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 VZ239HE from Asus.
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 VZ239HE has a display size of 23 inches ( 58.4 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 86.1 % 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 IPS panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 95 ppi. The pixel pitch is 0.265 mm. The continuous possible brightness specified by the manufacturer Asus 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. Asus promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the VZ239HE 54 khz to 85.5 khz. Vertically, however, the image renews at a minimum rate of 48 hz up to 76 hz. The analog refresh rate of this monitor is 54 khz to 85.5 khz. The frame rate in the analogue range is vertical at the VZ239HE 48 hz to 76 hz. The minimum response time of the monitor is 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 Asus 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 80000000 : 1 of dynamic contrast ratio for the monitor VZ239HE 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 monitor has a width of 53.1 cm without its attached stand/stand. The height is dimensioned at about 31.9 cm , while the for the depth of the monitor should be kept free at about 3.7 cm.
The size of the VZ239HE on the desk is likely to be particularly relevant for most users. Asus specifies a space requirement of 38.7 x 53.1 x 21.1 cm (HxWxD) with the included stand. The device weighs in total (i.e. also measured with the stand) 2.7 kg.
Rotate, tilt and swivel
The monitor from Asus cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. The monitor VZ239HE can be tilted. The angle of inclination to the rear is 22. 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: Asus '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 Asus offers a technology to reduce the blue content in its monitor VZ239HE. Game mode allows you to enjoy an enhanced gaming experience on your monitor. This mode can combine different settings on your monitor to provide a better picture and therefore an improved gaming experience.
WiFi / Bluetooth
Power consumption
On average, the monitor consumes approximately 21 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. 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
For temperature, the maximum permissible ambient temperature is 50 °C. Below a temperature of 0 °C , the monitor from Asus should again not be used. The maximum storage temperature should be according to Asus 60 °C. Minimal were given by Asus 20 °C.
Packaging
The monitor is packaged in a cardboard box measuring 50 x 59.7 x 12.5 cm (height x width x depth). The box together with the monitor weighs about 4.2 kg.
