Hitachi 55R80

Product image for 55R80

Within this article we will take a closer look at the technical specifications of the 55R80 monitor from Hitachi. For this we will talk about all possible categories that could be relevant. To start with, we will look at the display, talk about the design and in the next section we will go into the features of the monitor. Other features such as power consumption, connectors and certifications will follow later in the text.

Display

Let's start with the most important component of a monitor, the display. Depending on the aspect ratio of height and width, monitors can be rather wide or square, for example. Besides the pure physical dimensions, the resolution of the display and thus the quality of the display is also decisive here. For easy comparability, however, screen sizes are usually given in inches. This unit of measurement simply compares the diagonal length from the lower left to the upper right corner of the display and is thus universally applicable. This device has a screen diagonal of 54 inches ( 80.1 cm 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 : 1 is sufficient. 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 55R80 is a monitor with a ratio of 94.5 % between usable and non-usable front surface. The display is a VA panel. The panel has a resolution of 3840 x 2160 px. The pixel density is 124 ppi. The pixel pitch is 0.182 mm. The continuous possible brightness specified by the manufacturer Hitachi is 250 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. Hitachi promises stable color reproduction moreover within a 178 ° vertical angle. Vertically, however, the image renews at a minimum rate of 60 hz up to 60 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. According to the manufacturer, the coverage of the NTSC 1953 color space is 95 %.

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 Hitachi has a static contrast ratio of 3000 : 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 80000000 : 1 of dynamic contrast ratio for the monitor 55R80 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

Without the stand, the monitor comes with a width of 79.2 cm , a height of 49.1 cm and about 2.9 cm.
If you want to place the monitor described here on the desk without a wall mount, you should allow for 54.4 x 77.8 x 26.5 cm (HxWxD) of space. The device weighs in total (i.e. also measured with the stand) 10.6 kg. A wall mount should be designed for at least 8.75 kg to hold the 55R80 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 Hitachi cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. The monitor 55R80 can be tilted.

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 Hitachi offers a technology to reduce the blue content in its monitor 55R80.

WiFi / Bluetooth

The model 55R80 does not have Bluetooth.

Power consumption

On average, the monitor consumes approximately 57 w. The maximum power consumption (peak) specified for this monitor is 75 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. In ECO mode, the monitor consumes 42 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 3.048 km. For temperature, the maximum permissible ambient temperature is 40 °C. Below a temperature of 0 °C , the monitor from Hitachi should again not be used. The humidity must not exceed 90 percent. At least, however, 10 percent humidity. The monitor may be stored at a maximum humidity of 90 percent. The minimum humidity during storage should not fall below 5 percent. The maximum storage temperature should be according to Hitachi 60 °C. Minimal were given by Hitachi -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 61.5 x 83.8 x 28.2 cm (height x width x depth). The box together with the monitor weighs about 10.1 kg.
