Today we will look at the monitor KDL-55W800B from Sony from the year 2018. 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 size of the actual display. This is given in inches and measures the screen diagonal of the display. The monitor KDL-55W800B has a display size of 54 inches ( 54.6 cm on the diagonal). It should be noted, however, that displays in this category can have different dimensions, since square monitors, for example, can have the same diagonal as a widescreen monitor. Television screens and monitors usually have an aspect ratio of 16:9 (approximately 1.78:1). More rarely, computer monitors are also found with an aspect ratio of 16:10.
Ultrawidemonitors are often manufactured with an aspect ratio of 21:9 (approximately 2.34:1). They are mainly used for computer games and as an alternative to two side-by-side screens. The first devices of this type came onto the market around 2014. Against this backdrop, the monitor KDL-55W800B from Sony faces an aspect ratio of 1.778 : 116. If you want to pay attention to special aesthetics or simply want to place several monitors next to each other, you should pay attention to the ratio between display and non-display. The KDL-55W800B is a monitor with a ratio of 99 % between usable and non-usable front surface. The display is a VA panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 92 ppi. The pixel pitch is 0.248 mm. The continuous possible brightness specified by the manufacturer Sony is 400 nt. 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. Sony promises stable color reproduction moreover within a 178 ° vertical angle. Vertically, however, the image renews at a minimum rate of 50 hz up to 50 hz. The minimum response time of the monitor is ms. The display panel is Anti-glare/Matte (3H).
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.
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 1200 : 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 20000000 : 1 of dynamic contrast ratio for the monitor KDL-55W800B cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio.

screen design
Sony Specifies the following dimensions for the monitor KDL-55W800B without stand/feet: 32.9 cm x 55.2 cm x 5.7 cm (HxWxD)
If you want to place the monitor described here on the desk without a wall mount, you should allow for 34.2 x 45.1 x 16.1 cm (HxWxD) of space. If you want to place the monitor on a table or even transport it, you should expect a weight of 6 kg with the stand screwed in. A wall mount should be designed for at least 4.04 kg to hold the KDL-55W800B 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. The monitor KDL-55W800B can be tilted. The angle of inclination to the rear is 32. The monitor can be tilted forward by 12 degree.
Ports
The monitor can be connected via 1 VGA ports.
camera
This monitor does not have a camera.

Features
- 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 Sony offers a technology to reduce the blue content in its monitor KDL-55W800B.
WiFi / Bluetooth
Power consumption
On average, the monitor consumes approximately 28.6 w. The maximum power consumption (peak) specified for this monitor is 40.15 w. In standby mode, the device consumes approximately 0.5 w. When switched off, on the other hand, the monitor consumes only 0.3 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 height at which the monitor may be operated, according to the manufacturer's specifications, is 3.658 km. For temperature, the maximum permissible ambient temperature is 40 °C. 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, 20 percent humidity. The monitor may be stored at a maximum humidity of 80 percent. The minimum humidity during storage should not fall below 20 percent. The maximum storage temperature should be according to Sony 60 °C. Minimal were given by Sony -20 °C. According to the manufacturer, the monitor may be stored at a maximum height of 12.192 km.
Packaging
The monitor is packaged in a cardboard box measuring 43.4 x 56.5 x 15.3 cm (height x width x depth). The box together with the monitor weighs about 4.17 kg.
