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 G2250 from BenQ.
Display
The monitor belongs to the device class 21 inches ( 54.6 cm on the diagonal). As already known, two monitors with different outer dimensions can have the same screen diagonal. In the case of the monitor G2250 , we find an aspect ratio of 1.778 to 1. This means that for every 1 pixels in height, 1.778 pixels in width are added. For comparison: A classic CRT monitor had an aspect ratio of 4:3. Besides the aspect ratios and the specified screen diagonal, the ratio between the monitor surface and the actual display is probably also relevant for some enthusiasts. This is the general ratio of non-display to display. In other words, 76.1 % of the monitor's front area consists of the display. The remaining percent consists of screen edges and cannot display an image. If you want to place several monitors next to each other, you should make sure that the edges are as small as possible. The display is a TN panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 102 ppi. The pixel pitch is 0.248 mm. The continuous possible brightness specified by the manufacturer BenQ is 300 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 170 ° (horizontal) viewing angle. BenQ promises stable color reproduction moreover within a 160 ° vertical angle. The refresh rate is horizontally seen at the G2250 30 khz to 83 khz. Vertically, however, the image renews at a minimum rate of 50 hz up to 76 hz. The minimum response time of the monitor is ms. The average response time of the monitor is about ms.
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 BenQ 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 50000 : 1 of dynamic contrast ratio for the monitor G2250 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
BenQ Specifies the following dimensions for the monitor G2250 without stand/feet: 31.9 cm x 52.4 cm x 6 cm (HxWxD)
If you want to place the monitor described here on the desk without a wall mount, you should allow for 39.9 x 52.4 x 17.3 cm (HxWxD) of space. If you want to place the monitor on a table or even transport it, you should expect a weight of 4.1 kg with the stand screwed in.
Rotate, tilt and swivel
The monitor from BenQ cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. The tilt of the monitor G2250 can be individually adjusted to optimize the viewing angle and increase comfort during use. The angle of inclination to the rear is 15. 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.
Loudspeaker
Features
- Flicker Free: BenQ 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
- The display/monitor supports Frame Rate Compensation.
Panel manufacturer
Many manufacturers of monitors and TVs fall back on third-party manufacturers, such as Samsung or LG, when choosing the actual display (panel). Thus, many of the monitors have the same panel and, conversely, differ only in their design, additional functionalities, the software used and, of course, the price. Two monitors from BenQ or another manufacturer with an identical panel do not necessarily have to have the same picture quality, but it is usually a first indicator for a purchase decision. The panel used here is originally from AU Optronics and has the model number M215HW03 V1.
WiFi / Bluetooth
Power consumption
The maximum power consumption (peak) specified for this monitor is 43 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 permissible ambient temperature is 40 °C during operation. Below a temperature of 5 °C , the monitor from BenQ should again not be used. The maximum storage temperature should be according to BenQ 60 °C. Minimal were given by BenQ -20 °C.
