Sony KJ-85Z9H

Within this article we will take a closer look at the technical specifications of the KJ-85Z9H 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

Texts, videos and/or other applications can be displayed on the 84 inches ( 2.14 m on the diagonal) of the monitor. 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. Approximately 90.3 % of the front surface of the monitor is taken up by the display, while the remaining part is screen edges that do not allow the image to be displayed. If you want to place several monitors next to each other, it is advisable to choose models with narrow edges. The display is a VA panel. The panel has a resolution of 7680 x 4320 px. The pixel density is 104 ppi. The pixel pitch is 0.244 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.

Color representation

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.

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.

HDR

The monitor supports all HDR modes listed here:

• HDR 10
• HDR HLG
• Dolby Vision

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: 1.141 m x 1.913 m x 12 cm (HxWxD)
The size of the monitor (stand included) is 1.226 x 1.913 x 43.2 m (HxWxD). The device weighs in total (i.e. also measured with the stand) 75.8 kg. A wall mount should be designed for at least 73 kg to hold the KJ-85Z9H 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

The ' KJ-85Z9H ' monitor is equipped with 1 RJ45 Ethernet port(s) that allow direct connection to wired networks. This feature opens up the possibility for users to benefit from a stable and potentially higher network speed, especially in situations where a reliable Internet connection is essential.

camera

This monitor does not have a camera.

Loudspeaker

The monitor from Sony has integrated speakers, for playing sounds, music or speech. The sound is emitted via 4 speakers, which are integrated into the device. Each of the built-in speakers has a contingent of 5 w power. The monitor has an integrated subwoofer. In total, the subwoofer consists of 4 driver(s). Each of the built-in drivers has a capacity of 5 w.

WiFi / Bluetooth

This model ( KJ-85Z9H ) 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 KJ-85Z9H , 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.

Power consumption

The maximum power consumption (peak) specified for this monitor is 945 w. In standby mode, the device consumes approximately 0.5 w. The monitor can be operated on a 110v power supply. The power grid has to supply a frequency of 50 hz to 60 hz.

Packaging

The monitor is packaged in a cardboard box measuring 1.29 x 2.08 x 43 cm (height x width x depth). The box together with the monitor weighs about 95 kg.
