Today we will look at the monitor CG248-4K from EIZO from the year 2015. 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
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 23 inches ( 60.4 cm on the diagonal). Television screens and monitors usually have an aspect ratio of 16:9 (approximately 1.78:1). More rarely, computer monitors are also found with an aspect ratio of 16:10.
Ultrawidemonitors are often manufactured with an aspect ratio of 21:9 (approximately 2.34:1). They are mainly used for computer games and as an alternative to two side-by-side screens. The first devices of this type came onto the market around 2014. Against this backdrop, the monitor CG248-4K from EIZO faces an aspect ratio of 1.778 : 1. Approximately 81.9 % of the front surface of the monitor is covered by the display, while the remaining area consists of screen edges that do not allow any image output. If you want to set up several monitors next to each other, it is advisable to prefer models with the narrowest possible edges. The display is a IPS panel. The panel has a resolution of 3840 x 2160 px. The pixel density is 185 ppi. The pixel pitch is 0.137 mm. The continuous possible brightness specified by the manufacturer EIZO is 350 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. EIZO promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the CG248-4K 24.5 khz to 137.5 khz. Vertically, however, the image renews at a minimum rate of 22.5 hz up to 71.5 hz. The minimum response time of the monitor is ms. The maximum response time of the monitor is ms. The average response time of the monitor is about 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. The coverage of the Adobe RGB 1998 color space is 99 % according to the manufacturer. According to the manufacturer, the coverage of the DCI-P3 color space is 93 %. According to the manufacturer, the coverage of the NTSC 1953 color space is 108 %. According to the manufacturer, the coverage of the SRGB color space is 100 %.
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 EIZO has a static contrast ratio of 1000 : 1 , according to the manufacturer.

The monitor supports all HDR modes listed here:
screen design
Without the stand, the monitor comes with a width of 55.3 cm , a height of 34.5 cm and about 6.4 cm.
If you want to place the monitor described here on the desk without a wall mount, you should allow for 39.4 x 55.3 x 24.5 cm (HxWxD) of space. The device weighs in total (i.e. also measured with the stand) 8.5 kg. A wall mount should be designed for at least 5.7 kg to hold the CG248-4K neatly and securely. Speaking of weight without a stand and thus wall or table mounts. The monitor supports a Vesa mounting. A height-adjustable stand ensures an improved ergonomic posture during use. The monitor can be moved to a maximum height of 15 cm. This value is always measured from the bottom edge of the screen.
Rotate, tilt and swivel
The monitor from EIZO has a pivot function and can thus be rotated using the included stand. A rotation to the left is possible with up to 0 degree. To the right, the monitor can be rotated by 90 degree. The CG248-4K can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 172 degree. Pivoting to the right is possible up to 172 degree. The monitor CG248-4K offers the option of adjusting the tilt as required to create an ergonomic working environment and reduce visual fatigue. The angle of inclination to the rear is 35. The monitor can be tilted forward by 5 degree.

Features
- Flicker Free: EIZO 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
- The display/monitor supports Frame Rate Compensation.
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 EIZO 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 LG Display and has the model number LM238WR2-SLC1.
WiFi / Bluetooth
Power consumption
The average consumption was given by EIZO as 52 w. The maximum power consumption (peak) specified for this monitor is 136 w. In standby mode, the device consumes approximately 9 w. In ECO mode, the monitor consumes 36 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. There are 1.45 amps specified. The power grid has to supply a frequency of 50 hz to 60 hz.
Environment
The maximum permissible ambient temperature is 35 °C during operation. Below a temperature of 0 °C , the monitor from EIZO should again not be used. The humidity must not exceed 80 percent. At least, however, 20 percent humidity. The maximum storage temperature should be according to EIZO 60 °C. Minimal were given by EIZO -20 °C.
