Notebook External monitor FAQ How to solve

notebook computer external monitor becomes the trend. Compared to desktops, laptops have a greater advantage in portability and energy saving, and as notebook performance improves and their prices are lowered, more and more Office users and students are taking laptops as their preferred option. Because the laptop screen size is relatively small, so many consumers are external to a liquid crystal display, to increase the efficiency of work and learning.

In addition to increasing productivity, laptop external monitors also have many advantages. Now, the use of laptop external monitors has become a trend.

As a result of the use of notebook external monitor for dual-screen operation of more and more users, many users will encounter a lot of problems in the external, such as the display after the display, no screen, etc., we also can often see users in the Forum to publish similar posts.

A lot of people will encounter all kinds of problems when they are used in peacetime. In this article, we will list some of the most common problems that users use when using a laptop's external monitor and resolve them one by one.

One of the common challenges--not to display content on the monitor only

Many laptops now have Windows Vista operating systems pre-installed, but because Vista is a resource-intensive system, many users are "upgrading" their operating systems to Windows XP. However, after reinstalling the XP system, many users found that the "only on the LCD display screen" feature, in addition, the monitor, the system does not have any prompts.

An external LCD monitor is typically divided into three modes: The screen is displayed only on the monitor, the laptop or monitor screen is the expansion screen, and the laptop screen and monitor screen display the same content. However, many netizens installed Windows XP, and did not install the relevant drivers for the video card, only using the system's own graphics driver. Under XP, there are not many options for choosing an external mode.

If you are using only the add-in mode adjustment tool with the XP system, we can see only the option to expand the desktop and copy the desktop, to achieve the "display only on the monitor screen" feature, you can only install the latest video card drivers.

Under Windows Vista, even if the user uses the system's own graphics driver, it is possible to transform three external modes with Vista's own add-in.

Now that most users still use Windows XP, so we recommend users to install the appropriate graphics driver, the driver will have a very detailed function, the operation is more convenient. After installing the graphics driver, the problem of "not displaying content on a flat panel monitor" will be solved. For detailed setup information, please refer to the relevant article on the first page of this article.

Note: When installing the graphics driver, we recommend using a WHQL certified driver with good stability. Some beta-driven or even third-party-released drivers may cause the laptop to be external to the monitor blue screen, Huati, and other phenomena.

In addition to the graphics driver, a handful of notebook brands offer several modes of external display options. such as Lenovo ThinkPad Notebook computer, equipped with the relevant control software, operation is also very convenient. However, brands like ThinkPad laptops that offer similar software are, after all, a handful.

Two common challenges--unable to display normal resolution

In the external LCD, sometimes the whole connection process is very smooth, but sometimes there will be more troublesome phenomenon. When the monitor is attached, the best resolution of the LCD is not found, which is one of the more difficult phenomena.

Even if the graphics driver is properly installed, people will sometimes find that the best resolution is not found, such as 1440x900, 1680x1050, and so on, and can only adjust the resolution to 1024x, when the "Show only on display" mode is selected. 768 such a non optimal resolution. This way, the text or picture on the screen becomes blurred or stretched by the inability to achieve a point-to-point display. If you choose a large resolution, the monitor displays an error dialog box with a "out of frequency range".

Users who frequently replace an external monitor may experience this problem. Because of some LCD IC circuit and graphics card compatibility problems, so the first time when the connection, this situation will occur. At this point, we usually just need to reboot the laptop to solve this problem.

Once the laptop is restarted, we can find the best resolution in the option to adjust the resolution. If the best resolution for BenQ 24 widescreen M2400HD is 1920x1080, we can find this resolution option in the above image.

However, sometimes even if we reboot the laptop, we still can't adjust to the best resolution, then reinstalling the video driver will solve the problem, but the probability of this happening is very small. When the resolution is successfully set, the operating system automatically records the ID of the LCD display, so that when the connection is made, the operating system automatically adjusts and does not need to be restarted again.

Three common problems--lingering "water ripples"

It is believed that many consumers who use liquid crystal displays have encountered the phenomenon of "water ripple". At first, many people think that the "water ripple" phenomenon is entirely due to the LCD display or the quality of the graphics card is not the result of the clearance. Many people still experience this phenomenon when they are using a laptop computer to add a monitor.

In the appearance of "water ripple" phenomenon, many consumers in the forum after the vent, the display will be sent to the aftermarket repair center, the results were told that the LCD has no quality problems. In fact, there are many reasons for the "water ripple" of the display, and most of them are not caused by the LCD itself, because the quality of the video signal line or the contact is not very good.

Currently, most laptops on the market are equipped with only d-sub interfaces, with only a handful of models, such as the Dell part of the XPS series, the Sony VAIO FZ series, and the upcoming Lenovo ThinkPad SL series laptop with an HDMI interface. Because the liquid crystal display is transmitted through the analog D-sub interface, it is more susceptible to the interference of the surrounding electromagnetic waves, especially when using large size liquid crystal displays larger than 22 inch widescreen, the water ripple phenomenon will be more obvious, so it is very important to choose a good d-sub signal line.

In addition, because analog signals are susceptible to interference, we recommend that you use a monitor to stay away from intrusive devices. In addition, many users in the external LCD display, in order to map the convenience, just the signal wire simple and the monitor to connect, and did not tighten the interface end of the screws, we recommend that users in use, the interface behind the screws with the LCD monitor or laptop connection end tightening, In order to avoid the interface loose and cause the screen color or other abnormal phenomenon.

Four common challenges--how to close a laptop lid on an external monitor

Many users in the external display, will choose "only on the display screen display" this mode. After using this mode, the laptop screen is turned off, and many users want to put the laptop lid together, which can effectively prevent dust from entering. However, since most laptops are automatically on standby after closing the lid, how do you close the laptop lid while the external monitor is plugged in?

We can solve this problem by adjusting the power options for the notebook computer. Let's now demonstrate how to set the Power options under Windows Vista operating system to do this. First, we go to the Control Panel and choose power Settings, and we can see the interface in the image below.

At this point, we can see a series of shortcut setting options on the left side of the menu, which includes the "Select the function of closing cover" option. Next, we click into this setting.

After entering the shortcut settings, we see the option in the Red box above, select "Do not take any action" in the item "Close the lid", and then click Save changes so that the system will not go on standby after the lid of the notebook computer is turned off.

The consumer is reminded that, because after closing the laptop lid, the cooling effect will be reduced to a certain extent, so if you use the notebook computer itself is not good, we do not recommend that you use the lid, because after a long time, the laptop will be due to its own temperature rise and do not work properly. Therefore, this method is limited to the laptop users with better thermal performance. Error in notebook external monitor

In the external display, we recommend that users buy their own keyboard and mouse, so in addition to the notebook computer placed more convenient, but also can increase the comfort of office. But like the picture above the classmate, the use of the notebook's own keyboard is not necessary, so not only to the overall feeling very awkward, and notebook computer and LCD display will be greatly restricted, if the use of the display size is not large, look at the text will be more arduous.

In addition, many display manufacturers have introduced ultra-low-size LCD display, such as 15.4 inches, 15.6 inches and so on. Although these models are not suitable for external display (screen and notebook than the same), but the matching external mouse, keyboard use can prolong the life of the notebook, so this method is also a good way.

Summarize

With the increasing number of users using a laptop external monitor, many users encounter a variety of problems when they use it. Although this article, we do not answer all the problems will arise, but these problems are the most responsive users, with a certain degree of universality.
