Today we will look at the monitor VN289QL from Asus from the year 2013. 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
The display is sized at 28 inches ( 71.1 cm on the diagonal). For books or documents, a portrait format layout is usually used because the reading flow decreases as the width of the text increases. For small diagonals, screens in 4:3 format have a clear advantage because they are better suited for display due to their height. In contrast, widescreen monitors are better suited for playing video games or displaying several documents side by side, for example. Depending on the application, it should be decided individually whether the aspect ratio of 1.6 : 1 is sufficient. Around 84.3 % of the front surface of the monitor consists of the display, while the rest is made up of screen edges that cannot display images. If you want to place several monitors next to each other, it is advisable to prefer those with narrow edges. The display is a MVA panel. The panel has a resolution of 1920 x 1200 px. The pixel density is 78 ppi. The pixel pitch is 0.323 mm. The continuous possible brightness specified by the manufacturer Asus 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 178 ° (horizontal) viewing angle. Asus promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the VN289QL 30 khz to 80 khz. Vertically, however, the image renews at a minimum rate of 50 hz up to 75 hz. The analog refresh rate of this monitor is 30 khz to 80 khz. The frame rate in the analogue range is vertical at the VN289QL 50 hz to 75 hz. The minimum response time of the monitor is ms. The display panel is Anti-glare/Matte.
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. The coverage of the Adobe RGB 1998 color space is 67 % according to the manufacturer. According to the manufacturer, the coverage of the NTSC 1953 color space is 72 %. According to the manufacturer, the coverage of the SRGB color space is 92 %.
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 3000 : 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 VN289QL 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 following dimensions must be planned for a free-standing stand without attached feet/stand: 38 cm x 66 cm x 6.3 cm (HxWxD)
If you want to place the monitor described here on the desk without a wall mount, you should allow for 42.5 x 66 x 24.7 cm (HxWxD) of space. The device weighs in total (i.e. also measured with the stand) 5.4 kg. A height-adjustable stand ensures an improved ergonomic posture during use. The monitor can be moved to a maximum height of 13 cm. This value is always measured from the bottom edge of the screen.
Rotate, tilt and swivel
The monitor from Asus 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 VN289QL can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 160 degree. Pivoting to the right is possible up to 160 degree. The tilt of the monitor VN289QL can be individually adjusted to optimize the viewing angle and increase comfort during use. 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 Asus 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: Asus 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
- Picture in Picture mode
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 VN289QL.
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 Asus 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 Innolux and has the model number M280HKJ-L30.
WiFi / Bluetooth
Power consumption
The average consumption figure for VN289QL is 35 w. In standby mode, the device consumes approximately 0.5 w. When switched off, on the other hand, the monitor consumes only 0.5 w. In ECO mode, the monitor consumes 20 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.
