It is such a waste to only use the LCD for desktop computers. Connecting it up with a laptop PC has many merits for the user and can also bring out the latent power of the laptop.

Note: Below is the translation from the Japanese of the ITmedia article "The dual display in Windows 7 is now even more convenient" published March 1, 2010. Copyright 2011 ITmedia Inc. All Rights Reserved.

Most laptops have a handy "external display output" port. It can be used in the home to transmit videos played on the laptop to a large screen TV or, in the office, to connect up with a projector for presentations. In fact, there must be many users who already use it like this. However, people tend to use just the laptop in their daily routine and there are probably not so many cases where they use the external display output.

A laptop can be put to more effective use if it is connected to an external LCD. The photograph shows an EIZO 23-inch wide-screen LCD connected by HDMI to a Sony VAIO C laptop (VPCCW28FJ/R).

This time we would like to suggest a style that can be used in both the home and the office, where a laptop and stand-alone LCD remain connected. A laptop already has an LCD, but using it with an additional stand-alone LCD offers various merits. Not only does it make the laptop environment more pleasant and convenient, it also expands the potential of the computer itself, for example by making it possible to use it for new purposes.

Even if the LCD is already connected to a desktop computer and being used for something other than the laptop, most monitors nowadays have two or more video inputs and they tend not to use this capability to the full. It is such a waste to let the laptop"s external display output function and the monitor"s video input function remain dormant, so we would like them to be put to effective use. Of course, we would also recommend the introduction of a new LCD to connect to your laptop.

The biggest merit of connecting a laptop with a stand-alone LCD is that it gives you a large screen and high resolution dual display environment. Standard laptop models usually come with a built-in 13-inch to 15-inch wide-screen LCD with a 1280 × 800 dot or 1366 × 768 dot resolution.

This level of resolution is good enough for basic Windows operations, but it goes without saying that a large, high-resolution computer screen is much more user-friendly. Combining a laptop with one of the latest wide-screen monitors enables you to easily construct a large-screen, high-resolution dual display environment. It is a real boon to dramatically boost the screen size and resolution while continuing to use your familiar laptop.

In particular, the increased vertical resolution makes applications such as web browsers and document display and editing far easier to use. For example, you can do things like check things with the web browser, refer to pdf files, organize data using word processing or presentation software, and create spread sheets and documents without having to change windows.

Another plus is that you can create the luxury of a "watching while" environment where you run the web browser, for instance, on the laptop"s built-in LCD and watch the video content on the large screen of the external monitor. This can be really useful for hobbies too. For example, while playing a game on the large external LCD screen you can check out strategies on websites, post information on a BBS or communicate with other users.

You can smoothly use multiple applications at the same time in the large workspace provided by a dual display. The photograph shows an EIZO 24.1-inch wide-screen LCD, the FlexScan SX2462W connected to a VAIO C. By supplementing the laptop"s built-in 1366 × 768 dot 14-inch wide-screen LCD with a 1920 × 1200 dot 24.1-inch wide-screen, it is possible to show more data at a time, a huge boost to work efficiency.

With two screens it"s easy to have full-screen display of the video content on one screen while you operate the computer on the other. The photograph shows an EIZO 23-inch wide-screen LCD monitor connected to a VAIO C. The VAIO C has HDMI output and the LCD monitor has HDMI input so visuals and sound can be transmitted by a single HDMI cable. The LCD monitor has full HD screen resolution (1920 × 1080 dot), making it the perfect match for HD video content.

At the office, it is very helpful for presentations to use "clone view" for the laptop"s built-in LCD and the external LCD screen. Clone view means showing exactly the same content on two display screens. It is normally set by a graphics driver function.

When holding small meetings it is certainly very convenient to be able to offer simple explanations of the presentation materials displayed on the external LCD, rather than having to ready a projector. Being able to explain about what is displayed on the screen means fewer documents to distribute, helping your office to "go paperless", which can only be a good thing.

We would like to point out here that you should check in advance the maximum resolution that the laptop"s external display output can handle. This can be found in documents such as the laptop"s specifications chart and support information. This is because, although most laptops can handle output up to 1920 × 1080 dots or 1920 × 1200 dots, some slightly older computers have an upper limit of 1680 × 1050 dots or 1600 × 1200 dots.

Even if the upper limit is 1680 × 1050 dots, the LCD can still display the data if its own resolution is 1680 × 1050 dots or higher. In such cases, it is better to use a monitor that offers dot-by-dot display, which displays the input resolution as it is, or enlarged display, which maintains the screen"s aspect ratio as it is. You do not need to worry because EIZO wide-screen LCDs can handle such display methods (although in some cases they do not function properly depending on the laptop computer or input resolution).

This is an example of a low-resolution display on the 1920 × 1200 dot display SX2462W. Since dot-by-dot display outputs the physical "1 dot" of the LCD and the input resolution "1 dot" without enlargement or reduction, it is shown small in the center of the screen (photo on the left). The display is a little blurred if it is enlarged while maintaining the aspect ratio, but this method is suitable for displaying images as they are shown large with low resolution to make the most of the screen size (photo on the right). Many monitors that cannot handle such display methods enlarge the display to full screen regardless of the input resolution. In such cases you have to be careful as the aspect ratio of the image is altered (for example, people appear to be thinner or fatter).

It is easy to set up a dual display in Windows 7. A menu is displayed when you right-click on the desktop. From "Screen resolution" it is possible to detect and align the external LCD, and set details such as resolution, display method and which will be the main display screen.

The "Screen resolution" menu. If the external LCD is not automatically recognized, click on "Detect". After the monitor has been recognized, you can select the display mode from the "Multiple displays" drop-down menu. Select "Extend display screen" to make the laptop screen and the external LCD into a single display screen (dual display).

Select "Duplicate display screen" from the "Multiple displays" drop-down menu to display the same content on the laptop screen and the external LCD screen (clone view). With this drop-down menu you can also set it to display video on one of the LCDs.

You can also call up a settings menu to decide the display method for a projector or external display by pressing the "Windows" and "P" keys. This is a tip worth remembering as selecting "Extension" for dual display or "Duplicate" for clone view here allows you to switch swiftly between them as necessary.

The menu launched by simultaneously pressing the "Windows" and "P" keys. You can easily switch between display methods such as dual display or clone view.

It is also worth noting that Windows 7 has added functions so that dual display can be used more effectively. An active window can be moved to the screen of another LCD by simultaneously pushing "Windows" + "Shift" + "→" (or "←"). It is also possible to maximize the window by pressing "Windows" + "↑", minimize it by pressing "Windows" + "↓", and shift it to the left or right of each screen by pressing "Windows" + "→" (or "←"). Making good use of these shortcuts should enable the efficient placing of windows in the two screens.

In Windows 7, pressing "Windows" + "Shift" + "→" instantly moves the active window from the left-hand screen (photo on the left) to the right-hand screen (photo on the right). Conversely, you can move the active window from the right-hand screen to the left-hand one by pressing "Windows" + "Shift" + "←".

We would recommend a wide-screen model with a screen resolution of 1920 × 1080 dots (Full HD) or 1920 × 1200 dots (WUXGA) as the LCD to connect to a laptop, so that you can make full use of the advantages of dual display. EIZO has an extensive line up of wide-screen LCDs which can offer many benefits, in addition to the merits of a large screen and high resolution, when used with a laptop for dual display.

One such feature is the flexible stand adjustment. For example, the tilt, swivel and height can be adjusted for the FlexScan SX2462W, a 24.1-inch WUXGA model, and the FlexScan EV2333, a 23-inch full HD model. This enables users to adjust the screen position for easy viewing according to their own posture, which not only boosts work efficiency but also reduces physical strain.

The SX2462W stand. The simultaneous adjustment of its tilt, swivel and height enables the optimum screen position to be aligned for its operating environment.

The SX2462W is also equipped with vertical display function, turning the screen through 90 degrees. Vertical display is really handy when viewing elongated documents, graphics or web pages. In addition, when used as a standard horizontal screen, a 24.1 wide-screen, with its 518.4 × 324.0 mm display area, can display two A4 sheets, in other words one A3 (420 × 297 mm) in actual size. As well as being very useful in areas such as graphics or desk top publishing, this is also bound to come in handy when checking large business or accounting documents.

Setting the connected monitor into a vertical position is very convenient when displaying elongated web pages and documents or photographs that were taken vertically

With a 24.1 inch wide-screen like the SX2462W, an A3 sheet (two A4 sheets side by side) can be viewed in actual size, particularly effective for paper-based creative work ITmedia LCD Course II, Lesson 3: Which is better, 16:10 or 16:9 ? – "Screen size / resolution / aspect ratio"

We must not forget that EIZO"s wide-screen LCDs have non-glare screens (processed to reduce ambient light reflection). Nowadays the trend is for laptops to have an LCD with glare (glossy) surface treatment. While these can display images in bright color, reflected ambient light can sometimes be distracting.

A laptop screen is not so large and adjusting its angle can avoid the reflection of lights and so on, however it is not so easy with the large screen of an external LCD. When it comes to the large screen of an LCD in habitual use, a non-glare type that is not reflective is probably easier to see, as well as being kinder on the eyes. A large screen, high resolution and non-glare ensure that you can comfortably continue viewing over a prolonged period of time.

The surface treatment of an LCD makes a difference to the background reflection. Glare panels do not diffuse background light, making it easier to achieve high color purity, but easily reflect the user or lights (photo on the left). If the lights are similarly trained on a non-glare panel they do not have much effect, only appearing as a fuzzy brightness (photo on the right).

Another distinctive feature of EIZO wide-screen LCDs is a commitment to energy saving. They incorporate various power saving features that support "EcoView". A pivotal feature is the "EcoView Sense" adopted in the FlexScan EV series, such as the EV2333W.

This is the motion sensor on the front of the LCD. It constantly monitors the user"s movements to automatically take finely-tuned power saving measures. To be more precise, if the user"s presence is not detected for a specified period of time, for example if he leaves his seat, the monitor automatically switches to power save mode, and then automatically switches back when the user"s presence is detected again.

Other features include "Auto EcoView", which automatically optimizes the brightness of the LCD based on ambient lighting, and "EcoView Index", which displays a meter on the screen showing how much power is being saved. All these features can be expected to have a strong energy saving effect and to boost the user"s awareness of power saving, making them particularly useful in the office.

A standard laptop computer switches to sleep mode if the built-in LCD is closed while it is running but, if this function is turned off, a laptop can be treated as a "small desktop computer."

It can be set to use only the connected external LCD and not to react when the laptop"s built-in LCD is closed. The transformation into a small desktop PC is complete if you add a keyboard and mouse connected to the laptop via USB ports, for example. The OS is still running even though the laptop"s built-in LCD is closed, so you can carry out normal operations using the external keyboard and mouse, and also use the laptop"s built-in optical drives.

The idea is to use a large screen, high resolution external LCD at home or in the office, and to use the laptop"s built-in LCD as usual for mobile purposes. This helps to boost the longevity of the laptop"s built-in LCD and many people do use their laptop in this way. If you feel reluctant to use a dual display environment, where the screen is split in two, why not give this a try?

Select "Only show the desktop on 2" from the "Multiple displays" list in the "Screen resolution" menu. The laptop"s built-in LCD will be switched off and the external LCD will become the main display.

In the case of Windows 7, open "Alter power button operation" from the "Power options" list in the Control Panel"s "Hardware and sound", and alter the "Operation when the cover is closed" to "Do nothing".

By making this simple setting your laptop can be used as a space saving desktop computer. Another plus is that the laptop"s built-in LCD will last longer.

Recently some high-end laptop computers, such as the Sony VAIO F, are insisting on good display quality for their LCDs. However, a typical laptop"s built-in LCD does not have as good image quality as a stand-alone LCD. This is only natural since the costs allowed for display quality are completely different for an LCD incorporated into the PC as one of its parts and a specialized LCD.

However, by using an EIZO wide-screen LCD a laptop user can still fully enjoy such benefits of a stand-alone high-quality LCD as excellent color reproduction, a wide viewing angle, more even display and a wealth of items that can be adjusted to improve image quality. This is a crucial point for people who use their computer for photographs and videos in particular.

EIZO"s wide-screen LCDs emphasize color reproduction, and the coloration in sRGB mode has a high degree of accuracy. The standard color gamut used in PC environments and Internet content is sRGB, so you need have no worries about viewing or editing videos and photographs. They can also display images on web pages, such as products in online shops or goods for sale in online auctions, in colors that are very close to the real thing. (This is also influenced by how the seller took the photographs and processed the images, so we cannot say that the colors will always be accurate.)

Furthermore, in addition to sRGB color gamut accuracy, the high resolution-oriented FlexScan SX has the added benefit of covering more than 95% of Adobe RGB. Adobe RGB is a color gamut whose definitions encompass more highly-saturated colors than sRGB. In other words, it can represent a larger number of colors and brighter hues than sRGB.

Adobe RGB is the de facto standard in the publishing field and, closer to home, is used in digital SLR cameras and high grade compact digital cameras. The FlexScan SX series can reproduce the colors of photos taken in Adobe RGB mode with almost perfect accuracy on the screen. Retouching photographs proceeds more efficiently since subtle differences in color can be checked on the screen.

An example of sRGB color gamut image data displayed on a standard laptop and on the SX2462W. The SX2462W"s reproducibility of sRGB mode is of a considerably high standard but the color balance on the laptop has been lost. This would make it difficult to perform rigorous photo retouching.

In this case, if the image is edited on the external LCD with its high color reproducibility and the many tool palettes in the application are grouped in the laptop"s built-in LCD, there is less need to display or hide the tool palettes or to switch back and forth, and the image data to be edited can be displayed in a large form, making for more efficient work.

In this case, if the image is edited on the external LCD with its high color reproducibility and the many tool palettes in the application are grouped in the laptop"s built-in LCD, there is less need to display or hide the tool palettes or to switch back and forth, and the image data to be edited can be displayed in a large form, making for more efficient work.

When doing things like photo retouching, using software where there is a lot of switching between tool palettes it is very handy to display the image data to be edited on the external LCD with its high color reproducibility, and to gather the palette tools to be used on the laptop"s built-in LCD.

Going back to the subject of laptop computers, it is not going too far to say that applications and functions are being spoiled in laptops whose built-in LCD"s image quality is not too good. Connecting a laptop to a monitor with high image quality dispels any concerns about work that deals with colors and also helps to bring out the laptop"s potential.

Combining an EIZO wide-screen LCD with a laptop computer makes viewing videos and images even more fun. Just being able to see them on a large screen is a pleasure, but what makes it even better is that our LCDs are equipped with Fine Contrast, the optimum image quality mode for video and visuals. You can also use the Custom mode to create the image quality you prefer.

We expect that you now understand how displaying screens from a laptop computer on a stand-alone LCD can create a very pleasant environment. It feels as if your everyday laptop has been transformed into a completely different desktop machine. Even if you only use laptop computers, it is definitely worthwhile to add a stand-alone LCD.

When choosing the type of LCD the most important consideration is to choose one with overall high quality. When it comes to that, we can recommend EIZO wide-screen LCDs to a broad range of laptop users. In addition to their high image quality, EIZO wide-screen LCD are built with careful attention to detail, including non-glare screens, versatile stand features, dot-by-dot capability, abundant image quality modes, and our proprietary eco-functions. We want you to make full use of your beloved laptop computer along with an EIZO wide-screen LCD.

This time we have spoken about how an external LCD can be connected to a laptop computer, but if your main machine is a desktop computer then you probably already have a LCD.

In which case, why not consider adding a full HD (1920 × 1080 dot) or WUXGA (1920 × 1200 dot) wide-screen LCD and creating a more advanced dual display environment to further enhance your computer"s usability.

Recently many computers can handle dual display output with their chipset integrated graphics function, and nearly all of them are capable of dual display output with a stand-alone graphics card.

The dual display environment of a desktop PC has a wider range of options than a laptop computer, which is already installed with an LCD. Depending on the combination of products used you can seek for a larger screen, higher resolution and better image quality.

The photograph below shows two EIZO 24.1-inch WUXGA (1920 × 1200 dot) models being used side by side for an overwhelming super high resolution of 3840 × 1200 dots in total.

You can get a super high resolution of 3840 × 1200 dots in total by putting two 24.1-inch 1920 × 1200 dot wide-screen LCDs side by side. The advantage in this is that a larger screen and higher resolution are achieved at a lower cost than buying a single 30-inch high resolution model

Unyielding commitment to quality and customer satisfaction has driven Dell to offer a Premium Panel Exchange as part of the standard limited hardware warranty. Even if one bright pixel is found, a free monitor exchange is supported during the limited hardware warranty period.

Premium Panel Exchange is available for Dell Consumer, Professional, UltraSharp, and Gaming (including Alienware) monitors that are sold with computers or as stand-alone units, with a standard 1-year or 3-year limited hardware warranty. Customers who purchase an extended warranty can benefit from this coverage during the limited hardware warranty period.

Dell recommends ensuring that the device drivers and BIOS are up to date using the SupportAssist application for optimal video performance and to help resolve common video-related issues.

NOTE: When SupportAssist does not show up in the search results, go to the SupportAssist for PCs and tablets page for information about downloading and installing SupportAssist.

To learn how to manually download and install a device driver such as Chipset, Video card (GPU), and Monitor driver (if required, most monitor drivers are delivered automatically through Windows Update) on your Dell computer, see the Dell knowledge base article How to Download and Install Dell Drivers.

We must verify whether the problem is the display screen of the laptop, video card (GPU), or video settings on the computer. A straightforward way to identify this is to connect the laptop to an external monitor or TV.

If the issue persists on the external monitor, it may be an issue with the video card (GPU) or video settings and not the laptop LCD panel. Go to verify display or video issues in Windows Safe Mode. Otherwise, go to the next step.

Performance issues may occur if there is any damage to the LCD screen. The display may stop working, work intermittently, flicker, display horizontal or vertical lines, and so on, if there is damage to the display screen.

If you notice a physical damage, contact Dell Technical Support to learn more about repair options that are available in your region. If there is no damage, go to the next step.

Dell laptops have integrated diagnostic tools that can determine if the screen abnormality is an inherent problem with the LCD screen of the Dell laptop or with the video card (GPU) and computer settings.

When you notice screen abnormalities like flickering, distortion, clarity issues, fuzzy or blurry images, horizontal or vertical lines, color fade, running a diagnostic test on the LCD helps identify if the issue is with the LCD panel.

Press and hold the D key and turn on the computer to enter the LCD built-in self-test (BIST) mode. Continue to hold the D key until you see the entire screen change colors.

If you do not detect any screen abnormalities in the integrated self-test mode, the LCD panel of the laptop is functioning properly. Go to the Update the video card (GPU) driver, monitor driver, and BIOS section.

If you notice any abnormalities in the LCD built-in self-test mode, contact Dell Technical Support to learn more about repair options that are available in your region.

Windows Safe Mode does not load any drivers, startup applications, third-party services. This will help us identify if the issue is related to the operating system, video settings, device drivers, or third-party software. To learn how to boot your computer into Safe Mode, see the Dell knowledge base article below based on the operating system that is installed on the computer:

Windows updates can support your Windows operating system in many ways. Windows updates can solve specific problems, provide security patches and protection from malicious attacks, or even add new features to the operating system.

Display settings like brightness, refresh rate, resolution, and power management may affect the performance of the LCD screen on your Dell laptop. Changing or adjusting the display settings can help resolve several types of video issues.

NOTE: Depending on the model of the Dell laptop, the shortcut keys to adjust or change the brightness may differ. See the User Guide or User Manual of your Dell laptop for model-specific information.

If you find that the Dell laptop is unresponsive to touch, touch stops working entirely, or other touch-related issues, you can try some common troubleshooting steps to help fix the touch-related issue.

Stress Test can thoroughly diagnose the video card (GPU) on your computer and report any potential hardware problem. Running a stress test on your computer can verify if the hardware components are stable and thus reliable.

System Restore is an integrated Windows tool that is designed to protect and repair the operating system. When something goes wrong with your computer, System Restore must be used before you try to restore the operating system to factory default settings.

If the diagnostic tests on the LCD panel and the video card (GPU) passed, it is most definitely an issue that is related to software that is installed on the computer. If the above troubleshooting steps did not resolve the issue, you may try to restore the computer to factory default settings as a last resort.

WARNING: Restoring or resetting the computer to factory default settings will erase all personal data on the computer. Back up all important data like documents, images, music files, spreadsheets, videos to an external hard drive or a cloud-based backup like Microsoft OneDrive.

Dell computers are built with a small amount of hard disk space that is reserved for reinstalling the operating system. This method is the easiest way to restore the computer to factory condition. The restoration process deletes all user data from the computer, so be sure to back up all your files before starting this process.

I like using a bowl for keeping my screws as I work. I"m looking for a small stainless steel bowl to use, and I plan to epoxy a large magnet to the bottom to make the screws stay put even if the bowl gets bumped.

Even better, use a muffin tin. There are 12 or so individual small bowls that are permanently attached. You can use them in order of disassembly and use the bits in the reverse order as you reassemble. A strip of masking tape along the one edge of each bowls makes a quick and simple labeling system.

I learned this simple trick from an airplane mechanic I used to work with. As we took inspection panels and other parts off the planes, you just placed the screws and other fasteners in the bowls.

I use a egg box (carton?) for 24 eggs. I wrote the numbers from 1 to 24 in the bottom of the bowls. And sheet of paper in which I write the number of the bowl and What I out in it. Hm. Took a Picture of it, but can"t seem to attach a picture with the mobile site.0

It"s easy to make a quick sketch of the equipment your are disassembling too. It is a technical"s usual practice to make sure things will go the right places again... I"ve learned it from a friend who"s a CASIO technician, and show this to a Japanese teacher from CASIO JAPAN... The guy never thought it could work so well...

That"s the instructables iron ;) It"s a Hakko something or other - I think it"s a Japanese company/brand but very well may be manufactured in china :p

I did this one on a Dell 5150 with a 15" UXGA screen. It can be very very tricky to get that reflector back into place because you"ve got the lamp in there and don"t want to break it. Meanwhile, you need to slip it around the thick (quarter inch) glass behind the LCD so that the light shoots up through the glass. The lamp has high voltage so you want to make sure there are no exposed wires. Those silicone rubber end caps might be torn after you get the thing apart.

Bottom line, it can be challenging and you need good eyes and careful fingers to get it all back together just right. I felt lucky to have been successful.

I got my LCD out and on the back it said "DO NOT TOUCH WHITE TAPE --- SENSITIVE AREA." Unfortunately, I had touched that tape when I flipped the LCD over to the back. Fortunately, it does not seem to have been damaged.

Look up CCFL (cold cathode fluorescent lamp) to find a supplier. You should not need to spend more than $15 + $7 shipping. But I would strongly recommend ordering new end caps and wire to make the job easier and safer. You"ll still save at least $100 in labor.

Good tip.  The LCD doesn"t seem to be damaged because if you took off the white tape, there is a thin ribbon cable there.  This cable contains millions of tiny wires (3 per pixel) and at one point, right before it goes into the LCD, becomes so packed the wires seem to come together into a rectangle (they"re indistinguishable).  They don"t want these to break or short.  However, if you"re careful, I found this cable can survive quite a bit of bang. =P (I took apart one of those LCDs completely).

So, by having low energy requirements, you save on battery power and can use a smaller pack - which saves on cost in that area. The bulb itself is cheap, but the inverter is a little more expensive. Fluorescent tubes have a pretty uniform light output - so I"m not sure why you"d think it is uneven. Perhaps you"re thinking it to be more like an incandescent?0

Opps didnt read #8 so the glass diffuses the light evenly i thought they just like had a a bulb going across the screen and that would make it uneven (i have 6 hour jet lag at the moment so im not thinking strait JSYK)0

The inverters in these monitors are always failing because of a design flaw, or rather cheap out. There are 4 transistors that are really hard to get that fail because they are not on a heatsink and wear quickly. Anyhow I decided that it was not worth fixing the inverter and instead found a couple of old point of sale touch screen machines. (486 mi-cos yuk) they had a really nice modular inverter that sported just 5 pins kinda like a square chuck of black epoxy with pins sticking out. these things are great it is too bad they don"t use them today anymore but then again they are manufactured in Canada so go figure. if you happen across any of these old point of sale machines it is worth digging out the inverter module because you never know when you are gonna need 1500 volts...

i Got Myself an Old laptop With a Broken Screen, I Opened the Screen And Took Out the Backlight And the Inverter, Coincidentally I had another Old laptop,That Was A Similar Model,It had the Same Inverter And Cable,So I Tested the CCFL tube from the laptop with the broken screen and it worked,The Inverter+CCFL Worked Like a charm,Now I am Making Myself a lamp,I got that thing to run off of a 9V Battery,And a 13V Power source.0

Before buying your replacement light,measure it!I found there are big differences in what they say the size is and what it really is.Example inspiron 1200 is said to have a 15 inch when its really 11.5!The light sellers even have it on their sites as 15 so double check!

Even if you are extremely careful with your hardware, it can be unavoidable at times to run into issues such as a cracked or broken computer screen. Just because you’re experiencing problems with your display doesn’t mean that your laptop is beyond saving, however.

You should also know that repairing your laptop screen isn’t always the easiest job, and there is a possibility you can make the problem worse while voiding the manufacturer warranty. It’s important to feel confident in your skills before you begin the process of replacing your screen, and to consider if you would be more comfortable taking it in to a qualified repair shop.

Even those who have never replaced a screen can manage to do it depending on the type of computer. Just be aware that if you own a laptop with a touch screen it can make the process much more challenging.

If you’re wondering about broken laptop screen repair costs, you’ll be happy to know it’s not as expensive as you may assume. Professional repair costs are usually around $300 or so [1]. If you are comfortable working on your laptop yourself, you can usually find replacement screens online for reasonable prices - sometimes as low as $50 to $100 - and it often only takes an hour or two to complete the replacement job.

If you’re willing to take the leap and do this yourself, then you can end up rescuing a computer you may have thought you needed to replace. Here are 5 steps you can take to successfully replace or repair your cracked computer screen.

Before you begin the process of changing your screen, it’s important to know exactly what’s wrong and what needs to be repaired. The type of device you have can influence how much you’ll have to pay for another screen, as will its age, which may make finding a replacement rather difficult. You should do some research online to find out if you even have the option to fix the screen yourself.

The first step is making sure the device powers up successfully and that the screen is the only issue you need to address. As a test, hook your laptop up to a separate monitor. If your laptop seems to function well, then it’s likely that the broken laptop screen is all you have to worry about. Keep in mind that some laptops need to have some function keys pressed in order for an external display to work properly.

You will also have to do a complete inspection of your computer to determine if your screen is the only problem. A destroyed graphics card or a computer that refuses to start up indicates that a new screen isn’t enough to get you up and running again.

Also, if the frame of your laptop has suffered physical damage, then you may have some difficulty repairing your screen. Once you have looked over your device and determined whether you can fix it on your own, it’s time find the right screen for your computer.

Note: If you’re concerned about your laptop’s touch screen repair, it can be more complicated to fix this problem without professional help. These displays are designed with factors like sensitivity in mind, so it’s a good idea to have an expert take a look at it, even if it means spending a bit more than anticipated.

One of the main reasons you should know the model of your laptop is so you’re sure that you’re purchasing the correct replacement screen. While a number of companies offer laptop screen repair kits that can make the process easier, if you order the wrong screen you won’t be able to make any repairs. If you’re having difficulty figuring out your computer model, you can visit the “Settings” menu and find the serial number to assist you in your search.

Fortunately, finding the right screen for your device doesn’t have to be stressful. Often you can find what you are looking for simply by entering your laptop model number into the search bar of online retailers. You may also want to include the search term “LCD” in order to narrow down the accessories that are available for your computer. For the most part, screens should be priced fairly reasonably and you may even be able to buy some for around $50, although it depends on the type of computer you have.

Some sellers may use another form of identification for the model of your laptop, so double check that you chose the right option before you purchase. Almost all the information you need should be displayed on the seller’s listing. Again, take the time to compare your device’s specs with the screen you’re purchasing, and also make sure that the video cable on the back of your screen matches what the vendor shows online. Most of the time, it’s fairly easy to know if the right screen is available.

You will need a few tools in order to properly install your new screen. These tools can make the process much simpler and allow you to fix things efficiently.

Screen repair kits are also available for certain models, so it can be worth it to research your type of computer and see if they’re available. These kits provide you with everything you need ahead of time so you can get to work and not worry about missing an essential tool. Of course, items around your home can work just as well while saving you a bit of money.

Once you have assembled the tools you need to replace the screen, you can get to work repairing your device. Lay the closed laptop on the flat surface you have chosen and keep your tools nearby.

First, turn off your laptop and make sure that it is unplugged from a power source to avoid any risk of electric shock. After that, it also helps to remove the battery to avoid causing any other issues.

Once you have done that, you should identify the stickers that cover screws on the screen bezel. You can usually find them near the bottom of your screen where the hinges would be when you have your display opened. There should be two.

From there, you will need to use a pin to remove the stickers located on the bezel so you don’t end up damaging them. You will need to use these later, once your screen is properly installed, so make sure they aren’t lost and that you store them sticky side up so you can reuse them. Put them in a safe spot so when you go to attach your new screen, they are easy to find.

You’ll then want to use your screwdriver to remove the screws that are now visible. You may have some difficulty depending on how tightly they were screwed in during manufacturing. For the most part, if your old screen is aligned fairly well, it shouldn’t be too much of a problem to remove the screws. Place them in the dish so you don’t lose any.

It’s now time to gently remove the bezel. Make sure you are careful when removing your old screen’s bezel because you will need to reinstall it once the screen is replaced. By using a putty knife or other flat object, you should be able to pry your screen from your laptop case.

It may take a little effort to completely remove it. And don’t be alarmed if you hear some plastic snapping - that is the unfastening of the plastic tabs that hold your screen onto your case. If you have some trouble removing the old screen, the screws at the bottom might not be loosened enough, so stop and loosen them some more before trying again.

One of the trickier parts of replacing your laptop screen will be removing the LCD. First, make sure that the bezel is completely off so you can have unfettered access to the LCD screen. It will be secured onto the laptop’s metal frame, and you will have to take it off from the left and right sides.

There will be two more screws to loosen at the top corners before you can lift the screen slightly away from the metal frame. You’ll probably find a few more screws securing the LCD on the sides, and these will also need to be unscrewed. In some cases, heavy duty tape may have been used instead.

After you remove the attachments, your screen should now lie on your keyboard. It can be a bit of a challenge to make sure there is enough space between the LCD and the metal frame, but you should be gentle to avoid ruining the video cable that runs from the back of the screen to the body of the laptop. If this is damaged, you will need a professional’s help to repair it.

Now it’s time to disconnect the cable from the LCD. You can usually find the connectors in the center, though they may alternatively be located at the bottom of your screen. It’s likely that adhesive was used to connect the two, so you will need to gently pry one from the other. There may also be some tape that needs to be removed, but overall it should be pretty simple to disconnect your LCD from the video connector. Set it somewhere away from your tools.

As you remove the screen, you should be able to locate where your new one will go. Place it face down within the frame so it fits perfectly. After that, you can reattach the video connector so it is placed exactly where the previous LCD sat. Make sure that it is as aligned as possible then attach it with tape or adhesive.

Once that’s done, make sure the sides are secure. Reinsert the screws on the sides and top, or reattach any tape that was used to hold everything together. After everything is nicely tightened, you can put the bezel back on. Line it up so that it snaps properly into the screen case and won’t be easily loosened.

Reinsert the remaining screws into the bezel after you’re certain everything is snapped correctly into place. You shouldn’t be able to see any cracks at all along the edges of the screen. Once the screws are inserted, reattach the screw covers using your pin or needle.

From there, you should be ready to restart your computer. Put the battery in and connect your laptop to a power source before turning it back on. If there is no display, then you will need to double check that everything was properly put back together.

Repairing a broken laptop screen doesn’t have to be done by a professional. If you have the time and interest, then you can end up saving a lot of money by doing it yourself. By following these DIY steps, you can have your laptop display back up and running in an hour or two.

It is an unfortunate fact, that there are many people out there who are ready to throw accusations around based on absolutely no research whatsoever. From time to time, we have been accused of sending fake, or cheap copies (usually from China), of original screens out.

To produce a piece of hardware as complex as a flat screen, you need a very serious setup. The facilities that these devices are produced in are clean room environments. This means they are completely dust free. Workers are usually kitted out, like astronauts, in protective white suits and head gear, to ensure that no contamination can enter the complex layers of glass and reflectors that are assembled to produce the screen.

Obviously there is a huge cost to starting up a production of LCD screens, and for this reason there are less than 10 companies that produce LCD screens, and they are all big players.

So as you can see, the possibility of a company producing knock-off copies of real screens is non-existent. Unless you have 4 billion pounds sitting in your back pocket and a clean room environment occupying several hundred thousand cubic metres, you can forget LCD production.

The reality of the situation however, doesn"t dissuade some people, from throwing wild accusations around, about fake or knock off copies of screens, based on absolutely no research whatsoever.

- The reason for this is that LCD producers are constantly producing new part numbers for their products. They do this to keep their industry moving and their money rolling in. Models they produce are almost identical to each other, yet they keep producing every quarter of a year, a bunch of new model numbers.

Even if your laptop is only 6 months old, it would have been manufactured more than a year ago, and probably the screen inside it is 2 years old. For this reason we will often send you a newer part code, which could be from a different manufacturer. This is perfectly normal and the only way we can provide a service to you.

This is in fact how the original computer manufacturer works as well, as laptops or tablets purchased at different times, will have different brands of screen fitted inside them. This is a good example from a Lenovo brand machine.

We all know how difficult it is to print on non-paper objects, such as a T-Shirt for example. So imagine the difficulty in trying to run a piece of glass through a printer. It would of course require specialised equipment. So then the question becomes, why would an LCD producer invest in specialised equipment to print a code on the screen glass? And why would this have anything to do with the screen being a cheap knock off copy?

Of course, there are some people who seem to be completely devoid of logic and believe that this has happened accidentally due to cheap production methods.

What is actually happening here is that the protective film over the glass has not been removed. Often the LCD producer will kindly shrink-wrap a protective plastic film over the glass so that the screen does not get soiled with finger-marks during fitting. Once fitted this protective film can simply be peeled off.

The usual reaction to this we receive is disbelief, and the assertion that there is definitely no film to peel off the glass. We can tell you with 100% assurance that if you are seeing alphanumeric symbols printed on the glass, seemingly permanent, and visible also when the machine is powered down, you definitely need to remove the protective film!

Lenovo Group Limited, often shortened to Lenovo (lə-NOH-voh, Chinese: 联想; pinyin: Liánxiǎng), is a Chinesemultinational technology company specializing in designing, manufacturing, and marketing consumer electronics, personal computers, software, business solutions, and related services. Products manufactured by the company include desktop computers, laptops, tablet computers, smartphones, workstations, servers, supercomputers, electronic storage devices, IT management software, and smart televisions. Its best-known brands include its ThinkPad business line of laptop computers (acquired from IBM), the IdeaPad, Yoga, and Legion consumer lines of laptop computers, and the IdeaCentre and ThinkCentre lines of desktop computers. As of 2021, Lenovo is the world"s largest personal computer vendor by unit sales.

Lenovo was founded in Beijing on 1 November 1984 as Legend by a team of engineers led by Liu Chuanzhi and Danny Lui.televisions, the company migrated towards manufacturing and marketing computers. Lenovo grew to become the market leader in China and raised nearly US$30 million in an initial public offering on the Hong Kong Stock Exchange. Since the 1990s, Lenovo has increasingly diversified from the personal computer market and made a number of corporate acquisitions, with the most notable being acquiring and integrating most of IBM"s personal computer business and its x86-based server business as well as creating its own smartphone.

Lenovo has operations in over 60 countries and sells its products in around 180 countries.Morrisville, North Carolina, US. It has research centres in Beijing, Chengdu, Yamato (Kanagawa Prefecture, Japan), Singapore, Shanghai, Shenzhen, and Morrisville,NEC that produces personal computers for the Japanese market.

Liu Chuanzhi and his group of ten experienced engineers, teaming up with Danny Lui,yuan.Chinese Academy of Sciences (CAS). The 200,000 yuan used as start-up capital was approved by Zeng Maochao (曾茂朝). The name for the company agreed upon at this meeting was the Chinese Academy of Sciences Computer Technology Research Institute New Technology Development Company.

The organizational structure of the company was established in 1985 after the Chinese New Year. It included technology, engineering, administrative, and office departments.

In May 1988, Lenovo placed its first recruitment advertisement on the front page of the China Youth News. Such ads were quite rare in China at the time. Out of the 500 respondents, 280 were selected to take a written employment exam. 120 of these candidates were interviewed in person. Although interviewers initially only had authority to hire 16 people, 58 were given offers. The new staff included 18 people with graduate degrees, 37 with undergraduate degrees, and three students with no university-level education. Yang Yuanqing, the current chairman and CEO of Lenovo, was among that group.

Liu Chuanzhi received government permission to form a subsidiary in Hong Kong and to move there along with five other employees. Liu"s father, already in Hong Kong along with Lui, furthered his son"s ambitions through mentoring and facilitating loans. Liu moved to Hong Kong in 1988. To save money during this period, Liu and his co-workers walked instead of taking public transportation. To keep up appearances, they rented hotel rooms for meetings.

Lenovo (known at the time as Legend) became publicly traded after a 1994 Hong Kong IPO that raised nearly US$30 millionHK$1.33 per share.HK$2.07 and closed at HK$2.00 suggesting an initial under-valuing of the company. Proceeds from the offering were used to finance sales offices in Europe, North America and Australia, to expand and improve production and research and development, and to increase working capital.

Lenovo released its Tianxi (天禧) computer in 1998. Designed to make it easy for inexperienced Chinese consumers to use computers and access the internet, one of its most important features was a button that instantly connected users to the internet and opened the Web browser. It was co-branded with China Telecom and it was bundled with one year of Internet service. The Tianxi was released in 1998. It was the result of two years of research and development. It had a pastel-colored, shell-shaped case and a seven-port USB hub under its screen. As of 2000, the Tianxi was the best-selling computer in Chinese history. It sold more than 1,000,000 units in 2000 alone.

To fund its continued growth, Lenovo issued a secondary offering of 50 million shares on the Hong Kong market in March 2000 and raised about US$212 million.

Lenovo acquired IBM"s personal computer business in 2005, including the ThinkPad laptop and ThinkCentre desktop lines.US$1.25 billion for IBM"s computer business and assumed an additional US$500 million of IBM"s debt. This acquisition made Lenovo the third-largest computer maker worldwide by volume.

About the purchase of IBM"s personal computer division, Liu Chuanzhi said in 2012: "We benefited in three ways from the IBM acquisition. We got the ThinkPad brand, IBM"s more advanced PC manufacturing technology and the company"s international resources, such as its global sales channels and operation teams. These three elements have shored up our sales revenue in the past several years."

Despite Lenovo acquiring the "Think" brand from IBM, IBM still plays a key indirect, background role in the design and production of the Think line of products. IBM today is responsible for overseeing servicing and repair centers and is considered an authorized distributor and refurbisher of the Think line of products produced by Lenovo.

Mary Ma, Lenovo"s chief financial officer from 1990 to 2007, was in charge of investor relations. Under her leadership, Lenovo successfully integrated Western-style accountability into its corporate culture. Lenovo"s emphasis on transparency earned it a reputation for the best corporate governance among mainland Chinese firms. While Hong Kong-listed firms were only required to issue financial reports twice per year, Lenovo followed the international norm of issuing quarterly reports. Lenovo created an audit committee and a compensation committee with non-management directors. The company started roadshows twice per year to meet institutional investors. Ma organized the first-ever investor relations conference held in mainland China. The conference was held in Beijing in 2002 and televised on China Central Television (CCTV). Liu and Ma co-hosted the conference and both gave speeches on corporate governance.

Lenovo sold its smartphone and tablet division in 2008 for US$100 million in order to focus on personal computers and then paid US$200 million to buy it back in November 2009.¥100 million RMB in a fund dedicated to providing seed funding for mobile application development for its LeGarden online app store. As of 2010, LeGarden had more than 1,000 programs available for the LePhone. At the same time, LeGarden counted 2,774 individual developers and 542 developer companies as members.

On January 27, 2011, Lenovo formed a joint venture to produce personal computers with Japanese electronics firm NEC. The companies said in a statement that they would establish a new company called Lenovo NEC Holdings, to be registered in the Netherlands. NEC received US$175 million in Lenovo stock. Lenovo was to own a 51% stake in the joint venture, while NEC would have 49%. Lenovo has a five-year option to expand its stake in the joint venture.

This joint venture was intended to boost Lenovo"s worldwide sales by expanding its presence in Japan, a key market for personal computers. NEC spun off its personal computer business into the joint venture. As of 2010, NEC controlled about 20% of Japan"s market for personal computers while Lenovo had a 5% share. Lenovo and NEC also agreed to explore cooperating in other areas such as servers and tablet computers.

Roderick Lappin, chairman of the Lenovo–NEC joint venture, told the press that the two companies will expand their co-operation to include the development of tablet computers.

In June 2011, Lenovo announced that it planned to acquire control of Medion, a German electronics manufacturing company. Lenovo said the acquisition would double its share of the German computer market, making it the third-largest vendor by sales (after Acer and Hewlett-Packard). The deal, which closed in the third quarter of the same year, was claimed by

This acquisition will give Lenovo 14% of the German computer market. Gerd Brachmann, chairman of Medion, agreed to sell two-thirds of his 60 percent stake in the company. He will be paid in cash for 80 percent of the shares and will receive 20 percent in Lenovo stock. That would give him about one percent of Lenovo.

In September 2012, Lenovo agreed to acquire the Brazil-based electronics company Digibras, which sells products under the brand-name CCE, for a base price of 300 million reals (US$148 million) in a combination of stock and cash. An additional payment of 400 million reals was made dependent upon performance benchmarks.

In September 2012, Lenovo agreed to acquire the United States-based software company Stoneware, in its first software acquisition. The transaction was expected to close by the end of 2012; no financial details have been disclosed.cloud-computing services. For the two years prior to its acquisition, Stoneware partnered with Lenovo to sell its software. During this period Stoneware"s sales doubled. Stoneware was founded in 2000. As of September 2012, Stoneware is based in Carmel, Indiana and has 67 employees.

Lenovo re-entered the smartphone market in 2012 and quickly became the largest vendor of smartphones in mainland China.iPhone and Lenovo"s desire to increase its market share in mainland China. Lenovo surpassed Apple Inc. to become the No. 2 provider of smartphones in the domestic Chinese market in 2012.

IBM sold its x86-based server lines, including IBM System x and IBM Blade Center, to Lenovo in 2014.Committee on Foreign Investment in the United States (CFIUS) was reportedly the last hurdle for Lenovo, since the United States has the strictest policies. According to Timothy Prickett-Morgan from Enterprise Tech, the deal still awaits "approval of regulators in China, the European Commission, and Canada".

After closing, Lenovo said that its goal was to become the world"s largest maker of servers. Lenovo also announced plans to start integrating IBM"s workforce.

On 29 January 2014, Google announced it would sell Motorola Mobility to Lenovo for US$2.91 billion. As of February 2014, Google owned about 5.94% of Lenovo"s stock. The deal included smartphone lines like the Moto X, Moto G, Droid Turbo, and the future Motorola Mobility product roadmap, while Google retained the Advanced Technologies & Projects unit and all but 2,000 of the company"s patents.

In April 2014, Lenovo purch
