Within this article we will take a closer look at the technical specifications of the KD-55XD8577 monitor from Sony. 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
Videos and/or other applications can be displayed on the monitor's 54 inches ( 1.3880000000000001 m on the diagonal). As already mentioned or known, monitors have a certain number of pixels in height and width. In most cases, this is not a 1:1 ratio, which is also the case with the monitor from Sony. This monitor has an aspect ratio of 1.778 : 116. This means that every 1.778 pixels in width 116 pixels in height are added. In addition to the aspect ratios and the specified screen diagonal, the ratio between the monitor surface and the actual display could also be important for some enthusiasts. This ratio describes the general relationship between the non-display area and the display. In other words, approximately 93.2 % of the front surface of the monitor consists of the display, while the remaining percent consists of screen edges and does not enable image reproduction. When setting up several monitors next to each other, it is advisable to prefer models with the narrowest possible edges. The display is a IPS panel. The panel has a resolution of 3840 x 2160 px. The pixel density is 81 ppi. The pixel pitch is 0.315 mm. The continuous possible brightness specified by the manufacturer Sony is 400 nt. The panel is illuminated by Edge 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. Sony promises stable color reproduction moreover within a 178 ° vertical angle. Vertically, however, the image renews at a minimum rate of 100 hz up to 120 hz. The minimum response time of the monitor is ms.
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 86 %. The REC 2020 color space is covered to 64 %.
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 Sony has a static contrast ratio of 1500 : 1 , according to the manufacturer.
HDR
The monitor supports all HDR modes listed here:
- HDR
- HDR HLG
screen design
The monitor has a width of 1.2309999999999999 m without its attached stand/stand. The height is dimensioned at about 71.7 cm , while the for the depth of the monitor should be kept free at about 4.4 cm.
The size of the monitor (stand included) is 77 x 1.2309999999999999 x 26.3 m (HxWxD). As for the weight, Sony states a total weight of 18.6 kg with stand. The monitor KD-55XD8577 without the stand weighs 15.1 kg. This weight reduction should be taken into account for wall or arm mounting, since monitor arms have a maximum load capacity. Speaking of weight without a stand and thus wall or table mounts. The monitor supports a Vesa mounting.
Rotate, tilt and swivel
The monitor from Sony cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. A tilt function was not provided by Sony with the included stand.
Ports
With the built-in 1 RJ45 Ethernet port(s) on the ' KD-55XD8577 ' monitor, users can establish a wired network connection. This feature provides a stable connectivity option for those who need a reliable network connection, whether for professional tasks or mission-critical applications.
camera
This monitor does not have a camera.
Loudspeaker
Features
- The display/monitor supports Frame Rate Compensation.
WiFi / Bluetooth
This model ( KD-55XD8577 ) supports Wi-Fi. This wireless network connection allows devices to display content from a smartphone or tablet, for example, or to download apps from an app store, similar to TVs. However, monitors usually do not have this functionality because they are only operated in connection with a notebook or PC. The protocols are supported: WiFi 802.11a WiFi 802.11ac WiFi 802.11b WiFi 802.11g WiFi 802.11n
Wi-Fi Direct is supported by KD-55XD8577 , which is a standard for data transfer between two WLAN devices without a central wireless access point. This functionality makes it possible, for example, to send and display pictures and videos directly to the monitor without a Wi-Fi connection to the router. The KD-55XD8577 supports Bluetooth.
Power consumption
The average consumption was given by Sony as 103 w. The maximum power consumption (peak) specified for this monitor is 157 w. In standby mode, the device consumes approximately 0.5 w. 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 monitor has a built-in ambient light sensor, which can be used, for example, to dynamically adjust the brightness of the monitor to the ambient conditions. The maximum permissible ambient temperature is 40 °C during operation. Below a temperature of 0 °C , the monitor from Sony should again not be used. The humidity must not exceed 80 percent. At least, however, 10 percent humidity.
