The UFOs move across the screen from left to right at a frame rate matching the refresh rate of the display. 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 very low signal delay of this model also aided the ‘connected feel’, but the very high frame and refresh rate combination also helped. The setting is found in ‘Manage 3D settings’ under ‘Vertical sync’, where the final option (‘Fast’) is equivalent to AMD’s ‘Enhanced Sync’ setting. AMD FreeSync is a variable refresh rate technology, an AMD-specific alternative to Nvidia G-SYNC. The default is ‘Off, unless application specifies’ which means that VSync will only be active if you enable it within the game itself, if there is such an option. The first couple of blocks blended into the background well, which is usual for a monitor tracking the ‘2.2’ gamma curve correctly. If a game ran at 34fps, for example, the refresh rate would be 68Hz to help keep tearing and stuttering at bay. We won’t be going into this in detail as it’s a GPU feature than a monitor feature. This figure is influenced both by the element of input lag you ‘see’ (pixel responsiveness) and the element you ‘feel’ (signal delay). One of the most important concepts raised in that article is ‘perceived blur’, contributed to by the movement of your eyes as you track motion on the screen as well as pixel responsiveness. ‘IPS glow’ also featured, but appropriate room lighting took the edge off this. Lagom’s tests for viewing angle tests help explore the idea of colour consistency and viewing angle performance. The contrast gradients were displayed well, with distinct brightness steps in most cases. Rather than simply reflecting the pixel response elements.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. 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 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. The pastel shades of this movie were suitably varied and muted, whilst vibrant shades such as neon reds and greens appeared fairly eye-catching. It indicates a very low signal delay at 240Hz which even sensitive users shouldn’t find bothersome. Most users will probably wish to enable VSync when using FreeSync to ensure that they don’t get any tearing. 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 monitor performed well here, without clear shifts in saturation or colour tone. But less of this behind the UFO cockpit for the medium background. 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. Most shades appeared very consistent indeed, with any slight deviation due more to uniformity than any viewing angle related weakness. The following observations were made. Many of the presets make further adjustments, such as ‘FPS’, ‘MOBA/RTS’, ‘RPG’ and ‘SPORTS’ adding a sharpness filter which can’t be disabled or counteracted effectively in the OSD aside from by selecting a different preset. In the example of white text against a shaded backdrop, this only occurred at certain grey levels for the background, so not all dark shades would trigger it. The display is bezel-free on three sides, but you will still see thin panel borders when the display is in use. This is quite common on LBL settings as reducing the green channel negatively impacts contrast, but in this case it was rather noticeable and you were left with a warmish but very green image. 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. This reflects another significant reduction in perceived blur due to eye movement. No saturation losses towards the bottom or edges as you’d see from other panel types. At 60Hz we measured a slightly higher but still reasonable 6.47ms. The depth of the dark shades and overall atmosphere created was certainly not as impressive as on models with much stronger static contrast. Note that individual units and preferences vary, so these settings are simply a suggestion and won’t necessarily be optimal in all cases. There is a little ‘light powdery’ trailing behind the UFOs, particularly for the dark and medium backgrounds. Earthy browns appeared with good neutrality – a little extra richness but not the sort of stronger red hue that a wider gamut would provide. The monitor itself must support ‘VESA Adaptive-Sync’ for at least one of its display connectors, as this is the protocol that FreeSync uses. To maximise colour accuracy within the sRGB colour space, for colour-managed workflows, full calibration and profiling with a colorimeter or similar device is recommended. The segments are now quite distinct. The screen surface imparted a bit of graininess to lighter content, so it wasn’t as smooth as it could’ve been. They often catch the eye due to their dynamic nature, on models where they manifest themselves in this way. This displays the current refresh rate of the monitor and will reflect the frame rate if it’s within the main variable refresh rate window (e.g. It takes some practice, but at least it won’t be a struggle like with buttons that can easily be miss-pressed in the dark. And that was its excellent gamma consistency. 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 was far from a major weakness. Dacă jucați titluri concentrate cu un jucător sau non-sport, există alte opțiuni mai bune în altă parte. Adaptive-Sync support is included, allowing AMD FreeSync Premium and Nvidia’s ‘G-SYNC Compatible Mode’ to be used. There is a list of GPUs which support the technology here, with the expectation that future AMD GPUs will support the feature too. Things aren’t quite up to the level of the TN reference, but there are no particularly pronounced weaknesses either. This indicates that the monitor has been specifically tested by Nvidia and passes specific quality checks. This reflects a moderate amount of perceived blur due to eye movement and is something shared with the reference screen. At 240Hz, above, the UFOs again appear more sharply focused again with clearer internal detailing. Strong consistency due to IPS-type panel, without the perceived gamma and saturation shifts associated with TN or VA panels. 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. We again consider ‘Fast’ or ‘Super Fast’ to be optimal – ‘Fast’ becomes the clear winner with ‘VRR off’, though. Depending on angle, the glow may take on a subtle cool-silver appearance or slightly warm green hue. Percentage deviations between each quadrant and the brightest point are also given. We didn’t observe either artifact type at high or relatively high refresh rates (100Hz+). The final column includes a reference screen, the, This more pronounced ‘powdery’ trailing was still less pronounced than some of the weaknesses we’ve observed observe for similar transitions on many 240Hz TN models, including the predecessor to this model (, Given the extensive analysis above, we don’t much to add from, FreeSync requires a compatible AMD GPU such as the Radeon RX 580 used in our test system. 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. 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. Even on this title where there are lots of ‘high contrast’ transitions, with bright objects against much darker backgrounds, there was nothing that really caught the eye as a clear weakness. This indicates a low viewing angle dependency to the gamma curve of the monitor, typical for an IPS-type panel. We prefer stronger RGB LEDs at the rear, producing a strong glow around the monitor that can help enhance perceived contrast. The screenshot below is for a different model, but the settings and layout of the page are the same. And not blended enough (‘blocky’ or banded) lower down due to low perceived gamma. When you open up Nvidia Control Panel, you should then see ‘Set up G-SYNC’ listed in the ‘Display’ section. Some game engines will also show stuttering (or ‘hitching’) for various other reasons which won’t be eliminated by the technology. Some shades, such as cerulean (2) and lilac (8), appear somewhat undersaturated. At a basic level, a mismatch between the frame rate and refresh rate can cause stuttering (VSync on) or tearing and juddering (VSync off). The monitor offers fairly comprehensive sRGB coverage (99%), with a very small amount of under-coverage. This reflects a significant reduction in perceived blur due to eye movement. A futuristic ‘sci-fi prop’ look which some will find quite endearing. It blooms out more noticeably from sharper viewing angles, with the hue varying depending on angle – this is shown in the viewing angles video later on. Monitor boltok, képek. To maximise colour accuracy within the sRGB colour space, for colour-managed workflows, full calibration and profiling with a colorimeter or similar device is recommended. Lara’s skin also appeared much as it should, without the overly tanned appearance that a wider gamut would provide. Even on this title where there are lots of ‘high contrast’ transitions, with bright objects against much darker backgrounds, there was nothing that really caught the eye as a clear weakness. The setting is found in ‘Manage 3D settings’ under ‘Vertical sync’, where the final option (‘Fast’) is equivalent to AMD’s ‘Enhanced Sync’ setting. 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. 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. So things didn’t have a ‘banded’ or ‘blocky’ appearance as you’d see if gamma was far too low. But this is due more to uniformity on our sample than viewing angle behaviour. The remaining presets make specific adjustments to those and can’t be manually altered. The IPS-type panel of the Dell Alienware certainly provided a key contrast advantage over VA and TN models, though. We’d describe the image as ‘rich and natural’, with a richness maintained throughout the screen thanks to the strong colour-consistency. This characteristic makes the monitor a practical choice since you don’t need to stick to one GPU brand for the rest of its lifespan. Around 1000:1 even following adjustments to our ‘Test Settings’. The new generation TN panels such as the Acer XN253Q X don’t show any noticeable weaknesses in terms of ‘powdery’ trailing and offer impressively rapid pixel responses across the board. This means that the connectivity layout doesn’t have restrictions, so you get a full range of options with this model. With the AW2521HF, you need to connect the monitor up via DisplayPort and enable ‘FreeSync’ in the ‘Game’ section of the OSD. ‘IPS glow’ also featured, but appropriate room lighting took the edge off this. 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. 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. Things aren’t quite up to the level of the TN reference, but there are no particularly pronounced weaknesses either. Colour gamut 'Test Settings' Colour in games and moviesThe monitor provided a rich and natural appearance to Battlefield V. The monitor provides comprehensive sRGB colour gamut coverage and a bit of extension beyond, but stays well short of extended colour spaces such as DCI-P3. Some models are specifically validated as G-SYNC compatible, which means they have been specifically tested by Nvidia and pass specific quality checks. 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. Note that we have no way to accurately measure input lag with Adaptive-Sync active in a variable refresh rate and frame rate environment. The final point to note is that FreeSync only removes stuttering or juddering related to mismatches between frame rate and refresh rate. Finally, note again that you can go to ‘Game Enhance Mode’ in the ‘Game’ section of the OSD to activate the ‘Frame Rate’ feature. There is a list of GPUs which support the technology here, with the expectation that future AMD GPUs will support the feature too. The ‘Fast’ setting only showed a relatively small amount of this, whilst the ‘Super Fast’ and ‘Extreme’ settings ramped this up. The monitor performed well here, without clear shifts in saturation or colour tone. OSD Setup & Calibration. Some users prefer to leave VSync enabled but use a frame rate limiter set a few frames below the maximum supported (e.g. Plus a bit of overextension, in the green to red region.
