HP N240

Product image for N240

Today we will look at the monitor N240 from HP 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 23 inches ( 60.4 cm on the diagonal). Let's keep it short and sweet. The monitor has an aspect ratio of 1.778 : 1. In addition to the aspect ratios and the specified screen diagonal, some enthusiasts may also be interested in the ratio between the monitor surface and the actual display. This ratio describes the general relationship between non-display and display. In other words, approximately 89.7 % of the front surface of the monitor consists of the display, while the rest consists of screen edges and cannot display an image. When setting up several monitors next to each other, it is advisable to give preference to models with the narrowest possible edges. The display is a AH panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 92 ppi. The pixel pitch is 0.275 mm. The continuous possible brightness specified by the manufacturer HP 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. HP promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the N240 30 khz to 80 khz. 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. The display panel is Anti-glare/Matte.

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. According to the manufacturer, the coverage of the NTSC 1953 color space is 72 %.

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 HP has a static contrast ratio of 1000 : 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 5000000 : 1 of dynamic contrast ratio for the monitor N240 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

HP Specifies the following dimensions for the monitor N240 without stand/feet: 32.3 cm x 53.9 cm x 3.6 cm (HxWxD)
The size of the monitor (stand included) is 40.2 x 53.9 x 15.2 cm (HxWxD). The device weighs 3.4 kg with the stand in place. A wall mount should be designed for at least 2.93 kg to hold the N240 neatly and securely.

Rotate, tilt and swivel

The monitor from HP cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. Thanks to the tilt function of the N240 monitor, the screen position can be flexibly adjusted to minimize dazzling light sources and ensure optimum visibility. The angle of inclination to the rear is 22. The monitor can be tilted forward by 5 degree.

Ports

The monitor can be connected via 1 VGA ports.

camera

This monitor does not have a camera.

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 HP offers a technology to reduce the blue content in its monitor N240.

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 HP 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 LM238WF2-S5A1.

WiFi / Bluetooth

Power consumption

The average consumption was given by HP as 18 w. The maximum power consumption (peak) specified for this monitor is 20 w. In standby mode, the device consumes approximately 0.5 w. When switched off, on the other hand, the monitor consumes only 0.5 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 5 km. For temperature, the maximum permissible ambient temperature is 35 °C. Below a temperature of 5 °C , the monitor from HP should again not be used. The humidity must not exceed 80 percent. At least, however, 20 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 HP 65 °C. Minimal were given by HP -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 42 x 62 x 12.4 cm (height x width x depth). The box together with the monitor weighs about 5 kg.
