Sony KDL-75W855C

Within this article we will take a closer look at the technical specifications of the KDL-75W855C 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

The display is sized at 74 inches ( 1.893 m 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 : 116 is sufficient. Besides the aspect ratios and the specified screen diagonal, the ratio between the monitor surface and the actual display is probably also relevant for some enthusiasts. This is the general ratio of non-display to display. In other words, 95.4 % of the monitor's front area consists of the display. The remaining percent consists of screen edges and cannot display an image. If you want to place several monitors next to each other, you should make sure that the edges are as small as possible. The display is a VA panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 29 ppi. The pixel pitch is 0.865 mm. The panel is illuminated by Direct 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

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. 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 1000000 : 1 of dynamic contrast ratio for the monitor KDL-75W855C 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

For a possible wall mounting or comparison to the currently owned monitor at the beginning, the dimensions of the monitor without stand/feet: 96.9 cm x 1.6769999999999998 m x 7.9 cm (HxWxD)
The size of the KDL-75W855C on the desk is likely to be particularly relevant for most users. Sony specifies a space requirement of 1.016 x 1.6769999999999998 x 33 m (HxWxD) with the included stand. The device weighs in total (i.e. also measured with the stand) 34.9 kg. A wall mount should be designed for at least 33.7 kg to hold the KDL-75W855C neatly and securely. 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 RJ45 Ethernet port(s) on the ' KDL-75W855C ' 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

• Display of 3D content, using 3D glasses
• This monitor has an active 3D panel. Active 3D panels alternately display images intended for the right and left eye. The 3D glasses are synchronized with the panel and darken the individual lenses parallel to the image on the screen. This results in each eye seeing only the image created for that perspective and vice versa.

WiFi / Bluetooth

This model ( KDL-75W855C ) 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:
Wi-Fi Direct is supported by KDL-75W855C , 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 KDL-75W855C supports Bluetooth.

Power consumption

The average consumption figure for KDL-75W855C is 163 w. The maximum power consumption (peak) specified for this monitor is 297 w. 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.

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.
