Today we will look at the monitor GW2250HM from BenQ from the year 2012. 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
Let's start with the size of the actual display. This information is given in inches and measures the screen diagonal of the display. It can happen that displays with the same size specification have different dimensions, since square monitors, for example, can belong to the same category as a widescreen monitor. The monitor from BenQ in this article has a size of 21 inches ( 54.6 cm on the diagonal). The size specification of a monitor refers to the screen diagonal, which is usually specified in inches. It is only comparable to a limited extent for different formats. For example, a conventional 4:3 monitor with the same screen diagonal has 6% less width, but 13% more height and a total of 7% more surface area than a monitor in 16:10 format. Despite the difference in working area, wider monitors are better suited for consuming games or current movies, for example. It is also easier to display several documents simultaneously on widescreen monitors. So, it depends on the current use case whether the aspect ratio of 1.778 : 1 makes sense for the intended use case. In addition to the aspect ratios and the specified screen diagonal, some enthusiasts may also be interested in the ratio between the monitor area and the actual display. This refers to the general ratio between the non-display area and the display. In other words, approximately 76 % of the front surface of the monitor consists of the display, while the rest is made up of screen edges and cannot display an image. When arranging several monitors next to each other, it is advisable to choose models with the narrowest possible edges. The display is a VA 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 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. BenQ promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the GW2250HM 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 maximum 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 5000 : 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 20000000 : 1 of dynamic contrast ratio for the monitor GW2250HM 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 GW2250HM without stand/feet: 32 cm x 52.5 cm x 6.3 cm (HxWxD)
The size of the monitor (stand included) is 40 x 52.5 x 17.6 cm (HxWxD). The device weighs 3.8 kg with the stand in place.
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 GW2250HM 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
The monitor from BenQ has integrated speakers, for playing sounds, music or speech. The sound is emitted via 2 speakers, which are integrated into the device. Each of the built-in speakers has a contingent of 1 w power.
Features
- Flicker Free: BenQ 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
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 M215HW02 V0.
WiFi / Bluetooth
Power consumption
The average consumption figure for GW2250HM is 27 w. The maximum power consumption (peak) specified for this monitor is 35 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
During operation, the ambient temperature must not exceed 40 °C , to ensure full functionality. 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.
