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 GL2450HT from BenQ.
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 GL2450HT has a display size of 24 inches ( 61.1 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. 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. Approximately 78.3 % of the front surface of the monitor is taken up by the display, while the remaining part is screen edges that do not allow the image to be displayed. If you want to place several monitors next to each other, it is advisable to choose models with narrow edges. The display is a TN panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 91 ppi. The pixel pitch is 0.277 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 170 ° (horizontal) viewing angle. BenQ promises stable color reproduction moreover within a 160 ° vertical angle. The refresh rate is horizontally seen at the GL2450HT 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. The display panel is Anti-glare/Matte (3H).
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 12000000 : 1 of dynamic contrast ratio for the monitor GL2450HT 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
For the installation of the monitor, a space requirement of approximately 35 cm in height, 57.9 cm in width and 6.3 cm in depth is to be assumed.
The size of the GL2450HT on the desk is likely to be particularly relevant for most users. BenQ specifies a space requirement of 39.2 x 57.9 x 21.3 cm (HxWxD) with the included stand. The device weighs in total (i.e. also measured with the stand) 5.1 kg. A height-adjustable stand ensures an improved ergonomic posture during use. The monitor can be moved to a maximum height of 11 cm. This value is always measured from the bottom edge of the screen.
Rotate, tilt and swivel
The monitor from BenQ has a pivot function and can thus be rotated using the included stand. A rotation to the left is possible with up to 0 degree. To the right, the monitor can be rotated by 90 degree. The GL2450HT can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 45 degree. Pivoting to the right is possible up to 45 degree. The monitor GL2450HT can be tilted. 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. There are 1 HDMI ports on the monitor.
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 2 w power.
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 M240HTN01.2.
WiFi / Bluetooth
Power consumption
The average consumption figure for GL2450HT is 23 w. The maximum power consumption (peak) specified for this monitor is 42 w. In standby mode, the device consumes approximately 0.5 w. When switched off, on the other hand, the monitor consumes only 0.2 w. In ECO mode, the monitor consumes 10 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 humidity must not exceed 90 percent. At least, however, 20 percent humidity. The monitor may be stored at a maximum humidity of 90 percent. The minimum humidity during storage should not fall below 10 percent. The maximum storage temperature should be according to BenQ 60 °C. Minimal were given by BenQ -20 °C.
