A 27-inch diagonal QHD monitor and high color fidelity: are the characteristics of the Lenovo ThinkVision P27h-20, designed for personal and professional productivity, with valuable tricks to better organize the workspace. Lenovo ThinkVision P27h-20 is a 27-inch monitor with a QHD resolution of 2560×1440 pixels intended for productivity uses in the office or at home and boasts high-level color fidelity, thus also addressing graphics professionals. In particular, it is a monitor which, thanks to some expedients we will see in the analysis, proves to be a very interesting workmate to be combined with a portable PC.
The 27-inch diagonal decrees a non-negligible screen size by the tilt mechanism that puts sturdiness and ergonomics first instead of giving in to excessively minimalist designs. The panel is placed on a support that allows height adjustment, with a range of just over 13 centimeters, and rotation on the vertical and horizontal planes to enable the user to set up the panel appropriately. Own workstation. Not only that: the monitor also offers the possibility of being oriented in “pivot” mode, thus proving to be of particular interest to all those who prefer a vertical development monitor.
The small frame and base also allow you to organize multi-monitor configurations effectively. Overall, Lenovo ThinkVision P27h-20 develops a footprint of 208 x 441 x 613 mm, including floor and pedestal, and a weight of 7.35 kilograms. In the base, which extends more forward than back, a groove about 16 centimeters wide has been designed to support smartphones and small tablets. The ground’s surface is large enough to place a compact desktop system, such as an Intel NUC, to the full advantage of reducing the overall dimensions of the work system, as the consequence of maintaining a more orderly and functional space for productivity more easily.
And again, to facilitate the setting up of a tidy workstation, a small rubber strap has been provided at the base of the support, allowing the connection cables to be better accommodated along the pedestal. The mention of connection cables offers us the assistance to talk about the connection ports of this monitor, which are particularly large. The rear panel houses an HDMI 1.4 port, a DisplayPort 1.2 port, four USB 3.1 ports (two on the side), a USB-C port, and an RJ45 Ethernet connector. The upstream USB-C port, therefore, allows you to use this monitor as a hub/port replicator with a single cable capable of supplying power.
This is why we previously defined Lenovo ThinkVision P27h-20 as an interesting workmate for a portable system, provided that it is equipped with a USB-C port. The buttons for adjustment and access to the OSD have been placed in the back, accessible on the right edge. Even the icons identifying the commands are placed laterally, and the buttons do not have a positional correspondence for the items on the On Screen Display. This steepens the learning curve, and there are often unwanted actions when working within the OSD to make image adjustments.
The On Screen Display is essential and allows you to adjust all the fundamental parameters of the image, choose the presets and activate the power delivery function of the USB-C port. The monitor also integrates a pair of stereo speakers. We have now come to the technical characteristics of the Lenovo ThinkVision P27h-20. As we said, it is a monitor built around a 27-inch planar panel with a native resolution of 2560×1440 pixels which defines 108 pixels per inch. This monitor’s “identity card” indicates a maximum luminance of 350 candelas per square meter and a coverage of 99% of the sRGB color space.
The panel has a refresh rate of 60Hz. By its intended use purely based on personal productivity, there are no adaptive refresh rate technologies or particular devices aimed at improving the input lag, as these are technical characteristics that only affect competitive gamers. We subjected the Lenovo ThinkVision P27h-20 to the usual series of measures to verify the panel’s behavior. After the first preliminary analyses, the “Custom” profile without any customization shows the most balanced behavior, as the test results show below.
The results are generally very positive for all the parameters analyzed: the neutrality of the gray scale is quite valid (only in the low lights, where, however, the sensitivity of the human eye is lower than the contained deviations, there is some deviation from the balance) and the gamma curve describes a correct tonal progression, with the average tones just attenuated but without this compromising the reproduction of the images. The maximum recorded luminance is 344 candelas per square meter, with a contrast ratio of 375:1 . As regards the chromatic domain, the gamut triangle detected almost entirely covers the sRGB / REC BT.709 color space. Still, its overall extension is about 10% higher than the reference.
The chromatic fidelity is excellent, with an average DeltaE of the samples of the Gretagmacbeth card of 1.4 with, in general, all the pieces, except two, which remain below DeltaE 2. In summary, we are dealing with a monitor that lends itself well to all office uses and for web graphic production activities that need a color space no more significant than sRGB and where color accuracy is a priority parameter. Within the OSD, it is possible to select other profiles such as Neutral, Reddish, Bluish, and Low Blue Light, in addition to the Custom profile that we have already analyzed and which is also the one that allows the user to make the most significant number of adjustments.
As always, it is worth underlining that if the monitor is to be used in an area where color fidelity is a fundamental element, there is no reason to choose a different profile from the one we measured, given that the others are mainly to introduce color casts (unbalancing the neutrality of the grays) or variations in the tonal progression. The Lenovo ThinkVision P27h-20 monitor is an ideal workmate for those who need high image quality and, simultaneously, need to reduce the overall dimensions of their workstation, rationalizing the spaces and tools at their disposal.
The ability to use the monitor as a port replicator for a portable system, as well as a power source for it, helps keep your desk tidy by eliminating unnecessary cables. Lenovo offers ThinkVision P27h-20 at a list price of 439 Euros, VAT included: we found a street price that moves in a relatively wide range between 429 and 315 Euros. Purchasing inevitably becomes more attractive in the lower part of the street price range or the case of particular promotions.
