This allows both elements of perceived blur to be highlighted, rather than simply capturing pixel responsiveness. A 27" WQHD member of the UltraSharp series with full ergonomic flexibility and slim bezels. This indicates a low viewing angle dependency to the gamma curve of the monitor, as you’d hope for from an IPS-type panel. This was by no means extreme and there was not a smeary or ‘layered’ appearance to the graininess. Chief amongst these is the concept of perceived blur, which is contributed to not only by the monitor’s pixel responsiveness, but also the movement of our eyes as we track motion on the screen. Some dark detail was masked a little too effectively, but nothing extreme – and the ‘Standard’ mode enhances this visibility if preferred. The diagram below compares the monitor in ‘Standard’ mode to the sRGB reference space. When observing light shades such as white you could see that the colour temperature was somewhat warmer in this region. left at automatic) to set the monitor to 74Hz. The monitor certainly didn’t provide the same sort of depth or atmosphere as some models, such as a VA monitor with strong contrast. This second factor (eye movement) is the predominant contributor to perceived blur on modern monitors, although pixel responsiveness also plays an important role. Good subtle distinctions were evident on character skin tones, clothes and vegetation in the environment as well. ComfortView 2.2 5272K This is an effective Low Blue Light (LBL) setting. The red block appeared a fairly rich red throughout. Alternatively, static interlace patterns may be seen with some shades appearing as faint horizontal bands of a slightly lighter and slightly darker version of the intended shade. At 60Hz (above) the UFO appears soft without sharp focus or clearly defined details. But while it has a nice selection of ports, it does lack that one important connector: USB-C. Dell has been slow to reduce this two-and-a-half-year-old monitor’s price as it ages, and the company currently sells it for close to the same price as the Dell P2720DC, a very similar monitor that does include USB-C. We would recommend that you go with that Editors' Choice-winning model. It significantly reduces the strength of the blue channel, although maintains a strong green channel. As usual, if you’re running the monitor at 2560 x 1440 and viewing 1920 x 1080 content (for example a video over the internet or a Blu-ray, using movie software) then it is the GPU and software that handles the upscaling. Dell U2719D is a very good monitor for office use. The display of third-party trademarks and trade names on this site does not necessarily indicate any affiliation or the endorsement of PCMag. And when we tested Adobe RGB coverage in standard mode, the U2719D covered just 73.8 percent of that color space, which is used mostly for print photography. We used a Custom Resolution in Nvidia Control Panel (all timings etc. But only slightly, so quite well-blended in its appearance. Sometimes you could observe a bit of ‘break-up’ trailing for these sorts of transitions, too, when some of the shades contained in the object or background colour appeared to leach out slightly. It indicates a fairly low signal delay which most users shouldn’t find bothersome. This indicates a low viewing angle dependency to the gamma curve of the monitor, as you’d hope for from an IPS-type panel. As we explore later, we didn’t observe any particular issues with this when running the monitor at its standard 60Hz refresh rate. It gave a slight edge overall, particularly during rapid movement. We refer to these as ‘interlace pattern artifacts’ but some users refer to them as ‘inversion artifacts’ and others as ‘scan lines’. Observing a broader spread of transitions, including some at faster speeds (i.e. The ‘Fast’ setting again appears without obvious overshoot. They appeared smoother than on some matte screen surfaces, but had a slight ‘misty’ graininess to them. when gaming) and considering how things ‘feel’ rather than just ‘look’ did reveal some slight differences as we explore shortly. We used a small tool called SMTT 2.0 and a sensitive camera to compare the U2719D’s latency with a screen of known latency. This indicates some weaknesses in pixel responsiveness. Responsiveness. Overall the Dell U2719D is a welcome addition to the UltraSharp series. Fairly low input lag and well-tuned pixel responsiveness, giving a good overall 60Hz performance – plus the ability to apply a mild overclock In addition, a tighter grey-scale tracking on each U2719D helps enable ultra-smooth colour gradation. Viewing angles It gave a slight edge overall, particularly during rapid movement. The contrast performance was much as we expected given the panel type. Video review The bottom line; strong ‘out of the box’ performance, decent responsiveness and excellent colour reproduction within the sRGB colour space. These became noticeable (although still relatively faint) if the monitor was overclocked, however. The darkest two blue blocks appeared slightly more blended than ideal, but were still faintly visible. The Spyder5ELITE was used to assess the uniformity of lighter colours, represented by 9 equally spaced white quadrants running from the top left to bottom right of the screen. The red block appeared a fairly rich red throughout. These settings offer the user an easy way to achieve that. There was again some ‘powdery’ trailing in places and a little ‘break-up’ trailing, but we didn’t find this distracting or particularly noticeable during normal gameplay. The bottom line; strong ‘out of the box’ performance, decent responsiveness and excellent colour reproduction within the sRGB colour space. The image clarity and vibrancy is therefore better preserved. CAUTION: A CAUTION indicates potential damage to hardware or loss of data if instructions are not followed. The UltraSharp fell a little short of its rated 1,000:1 contrast ratio, tallying a 923:1 score. A moderate amount of ‘IPS glow’ ate away at some detail peripherally, particularly towards the bottom corners. There was also a pleasing array of green shades, including some quite lush-looking deep greens and more muted pastel shades that gave vegetation a good natural look. It’s clear from this analysis that ‘Normal’ is the preferred setting to use here. Input lag was also fairly low and, for those who like a bit of an edge in ‘connected feel’ and perceived blur, we were able to overclock the monitor to 74Hz. (All else being equal, the greater the pixel density, the sharper the image should be.). You can see bright and colourful trailing behind the object. We also analysed colour temperature (white point) deviation of the same 9 quadrants. At lowest height the screen clears the desk by ~36mm (1.42 inches) with the top of the screen ~398mm (15.67 inches) above the desk. The screen surface departed from other some other recent 25-27” WQHD UltraSharps as it employs a medium (‘relatively light’) matte anti-glare finish. This model uses a medium (or ‘relatively light’, depending on how you choose to classify it) matte anti-glare screen surface. On some monitors, particularly but not exclusively those with high refresh rates, interlace patterns can be seen during certain transitions. The monitor presented colours in a rich, varied and natural way on, Finally, we assessed colour reproduction on the Blu-ray of. We explore this process shortly. The maximum luminance was recorded at ‘quadrant 8’ below the centre of the screen (158.3 cd/m²). The video below summarises some of the key points raised in this written review and shows the monitor in action. Highlights View more. Refer to this article from AMD for information on the new interface. On Shadow of the Tomb Raider the monitor again provided a pleasing palette of rich colours, with excellent subtle shade variety. When it comes to overclocking, mileage may vary and there are no guarantees. Negatives We also analysed colour temperature (white point) deviation of the same 9 quadrants. The rear of the monitor uses silver matte plastic predominantly with a bit of matte black plastic lower down. The gamma averaged ‘2.2’ across all settings we tested. The purple block appeared a bluish purple throughout, without obvious transitions to a pink hue. Colour gamut This was supported without significant quality degradation or other issues, so we consider this a ‘comfortable’ overclock. The Dell U2719D, of the UltraSharp series, continues the trend of ever-decreasing bezel size and minimalistic overall design. As shown above, the monitor uses the usual RGB (Red, Green and Blue) stripe subpixel layout. On this model she looked much as she should really, perhaps a touch of extra saturation but nothing particularly noteworthy. Preturile, specificatiile si imaginea pentru Dell U2719D sunt furnizate … Not only can you pass a video signal over a compliant USB-C port in DisplayPort over USB Type C's alternative mode, you can charge or power a laptop connected to a monitor’s USB-C port using USB Power Delivery, up to a maximum of 100 watts. Helping keep the correct ‘identity’ of shades regardless of their on-screen position. Further information on supporting our work. This was not particularly eye-catching and these weaknesses are quite typical on 60Hz IPS-type models. For some transitions there was a light ‘powdery’ trailing, whilst for some transitions there was somewhat heavier ‘powdery trailing’. Aside from our ‘Test Settings’, where various adjustments were made, assume anything not mentioned was left at default. Note that the monitor includes an ‘Aspect Ratio’ setting in the ‘Display’ section of the OSD, as shown in the video earlier in the review. Fairly low input lag and well-tuned pixel responsiveness, giving a good overall 60Hz performance – plus the ability to apply a mild overclock At 60Hz (above) the UFO appears soft without sharp focus or clearly defined details. As ‘Factory Defaults’ but a cooler and slightly more vibrant look to the image. He serves on the Board of Directors of the Amateur Astronomers Association of New York and is a regular columnist for the club’s newsletter, Eyepiece. This was supported without significant quality degradation or other issues, so we consider this a ‘comfortable’ overclock. And there are some systems, such as many games consoles, that will only output at a lower maximum resolution such as 1920 x 1080 (Full HD). The screen uses overdrive / response time compensation (RTC) technology to boost pixel transitions across grey to grey changes as with nearly all modern displays. So a reasonable contrast performance, overall. (Dell doesn't make any Adobe RGB coverage claims for this panel.). There are some slight contrast and colour shifts at sharp angles, but these are far more nuanced than you’d observe on VA or TN models. Colour gamut 'Test Settings' Dell’s UltraSharp series are an established favourite for users looking for a good mix of image quality and performance. This is described elsewhere in the review. The video review is designed to complement the written piece and is not nearly as comprehensive. Some minor weaknesses in pixel responsiveness in places, some users would prefer a significantly higher refresh rate Some nit-picks would include that we would’ve preferred to see a lighter and smoother matte screen surface employed, there were some uniformity issues on our sample and a 60Hz refresh rate with mild overclockability is somewhat restrictive for fast-paced gaming. The darkest two blue blocks appeared slightly more blended than ideal, but were still faintly visible. The video below summarises some of the key points raised in this written review and shows the monitor in action. The following observations were made from a normal viewing position, eyes around 70cm from the screen. There was no noticeable dithering and the final (white) block appeared reasonably smooth without obvious graininess from the screen surface. This indicates some weaknesses in pixel responsiveness. As far as 60Hz monitors go the monitor proved quite responsive. Such scenes didn’t have the atmospheric look that models with much strong contrast would provide and again ‘IPS glow’ came into play. Ensure that ‘No Scaling’ is selected and ‘Perform scaling on:’ is set to ‘Display’ as shown in the following image. There is minimal risk involved and in all likelihood the monitor will last for its useful life in much the same way as if it was run at 60Hz. There were no obvious shifts to more saturated red, orange or green and this remained consistent with reasonable head movement. Using the full factory calibration (‘Standard’) mode, however, revealed all blocks with distinct brightness steps. In our experience we consider this sort of increase in refresh rate to be a ‘mild’ overclock that is completely within manufacturer tolerances. Unfortunately, it doesn't look as good in a dark room and has few additional features. Helping keep the correct ‘identity’ of shades regardless of their on-screen position. You may therefore need to run the monitor at a lower resolution, such as Full HD, with the monitor using a scaling (interpolation) process to map the image onto its 2560 x 1440 pixels. The interpolation process of the monitor is therefore quite usable should you need to use the Full HD resolution for anything, including console gaming. There were no obvious shifts to more saturated red, orange or green and this remained consistent with reasonable head movement. And some of the ‘powdery’ trailing became a little more extended. This value is influenced by both the element of input lag you ‘feel’ (signal delay) and the element you ‘see’ (pixel responsiveness). (Read more about how we test monitors.). As usual, if you’re running the monitor at 2560 x 1440 and viewing 1920 x 1080 content (for example a video over the internet or a Blu-ray, using movie software) then it is the GPU and software that handles the upscaling. Performance in the white saturation test was strong overall. It extends a bit beyond sRGB but not to an extreme degree. Even the slower pixel transitions on the monitor were fast enough for an optimal performance here without imparting any notable weaknesses. Users may wish to run through the ClearType wizard and adjust according to preferences, however. The bottom line; strong ‘out of the box’ performance, decent responsiveness and excellent colour reproduction within the sRGB colour space. There was again no obvious overshoot, regardless of the frame rate of the content. High-contrast transitions involving dark and significantly lighter shades would show this, for example. As an Amazon Associate I earn from qualifying purchases made using the below link. You can also adjust the ‘Sharpness’ setting in the OSD if you like a ‘sharper’ look, although we found the neutral setting worked best and higher settings appeared artificially over-sharpened without really improving the image in any way. Indeed this is intentional due to how the gamma curve is tuned, as noted in the calibration section. It significantly reduces the strength of the blue channel, although maintains a strong green channel. There were some traces of extremely static interlacing if you looked closely, but this would be too minor for most users to notice even from close up. The character skin tones showed appropriate saturation, overall, and were consistent regardless of the character’s position on the screen. Good subtle distinctions were evident on character skin tones, clothes and vegetation in the environment as well. Dell U2719D. The contrast remained strong using the ‘ComfortView’ LBL setting (1024:1) and dropped slightly under the better balanced ‘Color Temp. Timestamps: All three rows of the test are analysed (dark, medium and light cyan background), allowing analysis of a range of pixel transitions and helping to highlight the effect of different shades (grey levels) on pixel response speeds. The maximum luminance was recorded at ‘quadrant 8’ below the centre of the screen (158.3 cd/m²). There was again no obvious overshoot, regardless of the frame rate of the content. The monitor also offers two LBL settings; ‘ComfortView’ and ‘Color Temp.’ set to ‘5000K’. There is also a power button, with Dell’s preferred ‘vertical slit’ power indicator. All three rows of the test are analysed (dark, medium and light cyan background), allowing analysis of a range of pixel transitions and helping to highlight the effect of different shades (grey levels) on pixel response speeds. The screen surface gave a light graininess to brighter elements such as candles, lanterns and the daylight sky. Some nit-picks would include that we would’ve preferred to see a lighter and smoother matte screen surface employed, there were some uniformity issues on our sample and a 60Hz refresh rate with mild overclockability is somewhat restrictive for fast-paced gaming. Fairly low input lag and well-tuned pixel responsiveness, giving a good overall 60Hz performance – plus the ability to apply a mild overclock Dell's $499.99 UltraSharp 27 Monitor (U2719D) is a well-rounded 1440p productivity monitor for your top workers, especially ones whose job, at least occasionally, involves exacting color work such as processing photos for the web. There were some good vibrant elements such as rich orange fires and some brightly painted blue and green objects that stood out nicely. Ensure that ‘No Scaling’ is selected and ‘Perform scaling on:’ is set to ‘Display’ as shown in the following image. Buy from Amazon Running the monitor at 1920 x 1080 (Full HD) provided a somewhat softer look to the image when compared to a native 27” Full HD display. But either way there was a distinct lack of a ‘blocky’ or ‘banded’ appearance from inappropriate gamma or other shade reproduction issues. But if you’re happy with the refresh rate, then this is a definite contender. The monitor was tested at 60Hz (directly below) and also overclocked to 74Hz. So a lot of important boxes ticked. The diagram below compares the monitor in ‘Standard’ mode to the sRGB reference space. Or if they just want to concern themselves with adjusting brightness, assuming their factory calibration is as strong as on our unit. Responsiveness in games and movies We refer to these as ‘interlace pattern artifacts’ but some users refer to them as ‘inversion artifacts’ and others as ‘scan lines’. This includes a ‘1:1’ pixel mapping feature that will only use the pixels called for in the source resolution to present an undistorted, unstretched and unsoftened image with black border around. So you’ll need to make sure the GPU driver is correctly configured so that the GPU doesn’t take over the scaling process. This indicates a low viewing angle dependency to the gamma curve of the monitor, as you’d hope for from an IPS-type panel. Lagom contrast tests You may notice that the subpixels are slightly squat with relatively thick black spaces between them vertically. Brighter elements stood out quite nicely against darker surroundings. *Nutze an der Kasse den Gutscheincode "NBB25LCD" und spare 25 Euro mit der Zahlungsart 0%-Finanzierung. This was not extreme and did not compare to the experience of running a much higher refresh rate than 60Hz. Gamma 'Standard' There is not a distinct difference in perceived blur in this test as the UFO itself appears similar to 60Hz. Slight graininess when observing lighter shades due to the use of a medium matte screen surface, a departure from its predecessor(s) Now it is commonplace among premium displays, thanks to it having some special attributes. The contrast performance was much as we expected given the panel type. The exception to this was the introduction of some relatively faint interlace pattern artifacts that some users could find bothersome, as we mentioned earlier. So you’ll need to make sure the GPU driver is correctly configured so that the GPU doesn’t take over the scaling process. Towards the right of the port area there is a Kensington lock slot. As an Amazon Associate I earn from qualifying purchases made using the below link. All patterns were visible against the background, although the final pattern was less distinct than it ideally would be. Further information on supporting our work. Including both components, the bezels are ~7mm (0.28 inches) at the top and sides and ~8mm (0.31 inches) at the bottom. It doesn’t give an obvious ‘smeary’ or layered graininess as some matte screen surface do, thankfully. The following observations were made. This gives the monitor the potential to output all shades within the sRGB colour space, with a bit of extra vibrancy and saturation in places. That’s got nothing to do with the monitor itself – there is a little bit of softening to the image compared to viewing such content on a native Full HD monitor, but it’s not extreme and shouldn’t bother most users. Negatives Individual targets depend on individual uses, tastes and the lighting environment, however. Because blue light is disruptive to sleep hormones, it’s important to cut it out as much as possible in the hours leading up to sleep. This provides strong glare handling characteristics and imparts a light ‘misty’ graininess when observing lighter shades.   The image clarity and vibrancy is therefore better preserved. Dell . There were minor weaknesses in terms of pixel responsiveness in places, giving some ‘powdery trailing’. The blue light reduction is still significant (especially at reduced brightness), massively reduced from factory defaults. This is described elsewhere in the review. It’s important to remember that individual units vary when it comes to uniformity and you can expect further deviation beyond the points measured. This film has plenty of high-contrast scenes, with bright elements such as fires and explosions cast against a much darker background. Eye-catching but not due to strong oversaturation. You may therefore need to run the monitor at a lower resolution, such as Full HD, with the monitor using a scaling (interpolation) process to map the image onto its 2560 x 1440 pixels. To help maximise accuracy, over 30 repeat readings were taken. Brand. Gerätetyp LED-hintergrundbeleuchteter LCD-Monitor – 68.47 cm (27″) An alternative but still very effective LBL setting. Dell rates the U2719D at 350 nits (candelas per meter squared) of luminance, but it fell well short of that: 258 nits, in my testing. The greyscale gradient appeared smooth without obvious dithering or banding. They often catch the eye due to their dynamic nature, on models where they manifest themselves in this way. We refer to these as ‘interlace pattern artifacts’ but some users refer to them as ‘inversion artifacts’ and others as ‘scan lines’. In our experience we consider this sort of increase in refresh rate to be a ‘mild’ overclock that is completely within manufacturer tolerances. The image appears consistently rich and natural, with just a touch of extra vibrancy in places compared to the factory calibration. The greatest deviation from this occurred at ‘quadrant 1’ towards the top left (139.0 cd/m², which is 19% dimmer). U2719D ... Other reviews. Sometimes you could observe a bit of ‘break-up’ trailing for these sorts of transitions, too, when some of the shades contained in the object or background colour appeared to leach out slightly. Dark areas appeared with appropriate visibility for the most part, especially for the central bulk of the screen. The green block appeared a somewhat yellowish green throughout, without a stronger localised green hue in any particular region. The front is black, while the base, stand, and most of the back is silver-gray. Response time: 8 ms (normal) ; 5 ms (Fast) – (gray to gray) Some nit-picks would include that we would’ve preferred to see a lighter and smoother matte screen surface employed, there were some uniformity issues on our sample and a 60Hz refresh rate with mild overclockability is somewhat restrictive for fast-paced gaming. This is not quite as smooth or light and gives a slight ‘misty’ graininess to the image. This fits in with our own preferences better, but users should certainly feel free to use the ‘Standard’ preset instead. The high end again appeared with a slight misty graininess rather than appearing entirely ‘pure’, but there was no ‘smeary’ or heavy graininess to be seen. The diagram below compares the monitor in ‘Standard’ mode to the sRGB reference space. The bottom bezel slopes downwards towards the rear, the total width accounting for that is ~13mm (0.51 inches). We used this ‘5000K’ setting for our own viewing comfort in the evenings, although not for specific testing beyond this particular setting. And there are some systems, such as many games consoles, that will only output at a lower maximum resolution such as 1920 x 1080 (Full HD). Colour reproduction These settings offer the user an easy way to achieve that. Chief amongst these is the concept of perceived blur, which is contributed to not only by the monitor’s pixel responsiveness, but also the movement of our eyes as we track motion on the screen. The monitor provided a decent contrast performance on Battlefield V, overall. Indeed this is intentional due to how the gamma curve is tuned, as noted in the calibration section. Facing downwards beneath this region is a lock feature for the quick-release mechanism. Aside from our ‘Test Settings’, where various adjustments were made, assume anything not mentioned was left at default. Positives Samsung W270HIAP1 PLS (Plane to Line Switching) LCD, 16.7 million (8-bits per subpixel without dithering). © 1996-2021 Ziff Davis, LLC. Running a custom resolution (overclocking) A moderate amount of ‘IPS glow’ ate away at some detail peripherally, particularly towards the bottom corners. Assume any setting not mentioned was left at default, with the exceptions already noted in the table or in the calibration section. Performance in the white saturation test was strong overall. The video below runs through the OSD menu system. The stand is much less of a space hog on the desk than some designs, with a total depth for the monitor and stand of ~179mm (7.05 inches). Overall clarity and vibrancy was maintained well, alongside relatively good glare handling. The highest white luminance recorded on this table was 362cd/m², whilst the lowest white luminance recorded was 40 cd/m². We made similar observations on Shadow of the Tomb Raider. Nvidia users should open Nvidia Control Panel and navigate to ‘Display – Adjust desktop size and position’. But the lighter elements still stood out quite well against their darker surroundings and didn’t have an overly grainy appearance from the screen surface. As an Amazon Associate I earn from qualifying purchases made using the below link. There is just a sliver of under-coverage (99%) and a tiny amount of over-coverage but really things track the sRGB space very closely. Lagom’s tests for viewing angle tests help explore the idea of colour consistency and viewing angle performance. We also observed the monitor on Shadow of the Tomb Raider, which is a good test for contrast due to the large number of scenes involving dimly lit environments. The monitor presented colours in a rich, varied and natural way on Battlefield V. The in-game environments showcased an excellent range of earthy browns, without the excessive red hue that can creep in on models with a more generous colour gamut. Colour temperature uniformity map We used a Custom Resolution in Nvidia Control Panel (all timings etc. There was no noticeable dithering and the final (white) block appeared reasonably smooth without obvious graininess from the screen surface. This introduced some static ‘interlace pattern artifacts’ which some users could find bothersome, although they were reasonably faint and not everyone would find them annoying or necessarily even notice them. If you have your own calibration device and have a colour-managed workflow, the full native gamut (for 100% sRGB coverage) may be preferred although realistically either setting should work well. The image appears consistently rich and natural, with just a touch of extra vibrancy in places compared to the factory calibration. Response Time= Normal The lower frame rate content (~24fps and 30fps) appeared much as it would on even a very fast TN model, with the frame rate itself being the key barrier to fluidity. 7.4 Mixed Usage. The great stand and wide viewing angles are great for office work, and the 1440p, 27" screen is great for gaming or multitasking. To ensure optimal image quality you’ll want to ensure the monitor is handling the scaling process rather than the GPU. We explore this process shortly. The monitor includes various ‘Preset Modes’; ‘Standard’, ‘ComfortView’, ‘Multiscreen Match’, ‘Movie’, ‘Game’, ‘Color Temp.’ and ‘Custom Color’. It is normal for the first few blocks to appear blended on a monitor tracking the ‘2.2’ gamma curve. Note that the monitor includes an ‘Aspect Ratio’ setting in the ‘Display’ section of the OSD, as shown in the video earlier in the review. There were also some nice vibrant-looking elements such as warm glowing fires, bright purple flowers and brightly painted pottery. The greyscale gradient appeared smooth without obvious dithering or banding. But the lighter elements still stood out quite well against their darker surroundings and didn’t have an overly grainy appearance from the screen surface. On this model she looked much as she should really, perhaps a touch of extra saturation but nothing particularly noteworthy. 5000K 2.2 5137K An alternative but still very effective LBL setting. So you’ll need to make sure the GPU driver is correctly configured so that the GPU doesn’t take over the scaling process.
