Today we will look at the monitor Predator XB323QK NV from Acer from the year 2020. 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
Any multimedia content can be displayed on 31 inches ( 80.1 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 1.778 : 1 is sufficient. The display is a IPS panel. The panel has a resolution of 3840 x 2160 px. The pixel density is 139 ppi. The pixel pitch is 0.182 mm. The continuous possible brightness specified by the manufacturer Acer is 350 cd/m2. The monitor's panel reaches a peak brightness of 400 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. Acer promises stable color reproduction moreover within a 178 ° vertical angle. Vertically, however, the image renews at a minimum rate of 48 hz up to 144 hz. The display panel is Anti-glare/Matte. The 'Adaptive Brightness' technology of the Predator XB323QK NV monitor provides automatic adjustment of the screen brightness to enable comfortable viewing. This feature ensures that the screen always stays within a comfortable brightness range, minimizing eye strain.
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. According to the manufacturer, the coverage of the DCI-P3 color space is 90 %.
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 Acer 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 100000000 : 1 of dynamic contrast ratio for the monitor Predator XB323QK NV 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:
- HDR 400
screen design
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. The monitor has built-in RGB lighting. On some monitors, RGB lights are often used as "backlighting" or "ambient lighting". These may be placed on the back of the monitor and illuminate the screen outline or the space behind the monitor. Some monitors, on the other hand, use RGB lighting on the front or bottom of the screen to create visual effects that can be synchronized with the content being displayed.
Rotate, tilt and swivel
The monitor from Acer has a pivot function and can thus be rotated using the included stand. A rotation to the left is possible with up to 90 degree. To the right, the monitor can be rotated by 90 degree. The Predator XB323QK NV 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. It is possible to adjust the tilt angle of the monitor Predator XB323QK NV according to personal preference to ensure ergonomic and comfortable viewing. The angle of inclination to the rear is 35. The monitor can be tilted forward by 5 degree.
Ports
camera
This monitor does not have a camera.
Loudspeaker
The monitor from Acer 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 4 w power.
Features
- Flicker Free: Acer 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
- Integrated KVM Switch
- Nvidia G-SYNC
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 Acer offers a technology to reduce the blue content in its monitor Predator XB323QK NV. The Adaptive Sync feature of the Predator XB323QK NV dynamically varies the monitor's refresh rate and responds to the game's required frame rates. Unlike conventional IPS displays, the Predator XB323QK NV monitor from uses IPS panels with a fast liquid crystal technology to reduce the display's native response times. This reduction is said to make fast movements less blurry. The monitor from Predator XB323QK NV has a proximity sensor, which is normally used to detect the presence of a person or object in the immediate vicinity of the screen. This technology is commonly found in computer monitors, televisions and other display devices. The main purpose of a proximity sensor on a monitor is to save power and extend the life of the screen. When the sensor detects that no one is in front of the screen, it automatically turns off the backlight or puts the screen into a power saving mode to conserve energy. This can be especially useful if the monitor is rarely used or if it is used in a public area.
WiFi / Bluetooth
Power consumption
In standby mode, the device consumes approximately 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.
