Today we will look at the monitor Omen 27i from HP from the year 2020. 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
Texts, videos and/or other applications can be displayed on the 27 inches ( 68.4 cm on the diagonal) of the monitor. 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 HP. 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. Besides the aspect ratios and the specified screen diagonal, the ratio between the monitor surface and the actual display is probably also relevant for some enthusiasts. This is the general ratio of non-display to display. In other words, 89 % of the monitor's front area consists of the display. The remaining percent consists of screen edges and cannot display an image. If you want to place several monitors next to each other, you should make sure that the edges are as small as possible. The display is a IPS panel. The panel has a resolution of 2560 x 1440 px. The pixel density is 109 ppi. The pixel pitch is 0.233 mm. The continuous possible brightness specified by the manufacturer HP is 350 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 Omen 27i 80 khz to 250 khz. Vertically, however, the image renews at a minimum rate of 48 hz up to 165 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 10 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 DCI-P3 color space is 98 %.
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 10000000 : 1 of dynamic contrast ratio for the monitor Omen 27i 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 Omen 27i without stand/feet: 36.7 cm x 61.3 cm x 6.6 cm (HxWxD)
If you want to place the monitor described here on the desk without a wall mount, you should allow for 39.2 x 61.3 x 25.7 cm (HxWxD) of space. The device weighs 7.75 kg with the stand in place. A height-adjustable stand ensures an improved ergonomic posture during use. The monitor can be moved to a maximum height of 13 cm. This value is always measured from the bottom edge of the screen. The monitor has built-in RGB lighting. On some monitors, RGB lights are often used as "backlighting" or "ambient lighting". These may be placed on the back of the monitor and illuminate the screen outline or the space behind the monitor. Some monitors, on the other hand, use RGB lighting on the front or bottom of the screen to create visual effects that can be synchronized with the content being displayed.
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. The monitor Omen 27i can be tilted. The angle of inclination to the rear is 20. The monitor can be tilted forward by 5 degree.

Features
- AMD FreeSync: By dynamically synchronizing the refresh rate of the Omen 27i with the frame rate, AMD FreeSync minimizes judder and ensures smooth and enjoyable gameplay.
- Nvidia G-SYNC
- The display/monitor supports Frame Rate Compensation.
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 LM270WQA-SSA1.
WiFi / Bluetooth
Power consumption
On average, the monitor consumes approximately 50 w. The maximum power consumption (peak) specified for this monitor is 75 w. In standby mode, the device consumes approximately 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
During operation, the ambient temperature must not exceed 35 °C , to ensure full functionality. 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.
Packaging
The monitor is packaged in a cardboard box measuring 46 x 73 x 25 cm (height x width x depth). The box together with the monitor weighs about 10.57 kg.
