Within this article we will take a closer look at the technical specifications of the KA242YA monitor from Acer. For this we will talk about all possible categories that could be relevant. To start with, we will look at the display, talk about the design and in the next section we will go into the features of the monitor. Other features such as power consumption, connectors and certifications will follow later in the text.
Display
The monitor belongs to the device class 23 inches ( 60.4 cm on the diagonal). While classic CRT monitors were built with a screen ratio of 4:3, this monitor has a ratio of 1.778 : 1 (width to height). The display is a IPS panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 92 ppi. The pixel pitch is 0.275 mm. The continuous possible brightness specified by the manufacturer Acer is 250 cd/m2. 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. The refresh rate is horizontally seen at the KA242YA 30 khz to 85 khz. Vertically, however, the image renews at a minimum rate of 48 hz up 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.
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 KA242YA cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio. The monitor from Acer supports adaptive contrast management, dynamically adjusting the contrast ratio of the input signal to ensure razor-sharp image displays. Each scene is continuously analyzed by KA242YA and the images are adjusted accordingly frame by frame. This analysis and dynamic adjustment of contrast is designed to enhance color quality and provide better black levels when displaying dark scenes and shaded/dark image sequences.

The monitor supports all HDR modes listed here:
screen design
Rotate, tilt and swivel
The monitor from Acer cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. The monitor KA242YA offers the option of adjusting the tilt as required to create an ergonomic working environment and reduce visual fatigue. The angle of inclination to the rear is 15. 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 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 2 w power.
Features
- Flicker Free: Acer 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
- AMD FreeSync: By dynamically synchronizing the refresh rate of the KA242YA with the frame rate, AMD FreeSync minimizes judder and ensures smooth and enjoyable gameplay.
- 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 Acer offers a technology to reduce the blue content in its monitor KA242YA.
WiFi / Bluetooth
Power consumption
On average, the monitor consumes approximately 4.9 w. The maximum power consumption (peak) specified for this monitor is 28 w. In standby mode, the device consumes approximately 0.31 w. When switched off, on the other hand, the monitor consumes only 0.25 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 Acer should again not be used. The humidity must not exceed 85 percent. At least, however, 20 percent humidity.
