Sony XBR-55X900H

Today we will look at the monitor XBR-55X900H from Sony 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

Let's start with the most important component of a monitor, the display. Depending on the aspect ratio of height and width, monitors can be rather wide or square, for example. Besides the pure physical dimensions, the resolution of the display and thus the quality of the display is also decisive here. For easy comparability, however, screen sizes are usually given in inches. This unit of measurement simply compares the diagonal length from the lower left to the upper right corner of the display and is thus universally applicable. This device has a screen diagonal of 54 inches ( 1.3880000000000001 m on the diagonal). While classic CRT monitors were built with a screen ratio of 4:3, this monitor has a ratio of 1.778 : 116 (width to height). In addition to the aspect ratios and the specified screen diagonal, the ratio between the monitor surface and the actual display could also be relevant for some enthusiasts. This ratio represents the general relationship between non-display and display. In other words: Approximately 94.1 % of the front surface of the monitor consists of the display, while the remaining percent consists of screen edges and is not suitable for image reproduction. If you want to place several monitors next to each other, you should make sure you choose models with the narrowest possible edges. The display is a VA panel. The panel has a resolution of 3840 x 2160 px. The pixel density is 80 ppi. The pixel pitch is 0.315 mm. The continuous possible brightness specified by the manufacturer Sony is 500 nt. The monitor's panel is characterized by its luminosity of 700 nt. 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 48 hz up to 129 hz.

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 %. The REC 2020 color space is covered to 70 %. "Calman Ready" is a certification awarded by the SpectraCal company and means that the XBR-55X900H monitor from Sony is compatible with SpectraCal's Calman software. Calman is a professional software for calibrating colors and image quality of monitors, TVs and projectors. When a monitor is designated as "Calman Ready", it means that it is capable of passing the necessary signals and information to Calman to perform accurate color correction and calibration. This feature is especially important for graphic designers, photographers, and other users who require high color accuracy and image quality.

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 4200 : 1 , according to the manufacturer.

HDR

The monitor supports all HDR modes listed here:

• HDR 10
• HDR HLG
• Dolby Vision

screen design

For the installation of the monitor, a space requirement of approximately 71 cm in height, 1.2309999999999999 m in width and 7 cm in depth is to be assumed.
If you want to place the monitor described here on the desk without a wall mount, you should allow for 78 x 1.2309999999999999 x 33.8 m (HxWxD) of space. If you want to place the monitor on a table or even transport it, you should expect a weight of 17.5 kg with the stand screwed in. According to Sony , you can expect a weight of about 16.5 kg without the stand. 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 ' XBR-55X900H ' 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

Features

AirPlay enables Apple devices to communicate wirelessly with external screens and speakers. This allows presentations, movies, games and music to be streamed to stereo or TV.

WiFi / Bluetooth

This model ( XBR-55X900H ) 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:
For a monitor, "WiFi Direct" refers to a feature that allows you to establish a direct connection between the monitor and another WLAN-enabled device without the need for a wireless network. This allows you, for example, to display content from your smartphone or tablet on the monitor without having to be near a WLAN network. The monitor XBR-55X900H supports this function as a matter of course.

Power consumption

The average consumption figure for XBR-55X900H is 173 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.

Packaging

The monitor is packaged in a cardboard box measuring 83.3 x 1.348 x 16 cm (height x width x depth). The box together with the monitor weighs about 23 kg.
