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 BL2381T 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 BL2381T has a display size of 22 inches ( 57.1 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. Television screens and monitors usually have an aspect ratio of 16:9 (approximately 1.78:1). More rarely, computer monitors are also found with an aspect ratio of 16:10.
Ultrawidemonitors are often manufactured with an aspect ratio of 21:9 (approximately 2.34:1). They are mainly used for computer games and as an alternative to two side-by-side screens. The first devices of this type came onto the market around 2014. Against this backdrop, the monitor BL2381T from BenQ faces an aspect ratio of 1.6 : 1. 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 84.5 % 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 IPS panel. The panel has a resolution of 1920 x 1200 px. The pixel density is 100 ppi. The pixel pitch is 0.254 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 BL2381T 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 BL2381T monitor impresses with its function called 'Adaptive Brightness'. This technology automatically adjusts the brightness of the screen to the lighting conditions of the current scene. This ensures a pleasant and eye-friendly display in various situations.
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 20000000 : 1 of dynamic contrast ratio for the monitor BL2381T 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 34.2 cm in height, 50.2 cm in width and 5.7 cm in depth is to be assumed.
The size of the monitor (stand included) is 42.8 x 50.2 x 23 cm (HxWxD). The device weighs 5.9 kg with the stand in place. According to BenQ , you can expect a weight of about 3.26 kg without the stand. A height-adjustable stand ensures an improved ergonomic posture during use. The monitor can be moved to a maximum height of 14 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 BL2381T 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. Thanks to the tilt function of the BL2381T monitor, the screen position can be flexibly adjusted to minimize dazzling light sources and ensure optimum visibility. The angle of inclination to the rear is 20. 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.
- 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 BenQ offers a technology to reduce the blue content in its monitor BL2381T.
WiFi / Bluetooth
Power consumption
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 0.5 w. In ECO mode, the monitor consumes 14 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 monitor has a built-in ambient light sensor, which can be used, for example, to dynamically adjust the brightness of the monitor to the ambient conditions. During operation, the ambient temperature must not exceed 40 °C , to ensure full functionality. Below a temperature of 0 °C , the monitor from BenQ should again not be used. The humidity must not exceed 90 percent. At least, however, 10 percent humidity.
Packaging
The box together with the monitor weighs about 7.6 kg.
