Today we will look at the monitor HS278UPB from Hannspree from the year 2017. 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
According to the manufacturer, the display measures 27 inches ( 68.5 cm on the diagonal). While classic CRT monitors were built with a screen ratio of 4:3, this monitor has a ratio of 1.778 : 1 (width to height). The display is a IPS panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 81 ppi. The pixel pitch is 0.311 mm. The continuous possible brightness specified by the manufacturer Hannspree is 300 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 HS278UPB 24 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 HS278UPB 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 HS278UPB on the desk is likely to be particularly relevant for most users. Hannspree specifies a space requirement of 44.7 x 64.6 x 21.9 cm (HxWxD) with the included stand. If you want to place the monitor on a table or even transport it, you should expect a weight of 5.2 kg with the stand screwed in.
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. The monitor HS278UPB can be tilted. The angle of inclination to the rear is 20. 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 2 w power.
Features
- The display/monitor supports Frame Rate Compensation.
WiFi / Bluetooth
Power consumption
The average consumption figure for HS278UPB is 26 w. The maximum power consumption (peak) specified for this monitor is 41 w. In standby mode, the device consumes approximately 0.5 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
For temperature, the maximum permissible ambient temperature is 40 °C. 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.
