Display, power consumption, dimensions, technologies used, connections, certifications, comfort features. All these keywords can be relevant for a purchase decision, but an exact comparison is often difficult. For this reason, we will summarize as many of the mentioned specifications as possible in an understandable form in the course of this article. Let's start with the most important component of the G27q-20 from Lenovo.
Display
Let's start with the size of the actual display. This is given in inches and measures the screen diagonal of the display. The monitor G27q-20 has a display size of 27 inches ( 68.5 cm on the diagonal). It should be noted, however, that displays in this category can have different dimensions, since square monitors, for example, can have the same diagonal as a widescreen monitor. 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 88.8 % 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 2560 x 1440 px. The pixel density is 109 ppi. The pixel pitch is 0.233 mm. The continuous possible brightness specified by the manufacturer Lenovo is 400 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. Vertically, however, the image renews at a minimum rate of 48 hz up to 165 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 10 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 SRGB color space is 99 %.
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 G27q-20 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
The following dimensions must be planned for a free-standing stand without attached feet/stand: 36.7 cm x 61.3 cm x 5.1 cm (HxWxD)
The size of the G27q-20 on the desk is likely to be particularly relevant for most users. Lenovo specifies a space requirement of 39.3 x 61.3 x 25.9 cm (HxWxD) with the included stand. The device weighs 6.24 kg with the stand in place. Without stand, the monitor weighs 3.98 kg. Speaking of weight without a stand and thus wall or table mounts. The monitor supports a Vesa mounting. A height-adjustable stand ensures an improved ergonomic posture during use. The monitor can be moved to a maximum height of 13 cm. This value is always measured from the bottom edge of the screen.
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. It is possible to adjust the tilt angle of the monitor G27q-20 according to personal preference to ensure ergonomic and comfortable viewing. The angle of inclination to the rear is 22. The monitor can be tilted forward by 5 degree.

Features
- Flicker Free: Lenovo 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
- AMD FreeSync Premium: By dynamically synchronizing the refresh rate of the G27q-20 with frame rate, AMD FreeSync Premium minimizes judder and ensures smooth and enjoyable gaming. In addition, AMD FreeSync Premium guarantees that the monitor operates at a minimum of 120Hz at FHD and low framerate compensation (LFC) is available.
- Nvidia G-SYNC
- 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 G27q-20.
WiFi / Bluetooth
Power consumption
The average consumption figure for G27q-20 is 32 w. The maximum power consumption (peak) specified for this monitor is 52 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. During operation, the ambient temperature must not exceed 45 °C , to ensure full functionality. 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 47.8 x 86.8 x 15.9 cm (height x width x depth). The box together with the monitor weighs about 8.55 kg.
