Display, power consumption, dimensions, technologies used, connections, certifications, comfort features. All these keywords can be relevant for a purchase decision, but an exact comparison is often difficult. For this reason, we will summarize as many of the mentioned specifications as possible in an understandable form in the course of this article. Let's start with the most important component of the KDL-49WD755 from Sony.
Display
Texts, videos and/or other applications can be displayed on the 48 inches ( 1.2309999999999999 m on the diagonal) of the monitor. As already mentioned or known, monitors have a certain number of pixels in height and width. In most cases, this is not a 1:1 ratio, which is also the case with the monitor from Sony. This monitor has an aspect ratio of 1.778 : 116. This means that every 1.778 pixels in width 116 pixels in height are added. Approximately 92.5 % of the front of the monitor is taken up by the display, while the remaining area consists of screen edges that cannot display any image information. If you want to set up several monitors next to each other, it is advisable to choose monitors with narrow edges. The display is a PLS panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 46 ppi. The pixel pitch is 0.559 mm. The continuous possible brightness specified by the manufacturer Sony is 400 nt. 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 50 hz up to 60 hz.
Color space
The panel has a bit depth of 8 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 1300 : 1 , according to the manufacturer.
HDR
The monitor supports all HDR modes listed here:
screen design
For the installation of the monitor, a space requirement of approximately 64 cm in height, 1.093 m in width and 5.6 cm in depth is to be assumed.
The size of the monitor (stand included) is 69 x 1.093 x 22.9 m (HxWxD). As for the weight, Sony states a total weight of 12 kg with stand. A wall mount should be designed for at least 11.3 kg to hold the KDL-49WD755 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 monitor named ' KDL-49WD755 ' 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
Features
WiFi / Bluetooth
This model ( KDL-49WD755 ) 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: WiFi 802.11b WiFi 802.11g WiFi 802.11n
Wi-Fi Direct is supported by KDL-49WD755 , 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 was given by Sony as 61 w. The maximum power consumption (peak) specified for this monitor is 96 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. 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, 10 percent humidity.
Packaging
The monitor is packaged in a cardboard box measuring 74.1 x 1.189 x 16.3 cm (height x width x depth). The box together with the monitor weighs about 16 kg.
