Today we will look at the monitor 27MP77HM-P from LG from the year 2015. 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
Let's start with the size of the display. It is 27 inches ( 68.4 cm on the diagonal) large and should thus offer enough space for all contents according to LG. 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 LG. 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, 88.7 % 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 AH 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 LG 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. LG promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the 27MP77HM-P 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 average response time of the monitor is about 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 %. 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 LG 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 27MP77HM-P 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
LG Specifies the following dimensions for the monitor 27MP77HM-P without stand/feet: 36.9 cm x 61.4 cm x 5.2 cm (HxWxD)
If you want to place the monitor described here on the desk without a wall mount, you should allow for 46.9 x 61.4 x 18.2 cm (HxWxD) of space. The device weighs in total (i.e. also measured with the stand) 4.8 kg. According to LG , you can expect a weight of about 4.3 kg without the stand. Speaking of weight without a stand and thus wall or table mounts. The monitor supports a Vesa mounting.
Rotate, tilt and swivel
The monitor from LG cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. The tilt of the monitor 27MP77HM-P can be individually adjusted to optimize the viewing angle and increase comfort during use. The angle of inclination to the rear is 20. The monitor can be tilted forward by 3 degree.
Ports
The monitor can be connected via 1 VGA ports.
camera
This monitor does not have a camera.
Loudspeaker
The monitor from LG 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 5 w power.
Features
- Flicker Free: LG 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
- 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 LG 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 LM270WF7-SSA1.
WiFi / Bluetooth
Power consumption
On average, the monitor consumes approximately 20 w. The maximum power consumption (peak) specified for this monitor is 29 w. In standby mode, the device consumes approximately 0.3 w. When switched off, on the other hand, the monitor consumes only 0.3 w. In ECO mode, the monitor consumes 15 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. There are 1.7 amps specified. The power grid has to supply a frequency of 50 hz to 60 hz.
Environment
During operation, the ambient temperature must not exceed 40 °C , to ensure full functionality. Below a temperature of 0 °C , the monitor from LG should again not be used. The humidity must not exceed 80 percent. At least, however, 10 percent humidity. The monitor may be stored at a maximum humidity of 85 percent. The minimum humidity during storage should not fall below 5 percent. The maximum storage temperature should be according to LG 60 °C. Minimal were given by LG -20 °C.
