Sony KD-55X750F

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 KD-55X750F from Sony.

Display

Any multimedia content can be displayed on 54 inches ( 1.388 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). Approximately 91.9 % 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 IPS panel. The panel has a resolution of 3840 x 2160 px. The pixel density is 81 ppi. The pixel pitch is 0.315 mm. The continuous possible brightness specified by the manufacturer Sony is 300 nt. The maximum brightness of the monitor is 400 nt on the panel. 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 50 hz up to 60 hz. The minimum response time of the monitor is ms. The average response time of the monitor is about 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. According to the manufacturer, the coverage of the DCI-P3 color space is 80 %. The REC 2020 color space is covered to 60 %.

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 1000 : 1 , according to the manufacturer.

HDR

The monitor supports all HDR modes listed here:

• HDR 10
• HDR HLG

screen design

Without the stand, the monitor comes with a width of 1.242 m , a height of 72.1 cm and about 8 cm.
If you want to place the monitor described here on the desk without a wall mount, you should allow for 78.4 x 1.242 x 35.6 m (HxWxD) of space. If you want to place the monitor on a table or even transport it, you should expect a weight of 17.4 kg with the stand screwed in. Without stand, the monitor weighs 16.2 kg. 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 ' KD-55X750F ' 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

• The display/monitor supports Frame Rate Compensation.

WiFi / Bluetooth

This model ( KD-55X750F ) 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 KD-55X750F , 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. The KD-55X750F supports Bluetooth.

Power consumption

The average consumption figure for KD-55X750F is 140 w. The maximum power consumption (peak) specified for this monitor is 180 w. In standby mode, the device consumes approximately 0.5 w. In ECO mode, the monitor consumes 65 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. During operation, the ambient temperature must not exceed 40 °C , to ensure full functionality. 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.
