Today we will look at the monitor LC-40UI7452E from Sharp from the year 2018. 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
The display is sized at 40 inches ( 1.102 m 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 3.2 : 1 is sufficient. Approximately 91.2 % 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 1200 px. The pixel density is 96 ppi. The pixel pitch is 0.272 mm. The continuous possible brightness specified by the manufacturer Sharp is 450 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. Sharp promises stable color reproduction moreover within a 178 ° vertical angle. Vertically, however, the image renews at a minimum rate of 50 hz up to 50 hz. The minimum response time of the monitor is ms. The display panel is Anti-glare/Matte (2H).
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. The coverage of the Adobe RGB 1998 color space is 82 % according to the manufacturer. According to the manufacturer, the coverage of the DCI-P3 color space is 57 %. According to the manufacturer, the coverage of the SRGB color space is 109 %.
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 Sharp has a static contrast ratio of 3500 : 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 100000000 : 1 of dynamic contrast ratio for the monitor LC-40UI7452E cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio.

screen design
Sharp Specifies the following dimensions for the monitor LC-40UI7452E without stand/feet: 31.6 cm x 1.01 m x 15.1 cm (HxWxD)
The size of the LC-40UI7452E on the desk is likely to be particularly relevant for most users. Sharp specifies a space requirement of 48.1 x 1.024 x 29.5 m (HxWxD) with the included stand. The device weighs 14.5 kg with the stand in place. According to Sharp , you can expect a weight of about 9 kg without the stand. 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 12 cm. This value is always measured from the bottom edge of the screen.
Curved
The LC-40UI7452E is a curved monitor with a curvature of 1.8 m
Rotate, tilt and swivel
The monitor from Sharp cannot be rotated. The LC-40UI7452E can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 135 degree. Pivoting to the right is possible up to 135 degree. The monitor LC-40UI7452E can be tilted. The angle of inclination to the rear is 32. The monitor can be tilted forward by 12 degree.

Features
- Picture by Picture mode
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 Sharp offers a technology to reduce the blue content in its monitor LC-40UI7452E.
WiFi / Bluetooth
Power consumption
The maximum power consumption (peak) specified for this monitor is 239 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 63 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
During operation, the ambient temperature must not exceed 40 °C , to ensure full functionality. Below a temperature of 10 °C , the monitor from Sharp should again not be used. The humidity must not exceed 80 percent. At least, however, 10 percent humidity. The monitor may be stored at a maximum humidity of 95 percent. The minimum humidity during storage should not fall below 5 percent. The maximum storage temperature should be according to Sharp 60 °C. Minimal were given by Sharp -20 °C.
