Some users prefer to leave VSync enabled but use a frame rate limiter set a few frames below the maximum supported (e.g. Below you can see how things appear with refresh rate ramped up to 240Hz. The third and fourth blocks were slightly fainter than they should be, although still distinguishable. This is an alternative to VSync which allows the frame rate to rise above the refresh rate (no VSync latency penalty) whilst potentially keeping the experience free from tearing or juddering. A slight difference was that the floor of operation was 80Hz (80fps) on our Nvidia GPU. Motion is the most important performance metric for a 360Hz monitor, though, so the response time needs to be low to avoid ghosting. We therefore consider Fast the optimal setting at 60Hz. Things arent quite up to the level of the TN reference, but there are no particularly pronounced weaknesses either. As things dipped even further, below the 48fps (48Hz) floor of operation for FreeSync, the monitor employed LFC (Low Framerate Compensation). The ~1000:1 static contrast being somewhat limiting in that respect. With some more noticeable halo trailing by about 80fps (80Hz). The driver setting change noted in the article setting Output dynamic range to Full is the simplest method. But less of this behind the UFO cockpit for the medium background.

Lagom's response time test consists of a number of squares quickly alternating between two shades if the squares flicker, then the response time is slow for that transition, meaning you may see a trail behind moving objects. The AW2521H is not an HDR or wide gamut monitor, instead hitting about 450 nits of maximum brightness and covering 92.8% of the sRGB color space. The design of the monitor is in keeping with the Alienware aesthetics of other recent additions to the series and indeed their other peripherals and systems. Most shades appeared very consistent indeed, with any slight deviation due more to uniformity than any viewing angle related weakness. 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 segments are now quite distinct. This model is HDR 400-capable, but it can only offer minor improvements to the appearance of your compatible games and media. Some would prefer a wider gamut for extra vibrancy The monitor is also listed as such on Nvidias website. Youll have to turn off G-Sync and reduce the refresh rate to 240 Hz to use it. And not blended enough (blocky or banded) lower down due to low perceived gamma.
