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 27x from HP.
Display
The display is sized at 27 inches ( 68.5 cm on the diagonal). The size specification of a monitor refers to the screen diagonal, which is usually specified in inches. It is only comparable to a limited extent for different formats. For example, a conventional 4:3 monitor with the same screen diagonal has 6% less width, but 13% more height and a total of 7% more surface area than a monitor in 16:10 format. Despite the difference in working area, wider monitors are better suited for consuming games or current movies, for example. It is also easier to display several documents simultaneously on widescreen monitors. So, it depends on the current use case whether the aspect ratio of 1.778 : 1 makes sense for the intended use case. In addition to the aspect ratios and the specified screen diagonal, the ratio between the monitor surface and the actual display could also be important for some enthusiasts. This ratio describes the general relationship between the non-display area and the display. In other words, approximately 90 % of the front surface of the monitor consists of the display, while the remaining percent consists of screen edges and does not enable image reproduction. When setting up several monitors next to each other, it is advisable to prefer models with the narrowest possible edges. The display is a VA 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 HP 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. HP promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the 27x 170 khz to 170 khz. Vertically, however, the image renews at a minimum rate of 144 hz up to 144 hz. The minimum response time of the monitor is 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 SRGB color space is 99 %.
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 3000 : 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 10000000 : 1 of dynamic contrast ratio for the monitor 27x 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
For the installation of the monitor, a space requirement of approximately 36.3 cm in height, 61.3 cm in width and 6.9 cm in depth is to be assumed.
The size of the monitor (stand included) is 43.8 x 61.3 x 17.9 cm (HxWxD). The device weighs in total (i.e. also measured with the stand) 5.2 kg. A wall mount should be designed for at least 5 kg to hold the 27x neatly and securely.
Curved
The 27x is a curved monitor with a curvature of 1.8 m
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. It is possible to adjust the tilt angle of the monitor 27x according to personal preference to ensure ergonomic and comfortable viewing. The angle of inclination to the rear is 25. The monitor can be tilted forward by 5 degree.
Ports
camera
This monitor does not have a camera.
Loudspeaker
Features
- AMD FreeSync: By dynamically synchronizing the refresh rate of the 27x with the frame rate, AMD FreeSync minimizes judder and ensures smooth and enjoyable gameplay.
WiFi / Bluetooth
Power consumption
The average consumption was given by HP as 39 w. The maximum power consumption (peak) specified for this monitor is 47 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 permissible ambient temperature is 40 °C during operation. Below a temperature of 0 °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 90 percent. The minimum humidity during storage should not fall below 10 percent. The maximum storage temperature should be according to HP 65 °C. Minimal were given by HP -20 °C.
