Today we will look at the monitor PB328Q from Asus from the year 2015. 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 most important component of a monitor, the display. Depending on the aspect ratio of height and width, monitors can be rather wide or square, for example. Besides the pure physical dimensions, the resolution of the display and thus the quality of the display is also decisive here. For easy comparability, however, screen sizes are usually given in inches. This unit of measurement simply compares the diagonal length from the lower left to the upper right corner of the display and is thus universally applicable. This device has a screen diagonal of 32 inches ( 81.2 cm on the diagonal). Let's keep it short and sweet. The monitor has an aspect ratio of 1.778 : 1. In addition to the aspect ratios and the specified screen diagonal, the ratio between the monitor surface and the actual display could also be relevant for some enthusiasts. This ratio represents the general relationship between non-display and display. In other words: Approximately 89.2 % of the front surface of the monitor consists of the display, while the remaining percent consists of screen edges and is not suitable for image reproduction. If you want to place several monitors next to each other, you should make sure you choose models with the narrowest possible edges. The display is a AMVA panel. The panel has a resolution of 2560 x 1440 px. The pixel density is 91 ppi. The pixel pitch is 0.277 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 PB328Q 29 khz to 130 khz. Vertically, however, the image renews at a minimum rate of 49 hz up to 76 hz. The analog refresh rate of this monitor is 30 khz to 83 khz. The frame rate in the analogue range is vertical at the PB328Q 49 hz 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.
Color space
The panel has a bit depth of 10 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 73 % according to the manufacturer. According to the manufacturer, the coverage of the SRGB color space is 100 %.
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 100000000 : 1 of dynamic contrast ratio for the monitor PB328Q 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: 43.1 cm x 73.4 cm x 6.6 cm (HxWxD)
The size of the monitor (stand included) is 61.5 x 73.4 x 24 cm (HxWxD). The device weighs in total (i.e. also measured with the stand) 11.68 kg. A height-adjustable stand ensures an improved ergonomic posture during use. The monitor can be moved to a maximum height of 15 cm. This value is always measured from the bottom edge of the screen.
The monitor, or rather the built-in OS, is controlled via a 5-way joystick. This allows navigating by moving the stick up, down, left or right. The input is usually confirmed by clicking the joystick. This input method makes it possible to change settings without having to search for different buttons under or next to the device.
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 PB328Q can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 60 degree. Pivoting to the right is possible up to 60 degree. It is possible to adjust the tilt angle of the monitor PB328Q according to personal preference to ensure ergonomic and comfortable viewing. The angle of inclination to the rear is 25. 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 3 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 by Picture mode
- 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 PB328Q.
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 AU Optronics and has the model number M320DVN01.0.
WiFi / Bluetooth
Power consumption
The maximum power consumption (peak) specified for this monitor is 2.36 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
The maximum permissible ambient temperature is 40 °C during operation. 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 55.2 x 84.7 x 35 cm (height x width x depth). The box together with the monitor weighs about 16.5 kg.
