LG 24MP76HM-S monitor review and testing

It's no secret that LG is one of the world's leading manufacturers of monitors. But to maintain this status it needs to constantly update the range and improve the performance of the devices. However, in the segment of 24-inch monitors today is one of the most saturated. So sometimes you have to look unconventional moves and even experiment to persuade the buyer to one’s side. LG decided to go the other way. Instead of reinventing the wheel its engineers took a well-proven matrix IPS and just wrapped it in a nice wrapper. The result is a new family called LG Cinema Screen. Flagship model we will consider in this review. We are talking about the monitor LG 24MP76HM-S.

Packaging and content

LG 24MP76HM-S

Monitor LG 24MP76HM-S is shipped in quite big cardboard box which provides protection against impacts and possible mechanical damages during transportation. In addition to the image of the device, on the sides of the package also are its main features. First of all its screen size (24’’r 60 cm) and the type of matrix (IPS). Other features are presented in a series of logos with short inscriptions:

  • Cinema Screen – a very thin frame that miniaturizes the monitor is used around the screen;
  • Stereo Speaker – presence of two integrated speakers;
  • Reader Mode - among preset profiles there are modes with specially selected settings to reduce eye strain during prolonged reading text from the screen;
  • 2 х HDMI - presence of two digital video interfaces HDMI.

  • Cable clamp;
  • CD with documentation and software;
  • User’s manual

Design and usage properties

LG 24MP76HM-S

Monitor LG 24MP76HM-S has a fine appearance and in terms of design stands out among the competitors. Instead of ordinary dark matte paint manufacturer had used a combination of silver and black colors with gloss hue. The width of frames around the screen is reduced by half (from 10-11 to 5.6 mm), and it is covered with a protective glass that visually increases the size of the monitor. It seems that its diagonal is not 23.8’’ but much more. Such “frameless” case perfectly matches with transparent leg and stand painted in a light color. At night time (when the screen is on) it gives the impression that the monitor is kite in the air. But also in the afternoon the model LG 24MP76HM-S attracts a lot of attention. Taking into account that the display as a computer system unit very often are in sight its appearance and design is quite an important factor, and in some cases even decisive.

LG 24MP76HM-S

The power supply unit is outside the monitor so it has a relatively small case thickness. In the center of the rear panel there are mounting holes VESA 75 mm. Thus, LG 24MP76HM-S can be mounted on the table and the wall. We could not find information about leg material; however, experience has shown that there is no reason to doubt in its strength.

LG 24MP76HM-S

The producer primarily focused on structural reliability sacrificing its functionality. The leg has only one articulated joint and the screen angle can vary within -5° ... +20°. More regulations are not provided. At the end of the transparent plate a special plastic overlay with a special cavity for cable holder can be mounted.

Stand is a large metal plate, covered at the top with silver matt plastic. On its perimeter there are glued rubber inserts designed to improve the stability of the monitor on the table, as well as protect it from scratches.

Video connectors are represented by one analog D-Sub port and two digital HDMI. All graphics interfaces support a resolution of 1920 x 1080 at frequency sweep 60 Hz. Also of note two audio outputs: one of them (AUDIO IN PC) is designed to connect the audio cable to the sound card, the other (H/P) is used to connect headphones.

In addition, the sound can also be played via two built-in speakers with a total capacity of 10 W. They are playing noticeably louder than other monitors with speakers, but their sound quality is not very high. For comfort music playing such speakers won’t be a perfect option but for sound playing from videos in the Internet implementation of video calls or video conferencing they are suitable. Therefore, their main purpose is to save space on the desktop.

Buttons to control and navigate the monitor in the menu are located on the end side of the case and have explanatory inscriptions. In the corner you can find a small display operation indicator. In the active state it is white and during idle mode it flickers. In both cases the brightness is moderate and LED placement does not distract the attention in the dark times.

Display menu and operational demonstration of proprietary technologies

On-screen menu is divided into two parts. Access to the first is carried out by pressing the button “MENU”. This will open a window where you have options for brightness, response time and volume of the integrated speakers. To see more options, go to the “Next”.

As a result you will have a new window with several tabs where basic and advanced settings for manual adjustment of the monitor settings are grouped. They are: contrast, sharpness, black level, balance of primary colors, etc.

To access the second part of the On-screen menu you should use the button “FUNC”. Here you can manage the integrated technologies, as well as selection of the preset profiles. Traditionally, they are divided into two groups under the names “PC” and “AV”.

In addition, the model LG 24MP76HM-S has another group that contains two profiles: “Reading Mode 1” and “Reading Mode 2” (to access it press the button “READER”). All of them we consider in more detail during testing. Now let's analyze the operation of technology LG Super + Resolution which increases the sharpness of the image.

It works quite well and can be useful in different cases, such as when reading text from scanned pages or photos. However, in games or 3D-graphics applications this feature should be disabled.
Testing
As we’ve reported above, the monitor has three preset profiles group. The names of some modes coincide, so for better understanding will be used the prefix “PC” and “AV”. In addition, the characteristics of profiles “AV_User” and “PC_User” coincide, so we decided to combine them under the name “PC/AV_User”.

Study of characteristics of “PC” profiles group

 
First of all we are going to examine the group which includes modes intended for use in daily work with the computer (OS interface, multiple applications, games and movies). It is called “PC” profile and has 5 profiles: “PC_Text”, “PC_Photo”, “PC_Movie”, “PC_Games”, “PC/AV_User”.

CIE-diagram of “PC_Games” profile

CIE-diagram of other profiles from the group “PC”

 From the viewpoint of corresponding index of color space to standard sRGB the best mode is "PC_Games" with a fairly high value of 95.2%. The results of other profiles can be called medium (87.0% - 89.1%). Their CIE-shift diagrams clearly reflect green and red reference points relative to the reference triangle vertices sRGB. Due to this fact the excess in the color range is light green, yellow-orange and red zones, and the lack - in dark green, turquoise and pink. In "PC_Games" mode we can say about saturated color from light green to orange zones.

However, an excellent level of color gamut is not the key to good performance in the other experiments. Vice versa when the mode "PC_Games" is activated the worst results of color accuracy were recorded. Other profiles have coped with this problem much better. Especially we want to mention the modes "PC_Text» and «PC/AV_User", where the average deviation dE*94 (ΔE) from the reference is equal to 0.62 and the maximum is 1.94-1.99. Recommended values are ≤ ≤1 and ≤3respectively.

The level of the average range has the same value as in the previous test. The leaders are profiles "PC_Text» and «PC/AV_User" with values of 2.11 and 2.12 respectively, however the benchmark 2.2 is not achieved. As a result, the picture on the screen will be little less contrast than it should be, and may have lost some of the details in the shadows of light objects.

By the way, weI would like to say about the absolute values of the static contrast ratio. Only modes "PC_Text" and «PC/AV_User" can provide acceptable values for this parameter (686:1 and 673:1, respectively). When you activate the remaining profiles of the group «PC», the static contrast ratio falls to 220:1 - 260:1. That’s not good result since instead of juicy and rich images on the screen you’ll get it duller version.

Graph of RGB  level of “PC_Text”, “PC/AV_User” profile

Graphics of RGB levels only confirm our view that the best in the group «PC» modes are "PC_Text» and «PC/AV_User." Deviation from the norm of 100% on the entire brightness range does not exceed ± 10% which is a good indicator. There is no sense to test the other profiles with the prefix «PC» as they get worse value and will not affect the result.

Study the characteristics of group profiles “AV”

The next group of profiles is called «AV» and also includes five sections: «PC/AV_USer" "AV_Bright1" "AV_Bright2" "AV_Standara" and "AV_Movie". Mode «PC/AV_User" was studied in detail in the previous paragraph.
