LG 23ET83V-W monitor review and testing

According to the fact that last year many manufacturers of computer components and game developers actively promote 4K Ultra HD format, Full HD standard is still the most popular among the majority of users. It’s why it is not a surprise that the major part of monitor market includes devices with screen sizes 23"- 24" and resolutions up to 1920 x 1080. However, it is not correct to say that in this area there is some kind of deadlock, because in spite of matrix size there are some other parameters to be improved. In addition, to maintain the competitiveness of own products manufacturers should to keep up to date and constantly introduce new and relevant technologies. Touch screen monitor is a good example to above mentioned. Many large companies in particular LG has already presented models that support processing of multiple simultaneous touches to the display. This review will contain the information of such monitor LG 23ET83V-W.

Packaging and delivery set

LG 23ET83V-W

LG 23ET83V-W monitor is delivered in a carton box that protects device against impact and mechanical damages. For comfort transportation on the top there is a plastic carrying handle.

On a front side there is a model image as well as description of LG TOUCH 10 function. In addition you can find a number of logos that describe monitor facilities and technologies:

  • IPS panel;
  • Windows 8 Compatible;
  • 10 Point Finger Touch;
  • LED;
  • Super Energy Saving;
  • Full HD (1920 x 1080).

The most important and attractive feature of this monitor is its 23 inch diagonal.

Set of delivery includes the following components:

  • Network adapter (AC: 100 - 240 V/ 50 - 60 Hz / 1,1 А; DC: 19V / 1,3 А);
  • Power cable;
  • 2xD-Sub -cable;
  • USB-cable;
  • Users manual;
  • Product documentation and software CD.

It is interesting to note that there are two D-Sub cables and there is no cable to connect the monitor via a digital video interface. If you decide to buy LG 23ET83V-W, you should pay attention to this point.

Design and technical specification

LG 23ET83V-W

LG 23ET83V-W monitor has quite common features to 23’’ options. Plastic case with wide frames around screen. But due to the usage of touch panel their dimensions are not very noticeable. Visually it may even seem that display diagonal exceeds 23 inches. Regarding design the manufacturer decided to make an experiment. Instead of the traditional black or white color a combination of these colors was used. The front of the monitor is black while the back panel is white and glossy. This design looks quite interesting.

LG 23ET83V-W

PSU is outside of monitor case, but LG 23ET83V-W model is relatively heavy (6.4 kg). Manufacturer refused to install VESA wall mounting system. Thanks to the touch panel, the monitor expands the scope of its applications. For example it can be used as an electronic blackboard, interactive board or in other cases where it is required not only image output but also data input in real time.

Stand has high rigidity, but it cannot boast by great functionality. Angle of inclination is -5° +25°.

Traditional control buttons are replaced by the sensor elements; this adds elegance to monitor appearance. Under the button «Power» you can detect a slight relief.

Integrated LED during operation has red color, and during idle it flickers. In both cases the brightness is mild and will not distract the user for example at watching a movie in the dark.

LG 23ET83V-W

Model LG 23ET83V-W has no multimedia components (speakers, microphone, WEB- camera) so we would like to move on to the interface panel. The following connectors are grouped on the back side of a monitor: network adapter, two HDMI ports, headphone audio output, D-Sub and USB. USB is used for the proper operation of the touch panel. Other devices cannot be connected to it. Also we would like to pay your attention to the presence of two HDMI digital video interfaces. Using these interfaces monitor can receive a signal from two different sources, such as computer and video player. Switching between sources is possible by «INPUT» button on the touch panel.

Using quick keys it is possible to lock the menu access, activate Super Energy Saving function (low power consumption) and select preinstalled profiles.

When you select on screen menu you will obtain an access to the basic parameters brightness and contrast.

For more accurate setup you should use inlay "Next". Here you can set image accuracy, gamma, color temperature and the level of each of the six basic colors.

The users are offered a choice of ten profiles divided into two groups: AV and PC. AV modes are available to connect a monitor via a video interface HDMI.

Testing

Profile main parameters

Since the names of some profiles coincide, for a better understanding we will use the prefix «PC» and «AV».

Main characteristics of preinstalled modes are given in the following table:

Before the analysis of the results we would like to make a small note: after testing we identified that the characteristics of profiles "AV_User" and "PC_User" coincide, so we decided to combine them under the name «AV/PC_User".

According to the passport data, the maximum brightness of the monitor is 250 cd/m2. However, no one of the profiles has this value. Moreover, all profiles with the prefix «AV» (except “AV/PC_User”) had a brightness value 110 - 125 cd/m2. If you spend much time in front the monitor, it would be perfect to use these profiles for work to reduce the load on eyes. But for those who prefer bright images, the value 176.9 cd/m2 is not enough, especially when the monitor is placed in a well lighted room. We did not found official data about the value of static contrast coefficient for this model. That is why in conclusions we will consider the tested results. To tell the truth these results are not impressive.

Value of the static contrast varied within 181:1-236:1, whereas competitive model’s value was 800:1 or higher. So instead of rich image you can get its duller version. Monitor's power consumption in all profiles is almost the same 24 - 25 W. Certain value has "AV_Movie" mode with its power consumption about 19 W. It is pretty interesting that while the activation of Super Energy Saving function this value still remains at level 20W, although it was supposed to be reduced at least twice (according to the manufacturer information even up to 6 W).

In all cases there’s approximately the same situation – green and red reference points are shift from sample tops of triangle with sRGB standard. Due to this fact excess of color range will be in light-green and yellow-orange zones. The worst result CIE-diagram has in modes “AV-Movie” and “PC-Movie” as their graphs do not cover some hues in  turquoise and pink colors. In quantitative indices it is expressed as follows:
