Saiba como executar um teste de diagnstico para diagnosticar problemas de hardware com os monitores Dell. [CDATA[ Or obvious flashes of pink that shift along with slight head movement. With the AW2521HF, you need to connect the monitor up via DisplayPort and enable FreeSync in the Game section of the OSD. This provides effective blue light reduction and can easily be assigned to a numbered Game preset for easy activation and deactivation. 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. With some more noticeable halo trailing by about 80fps (80Hz). White levels were on point, meaning highlight detail will appear as intended. . To test the performance of monitors, I run a DisplayCal verification using an X-Rite i1Display Pro colorimeter, alongside a few by-eye tests using Lagom's LCD test patterns. The input panel is recessed deeply underneath, so much so that cables with large connectors will be difficult to use. 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. We'll assume you're ok with this, but you can opt-out if you wish. The red block appeared a fairly rich red throughout. Conclusion Strong consistency due to IPS-type panel, without the perceived gamma and saturation shifts associated with TN or VA panels. The ~1000:1 static contrast being somewhat limiting in that respect. As an Amazon Associate I earn from qualifying purchases made using the below link. 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 stand has a penguin-foot design with flattened feet and a wide neck piece. Below you can see how things appear with refresh rate ramped up to 240Hz. Luminance uniformity map This gives the monitor the potential to output most shades within the sRGB colour space, with just a touch of extra vibrancy. 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. The gamma is slightly below target, brightening up some shades just a little, but the overall image balance is very respectable. You can also try the ULMB strobing backlight feature for even clearer motion, though it only works when G-Sync is off and the refresh rate is set to 240Hz and comes with some artifacts behind moving objects. The new generation TN panels such as the Acer XN253Q X dont show any noticeable weaknesses in terms of powdery trailing and offer impressively rapid pixel responses across the board. It is, however, extremely accurate within that sRGB space. The image below is a macro photograph taken on Notepad with ClearType disabled. The final column includes a reference screen, the Acer XN253Q X which is a very fast 240Hz TN model with well-tuned pixel overdrive. 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 IPS-type panel of the Dell Alienware certainly provided a key contrast advantage over VA and TN models, though. With some more noticeable halo trailing by about 80fps (80Hz). The representation of shades in this image depends on the camera and your own screen, its not designed to show exactly how the shades appear in person. Most users will probably wish to enable VSync when using FreeSync to ensure that they dont get any tearing. Best Settings and Options Guide; Apex Legends. 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. Colour reproduction Brighter elements stood out well against darker surroundings and the detail levels for most of the screen were appropriate. We know life quality is important, which is why we work to provide you with the best gaming monitor 240hz. 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. The brightest point recorded was quadrant 5 in the centre of the screen (168.2 cd/m). This gave an unbalanced image with clear green tint, without achieving its key goal. Strong glare-handling is provided due to significant diffusion of ambient light. We created out own LBL setting as described below. The monitor didnt put form over function, either, and was solidly built with good ergonomic flexibility and VESA mounting options. On the panels top edge is an ambient light sensor. When you open up Nvidia Control Panel, you should then see Set up G-SYNC listed in the Display section. Given the intended uses for monitor, inter-unit variation and decent performance following OSD tweaking alone we will not be using any. Less pronounced than youd see on TN or VA models. Colour reproduction This diffusion also affects light emitted from the monitor, with a negative impact on the clarity and vibrancy potential of the screen. From the side the screen itself is quite slim ~16mm (0.63 inches) at thinnest point, lumping out centrally where the stand attaches. Unless youre frequently passing this boundary its not something youre likely to notice or care about, though. There is a list of GPUs which support the technology here, with the expectation that future AMD GPUs will support the feature too. 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. FreeSync the technology and activating it The main feature from the front, as usual, is the screen face. Best Overdrive Setting: Off: Black Frame Insertion (BFI) Yes: Dark Overshoot Error: 0.0%: . FreeSync the experience Contrast 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. 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. Most users will probably wish to enable VSync when using FreeSync to ensure that they dont get any tearing. While cinematic first-person games really benefit from large, high-res displays, online multiplayer games like Overwatch and Counter-Strike: Global Offensive really shine with high refresh rates. And not blended enough (blocky or banded) lower down due to low perceived gamma. And that was its excellent gamma consistency. This reflects a moderate amount of perceived blur due to eye movement and is something shared with the reference screen. To configure VSync, open AMD Radeon Software. Today's best Alienware 25 Gaming Monitor AW2521H deals, We check over 250 million products every day for the best prices, Alienware 25 Gaming Monitor AW2521H: Price Comparison. The SpyderX Elite was also used to analyse variation in the colour temperature (white point) for the same 9 quadrants. Some shades brightened up just slightly due to gamma handling, but not by a huge amount. No saturation losses towards the bottom or edges as youd see from other panel types. So things didnt have a banded or blocky appearance as youd see if gamma was far too low. The numbered Game presets could also be used as a base as they offer the same flexibility. G-Sync worked perfectly as we often hit the 360 Hz maximum, thanks to the GeForce RTX 3090 graphics card in our Alienware gaming PC. 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. 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 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. Features & Aesthetics The competitive advantage of the 240Hz refresh rate was irrelevant on this title, although we still noticed an edge in connected feel and perceived blur on the rare occasions frame rate got up high enough. Greater flexibility offered in the OSD than the Standard setting. This figure is influenced both by the element of input lag you see (pixel responsiveness) and the element you feel (signal delay). The optimal setting here depends on your own preferences in this respect. 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 third and fourth blocks were slightly fainter than they should be, although still distinguishable. Most shades appeared very consistent indeed, with any slight deviation due more to uniformity than any viewing angle related weakness. The Lagom text appeared a blended grey throughout, with a slight red hue to the striping of the text. The colour temperature is warmer by default but the blue channel remained strong on our unit and green channel very strong. More pronounced at the left side due to the glow taking on a cool tint rather than the subtler warmer tint towards the right side. And that was its excellent gamma consistency. With VRR off the Super Fast and moreover Extreme settings show strong overshoot in the form of bright halo trailing. The butter-smooth, blur-free motion of fast panels like the AW2521H is something you have to experience to understand, and it gives you this sense of control that 60Hz doesn't quite hit. Laras skin also appeared much as it should, without the overly tanned appearance that a wider gamut would provide. This feature is used regardless of VSync setting, so its only above the ceiling of operation where the VSync setting makes a difference. Not to the extent seen on models with a more generous colour gamut, but enough to stand out and have the intended look overall. The stand has a penguin-foot design with flattened feet and a wide neck piece. Press OK, then turn the monitor off then on again so that it re-establishes connection the technology should now be active. The refresh rate was put to very good use overall; fairly strong pixel responsiveness, low input lag and no noticeable overshoot.

At 240Hz, above, the UFOs again appear more sharply focused again with clearer internal detailing. The luminance of each quadrant was measured and compared to the brightest measured quadrant. There was more pop and sharper detail in both highlight and shadow areas of the image. Assume any setting not mentioned, including Contrast, was left at default. But there wasnt a strong coarse graininess nor a strong smeary appearance, either. VRR off did not significantly affect the pixel response behaviour at this refresh rate. The IPS screen provides decent viewing angles with little color shift or light reduction when viewed up to 45 degrees off center. That means shades just above the darkest black will appear too dark, obscuring fine details in shadows not ideal for competitive gaming, which could mean missing a stealthy opponent. But being able to change the power LED colour to suit your mood is a nice little touch. Gamboge (23) verged too much on a mustard yellow without a suitably warm golden hue, too. LG 27GR95QE MonitorsUnboxed Review. 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. 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 image below shows how things look with refresh rate bumped up to 144Hz. But far from poor. The SpyderX Elite was used to assess the uniformity of lighter shades, represented by 9 equidistant white quadrants. All but the final pattern was distinct from the background, with the final pattern faintly visible although a bit fainter than it could be. The AW2521HFL is also available, differing only due to this dark grey shade being replaced with a much lighter Lunar Light shade. Dips below this were common. For gaming, this monitor is the best I've used. The full capabilities of the monitor including 1920 x 1080 @240Hz and Adaptive-Sync for AMD FreeSync can be leveraged via DP 1.2 or HDMI 2.0. Colour gamut 'Test Settings' The Alienware AW2721D is a new high-end 27-inch 1440p monitor, giving us our first look at the combination of a 240Hz refresh rate and IPS technology at this resolution. Dips below this were common. IPS glow also came with the territory. Every player has a different notion about the ideal setting for PC . 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 contrast gradients were displayed well, with distinct brightness steps in most cases. The Lagom tests for contrast allow specific weaknesses in contrast performance to be identified. The front-face of this is matte black plastic, with a satin-finish Dark Side of the Moon (dark grey) plastic upper surface that continues at the rear of the stand. 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. What can we help you to find. The monitor can also be set to 120Hz although not documented in this testing, results were very much comparable to 144Hz. We refer to these as interlace pattern artifacts but some users refer to them as inversion artifacts and others as scan lines.
