How to adjust the brightness of computer screen

How to adjust the brightness of computer screen? Many netizens feel that the brightness of the computer monitor is too bright, or too dark, want to adjust the brightness, but found no display brightness adjustment method. The brightness of the computer screen also relates to the computer's energy conservation and protection of the eyes, the following system of the small series for everyone to introduce the computer screen brightness adjustment methods.

computer screen brightness is actually very simple, you can choose the computer operating system with the software, you can also use keyboard shortcuts. Now desktop computer is generally selected is a liquid crystal display, the monitor itself has a few adjustment buttons, adjustment is also very simple, do not understand the friend can try their own, very simple, confused, can look at the display instructions.

How to adjust the brightness of the notebook computer screen

If your computer is a notebook computer, you can generally use the keyboard key combination to achieve the adjustment, first you have to look at the keyboard of the FN key and the two signs of brightness, the logo is like a sun, up is the computer screen is lit, down is the computer screen dimming, the general notebook of these two signs are designed on the F key, You can find it carefully, and then press and hold the FN, if you want to make some light, and then press up the flag, if you want to dim, hold down the FN button and then click the downward flag. The Notebook screen brightness adjustment button is shown in the following illustration:

How to adjust the brightness of desktop computer screen

Now we use the desktop computer most of the liquid crystal display, in the bottom of the LCD generally have a few adjustment buttons, specific we can look carefully, there is a main menu button, to find the brightness adjustment options, adjust the brightness, very simple. The LCD Brightness adjustment button is shown below:

The practical effects of desktop LCD display include brightness, contrast, color temperature, resolution, geometric parameters of these basic parameters adjustment.

Brightness--The best brightness

For LCD brightness settings, often need to be based on user preferences, as well as the different circumstances of the surrounding environment. For example, some people are accustomed to the low brightness of the screen, so that the eyes will not be swayed uncomfortable, and some people like to light some, to get a better picture performance. So for the brightness of the setting, you can completely according to their own use habits to set.

And what are the effects of the ambient environment on the brightness of the display? Perhaps everyone has encountered a similar situation, in the late night, turn off the room lights to look at the monitor screen, will find the screen is very dazzling, then must be reduced by reducing the brightness to make the display "soft" some. And that's how the environment affects the brightness of the display. In a dark environment, you need to reduce the brightness of the screen, and in a bright environment (such as outdoors) you need to properly enhance the brightness of the screen to ensure a clearer visual effect.

Contrast--The easiest indicator to make a mistake

High contrast allows the screen to look more detailed and more layered. But the contrast setting is also easiest to let a person "go astray" an indicator, because most people will take it for granted that the contrast setting should be as high as possible, but in fact it is not, because when you overdo the contrast of the liquid crystal display, it will result in the loss and bias of the bright parts of the picture, and the higher the contrast, The more serious the situation is.

The reason is that the increase in contrast when the brightness also increased, but now the liquid crystal display for brightness/contrast balance control is not in place, it led to the above situation. So for the contrast setting, it also needs to be enough.

How do you modulate the contrast to the maximum and make sure the picture is not lost in detail? The simple way is to look at the image to judge, to find a picture you are familiar with (brighter), at this time to improve the contrast of the display, when the bright part of the screen details began to disappear, At this point should not continue to promote the contrast index.

Color temperature--related to the living environment

General display will have several prefabricated color temperature to choose from, Common include 5400K, 6500K, 9300K. The higher the number in front, the higher the color temperature, the more the screen is more inclined to the cold color; On the contrary, the smaller the number, the lower the color temperature, the more the picture will be more warm tone.

It is more customary for us Chinese to set the color temperature to 9300K. This is because the scenery of China all year round the average color Winyo between 8000k~9500k, the display of the color temperature set at 9300K, the screen shows the picture is closer to our real life.

But the color temperature is not an absolute indicator, when we watch the European and American blockbusters, we will find that the screen may be red, warm, if you change the color temperature to 5000 or 6500K will be better, this is because the average color temperature in Europe and America is lower than our customary color temperature, and in the film filming process, The color temperature of the camera will be set at a lower level, thus causing us to not adapt. and to change the color temperature of the monitor will be a good solution to this problem, which is why each monitor to provide a different color temperature options.

Resolution-Standard resolution only clear

Do I need more words for resolution? Maybe you think this is too much pediatrics, but when the author came to a friend's home, found that her 17-inch LCD monitor still working in 1024x768 resolution, then I think of those who are not familiar with the computer, the display of the user, some of the most basic concept is the most important.

So here we need to repeat the standard resolution of each size LCD:

• 15 inches: 1024x768

• 17 inches: 1280x1024

• 19 inches: 1280x1024

• 20 inches: 1600x1200

• 20 Widescreen: 1680x1050

• 23 Widescreen: 1920x1200

Geometry parameter-------don't let characters appear imaginary shadows

Although the LCD is known to have no geometric distortion, but it is only said that it can be horizontal vertical line of the display. In actual use, because the LCD clock and phase may output different steps, it will also bring the characters appear virtual shadow, screen flashing, water ripple problems.

This problem will only appear on the display with analog (d-sub) interface, because the signal attenuation will be generated in the process of analog signal conversion, which leads to the virtual shadow of the character. and digital (DVI) interface due to the full digital transmission mode, effectively avoid the problem of signal attenuation, can more effectively guarantee the problem of picture transmission, and this is our vigorously implement DVI interface is an important reason.

Press the "AUTO" button, you can complete the display of the geometric parameters of the correction

How to determine whether the display of virtual shadow? In fact, it is also very simple, you can carefully observe the display in the text state of the screen, if the text of the gestures hollow, not clear sharp, then you can determine the existence of symptoms. And then you just need to go through the "AUTO" button on the OSD menu to recalibrate the geometric parameters.

On the other problems of liquid crystal display, liquid crystal displays in color and resolution set up different brand and material effect is not the same, specific or according to their use feel to judge.
