An important concept detailed in the article is perceived blur, which is contributed to by the pixel responses of the monitor and the movement of your eyes as you track motion on the screen. The monitor is set to Standard, but similar observations were made with other presets, including Creator (regardless of configuration), as well as at other refresh rates. We also used the monitor for a week prior to readings being taken with the monitor running through several OLED Pixel Refresh cycles. Viewing angles But for most people the curve should feel a natural addition which is easy to adapt to. Some game engines will also show stuttering (or hitching) for various other reasons which wont be eliminated by the technology. Though plastics were used in favour of metals for the construction of the monitor, it certainly felt solid if rather chunky in its design. Other advantages of the G-SYNC module include the fact there isnt a defined LFC boundary as you get with Adaptive-Sync models (usually 48Hz), with slight momentary stuttering when its crossed. Open up AMD Software and click Settings (cog icon towards top right), then Graphics. Exceptional static contrast and glossy screen surface with strong anti-reflective properties, compelling and highly dynamic HDR experience with good pop and vibrancy But very few do and we still felt the overall saturation levels and general representation of shades were pleasing in terms of vibrancy. The QD-OLED panel performed exceptionally well in terms of colour consistency and viewing angles, which was combined with a generous gamut for vibrant colour output. Below you can see things bumped up slightly, to 144Hz. The SpyderX Elite was used to assess the uniformity of lighter shades, represented by 9 equally spaced white quadrants running from the top left to bottom right of the screen. Performance on the black level test was strong. There were no shifts between saturated red, orange and green across the screen or even with significant head movement. With an LCD, changing brightness alters backlight brightness and this affects all shades in a relatively even fashion. Limited availability, active cooling and fringing will be issues for some users, image retention a potential issue with integrated measures to combat it part of the experience Open up AMD Software and click Settings (cog icon towards top right), then Graphics. Cut scenes and in some cases menus before entering the main game were presented with black borders, but the game itself worked correctly in 21:9. Extra depth to medium shades, but for dark shades tracking is raised and more appropriate than with the 2.2 setting. As such, there is no backlight bleed or associated clouding. With the image appearing as it would on a 27 WQHD (16:9) model. This refers to a relative reduction in high energy blue light due to the large and relatively broad peaks of green and red energy also produced. You have to type every instruction carefully, making sure that it's clear and understood by your readers. VRR (Variable Refresh Rate) technology Our article on the resolution explores this experience for both games and movies in more detail. Note that Cyberpunk 2077 enforced full screen (stretch to fit) GPU scaling, distorting the image as shown when running at a resolution that has a non-native aspect ratio such as 16:9. 2560 x 1440 (WQHD) is displayed perfectly whether the monitor or GPU is handling the scaling. As usual, if youre running the monitor at 3440 x 1440 and viewing lower resolution content (such as a 1920 x 1080 Full HD video) then it is the GPU and software that handles the upscaling. As usual, we tested G-SYNC using various game titles and found the experience very similar an all of them. Even for games where our eyes scanned from centre to edge, we didnt find the curve particularly noticeable as we might with a steeper curve. The images below shows how things appeared with using the Creator preset set to sRGB, with the top image showing the 2.2 and the bottom image the 2.4 gamma setting. The fairly generous Adobe RGB coverage gives decent potential for work within that colour space, though higher coverage would be ideal. The gamma handling was quirky, changing with brightness and never hitting the 2.2 curve at all points regardless of OSD adjustment. Performance on the white saturation was good. Even for games where our eyes scanned from centre to edge, we didnt find the curve particularly noticeable as we might with a steeper curve. They may appear as an interference pattern, mesh or interlaced lines which break up a given shade into a darker and lighter version of what is intended. Creator = DCI-P3 (Gamma 2.6, default) 2.7 6818K Very similar appearance to factory defaults, with gamma set to 2.6 and brightness marginally lower at given setting. All patterns were visible against the white background. Colour gamut 'Test Settings' Like many animated titles, Futurama includes large areas of single shade making it a particularly unforgiving test of colour consistency. As a reminder, the colour gamut of the monitor is shown in the representation below, where the red triangle shows the monitors colour gamut, the blue triangle DCI-P3 and green triangle sRGB. Unlike with the reference screens, there are no visible weaknesses from slower than optimal pixel responses. The following observations were made in a dark room. If you are interested in supporting the channel, here are some Amazon affiliate links to media streaming devices, TVs, and related products that I recommend. This monitor uses QD-OLED technology with self-emissive pixels rather than relying on a backlight. For example, you might be observing a particularly bright glint on a shiny object or small patch of sky, then see those bright elements become less bright and brilliant because youve moved your character and introduced a lot of other bright shades into the scene. HDR (High Dynamic Range) on an ideal monitor involves the simultaneous display of very deep dark shades and brilliantly bright light shades. This reveals provision for 100 x 100mm VESA mounting if you wish to use an alternative stand or mount. Our article on the resolution explores this experience for both games and movies in more detail. In a nutshell, by combining these two technologies, you inherit all the advantages of OLED such as per-pixel illumination and a theoretical infinite contrast ratio while eliminating two of its biggest drawbacks: low peak brightness and burn-in. The HDR10 pipeline uses 10-bits per colour channel, which this monitor also supports. Our observations below with respect to very dark shades mainly relate to how things appear in dimmer lighting conditions. Because of the self-emissive nature of this display, black depth is 0 and contrast ratio essentially infinite as measured with the colorimeter regardless of settings used. Screens based on LG Displays WRGB OLED rely on a white subpixel to deliver strong luminance, diluting saturation in a way that doesnt occur on QD-OLED or LCD technology. Well therefore focus on various Battlefield titles in this section, to keep things simple. The presets with named game genres upset the image in various ways that cant be counteracted in the OSD. Timestamps: Because of the essentially instantaneous pixel responses, there is not even the most minor mask of additional perceived blur for any of this movie content. That means that if the game is running up to 175fps, the monitor will adjust its refresh rate to match. The images below shows how things appeared with using the Creator preset set to sRGB, with the top image showing the 2.2 and the bottom image the 2.4 gamma setting. In brighter conditions you can see some reflections when observing darker shades, particularly reflections of brighter objects. You should then ensure that the first slider is set to Enabled. Cut scenes and in some cases menus before entering the main game were presented with black borders, but the game itself worked correctly in 21:9. Brightness = 75 (according to preferences and lighting) Aw3423DW vs X34 Predator (2015) Capped @100FPS and 100Hz/FPS God of War. With our RTX 3090 this was not commonly observed during gameplay, simply as the frame rate was generally relatively high and fairly stable. For reference, this model provides ~80% Rec. The QD-OLED panel performed exceptionally well in terms of colour consistency and viewing angles, which was combined with a generous gamut for vibrant colour output. These titles offer sufficient flexibility to allow assessment across a very broad range of refresh rates on our RTX 3090. The first image below shows the refresh rates supported for the native 3440 x 1440 (UWQHD) resolution via suitable versions of DP and the second via suitable versions of HDMI. The monitor has a claimed average DeltaE 2000 2 within the sRGB colour space (sRGB gamut selected) and DCI-P3 colour space (DCI-P3 gamut selected). Buy from Amazon But even if youre not interested in or able to get hold of this specific model, it certainly offers a nice glimpse into what can be expected from future models adopting similar technologies in a range of screen sizes and resolutions. The image below gives a rough idea of how things looked here, though note that the grey background appeared more uniform to the eye than it appears in the photo. This didnt generally detract from how enjoyable the screen was to use under HDR and its clear strengths in both colour and contrast. You should then ensure that the Custom Color slider to the right is set to Enabled and Color Temperature Control set to Disabled. Due to the exceptional contrast and black depth they could still be distinguished from the background. As usual, we tested G-SYNC using various game titles and found the experience very similar an all of them. An important concept detailed in the article is perceived blur, which is contributed to by the pixel responses of the monitor and the movement of your eyes as you track motion on the screen. 2020 there. This is a good practical speed to take such photographs at and highlights both elements of perceived blur well. Monitor Settings Gamma (central average) White point (kelvins) Notes Standard (Factory Defaults) 2.3 6778K A highly vibrant look to things with strong saturation. Weve also experienced a reduction in issues such as micro stuttering where a module is used vs. Adaptive-Sync (including G-SYNC Compatible). Selecting Color Space = sRGB does clamp the gamut to sRGB though, as an sRGB emulation setting. Colour consistency is very strong, without the clear shifts observed on VA or TN LCDs. There was certainly plenty of vibrancy as well as exceptional variety here. Note: The test patch used under SDR is a fairly large white box (60mm x 60mm) in the centre of the screen, surrounded by a bit of light grey with black text for the UI elements of the program. As covered in the article, the tool can also provide DCI-P3 and Adobe RGB emulation. This is problem #1. This enhanced precision helps the monitor put its generous gamut to good use and improves the nuanced shade variety for both brighter and darker shades. OnePlus 3. This can include temporary afterimages which are shown on the screen, or in more severe cases it can include permanent damage. When the two are in sync it gets rid of the tearing (VSync off) and stuttering (VSync on) that occurs when the two are desynchronised. There was certainly plenty of vibrancy as well as exceptional variety here. This, coupled with the inclusion of a flipped version of the shade sheet, allows both accuracy and colour consistency to be visually assessed. The vibrant look with strong saturation is one some will really like and find very appealing, but others will prefer the more toned down and as the developers intend look of sRGB emulation, such as setting the Creator preset to Color Space = sRGB. HDR continues to be a pain point for gaming monitors. Darker on dark areas and lighter on light areas produce less noticeable blue tones. Vegetation showcased some very lush-looking shades as well as some highly vivid brighter green shades. The gamma handling was quirky, changing with brightness and never hitting the 2.2 curve at all points regardless of OSD adjustment. An X-Rite i1Display Pro Plus (Calibrite ColorChecker Display Plus) was used to measure the luminance of white using various settings, including those found in the calibration section. There was certainly plenty of vibrancy as well as exceptional variety here. For example, you might be observing a particularly bright glint on a shiny object or small patch of sky, then see those bright elements become less bright and brilliant because youve moved your character and introduced a lot of other bright shades into the scene. The Frame Rate feature found under Game Game Enhance Mode in the OSD will again reflect the frame rate of the content within the VRR window, with Adaptive-Sync active. Performance here is much stronger than on any LCD weve observed. This can be particularly noticeable for static shades of a fixed brightness, such as HUD elements in games. 2020 there. Our unit also showed strong uniformity for brighter, medium and darker shades. 2.2 You will therefore still get some oversaturation within the DCI-P3 colour space. As we explored earlier, gamma changes with brightness on this model and gamma is actually far too low overall using the 2.2 setting at the low brightness levels required for this assessment. The Alienware AW3423DW paints a pretty picture while using HDR, but enabling HDR in Windows hurts color accuracy and coverage. The greyscale gradient appeared smooth without obvious banding or dithering. We explore this in the subsequent section of the review. One game title we tested, The Outer Worlds, didnt support 21:9 at all. Some game titles will activate HDR correctly when the appropriate in-game setting is selected. Responsiveness (VRR). The other titles we tested worked correctly, including; Battlefield 2042 (and other BF titles), Shadow of the Tomb Raider, Call of Duty: Vanguard and Cyberpunk 2077. HDR can be used at the same time as Adaptive-Sync, too. Because theres quite a lot to cover here, well first focus on the subpixel layout. The M27Q shows distinct powdery trailing due to moderate weaknesses in pixel response times at this refresh rate. Including comparisons with a given model where the monitor handles the dithering at some refresh rates and the GPU handles it at others. The article also explores some compatibility concerns. We refer to these as interlace pattern artifacts but some users refer to them as inversion artifacts and others as scan lines. The purple block appeared pinkish purple throughout the screen, free from the shifts youd observe on LCDs (particularly VA and TN models). We recorded 94% Adobe RGB coverage with some extension beyond, particularly towards the red corner of this representation. Note that there is always some disparity between how emissive objects (monitor) and non-emissive objects (printed sheet) appear. The desktop background is shown surrounding that complete with desktop icons to the left and the taskbar at the bottom (example). The UFOs move across the screen from left to right at a frame rate matching the refresh rate of the display. At this point wed usually point out the advantages of the G-SYNC module in terms of supporting variable overdrive, re-tuning the acceleration across the refresh rate range to prevent strong overshoot at lower refresh rates. But here well summarise what they do for you in real world scenarios. The other titles we tested worked correctly, including; Battlefield 2042 (and other BF titles), Shadow of the Tomb Raider, Call of Duty: Vanguard and Cyberpunk 2077. Whilst the Creator mode is greyed out, this will be selected if thats what you were using under SDR before activating HDR. Colour reproduction The screen surface provided a smooth (non-grainy) look to lighter shades and didnt impede them with any additional layering in front. 90% Unlike the screen used in the article, the Dell Alienware includes a curve a moderate curve at 1800R. We did not observe either artifact type on this monitor. OLED technology has been on the horizon for quite some time. This monitor is certified by TV Rheinland with the status of Low Blue Light (Hardware Solution), which makes it suitable for Dells ComfortView Plus designation. A highly vibrant look with strong depth and saturation overall, with a suitably blended appearance to dark detail. Most titles natively support the 3440 x 1440 resolution and 21:9 aspect ratio, whilst a minority may have minor issues such as HUD placement being odd or may not support the resolution at all. Weve also included the refresh rate used in Windows for most of the review, just for reference. Lagom contrast tests At 60Hz, above, the UFO appears soft and unfocused without clear internal detailing. This may be faint and as a result isnt usually distracting like more distinct weaknesses, but its still there and adds a bit of perceived blur. A 0.1ms grey to grey response time is specified and though we often say to pay little attention to such figures, OLED technology is known for very strong pixel responsiveness. This indicates a very low viewing angle dependency to the gamma curve of the monitor, characteristic of OLED. This is a title weve assessed using a broad range of monitors under HDR and we know it has a good HDR implementation. The colour gamut, screen surface and strong contrast (especially when a given shade was surrounded by darker content) aided this. As above with reduced gamma. Whilst this may be too limited for some users, most people tend to settle for a brightness somewhere between 100 cd/m and 200 cd/m which this monitor can provide without issue. It was free from extra yellowing at different points of the screen, again more consistent than your typical LCD. Conclusion Darker elements within scenes such as shadow detailing also benefited from the strong shade depth, with medium shades again having a definite solidity to them. Monitors with particularly strong contrast are prone to flickering for some shades during heavy frame rate fluctuations. You should then ensure that the first slider is set to Enabled. This is exaggerated in images and videos showing the monitor, which makes it look like theres a defined pinching centrally. There was a beautiful and pure look to golds, some really solid and eye-catching red flowers and painted pottery and striking blues as well. The input lag was fairly low and wont be an issue for most people, but not quite as low as we typically see on models with G-SYNC modules. 2.3 They show various titles running the native 3440 x 1440 resolution (21:9) and the same scenes shown with 2560 x 1440 (16:9) to give you an idea of the extra horizontal FOV offered. The images below show the desktop and some multi-tasking on the screen. Bright ambient lighting can be problematic for any LCD weve tested as well, imparting clear glare which floods the image with a hazy look (anti-glare) or causing reflections (glossy) that are usually more distinct than those observed here. If you use the Creator preset mode and select Color Space = DCI-P3, this doesnt clamp the gamut to DCI-P3 and instead uses the native gamut shown above. Colour gamut 'sRGB' There are many ~34 3440 x 1440 Ultrawide models on the market. It can be observed for medium-dark shades which arent particularly near-black as well. The image below shows the letters PCM typed out in size 11 (top) and 72 (bottom) as black text on a white background with ClearType optimisation performed. We felt this added to immersion and in some cases could be considered a competitive advantage. Other advantages of the G-SYNC module include the fact there isnt a defined LFC boundary as you get with Adaptive-Sync models (usually 48Hz), with slight momentary stuttering when its crossed. Also note the white dot on the panel border, which appears tiny and less bright in reality, is a calibration mark used in production of the panel and is often found on LCDs as well. Whilst isolated or relatively small areas of brightness can be given good pop with elevated brightness, where brighter shades dominate the ABL (Automatic Brightness Limiter) comes into play rather aggressively. Note: We found the monitor sometimes reported the HDR setting as HDR 400 True Black even though it was running HDR Peak 1000, as thats what we set it to. This included seamless operation throughout the very generous VRR range. Whilst isolated or relatively small areas of brightness can be given good pop with elevated brightness, where brighter shades dominate the ABL (Automatic Brightness Limiter) comes into play rather aggressively. For reference, this model provides ~80% Rec. The technology worked seamlessly regardless of how low the frame rate (and therefore refresh rate of the display) dipped. Including comparisons with a given model where the monitor handles the dithering at some refresh rates and the GPU handles it at others. A touch of extra richness in places, such as for peach pink (20) and light chocolate brown (24), but a much closer match than using the native gamut. The photos below are again just for illustrative purposes, exaggerate the curve and in no way indicate how the monitor would look in person. For reference, our system sits under the desk and is air-cooled. The UFOs move across the screen from left to right at a frame rate matching the refresh rate of the display. The contrast gradients were displayed well with distinct brightness steps in all cases. The input lag was fairly low and wont be an issue for most people, but not quite as low as we typically see on models with G-SYNC modules. The Fast option enables a technology called Fast Sync, which only applies above the refresh rate and frame rate ceiling (>175Hz / 175fps). With our Radeon RX 580, we were able to activate the technology via DP (first image) but not HDMI (second image). This can include temporary afterimages which are shown on the screen, or in more severe cases it can include permanent damage. You can also observe a dimming of medium or medium-bright shades under these conditions. The screen surface and strong contrast performance also aided the pop on both titles, much as explored in the contrast section earlier. This provides a similarly effective GPU-side gamut clamp to the AMD driver option. You can also observe a dimming of medium or medium-bright shades under these conditions. A more achievable near-term goal is support for at least 90% DCI-P3 (Digital Cinema Initiatives standard colour space) coverage. The contour map below shows these deviations graphically, with darker greys representing lower luminance (greater deviation from brightest point) than lighter greys. The monitor delivered the usual 21:9 experience for movies and games with a decent amount of (horizontally biased) desktop real estate for productivity purposes. The second image shows the monitors colour gamut (red triangle) compared to Adobe RGB (purple triangle). You should then ensure that the first slider is set to Enabled. The image below is a macro photograph taken on Notepad with ClearType disabled. Under moderate natural lighting (not overly bright but not dim either) wed say it was still quite strong though not clearly superior to what a good VA LCD with ~3500:1+ static contrast might offer in terms of depth. Contrast in games and movies Whilst isolated or relatively small areas of brightness can be given good pop with elevated brightness, where brighter shades dominate the ABL (Automatic Brightness Limiter) comes into play rather aggressively. If the character was repositioned so the light streaming in from above dominated, the ABL kicked in and dimmed things quite a bit. During our review period we spent around a month using the monitor pretty solidly, including with a good chunk of time spent on the desktop. Whilst isolated or relatively small areas of brightness can be given good pop with elevated brightness, where brighter shades dominate the ABL (Automatic Brightness Limiter) comes into play rather aggressively. As covered, most games use HOR+ scaling so you gain horizontal FOV (can see more of the game at once) compared to a 16:9 model whilst the vertical FOV remains the same. To ensure the monitor rather than GPU is handling the scaling process, via HDMI where its supported, you need to make sure the GPU driver is set up correctly. With GPU scaling you could avoid this softening if you select No scaling (which uses 1:1 pixel mapping), but the image area is then significantly smaller. Because the developers target wider colour spaces than sRGB, the oversaturation observed under SDR wasnt present. The high frame and high refresh rate combination also decreases perceived blur due to eye movement, much as we demonstrated earlier using Test UFO. And no real undersaturation of note, just a touch for a few shades such as aquamarine (4) which verges slightly too much on aqua and gamboge (23) which verges a bit too much towards a yellower than intended version of the shade.
