Today we will look at the monitor L27i-30 from Lenovo from the year 2021. Within this article, we will first take a closer look at the most important feature of a monitor -the display-, then the design, and in the next section we will go into the features of the monitor. Of course, power consumption, certifications, connectivity and other important details will also be considered.
Display
According to the manufacturer, the display measures 27 inches ( 68.5 cm on the diagonal). While classic CRT monitors were built with a screen ratio of 4:3, this monitor has a ratio of 1.778 : 1 (width to height). Approximately 89.2 % of the front surface of the monitor is covered by the display, while the remaining area consists of screen edges that do not allow any image output. If you want to set up several monitors next to each other, it is advisable to prefer models with the narrowest possible edges. The display is a IPS panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 81 ppi. The pixel pitch is 0.311 mm. The continuous possible brightness specified by the manufacturer Lenovo is 250 nt. The panel is illuminated by W-LED. The built-in panel ensures stable color reproduction of the image, even at deviating viewing angles, by means of its 178 ° (horizontal) viewing angle. Lenovo promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the L27i-30 30 khz to 83 khz. Vertically, however, the image renews at a minimum rate of 48 hz up to 75 hz. The minimum response time of the monitor is ms. The average response time of the monitor is about ms. The display panel is Anti-glare/Matte.
Color space
The panel has a bit depth of 8 per color channel, but what does that mean? The number of bits determines how many colors can be encoded for the individual pixels of the display. For an 8-bit panel, for example, this is 256 different colors (2^8 = 256). However, since we usually display three different colors per pixel at the same time, in theory about 16 million (256^3) different colors are possible by mixing the three pixels. A 10-bit panel could even display a billion colors. According to the manufacturer, the coverage of the NTSC 1953 color space is 72 %.
Contrast ratio
Contrast ratio is a common measurement used to represent the maximum relative differences in brightness between black and white. It describes the ability of a screen or projector to produce a high-contrast image and is the quotient of the maximum and minimum displayable luminance. The higher the values are away from each other, the stronger the quantitatively seen difference between black and white is set up, which in turn results in an improved image quality. This monitor from Lenovo has a static contrast ratio of 1000 : 1 , according to the manufacturer. In contrast to the static contrast ratio, the dynamic contrast ratio changes the brightness of the panel itself in addition to the difference measurement from black to white. In addition to the difference between the brightest and the darkest pixel, the backlight is thus changed. Since the brightness of the panel may not be able to be adjusted exactly to a single pixel, a so-called halo effect is possible. The value of 3000000 : 1 of dynamic contrast ratio for the monitor L27i-30 cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio.
HDR
The monitor supports all HDR modes listed here:
screen design
Lenovo Specifies the following dimensions for the monitor L27i-30 without stand/feet: 36.7 cm x 61.2 cm x 4.3 cm (HxWxD)
The size of the monitor (stand included) is 47.5 x 61.2 x 17.5 cm (HxWxD). The device weighs 4.41 kg with the stand in place. According to Lenovo , you can expect a weight of about 3.6 kg without the stand. Speaking of weight without a stand and thus wall or table mounts. The monitor supports a Vesa mounting.
Rotate, tilt and swivel
The monitor from Lenovo cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. The monitor L27i-30 offers the option of adjusting the tilt as required to create an ergonomic working environment and reduce visual fatigue. The angle of inclination to the rear is 22. The monitor can be tilted forward by 5 degree.
Ports
The monitor can be connected via 1 VGA ports.
camera
This monitor does not have a camera.

Features
- Flicker Free: Lenovo 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
- AMD FreeSync: By dynamically synchronizing the refresh rate of the L27i-30 with the frame rate, AMD FreeSync minimizes judder and ensures smooth and enjoyable gameplay.
- The display/monitor supports Frame Rate Compensation.
Anyone who works a lot on the computer spends many hours a day in front of the screen. Excessive screen work can damage the eyes. This effect can be particularly pronounced during the darker hours and in the winter months. Many monitor manufacturers have now reacted and offer technologies and settings to reduce the blue component, which is primarily controversial. Depending on the manufacturer, these can be called "Low Blue Light", "Low Blue Light Technology", "SoftBlue" or even "Eye Saver Mode" and function differently. However, it is only important that Lenovo offers a technology to reduce the blue content in its monitor L27i-30.
WiFi / Bluetooth
Power consumption
The average consumption figure for L27i-30 is 18 w. The maximum power consumption (peak) specified for this monitor is 24 w. In standby mode, the device consumes approximately 0.5 w. When switched off, on the other hand, the monitor consumes only 0.3 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. The power grid has to supply a frequency of 50 hz to 60 hz.
Environment
The maximum height at which the monitor may be operated, according to the manufacturer's specifications, is 5 km. The maximum permissible ambient temperature is 45 °C during operation. Below a temperature of 0 °C , the monitor from Lenovo should again not be used. The humidity must not exceed 80 percent. At least, however, 10 percent humidity. The monitor may be stored at a maximum humidity of 95 percent. The minimum humidity during storage should not fall below 5 percent. The maximum storage temperature should be according to Lenovo 60 °C. Minimal were given by Lenovo -20 °C. According to the manufacturer, the monitor may be stored at a maximum height of 12.192 km.
Packaging
The monitor is packaged in a cardboard box measuring 45.5 x 71 x 12.6 cm (height x width x depth). The box together with the monitor weighs about 6.23 kg.
