What is dfc in lg monitor settings. New from LG Technology: The world's highest monitor contrast ratio has been achieved. ⇡ Testing methodology

At the end of May, LG Electronics presented on the Russian market a 23-inch W2363D gaming monitor with a resolution of 1920Ѕ1080 (Full HD) and support for NVIDIA 3D Vision technology.

Design

The LG W2363D monitor features an elegant design. With a thickness of 7.33 cm, the monitor is attached to a stand with a wide oval base, which allows you to tilt the monitor from -5 ° to 15 °. Note that the power supply in this monitor is external, and the weight of the device is only 5.2 kg.

The dimensions of the monitor without a stand are 55.55x40.95x7.33 cm, with a stand - 55.55x41.92x20.6 cm.

The surface of the screen of the monitor LG W2363D has a matte anti-reflective coating, and the plastic frame framing it is glossy black.

In the lower right corner of the monitor, there is a touch-sensitive power button, a power indicator and a six-button touch panel for monitor settings.

Specifications

The monitor LG W2363D uses a widescreen (aspect ratio 16: 9) TN-matrix with a diagonal size of 23 inches (58.4 cm).

Recall that TN-matrices are now used in most LCD monitors. These are the cheapest matrices, which are distinguished by a high pixel switching speed (low pixel response time) and, unfortunately, not very good color reproduction and small viewing angles. Another drawback of TN-matrices is that the black color in them is not black, that is, it is not possible to turn off the pixels so that they do not transmit light at all. It is precisely with this that the fact that TN matrices do not have very high level static contrast, measured as the ratio of brightness against a white background to brightness (at the same settings) against a black background. True, partially this problem solved in the monitor LG W2363D due to the use of dynamic contrast enhancement technology, which we will discuss below.

The maximum resolution supported by the monitor is 1920x1080 pixels with a pixel pitch of 0.266 mm. The resolution of this monitor allows it to be classified as Full-HD.

There are three connectors for connecting the W2363D monitor to a computer: one DVI-D and two HDMI, and there is a button on the touch control panel that allows you to select a signal source. Thus, this monitor can be connected to three computers at the same time and switched between them using the source selection key.

In addition to connectors for connecting the monitor to a computer, it provides audio connectors (input / output), one of which (input) is used to connect to the audio output of the PC, and the second is used to connect headphones.

According to the declared technical characteristics, the maximum brightness of the TN-matrix used in the monitor is 400 cd / m2, and the contrast level is 70,000: 1 DFC.

Recall that DFC (Digital Fine Contrast) is a technology developed by LG to enhance contrast and improve the subjective perception of images on LCD monitors and TVs. In fact, it comes about option dynamic contrast which has little to do with static contrast. DFC technology is divided into three components: ARC, DCE and DCM.

ACR (Auto Contents Recognition) is an automatic content recognition technology. The meaning of the technology lies in the fact that the type of viewed image is determined and, depending on the type of image, the desired levels of brightness, contrast and color saturation are set.

DCE (Digital Contrast Enhancer) - digital contrast enhancement by reducing the luminescence of black areas of the image.

DCM (Digital Contrast Mapper) is a contrast distribution technology that provides an optimal contrast level.

Well, now let's try to explain everything the same, but on the fingers, without using obscure terms.

Generally, the static contrast of an LCD panel is defined as the ratio between the brightness of white and black. The difference between the concepts of static and dynamic contrast is that in the first case, the brightness of the backlight during measurements should remain unchanged. Therefore, the static contrast ratio is a characteristic of the LCD panel. In the case of dynamic contrast, the brightness of white and black is measured separately, that is, at different brightness levels of the backlight.

In order to increase the dynamic contrast ratio, it is necessary to reduce the luminance of the black color, which is easily achieved by reducing the brightness of the backlight to the minimum level. Therefore, dynamic contrast will always be much higher than static contrast.

Monitors with DFC technology track the distribution of image brightness across the display field and adjust the backlight mode accordingly. If there is a white object (R = G = B = 255) on the screen, then the contrast in this frame will not differ from the static indicator and DFC will not be able to improve it in any way. However, if there are no such objects, then it becomes possible to reduce the radiation intensity of the backlight lamps by performing an appropriate recalculation of the image in the direction of increasing brightness. In this case, the level of black luminosity will really decrease, which will have a positive effect on the perception of the picture by the viewer. Actually, this is the essence of DFC. Thus, the dynamic contrast ratio is rather abstract, and in practice it can only be achieved by alternately displaying black and white fields. This technology is important when watching movies or playing games where dark scenes are often encountered; however, it makes no sense for traditional PC work, and static contrast has a much more serious impact on image quality.

As for the other characteristics of the W2363D monitor, they are as follows.

The viewing angles of the monitor are 170 ° horizontally and 160 ° vertically. Note that in this case we are talking about viewing angles measured by the classical method of calculating viewing angles by reducing the contrast level. That is, the limiting viewing angle corresponds to the direction for which the contrast level is reduced by a factor of 10 compared to the contrast level measured along the normal to the screen surface.

The LG W2363D has a claimed 3ms pixel response time (GTG). Recall that the pixel response time can mean both the total switching time from black to white (on time) and vice versa (off time) - in this case, they talk about the Black-To-White (BTW) technique, and the average switching time between with different semitones (grayscale) is the Gray-to-Gray (GTG) technique.

Note that the monitor settings provide the ability to enable or disable the RTC (Response Time Control) mode, which allows you to reduce the pixel response time to a minimum.

And the last thing to pay attention to when talking about technical characteristics ah monitor LG W2363D, is its frame rate. Since we are talking about a monitor with support for NVIDIA 3D Vision technology, the vertical frequency is 120 Hz, while for a conventional LCD monitor it is 60 or 75 Hz.

However, you need to keep in mind that when the monitor is connected via HDMI at the monitor's native resolution of 1920x1080, the maximum frame rate can be only 60 Hz. You can set the vertical frequency of 120 Hz at a resolution of 1920x1080 only when the monitor is connected via the DVI-D interface. And you need to use a Double Link cable, since the traditional DVI-D Single Link cable does not support such a high frame rate at this resolution. Note that the DVI-D Double Link cable is included with the monitor, but the HDMI cable is not.

Naturally, the monitor comes with active 3D glasses from NVIDIA with an infrared transmitter. Recall that the only requirement for monitors to support NVIDIA 3D Vision technology is a vertical refresh rate of 120 Hz. Everything else is done at the level of the video card driver and special NVIDIA glasses. It is natural that this technology will only work with NVIDIA graphics cards that support it. Therefore, when purchasing a monitor with support for NVIDIA 3D Vision technology, you should also consider purchasing an appropriate NVIDIA graphics card in advance.

In order to understand what, in fact, is the difference between conventional monitors and monitors with support for NVIDIA 3D Vision technology, let's remember how the stereo image is formed.

The idea of ​​forming a stereoscopic image is not new and consists in generating two separate images for each eye, the viewpoints of which are somewhat displaced relative to each other. As a result, each eye sees its own picture, and our brain, thanks to this cunning deception, forms the illusion of a three-dimensional image.

There are several ways to form a stereoscopic image. The simplest method is based on the color separation method, which is often used in 3D cinemas. For this, glasses are used with light filters of different colors (usually blue and red) for each eye. As a result, it is possible to form different pictures for each eye and obtain a stereoscopic image.

Another way of forming a stereoscopic image is polarizing image separation. In this case, glasses with polarizing filters of different directions are used, as a result of which a picture can be formed for each eye. This method of forming a stereo image is also used in 3D cinemas.

Another way is the active shutter glasses system. Actually, this is the NVIDIA 3D Vision technology. In this case, glasses with active LCD shutters are used. in the following way: when one shutter is open, the other is closed, and vice versa. Moreover, the response frequency of the LCD shutters is 60 Hz. The monitor, synchronized with the glasses, reproduces the image at a frequency of 120 Hz. That is, each frame is, as it were, divided into two subframes for the left and right eyes. All even frames fall into one eye, and all odd frames fall into the other. Moreover, for each eye, the frame rate will be 60 Hz, but for a monitor, the frame reproduction rate should be 120 Hz.

Naturally, with this method of forming a stereo image, the operation of the LCD shutters must be strictly synchronized with the change of frames on the monitor screen. Actually, for such synchronization, the IR transmitter is intended, which is connected to a computer and interacts with the glasses wirelessly.

Customization options

As we have already noted, a six-button is designed to control the monitor. Touchpad located in the lower right corner of the device.

In addition to the traditional brightness and contrast adjustment for all monitors, the LG W2363D has other specific settings. Brightness and contrast can be adjusted in very small steps, allowing accurate monitor calibration. The possibilities for setting up the monitor depend on what interface it is connected to. For example, when connected via any interface, you can change the brightness, contrast and sharpness, and for the HDMI interface there are additional settings allowing you to change the black level, hue and saturation.

You can also use the auto brightness mode to adjust the brightness. When activated, the ambient light sensor is activated and automatic setting the optimal level of monitor brightness depending on the ambient light in the room.

The color adjustment system allows you to choose one of three preset modes with different color temperatures: sRGB, 6500 and 9300 K. In addition, you can independently set color temperature by adjusting the level of each channel (R, G, B) separately for the white point.

In addition to the listed options for adjusting the LG W2363D monitor, which are needed mainly when calibrating it, there are many other custom settings.

In particular, since this monitor is positioned as a gaming monitor, a special TRU-LIGHT Button is provided in the control panel, which allows you to select one of the preset monitor setting modes: "Game", "Cinema" and "Music".

Testing

After getting to know the LG W2363D monitor, we just have to announce the results of its testing.

During testing, the monitor was connected to a computer via a DVI-D digital interface, and to measure its technical characteristics, a software and hardware complex was used, including a GretagMacbeth Eye-One Pro spectrophotometer, ProfileMaker Pro 5.0.5 software, basiCColor Display 4.1.9 software, digital oscilloscope BORDO 211A and photosensor.

During testing, the following monitor characteristics were measured:

• maximum and minimum brightness;
• static contrast;
• color accuracy;
• color gamut of the monitor;
• pixel response time.

Maximum and minimum brightness

Before proceeding to review the test results, we emphasize that the characteristics declared for the LCD matrix (monitor) itself and the values ​​that can be measured are far from the same thing. Thus, the maximum and minimum brightness can be measured in different ways (for example, at different color temperatures and for different monitor profiles), and therefore, different values ​​can be obtained. Naturally, the indicators that are important for the user are those that he / she will receive with the working (that is, comfortable for work) monitor settings.

A GretagMacbeth Eye-One Pro spectrophotometer was used in conjunction with the basiCColor Display 4.1.9 software to measure the maximum and minimum brightness. The values ​​of the maximum and minimum brightness were recorded in center point screen.

The monitor was initially calibrated and profiled with the following settings in basiCColor Display 4.1.9:

• calibration method - Software (the monitor does not support the function of editing the LUT-table (hardware calibration), therefore, it is only possible to edit the LUT-table of the video card (software calibration);
• Calibration Setup - Office:
  • white point - D65,
  • tonal range - 2.2,
  • glow - white maximum (120 cd / m2), black minimum;
• profile setting - LUT based:
  • profile type - 16-bit LUT,
  • chromatic adaptation - CAT02.

After calibrating and creating a profile using the basiCColor Display 4.1.9 software, the maximum and minimum brightness values ​​were measured over the white field at the center point of the screen.

When measuring the maximum brightness in the monitor settings, the contrast level and brightness level were set to 100%, and when measuring the minimum brightness, they were set to 0%.

According to the measurements, the maximum brightness range of the LG W2363D monitor at the center point of the screen is from 14 to 350 cd / m2.

Color accuracy

It should be noted that the color accuracy depends very much on the set brightness level, and on the monitor calibration, and on the created profile. Typically, several calibration procedures are performed and several monitor profiles are created, and then the profile that most closely matches the color reproduction is selected.

When determining color accuracy, the monitor was pre-calibrated and profiled in the same way as when determining maximum and minimum brightness. Note that the brightness level was set equal to 120 cd / m2. Then, using the basiCColor Display 4.1.9 program (already without calibration and profiling), the color accuracy was assessed by comparing the reference color template with the results of its measurement. According to the results of the comparison, the value of the color difference DE 94 averaged over all color fields was determined. According to the measurements, it was 0.7 (Fig. 1), which is a very good result for a monitor that, in principle, is not intended for professional work with color. ... In general, when the D E 94 value is less than one, we can talk about very high color accuracy. In any case, it is simply impossible to notice the difference in color by eye when D E 94 is less than one. Well, the value of D E 94 averaged over all color fields, equal to 0.64, means that under normal conditions it is unrealistic to determine the deviation for most of the color fields by eye.

Monitor color gamut

The color gamut of the monitor was determined using software package ProfileMaker Pro 5.0.5 from a saved profile from monitor calibration and profiling.

As it turned out (Fig. 2-5), the color gamut of the LG W2363D monitor is very close to the color gamut of a standard monitor with sRGB profile (although slightly different from it).

Pixel response time

A photosensor and a BORDO 211A digital oscilloscope were used to measure the pixel response time.

When measuring with special utility turned on or off horizontal line one pixel wide that could be grayscale. By means of a photosensor and an oscilloscope, the time of the change in the pixel brightness was recorded.

The pixel response time measurement method is similar to the Gray-to-Gray (GTG) measurement method, but it does not completely repeat it, therefore the measurement results cannot be compared with the technical data provided in the documentation.

The pixel response time was measured on a monitor calibrated according to the above method. The level of brightness and contrast was set equal to the maximum value.

During testing, the transition time was measured between the following states of halftones (in coordinates R-G-B) pixels: 0-0-0, 50-50-50, 100-100-100, 150-150-150, 200-200-200, 255-255-255.

The transition time was understood as the time during which a pixel changes its brightness from 0 to 90% or from 100 to 10%.

After measuring all possible transitions between different halftones, the average value of the pixel response time was calculated. To calculate the average value, the geometric mean transition time between all semitones was calculated. The value calculated in this way is the pixel response time according to our measurement method.

It should be noted that measuring the pixel response time on modern LCD monitors can be challenging due to the pulse width modulation of the backlights, which flicker at a high frequency (invisible to the eye). Due to the pulse-width modulation of the backlight lamps, the brightness of the monitor is adjusted, that is, by changing the flickering duty of the backlight lamps, it changes average level brightness (the duty cycle is the ratio of the time during which the lamp is on, to the total time the lamp is in the on and off state).

In order for the measurement of the pixel response time to be possible, it is necessary to get rid of the flickering of the backlight lamps. That is why, when measuring the pixel response time, we set the maximum brightness of the monitor, at which the lamps do not flicker.

The results of measuring the transition time between different states of the pixel are shown in the table. The average pixel response time, calculated according to the method we described, was 4.2 ms. If we talk about the switching time of a pixel from black to white, then it is 4 ms, and the shutdown time is 1 ms.

conclusions

Summing up the testing of the LG W2363D, we can say that this is a stylish, functional monitor with good characteristics. It can be used with equal success for work in traditional mode and for games in 3D mode.

Of course, main feature This monitor is compatible with NVIDIA 3D Vision technology.

It should be noted that today there are about 400 games with support for NVIDIA 3D Vision technology. There is simply no other content other than games in the 3D Vision format. That is, there are no films that can be viewed in 3D on a monitor with NVIDIA 3D Vision technology. Whether such films will ever appear is a big question, since it is hardly possible to say unequivocally that the future belongs to NVIDIA 3D Vision technology. For example, 3D monitors and TVs have already appeared that do not require the use of any glasses at all, and this technology may turn out to be much more promising.

However, time will tell which technology will become generally accepted. So far, only one thing is indisputable: the future belongs to 3D technologies and in currently we are at the initial stage of their development. Moreover, NVIDIA 3D Vision technology is just one of them.

Note that this technology has both advantages and disadvantages. The advantages include high quality 3D images, but the disadvantages are a whole list. Firstly, this technology requires the use of special glasses, and very uncomfortable ones. Secondly, you won't sit for a long time with these glasses - your eyes start to hurt. Thirdly, there is only a limited list of games that support this technology. Fourthly, this technology is tied to NVIDIA graphics cards and won't work with ATI video cards... In addition, when NVIDIA 3D Vision technology is used, the performance of the video subsystem is significantly (almost halved), that is, in games, an indicator such as FPS (frames per second) drops, and many games will slow down. Actually, the last circumstance requires that when using NVIDIA 3D Vision technology, a sufficiently powerful video card is used, which, naturally, increases the cost of the entire solution as a whole.

The segment of mass 19-inch monitors today cannot be called super-profitable, and the competition in it is very high. There is practically no technological progress here, unless, of course, the constant search for ways to reduce production costs is considered as such. This is necessary in order to stay profitable in the face of constant falling prices. Of course, not everyone follows this path, but agreeing with some of the marketing arguments can be tricky too.

Excellent appearance and construction; good panel contrast

Congenital deficiencies of TN-matrices and deviations in color reproduction

Monitors are designed primarily for work, will easily fit into any interior

LG has been betting on the special design of its own devices for a long time, and in modern conditions such a policy brings very good results. So it comes as no surprise that the two new 19-inch Flatron LCD monitors look quite attractive as well. After all, coming to a store, customers often choose a display based on its cost and appearance, and already in the second place they are interested in characteristics.

Design, construction and characteristics

Let's say right away: there are no complaints about the new products on these points. The glossy black lacquer and rounded contours of the case make the devices very elegant, making them sure to fit into almost any interior. In addition, the design of the stand allows you to adjust the height of the panel over a wide range, which is very convenient.

In terms of characteristics, the main difference between the models is the aspect ratio: the Flatron L1972H belongs to the traditional "nine", and the Flatron L197WH - to the widescreen displays. Other parameters for both devices are almost the same, and are not in any way outstanding by modern standards - TN-type matrices, response time 2 ms (with acceleration pulse compensation). Only one parameter is of increased interest - LG indicates the contrast of its new monitors at 5000: 1 (DFC). We will now take a closer look at how such high rates were obtained and what the mysterious abbreviation in brackets means.

Dynamic contrast

LG Flatron L1972H and measurement results. The maps of unevenness of the white (a) and black fields (b) are significantly enhanced

This phrase is already well known to users interested in the subject of display devices, since, for example, in the segment of consumer electronics, many manufacturers do not even give other contrast values. While the usage patterns of computer monitors and LCD TVs tend to differ significantly, LG has decided to take the same approach for the Flatron line of displays. Well, since this is the case, let's remember what is called dynamic contrast and what is its main difference from static.

In general, panel contrast is defined as the ratio of the luminance of the white and black fills. The difference between the concepts of static and dynamic contrast is that in the first case, the brightness of the backlight during measurements should remain unchanged, that is, they are carried out within the same image on the screen. Therefore, the static contrast ratio is a characteristic of the LCD panel and, by and large, does not depend on the operation of the control electronics of the monitor. In the second, there is no such limitation - the brightness of the white and black fills is measured separately. Therefore, in order to increase the dynamic contrast ratio, it is only necessary to reduce the luminance of the black field, which is easy to achieve by reducing the brightness of the backlight to the minimum level. Consequently, the dynamic contrast figure will always be much higher than the static one.

Systems like LG's DFC (Digital Fine Contrast) monitor the distribution of image brightness across the display field and adjust the backlight mode accordingly. If there is a white object (R = G = B = 255) on the screen, then the contrast in this frame will not differ from the static indicator, and DFC will not be able to improve it in any way. However, if there are no such objects, then it becomes possible to reduce the radiation intensity of the backlight lamps by performing an appropriate recalculation of the image in the direction of increasing brightness. In this case, the level of black luminosity will really decrease, which will have a positive effect on the perception of the picture by the viewer.

Thus, the dynamic contrast ratio is rather abstract, and in practice it can only be achieved by alternately displaying black and white fields. In addition, this improvement is important in the case of watching movies or games, where dark scenes are often encountered; however, with traditional types of work on a PC, there is no point in this, and much more important influence the image quality is affected by the static contrast ratio.

Features and image quality

LG Flatron L197WH and measurement results. The maps of unevenness of the white (a) and black fields (b) are significantly enhanced

TN-type matrices traditionally suffer from a number of "innate" shortcomings, which we have already written about many times - this is, first of all, a strong dependence of the color and contrast of the image on the angle at which the user looks at the screen. Unfortunately, this is also supplemented by a poor-quality calibration of devices in the factory for color temperature, which leads to the fact that the midtones have a pronounced shift in "cold" or "warm" shades compared to white. Manufacturers simply cannot pay more attention to this process, since it entails certain costs. And given that we are talking about mass devices, there is also little hope for the use of a hardware calibrator by the user in this case.

We have to admit that the new Flatrons are just a confirmation of this trend. The deviation of the color temperature from the reference in all color modes for both models is noticeable with the naked eye, while for the Flatron L1972H there is a shift in green tones (which is why our calibrator even refused to register the color temperature of the panel on gray dots), and for the Flatron L197WH - in blue, which makes the picture unnecessarily cold. After profiling, as expected, everything falls into place, and the error value ∆E does not exceed generally accepted norms.

The brightness adjustment range for both models is optimal, but for a more comfortable work, we recommend changing the default values ​​by 50% - for both brightness and contrast, which will avoid increased eye fatigue and oversaturation of light areas of the image. To correct deviations in the color rendition of these models in the User Color chromaticity mode, you should use the ICM profiles we created during testing - they, like more detailed test results, are available on the website ko-online.com.ua. However, it should be borne in mind that the use by the manufacturer of another batch of matrices in these devices can radically change the situation, and these measures will become irrelevant.

The dither subsystem works flawlessly, no flaws are noticeable on the gradients. As for the dynamics, the implementation of the acceleration pulse technology is still not ideal here, as evidenced by the white border behind a black object moving against a light background.

The uniformity of the illumination of the devices is significantly different. While this is all right for the Flatron L1972H, the widescreen L197WH exhibits significant deviations in blackfield luminance, probably caused by the use of extended length CCF lamps.

Conclusion

The new Flatron models will undoubtedly attract the attention of buyers by combining excellent design, good characteristics and affordable price... At the same time, their disadvantages include significant deviations in color reproduction for all provided color modes, which can only be corrected by performing hardware profiling of devices.

As for the dynamic contrast increased to 5000: 1, in our opinion, this indicator is not a priority for a computer monitor. On the other hand, static panel contrast measurements also show an improvement of 800: 1 (compared to 600-700: 1 in previous models), which is considered an excellent result for TN panels.

Digital Fine Contrast (DFC) technology enables new and existing monitors to deliver 5000: 1 dynamic contrast for incredibly vibrant colors

LG Electronics (LG), one of the leaders in the global digital display market, announces that the company's monitors, which will be produced from September 1, 2007, will provide a contrast ratio of 5000: 1 (which, thanks to DFC technology, is the highest in industry today).

Designed for clearer, clearer and more vibrant images, Digital Fine Contrast technology will be found in all LG monitors except the M8W, L18, L196WS and Emotional series. LG long time pioneered the development of the highest contrast monitors with 1600: 1, 2000: 1 and 3000: 1 models.

DFC 5000: 1 technology dynamically controls brightness as the picture changes on the screen, thus ensuring the viewer is at the most optimal brightness level. This means that LG monitors are capable of viewing movies that sports programs or TV at the level of the most high-tech TVs.
