Sony KE-55A85/P

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 KE-55A85/P from Sony.

Display

The monitor belongs to the device class 54 inches ( 1.388 m on the diagonal). 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. In addition to the aspect ratios and the specified screen diagonal, some enthusiasts may also be interested in the ratio between the monitor area and the actual display. This refers to the general ratio between the non-display area and the display. In other words, approximately 94.2 % of the front surface of the monitor consists of the display, while the rest is made up of screen edges and cannot display an image. When arranging several monitors next to each other, it is advisable to choose models with the narrowest possible edges. The display is a OLED 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 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.

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.

HDR

The monitor supports all HDR modes listed here:

• HDR 10
• HDR HLG
• Dolby Vision

screen design

If you want to place the monitor described here on the desk without a wall mount, you should allow for 73.9 x 1.227 x 29.5 m (HxWxD) of space. As for the weight, Sony states a total weight of 18.2 kg with stand. According to Sony , you can expect a weight of about 16.8 kg without the stand. Speaking of weight without a stand and thus wall or table mounts. The monitor supports a Vesa mounting.

Power consumption

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.

Packaging

The monitor is packaged in a cardboard box measuring 83.2 x 1.362 x 18.4 cm (height x width x depth). The box together with the monitor weighs about 25 kg.
