Sony KDL-55W829B

Today we will look at the monitor KDL-55W829B from Sony from the year 2014. 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

The monitor belongs to the device class 54 inches ( 1.388 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. Around 92.3 % of the front surface of the monitor consists of the display, while the rest is made up of screen edges that cannot display images. If you want to place several monitors next to each other, it is advisable to prefer those with narrow edges. The display is a AMVA panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 40 ppi. The pixel pitch is 0.63 mm. 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 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. This monitor from Sony has a static contrast ratio of 4000 : 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 1000000 : 1 of dynamic contrast ratio for the monitor KDL-55W829B 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

The following dimensions must be planned for a free-standing stand without attached feet/stand: 72.2 cm x 1.234 m x 6.5 cm (HxWxD)
The size of the KDL-55W829B on the desk is likely to be particularly relevant for most users. Sony specifies a space requirement of 76.4 x 1.234 x 19.7 m (HxWxD) with the included stand. If you want to place the monitor on a table or even transport it, you should expect a weight of 18 kg with the stand screwed in. The monitor KDL-55W829B without the stand weighs 17.2 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

The monitor named ' KDL-55W829B ' has 1 RJ45 Ethernet port(s), which enables a wired network connection. This port offers users the possibility to connect the device directly to a wired network, which can be beneficial in environments with a reliable and fast internet connection.

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 2 speakers, which are integrated into the device. Each of the built-in speakers has a contingent of 10 w power.

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.

Panel manufacturer

Many manufacturers of monitors and TVs fall back on third-party manufacturers, such as Samsung or LG, when choosing the actual display (panel). Thus, many of the monitors have the same panel and, conversely, differ only in their design, additional functionalities, the software used and, of course, the price. Two monitors from Sony or another manufacturer with an identical panel do not necessarily have to have the same picture quality, but it is usually a first indicator for a purchase decision. The panel used here is originally from AU Optronics and has the model number T550HVN06.0.

WiFi / Bluetooth

This model ( KDL-55W829B ) 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-55W829B , 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 average consumption figure for KDL-55W829B is 61 w. The maximum power consumption (peak) specified for this monitor is 101 w. In standby mode, the device consumes approximately 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 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.
