We wont be going into this in detail as its a GPU feature rather than a monitor feature. AMD FreeSync is a variable refresh rate technology, an AMD-specific alternative to Nvidia G-SYNC. 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. Colour gamut Use the code 'SAVE350' to get $350 more off. For 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. And this monitor put in a very respectable performance in that respect. If you want 1080p and best motion is the xl2566k. //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. In this case appropriate richness and saturation was maintained throughout. Many of the presets make further adjustments, such as FPS, MOBA/RTS, RPG and SPORTS adding a sharpness filter which cant be disabled or counteracted effectively in the OSD aside from by selecting a different preset. Erfahren Sie, wie Sie einen Diagnosetest durchfhren, um Hardwareprobleme mit Dell Monitoren zu diagnostizieren. The refresh rate was set to 240Hz in Windows, although this didnt significantly affect the values or observations on this table. 25" Dell Alienware AW2521HF 2020 1920 x 1080 2.9ms 240Hz $ 419. In our view the price is also very reasonable and highly competitive given whats on offer. Some shades, such as cerulean (2) and lilac (8), appear somewhat undersaturated. Note that 120Hz is listed as a PC resolution, rather than in the Ultra HD, HD, SD list. The Fast setting only showed a relatively small amount of this, whilst the Super Fast and Extreme settings ramped this up. 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. This indicates that the monitor has been specifically tested by Nvidia and passes specific quality checks. Depending on angle, the glow may take on a subtle cool-silver appearance or slightly warm green hue. There is various degrees of trailing behind the UFOs due to pixel response time weaknesses. Contrast 237fps) instead, avoiding any VSync latency penalty at frame rates near the ceiling of operation or tearing from frame rates rising above the refresh rate. It includes blended grey height markers on the inside of the stand neck, from 1 to 8 with each number approximately 2cm apart. This indicates a low viewing angle dependency to the gamma curve of the monitor, typical for an IPS-type panel. Shop the Dell Alienware m17 Gaming Laptop featuring Ryzen 6000 series processors, . That means that if the game is running between 48fps and 240fps, the monitor will adjust its refresh rate to match. Reasonable contrast, in-line with expectation, strong gamma consistency and a pleasing luminance adjustment range For SDR gaming, we played a few hours of Tomb Raider. From the side the screen itself is quite slim ~16mm (0.63 inches) at thinnest point, lumping out centrally where the stand attaches. The 240Hz refresh rate also allows even division of 24fps, 30fps and 60fps which reduces juddering for such content the lack of overshoot at 240Hz worked nicely as well. Black highlights indicate the highest white luminance, lowest black luminance and highest contrast ratio recorded. 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. The slight caveat to LFC is that theres a very brief stutter when it activates or deactivates. 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. Video review The final column includes a reference screen, the Acer XN253Q X which is a very fast 240Hz TN model with well-tuned pixel overdrive. However; the Gain controls required different adjustments. The contrast performance was much as we were expecting. 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. I have also went into Nvidia control panel and set the following. Its possible newer Nvidia GPUs, including their RTX series, support this expanded range or it may have just been misreported on the website. No saturation losses towards the bottom or edges as youd see from other panel types. We also tested movie content, which was much more limited in frame rate (generally 24fps, 30fps or 60fps). Our RX 580 is far from a powerhouse of a graphics card, so maintaining 240fps was very tricky. The contrast gradients were displayed well, with distinct brightness steps in most cases. The setting is listed as Wait for Vertical Refresh. Where possible, the monitor dynamically adjusts its refresh rate so that it matches the frame rate being outputted by the GPU. Main: Roasted chicken with roasted potatoes and green beans. Brightness 200cd/m 2 - 56. AMD FreeSync is a variable refresh rate technology, an AMD-specific alternative to Nvidia G-SYNC. Though neither of the two support HDR, both exhibit an impressively high SDR peak brightness level that exceed 400 nits. Out of the box the monitor produced an image with a clear cool tint, but with strong consistency and pleasing shade variety. Luminance uniformity map 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. Donations are also greatly appreciated. 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. 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. We didnt readily observe either artifact type at high or relatively high refresh rates (100Hz+). Rather than simply reflecting the pixel response elements. TN models show obvious saturation shifts vertically. As with AMD FreeSync this technology worked very well, although there was a momentary stutter when it activated or deactivated. It has exceptional motion handling and low input lag, whether you play at its maximum 240Hz refresh rate or 60Hz. The red block appeared a fairly rich red throughout. Apart from the power button, which contains a built-in LED ring, the only lighting comes from the back of the stand, which reflects off your wall for some nice subtle bias lighting. Sensitivity to such things varies, however. Dips below this were common. Note that 120Hz is listed as a PC resolution, rather than in the Ultra HD, HD, SD list. Select Manage 3D Settings under 3D Settings. Luckily, two of the USB ports and the headphone jack are under the panel edge in a more accessible position. 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. The following observations were made from a normal viewing position, eyes ~70cm from the screen. Including at some regions of TN and to a lesser extent VA screens due to the perceived gamma shifts as we described earlier using Battlefield V as an example. 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. Buy from Amazon The technology worked well and offered a very similar experience to AMD FreeSync. And more of a futuristic prop from a sci-fi movie kind of way. Youll see the same element on an Alienware gaming PC which we currently have in the lab. Compare prices on Alienware AW2521HF 25" Gaming Full HD IPS 240Hz Monitors. As the frame rate dropped we noticed an increase in overshoot. But less of this behind the UFO cockpit for the medium background. TN models show obvious saturation shifts vertically. The greyscale gradient appeared smooth without obvious banding or dithering. The environments looked in-place, with good variety and some good earthy browns and rich green shades. 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. This reference screen shows no noticeable powdery trailing but a little overshoot instead. 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. 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. 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. 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. 237fps) instead, avoiding any VSync latency penalty at frame rates near the ceiling of operation or tearing from frame rates rising above the refresh rate. This feature is used regardless of VSync setting, so its only above the ceiling of operation where the VSync setting makes a difference. 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. With the AW2521HF, you need to connect the monitor up via DisplayPort and enable FreeSync in the Game section of the OSD. Intended as a Low Blue Light (LBL) setting, but very ineffective. For 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. fps got much better BUT .1% and 1% lows are so much better than any CPU on market while being clocked slower than 5800x 200-400mhz that it makes no sense to normal consumer why the hell is it so good when it is simply extra L3$ reducing amount of times CPU has to access latency included slow RAM which causes that stuttering or hitching Luminance uniformity table No saturation losses towards the bottom or edges as youd see from other panel types. The technology worked well and offered a very similar experience to AMD FreeSync. Where possible, youll be redirected to your nearest store. Adaptive-Sync also worked well on both our AMD and Nvidia GPU to get rid of tearing and stuttering. Dips below this were common. 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. Strong colour consistency and slight extension beyond sRGB, giving a rich and natural image without potentially overbearing saturation Considering a broader range of pixel transitions, all Response Time settings were fairly similar at 240Hz with Adaptive-Sync in use (VRR on). On some monitors, particularly but not exclusively those with high refresh rates, interlace patterns can be seen during certain transitions. IPS glow also came with the territory. 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. R Gain= 100% Alienware Tenkeyless Gaming Keyboard - AW420K. RtN on 03/03/2023 - 16:22 Performance on the black level test was good overall. Plus a bit of overextension, in the green to red region. This is exactly what the Dell Alienware AW2521HF delivered. 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 numbered Game presets could also be used as a base as they offer the same flexibility. Candy apple red appeared with a bit of an orange-red tone due to extension in the red to green edge of the gamut. Este artigo apresenta informações gerais sobre os monitores Dell Gaming e Alienware. FreeSync requires a compatible AMD GPU such as the Radeon RX 580 used in our test system. Submit Search. The strong colour consistency ensured shades maintained appropriate richness throughout the screen, without the saturation shifts youd see on VA or TN models. I've tried changing the response time from Extreme to Fast or Super Fast, but when I do that the blur get's even worse. The top and side bezels are slender with a dual-stage design, including a panel border thats flush with the rest of the screen and a slim hard plastic outer component. Theres a customisable power indicator LED towards the bottom right, part of the AlienFX RGB lighting system. The purple block appeared a violet shade throughout, with a bit more of a pink hue towards the bottom and extreme side edges. A medium matte anti-glare screen surface is used, as explored shortly. There is one thing that i have noticed on this monitor, when you use the superfast response time, the image itself looks better (colors etc. Perceived blur (pursuit photography) Things arent quite up to the level of the TN reference, but there are no particularly pronounced weaknesses either. Plus a bit of overextension, in the green to red region. This configures it globally, but if you wish to configure it for individual games click Game Graphics towards the top right. There is a list of GPUs which support the technology here, with the expectation that future AMD GPUs will support the feature too. But this is due more to uniformity on our sample than viewing angle behaviour. The OSD (On Screen Display) is controlled by a joystick and pressable buttons running down the right side of the monitor, as viewed from the rear. The purple block appeared a violet shade throughout, with a bit more of a pink hue towards the bottom and extreme side edges. With VRR off the Super Fast and moreover Extreme settings show strong overshoot in the form of bright halo trailing. 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. Given the intended uses for monitor, inter-unit variation and decent performance following OSD tweaking alone we will not be using any. I guess the 80,000,000:1 dynamic contrast ratio really works well on this monitor. It only works up to 240 Hz, but it really makes a visible improvement to motion resolution. 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. There is also a 3.5mm jack for analog audio, but there are no speakers with this model. Unless youre frequently passing this boundary its not something youre likely to notice or care about, though. 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. Screen surface imparts a bit of graininess to lighter content 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. Also while scrolling down webpages it looks really blurry. When a monitor is used in this way, it is something which Nvidia refers to as G-SYNC Compatible. When you go to custom color you have 4 options that you can modify: Gain, Offset, Hue, Saturation. On TN models you have things looking far too masked higher up the screen due to high perceived gamma. Gradients showed no visible banding, viewing angles are great thanks to the IPS panel, and gamma followed the 2.2 curve closely, deviating just a tad on the brighter end of the spectrum. Its something were sensitive to, as long-time readers of our website will be well aware. The perceived blur due to eye movement was also greatly reduced, much as demonstrated with the pursuit photos earlier on. Using this method, we calculated, 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. But far from poor. This, coupled with the inclusion of a flipped version of the shade sheet, allows both accuracy and colour consistency to be visually assessed. It requires huge visual sacrifices and very specific content to be shown on the screen. There was slight extra yellowing at the bottom of the screen but nothing extreme. Some game engines will also show stuttering (or hitching) for various other reasons which wont be eliminated by the technology. 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. 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 video below shows the Lagom text test, a mixed desktop background, game scene and dark desktop background from a variety of viewing angles. At a basic level, a mismatch between the frame rate and refresh rate can cause stuttering (VSync on) or tearing and juddering (VSync off). Find many great new & used options and get the best deals for Alienware 25" Full HD 240HZ HDMI DP FreeSync G-Sync LED Gaming Monitor-AW2521HF at the best online prices at eBay! So better than some IPS-type models, weaker than others but very much as specified. But if you max the backlight with G-Sync, its 48% dimmer with ULMB, so the change isnt constant. 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.
