Not only it features mostly aluminum on its body, but now it is marginally thinner và fairly lighter – 15.9mm & 1.63 kg. This makes it easier to lớn handle around – however, it is still significantly heavier than the 1.12 kg of the ASUS ZenBook 14 UX433.Sadly, its lid cannot be opened with a single h&. Additionally, the kiến thiết features sllặng bezels and Lenovo has managed khổng lồ put the camera on the orthodox position above the screen.Then we have the base of the device. It is home to lớn a MacBook style speakers, that are firing towards the user. This is a feature we would like to lớn see on more devices since it is more convenient if you place it on the pillow or blankets. Between the pair of speakers, you can see the keyboard. It is a little of a setbaông xã because the key travel is incredibly short. On the bright side, it has clicky feedbachồng and a backlight, however, we think it would have been very easy for Lenovo lớn put a better keyboard with a longer key travel since they have sầu already done it on a significantly thinner device – the Ideapad 730S.Further below there is the touchpad which has a glass cover on top of it and is fast and accurate. Moreover, on its right, you can see the fingerprint reader which is pretty snappy.With the speakers moved lớn the surface, there are only the ventilation grills on the bottom plate. Heat, as expected, is exhausted from in between the base and the display of the máy tính xách tay.PortsThe Ideapad S540’s I/O has some essentials, but it lacks others (no RJ-45 connector). On the left side is located the barrel-style charging plug (we would have loved khổng lồ see a Type-C charging), an HDXiaoMi MI connector, USB Type-C 3.1 (Gen. 2) port, and an Audio Jaông xã. Looking on the right, there are two USB 3.0 ports (one of which has an Always-On functionality), an SD card reader and the reset switch.Display qualityLenovo Ideapad S540 (14″)’s display has a Full HD IPS panel, Mã Sản Phẩm number LG LP140WFA-SPD1 (LGD05EC). Its diagonal is 14″ (35.56 cm), and the resolution – 19đôi mươi х 1080. Additionally, the screen ratio is 16:9, the pixel mật độ trùng lặp từ khóa – 157 ppi, their pitch – 0.161 x 0.161 mm. The screen can be considered Retimãng cầu when viewed from at least 56 centimet (from this distance, the average human eye can’t see the individual pixels).It has comfortable viewing angles. We have sầu provided images at 45 degrees khổng lồ evaluate chất lượng.The maximum measured brightness is 250 nits (cd/m2) in the middle of the screen và 249 nits (cd/m2) average across the surface with a maximum deviation of 11%. The Correlated Color Temperature on a Trắng screen và at maximum brightness is 7825K (average) – colder than the 6500K optimum for sRGB. The average color temperature through the grey scale before profiling is 7700K.In the illustration below you can see how the display performs from uniformity perspective. The illustration below shows how matters are for operational brightness levels (approximately 140 nits) – in this particular case at 66% Brightness (White màn chơi = 140 cd/m2, Blaông xã màn chơi = 0.14 cd/m2).Values of dE2000 over 4.0 should not occur, & this parameter is one of the first you should kiểm tra if you intend khổng lồ use the máy vi tính for color-sensitive work (a maximum tolerance of 2.0 ). The contrast ratio is acceptable – 980:1.To make sure we are on the same page, we would lượt thích to lớn give sầu you a little introduction lớn the sRGB color gamut and the Adobe RGB. To start, there’s the CIE 1976 Unisize Chromatiđô thị Diagram that represents the visible specter of colors by the human eye, giving you a better perception of the color gamut coverage and the color accuracy.Xem thêm: Chuyển File Dwg Sang Jpg, Png Nhanh Và Chính Xác Nhất, Chuyển Đổi Dwg Sang Jpg Trực Tuyến Miễn PhíInside the blaông chồng triangle, you will see the standard color gamut (sRGB) that is being used by millions of people in HDTV và on the web. As for the Adobe RGB, this is used in professional cameras, monitors, etc for printing. Basically, colors inside the black triangle are used by everyone và this is the essential part of the color chất lượng và color accuracy of a mainstream notebook.Still, we’ve included other color spaces like the famous DCI-P3 standard used by movie studtiện ích ios, as well as the digital UHD Rec.20trăng tròn standard. Rec.20đôi mươi, however, is still a thing of the future & it’s difficult for today’s displays khổng lồ cover that well. We’ve also included the so-called Michael Pointer gamut, or Pointer’s gamut, which represents the colors that naturally occur around us every day.The yellow dotted line shows Lenovo Ideapad S540 (14″)’s color gamut coverage.Its display covers a narrow 52% of the sRGB/ITU-R BT.709 (web/HDTV standard) in CIE1976.Response time (Gaming capabilities)We test the reaction time of the pixels with the usual “black-to-white” & “white-to-black” method from 10% lớn 90% and vice versa.We recorded Fall Time + Rise Time = 23 ms.Health impact – PWM / Blue LightPWM (Screen flickering)Pulse-width modulation (PWM) is an easy way to lớn control monitor brightness. When you lower the brightness, the light intensity of the backlight is not lowered, but instead turned off & on by the electronics with a frequency indistinguishable to lớn the human eye. In these light impulses, the light/no-light time ratio varies, while brightness remains unchanged, which is harmful to your eyes. You can read more about that in our dedicated article on PWM.Our instruments didn’t detect any usage of PWM across all brightness levels of the display. This means it is comfortable for long periods of usage, without being harmful to your eyes in this aspect.Blue light emissionsInstalling our Health-Guard protệp tin not only eliminates PWM but also reduces the harmful Blue Light emissions while keeping the colors of the screen perceptually accurate. If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin and your whole body toàn thân. You can find more information about that in our dedicated article on Blue Light.ConclusionsLenovo Ideapad S540 (14″)’s IPS panel has a Full HD resolution, comfortable viewing angles, decent contrast ratio và non-flickering backlight. Its main disadvantage is the poor color coverage (only 52% of sRGB).Buy our profilesSince our profiles are tailored for each individual display Mã Sản Phẩm, this article và its respective protệp tin package are meant for Lenovo Ideapad 540s (14″) configurations with 14.0″ LG LP140WFA-SPD1 (LGD05EC) (FHD, 19trăng tròn × 1080) IPS.*Should you have problems with downloading the purchased tệp tin, try using a different browser lớn open the links you’ll receive sầu via e-mail.
