Outcomes right here have been respectable general. Vital deviation was recorded in the direction of the highest left (DeltaE three.9), with out vital deviation recorded elsewhere. It’s value noting again that individual models differ on the subject of uniformity and the deviation beyond measured points could be anticipated.

Contrast in games and films
On Battlefield V the monitor offered an honest expertise when it comes to distinction. The level of detail in dark areas was much appropriately for the central mass of the display, aided by applicable gamma dealing with. There was some loss of element peripherally because of ‘IPS glow’, although, which offered a bloom that lightened darkish shades. This was most noticeable in the direction of the bottom corners of the display, from a traditional viewing position. The ‘IPS glow’ was at a average degree, quite typical for the panel sort. Brighter shades stood out quite properly towards darker surroundings, whilst the sunshine matte display floor stored them free from apparent ‘smeary’ graininess. Only a mild ‘misty’ graininess in locations, considerably much less obtrusive than most 27” models of this resolution show in reality.
We made comparable observations on Shadow of the Tomb Raider. This title has loads of dark caves and interiors, greatest seen on a monitor with robust distinction efficiency. That’s not one thing that IPS models like this provide, nevertheless. The environment to these dark scenes was missing and positively not helped by ‘IPS glow’ (or the one affordable general static contrast). However it was nice to have a great central degree of element for these dark scenes, whilst the robust gamma consistency prevented the difficulty you’d get on TN models of this measurement. And that’s darkish shades mixing together extremely readily in the direction of the highest of the display an extreme ranges of detail being obvious lower down the display. The light matte display surface stored brighter parts such as the daylight sky and flames in darkish passageways appearing fairly clean, without an apparent layered and grainy appearance. Lastly, we made some observations on the film Star Wars: The Last Jedi. The contrast definitely wasn’t enough to provide this an excessively deep and cinematic look, particularly when viewing in dimmer lighting surroundings. But in additional smart lighting and contemplating the panel sort used, things have been definitely respectable sufficient. Vibrant parts reminiscent of mild sabers and power pulses lighting up deep darkish area stood out fairly properly, whilst once more the display surface prevented giving them an excessively grainy look.
Lagom distinction exams
The Lagom exams for distinction permit specific weaknesses in contrast performance to be identified. The next observations have been made.
- The contrast gradients have been displayed nicely with distinct brightness steps in every case.
- Efficiency on the black degree check was wonderful. The primary few blocks blended into the background readily, which is predicted for a monitor monitoring the ‘2.2’ gamma curve. The remaining blocks showed applicable visibility ranges and steps up in brightness. There was no apparent dithering.
- Efficiency on the white saturation check was excellent. All checkerboard patterns have been seen towards the background, although the final sample was considerably fainter than it might be. It was masked a bit by a light-weight graininess from the display surface.
- The greyscale gradient appeared clean without robust banding or apparent dithering. Some faint banding was evident upon shut inspection, but the general look was blended.
The Philips 276E8VJSB’s colour gamut (pink triangle) was in contrast with the sRGB (green triangle) reference area utilizing our ‘Test Settings’, as shown under. The gamut absolutely covers the sRGB colour area (100%) with some extension beyond this, notably within the green area of this illustration. That provides the monitor the potential to output all shades inside the sRGB colour area, with an additional bit of saturation. This provides a bit more of a vivid look general, but the extension beyond sRGB is way from excessive – so you don’t get extra noticeable oversaturation and issues appear fairly natural and trustworthy to the original sRGB supply general.
The monitor also supplies an sRGB emulation setting (setting ‘Color’ to ‘sRGB’ within the OSD). This cuts down the colour gamut so that it tracks sRGB more intently, shown under with the same triangle colors used as before. There is a little under-extension under sRGB, however nothing severe (98%). The complete native gamut of the monitor does not supply extreme extension and it’s typically desirable to stability issues as greatest you’ll be able to on the monitor aspect relatively than simply going all-out on the software program aspect (i.e. with an ICC profile). Given this, the complete sRGB coverage with the native gamut and that the ‘sRGB’ setting locks off colour channels within the OSD it might make sense to simply use the complete native gamut as a base of calibration. Should you’re absolutely strict about making certain no over-extension beyond sRGB, though, the emulation setting offered here is definitely efficient.
Colour in games and films
The monitor offered a rich, various and pure palette of colors on Battlefield V. The environments appeared a lot as they need to, with some good wealthy greens and nice autumnal brown and pink shades. The slight extension past sRGB within the gamut offered a bit of additional vividness, however nothing extreme – saturation ranges have been solely a bit larger than meant general. Fires had a nice vibrant look to them with out yellows verging on orange or oranges verging on pink. And reddish brown earth appeared quite applicable, relatively than appearing with an excessively robust pink hue. We made comparable observations on Shadow of the Tomb Raider. The sport appeared vivid but pure, with a superb variety of shades. Delicate variations of stated shades (comparable to quite a lot of muted greens and browns) was displayed properly because of the consistency of the IPS-type panel. Saturation was well-maintained all through the display, with solely a little bit of a lift from the color gamut quite than something excessive. Sufficient to keep things wanting quite vivid, however not enough to offer Lara too much of a suntan (or worse, sunburn!)
Shadow of the Tomb Raider highlighted comparable color performance traits. Things appeared vibrant general, with robust but not extreme or garish saturation. This gave the environments a rich look, with numerous deep and luscious greens as well as some extra muted shades. Earthy browns also seemed wealthy, if at occasions too purple as noticed on BF1. Lara’s pores and skin appeared a bit more tanned than meant, however the monitor prevented giving her a sunburnt or lobster-like look (some traditional broad gamut displays may do this). There have been some good vibrant blues, reds and purples displayed for parts resembling fruit and flowers as properly. There was average loss of saturation in the direction of the edge of the display and a few of these shades turn into noticeable more muted at the excessive aspect edges particularly. This was relative to their saturated central look, they didn’t look ‘washed out’ in our view.
We additionally made some observations on the movie Futurama: Into the Wild Inexperienced Yonder. This can be a notably unforgiving check for colour consistency as there are giant areas of individual shade. Any shifts in saturation or tone listed here are usually straightforward to spot. The monitor performed properly here, allowing a superb variety of subtly totally different shades to be displayed. Pastel shades appeared appropriately muted, with a nice number of orange and pink hues which may typically be lost. There have been some respectable deep shades similar to purples and some nice neon inexperienced and pink shades. The vibrancy of these shades wasn’t as head-turning as on some fashions, with extra generous color gamuts. However it was undoubtedly still there to an honest diploma, giving this title the kind of look it craved general.
Lagom’s exams for viewing angle checks help explore the thought of colour consistency and viewing angle performance. The following observations have been constructed from a traditional viewing position, eyes 70 – 80cm from the display. Notice that the shifts explored are extra pronounced the closer to the display you’re sitting.
- The purple block appeared a bluish purple all through. There was a slightly stronger pink hue in the direction of the far left, however no excessive shifts. There weren’t the type of flashes of pink you’d get alongside head motion on VA or TN panels.
- The purple block appeared a strong and fairly wealthy purple throughout.
- The green block appeared a moderately saturated green chartreuse. There was no specific space with robust additional yellowing as you’d sometimes see on models with weaker viewing angle performance.
- The blue block appeared deep blue all through.
- The Lagom text appeared a blended gray all through with a slight cool-green tint to the striping. There were no flashes of saturated green, purple or orange and prepared shifts between these alongside head motion. This indicates a low viewing angle dependency to the gamma curve of the monitor, as typical for an IPS-type panel. The photograph under provides a rough concept of how the Lagom text check appeared.
The following video exhibits the Lagom text check, a combined desktop background and darkish desktop background from numerous viewing angles. For the combined picture you’ll be able to see some shifts in colour and contrast, more pronounced at steeper angles. There isn’t a ‘colour inversion’ as you’d observe on a TN mannequin vertically and the shifts will not be as extreme. The final third of the video exhibits a dark desktop background and highlights ‘VA glow’ which blooms out from more excessive angles. This is quite constrained general and is just actually noticeable on the video where the viewing angles are fairly steep. This reflects our earlier observations from a traditional viewing place, where ‘VA glow’ wasn’t a problem value worrying about on this mannequin.
Interlace sample artifacts
On some screens, notably however not solely these with excessive refresh charges, interlace patterns could be seen during sure transitions. We refer to those as ‘interlace pattern artifacts’ however some customers confer with them as ‘inversion artifacts’ and others as ‘scan lines’. They could seem as an interference sample or mesh or interlaced strains which break up a given shade into a darker and lighter model of what is meant. They typically catch the eye resulting from their dynamic nature, on models where they manifest themselves on this approach. Alternatively, static interlace patterns may be seen with some shades showing as faint horizontal bands of a barely lighter and barely darker version of the meant shade. We did not observe either artifact sort on this monitor.
A small utility referred to as SMTT 2.zero was used alongside a sensitive digital camera to analyse the latency of the 276E8VJSB, with over 30 repeat readings taken to assist maximise accuracy. Utilizing this technique, we calculated 2.79ms (~1/6th of a frame at 60Hz) of input lag. Word that the enter lag measured right here is influenced by both the aspect you ‘see’ (pixel responsiveness) and the aspect you ‘feel’ (signal delay). It indicates a very low signal delay which shouldn’t hassle even sensitive users.
Perceived blur (pursuit images)
Our article on responsiveness explores the important thing elements affecting monitor responsiveness. Chief amongst these is ‘perceived blur’, contributed to by both the pixel responsiveness of the monitor and eye motion as you monitor movement on the display. This second issue is often dominant on trendy screens, although both elements are necessary. We also introduce a images technique referred to as ‘pursuit photography’, which makes use of a shifting slightly than static digital camera to capture snapshots of movement on a monitor in a means that reflects each these key parts of perceived blur fairly than only reflecting pixel responses.
The pictures under are pursuit pictures taken utilizing the UFO Movement Check for ghosting, with the check operating at 960 pixels per second. This can be a good sensible velocity for capturing such pictures and highlights both parts of perceived blur nicely. The UFOs transfer across the display from left to proper at a frame price matching the refresh fee of the show. All background shade ranges (darkish, medium and lightweight) have been used with the monitor set to all its ‘SmartResponse’ pixel overdrive settings; ‘Off’, ‘Fast’, ‘Faster’ and ‘Fastest’. The ultimate column exhibits a reference, a quick TN model (ViewSonic XG240R) displaying what issues appear to be the place pixel responsiveness isn’t usually a limiting issue.
The UFO seems delicate and unfocussed with out sharp particulars, reflecting a average quantity of perceived blur as a consequence of eye (digital camera) motion. This facet can also be reflected within the reference photographs. There are also numerous levels of trailing behind the thing, reflecting weaknesses resulting from suboptimal pixel responsiveness. With ‘SmartResponse = Off’ there’s vital trailing behind the item for the dark (prime row) and medium (center row) backgrounds and just a bit for the light background (bottom row). The ‘Fast’ setting cuts down on this, so a bit bit stays but significantly much less. The sunshine background exhibits a small amount of overshoot (inverse ghosting) as a barely shiny (‘halo’) path behind the UFO. The ‘Faster’ setting additional cuts down on the trailing. There’s now only a whiff of light ‘powdery’ trailing for the dark background. The medium and lightweight backgrounds each present some overshoot (slightly shiny trailing) however nothing excessive. The ‘Fastest’ setting introduces a small amount of overshoot for the dark background and significantly increases overshoot for the medium and lightweight backgrounds. It’s very vibrant and apparent. In response to this analysis and certainly broader evaluation in-game, we think about ‘Faster’ to be optimum. Customers preferring slightly decrease overshoot at the expense of a bit extra typical trailing might need to attempt the ‘Fast’ setting as an alternative.
Word that we’ll not be together with a piece on overclocking, as the monitor skipped frames when set a lot above 60Hz at its native decision or indeed decrease resolutions corresponding to Full HD.
Responsiveness in games and films
On Battlefield V there was a average degree of perceived blur, primarily brought on by eye movement and linked to the 60Hz refresh fee. There have been some slight weaknesses beyond that, though nothing that basically stood out in a distracting approach. A number of the pixel transitions involving brighter shades towards a much darker background (and typically darkish shades towards a much brighter background) produced a ‘powdery’ trailing just like that proven in the prime row of the UFO Motion Check for ghosting earlier. This was most noticeable when you moved past white text prompts or interplay notifications towards darkish backgrounds. However even that was less noticeable than the kind of weaknesses (‘smeary’ trailing) you sometimes observe for comparable transitions on VA models. There was additionally some overshoot in locations. A darkish tree trunk towards a dusky sky, for example, produced a semi-transparent (‘snail slime’) trail behind the tree that was slightly brighter than the background. And observing very vibrant shades resembling lamps towards medium backgrounds typically revealed trailing that was barely darker than the background (‘dirty trailing’). We didn’t find either sort of overshoot notably robust or obnoxious and so far as overshoot goes these examples have been far less obtrusive or noticeable as they might be.
We made comparable observations on Shadow of the Tomb Raider. It was really the perceived blur as a consequence of eye movement that dominated, with secondary weaknesses resembling a little bit of ‘powdery’ trailing and a few overshoot very a lot secondary. And never adequate to actually detract from the gameplay. We also made observations using film content material at a variety of body rates, together with 24fps – 30fps and 60fps content. There were no vital weaknesses noticed resulting from pixel response behaviour here. For the higher frame price content exactly the same slight weaknesses have been exposed as when gaming at 60fps. For the decrease body fee content material these weaknesses have been not likely evident, except for a small amount of overshoot (vibrant trailing) in locations. This was delicate and could possibly be eliminated by decreasing the ‘SmartResponse’ setting if desired. The fluidity of motion and pixel response necessities have been considerably limited by the body price itself. The monitor subsequently offered a superb response efficiency for movie viewing without any stand-out weaknesses.
The ‘4K’ UHD expertise
Our article on the ‘4K’ UHD experience explores the pros and cons of the decision on quite a lot of tasks. The article is focussed on a 28” display – the 27” display of the 276E8VJSB presents a really comparable experience. With a pixel density of 163.18 PPI (Pixels Per Inch), many customers will need to use a degree of scaling. We have been in a position to use the monitor without any scaling from our normal viewing distance (~70cm), but textual content and numerous other parts on the display appeared very small certainly and we found this quite strange. We most popular using a reasonably low degree of scaling (‘125%’) labored properly, making things a bit bigger and subsequently less weird-looking while maintaining a superb degree of ‘desktop real estate’. Properly scaled parts (including text on most purposes we used) appeared pretty and crisp as properly, benefiting enormously from the high pixel density. The pictures under are there to offer a tough concept of how issues seem using our most popular ‘125%’ scaling setting on the desktop. The expertise article linked to firstly of this paragraph draws additional comparisons, with numerous totally different scaling levels applied.
The robust 163.18 PPI pixel density additionally brings wonderful detail and clarity to suitably high resolution picture content. Including high-resolution pictures, films and games. Even in case you set the game to pretty low detail ranges, otherwise you’re operating an older title which is way from graphically complicated, there’s nice benefit to be had from the pixel density. Numerous parts merely appear sharper and higher outlined – objects or individuals stand out better from each other and their setting, even quite far into the space. Add in some fancy particle results and excessive resolution textures and the advantages of this pixel density have been very clear to us. The pictures under present numerous recreation titles in action on the monitor. They by no means mirror what the monitor appear to be in individual, they’re merely there for a bit of visual stimulation.
Interpolation and upscaling
The 3840 x 2160 (‘4K’ UHD) decision is relatively demanding, requiring a great amount of GPU power to run easily. Due to this, it might be fascinating to make use of a decrease resolution. And on some methods (some games consoles and so forth.) it might be essential as they don’t help ‘4K’ output. The monitor is ready to use an interpolation (scaling) course of to map lower resolutions reminiscent of 1920 x 1080 (‘1080p’ or Full HD) onto all of its 3840 x 2160 pixels. That you must ensure, as a PC consumer, that the GPU isn’t making an attempt to take over scaling duties. For AMD GPU customers the monitor will deal with the scaling by default, when gaming at non-native resolutions. Nvidia customers should open the Nvidia Management Panel and navigate to ‘Display – Adjust desktop size and position’. They need to make sure that ‘No Scaling’ is selected and ‘Perform scaling on:’ is about to ‘Display’ as shown under.
The ‘SmartSize’ section of the OSD has numerous settings that control the monitor’s scaling behaviour. There’s ‘Panel Size – 27”W (16:9)’ which can ensure all pixels of the monitor are illuminated and the complete display area is used. There’s ‘1:1’, a pixel mapping function that may display the supply decision with none distortion or ‘stretching’ and refill the remaining pixels as a black border. And there’s ‘Aspect’, which can use interpolation vertically however not horizontally. It is meant to take care of the facet ratio of the supply decision but refill as a lot of the display as attainable with that in mind, although it appeared to horizontally compress resolutions with a 16:9 facet ratio so that they appeared stretched and distorted. Contemplating the Full HD resolution, the monitor offered some softening to the image when utilizing interpolation. It definitely didn’t have the same readability and edge definition as a display of this measurement operating Full HD natively. But the softening was not extreme and was truly fairly troublesome to note in the event you sit a bit additional back from the monitor. This was additionally true for the 2560 x 1440 (WQHD) resolution, which truly appeared about nearly as good as we’ve seen it displayed on a 3840 x 2160 model. The softening that was noticed was not improved by growing ‘Sharpness’ within the OSD, that just gave an artificially over-sharpened and admittedly ugly appearance to the image.
As ordinary, for those who’re operating the monitor at 3840 x 2160 and viewing 1920 x 1080 content (for example a video over the web or a Blu-ray, utilizing movie software) then it’s the GPU and software that handles the upscaling. That’s obtained nothing to do with the monitor itself – there’s a little bit of softening to the image in comparison with viewing such content on a native Full HD monitor, however it’s not extreme and shouldn’t hassle most customers.
The video under summarises a number of the key factors raised on this written assessment and exhibits the monitor in action. The video assessment is designed to enrich the written piece and is not almost as comprehensive.
Options & Aesthetics
With its 27” ‘4K’ UHD display, the Philips 276E8VJSB supplies a superb pixel density and a very good amount of desktop real-estate. Even when you end up utilizing a bit of scaling or application-specific zoom, which most mere mortals can be doing. The monitor had a homely look with a nice strong looking and feeling powder-coated metallic crescent-shaped stand. This afforded tilt as the one ergonomic freedom, although, and there was no provision for VESA mounting. The fairly brilliant white pinprick-style energy LED might hassle some users as nicely – it may well’t be disabled within the OSD, so a much less elegant answer comparable to a small little bit of tape can be required. The OSD controls, though intuitive, have been quite choosy about how firmly and in what path you pressed them. Not a serious drawback, in fact, but probably barely annoying to some users.
The monitor offered wonderful gamma handling out of the box and provided provision to easily right white level. Which wasn’t wildly off on our unit out of the box, but was definitely not fairly the place we needed it. There have been numerous gamma settings within the OSD, alongside an array of other settings including numerous Low Blue Mild (LBL) modes. These worked effectively and have been straightforward to activate or deactivate – together with by assigning them to a custom preset. The gamma consistency throughout the display was robust, as hoped for given the panel sort. Static contrast was additionally in-line with our expectations for an IPS-type panel, with a average (but largely common) degree of ‘IPS glow’ eating away at some detail and environment for peripheral sections of the display. We have been fairly pleased with the selection of display surface, which was mild matte anti-glare with a reasonably clean finish. There was only a light-weight graininess when observing lighter shades, straightforward to disregard for probably the most half and quite a bit much less obtrusive than on many competing models.
The palette of colors offered by the display was wealthy and different. There was some extension past the sRGB gamut which lifted up the vibrancy of many shades without robust oversaturation. This allowed the monitor to output shades in a means that was fairly trustworthy to the original supply materials whilst injecting slightly additional vividness. The IPS-type panel’s gamma and shade consistency helped keep this wealthy look all through the display. Far from being some kind of low cost imitation of IPS know-how, we found this Panda Electronics IPS-type panel to carry out each bit as properly if not better in some areas compared to its LG IPS counterparts. An effective sRGB emulation mode was additionally included, effectively chopping again on the colour gamut with out compromising on contrast. The color channels have been locked when using this setting and should you want to make modifications of that nature you’d need to use a colorimeter or make modifications at the software degree by different means, such because the graphics driver.
The monitor offered respectable 60Hz responsiveness, too. Enter lag was nice and low and there were no major issues with pixel responsiveness. A bit of ‘powdery’ trailing in locations and a bit of overshoot, nevertheless it was largely the 60Hz refresh fee that dictated the expertise. Given the worth of the monitor and its clearly superior color efficiency (and actually responsiveness) in comparison with the extra widespread 28” TN options in the worth range, that is value careful consideration. Paying a better worth might grant options like FreeSync help, very rudimentary HDR help and larger ergonomic flexibility or mounting options. Considering, for example, the LG 27UK650, 27UL650 and related models. But if such additions don’t curiosity you then there are far worse methods to spend your cash than on the Philips 276E8VJSB.
The bottom line; robust all-round efficiency at a gorgeous worth, with vivid and various color output and good 60Hz responsiveness.
