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 HS221HPB from Hannspree.
Display
Let's start with the size of the actual display. This information is given in inches and measures the screen diagonal of the display. It can happen that displays with the same size specification have different dimensions, since square monitors, for example, can belong to the same category as a widescreen monitor. The monitor from Hannspree in this article has a size of 21 inches ( 54.6 cm 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 Hannspree. This monitor has an aspect ratio of 1.778 : 1. This means that every 1.778 pixels in width 1 pixels in height are added. The display is a IPS panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 102 ppi. The pixel pitch is 0.248 mm. The continuous possible brightness specified by the manufacturer Hannspree 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. Hannspree promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the HS221HPB 30 khz to 83 khz. Vertically, however, the image renews at a minimum rate of 56 hz up to 75 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 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 Hannspree 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 80000000 : 1 of dynamic contrast ratio for the monitor HS221HPB 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
The size of the HS221HPB on the desk is likely to be particularly relevant for most users. Hannspree specifies a space requirement of 37.7 x 51.1 x 18.4 cm (HxWxD) with the included stand. As for the weight, Hannspree states a total weight of 3.4 kg with stand.
Rotate, tilt and swivel
The monitor from Hannspree 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 HS221HPB 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 15. 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.
Loudspeaker
The monitor from Hannspree has integrated speakers, for playing sounds, music or speech. The sound is emitted via 2 speakers, which are integrated into the device. Each of the built-in speakers has a contingent of 1.5 w power.
Features
- The display/monitor supports Frame Rate Compensation.
WiFi / Bluetooth
Power consumption
The average consumption figure for HS221HPB is 20 w. The maximum power consumption (peak) specified for this monitor is 30 w. In standby mode, the device consumes approximately 0.28 w. When switched off, on the other hand, the monitor consumes only 0.21 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 permissible ambient temperature is 40 °C during operation. Below a temperature of 0 °C , the monitor from Hannspree should again not be used. The humidity must not exceed 90 percent. At least, however, 20 percent humidity.
