There are a number of screen manufacturers. The following link should help. However if you do not want to pull the housing off the screen to find out the manufacturer there is one other way that should work. Download SiSoftware Sandra Lite. It can tell you a great deal about your system. Click on Display and Video Adapters. Then select Monitor Panel from the pulldown menu. It will display the manufacturer. Which, in the case of my Inspiron 5575, is BOE.

On the back side of the screen you can see one or several labels with numbers. Almost every screen on the market today have manufacturer"s code and screen size included in the model number. You will need the manufacturer part number to find the right replacement screen.

For example a Dell XPS 15 (L502X) has a Dell Part Number of VVR75 or 0VVR75, it has an LCD Part Number: XM5XG and a manufacturer P/N: N156B6 -L0B. The Letter N tells us that the manufacturer is CHI MEI and the 156 that this is a 15.6 inch screen.

Below is a list of LCD screen manufacturers with their abbreviations - if you click on the name (in blue) you will see an example of that manufacturer"s parts label.

LG Display is a large South Korean company and the world"s largest LCD maker, followed by Samsung Electronics. Currently, the two companies together control nearly 50% of the global LCD market. LG Display is headquartered in Seoul, South Korea.

Chi mei Part number start with "N". Some Screens have Revision numbers. Like in this example, the part number is N154I2-L02 followed by revision number indicated by Rev.C1. If you had to search for this particular screen on this site, you should search for "CHI MEI N154I2-L02 Rev. C1".

Toshiba Corporation (manufacturing company, headquartered in Tokyo, Japan Toshiba-made Semiconductors are among the Worldwide Top 20 Semiconductor Sales Leaders. Toshiba is the world"s fifth largest personal computer manufacturer, after Hewlett-Packard and Dell of the U.S., Acer of Taiwan and Lenovo of China and US.

Chungwha Picture Tubes, Ltd. (CPT) is one of Taiwan"s, and the world"s, leading manufacturers of thin-film transistor liquid crystal displays, or TFT-LCDs. Ranked number three in the Taiwan TFT panel market.

Sharp, a Japanese electronics manufacturer, has developed into one of the leading electronics companies in the world. LCD technology continues to be a key part of Sharp"s product range, in both the component and the consumer-applicance sides of the business.

Hyundai Display Technology Inc. (HYDIS) of Ichon, Korea, is an industry leader in the development, sales, marketing and distribution of high-quality LCD, which is a spin-off from HYNIX Semiconductor Inc. Boe Hydis (Formerly Hyundai Displays Korea)

Quanta Display Inc. is a Taiwanese company established in 1999, manufacturing thin film transistor-liquid crystal display panels. It merged with AU Optronics.

AU Optronics is one of the top 3 worldwide manufacturers of thin film transistor liquid crystal display panels (TFT-LCD), and is the largest in Taiwan. AUO provides customers a full range of panel sizes and comprehensive applications, offering TFT-LCD panels in sizes ranging from 1.5 inches to greater than 65 inches.

Whether you want to find a replacement for your laptop’s LCD, or know the safest and most optimal monitor overclocking configurations, or just simply know some technical details, you will most definitely need your LCD panel’s model or ID in order to look it up.

This tool gives you a heck ton of technical information about your system. From hard drive models and temperatures to your monitors’ hardware IDs and what not.

Expand the “Monitor” section in the left panel of the window to see your specific LCD monitor. Then, click on the specific LCD monitor to highlight it and show all the technical information of it on the right panel of the window (shown in the above image).

You can see just how many technical details it displays. Out of all this information, your LCD panel’s model will be the first line itself, as highlighted in the below image:

My info did not show up in XOrg.log. But I figured out that I could get the info from the DRM (Direct Rendering Manager) subcomponent of the linux kernel, which is exposed in sysfs. So I did the following:

Once you have found the correct part number, see HP Consumer Notebook PCs - Ordering HP certified replacement parts. Use the instructions in this document to order a replacement part.

Ans: We source laptop screens directly from the manufactures like Samsung, LG, AUO, Sharp, ChiMei, Chunghwa, Toshiba and many more. We only sell genuine high quality screens which are exactly same installed in laptops by laptop manufacturers like Apple, Dell, HP, Sony, IBM Lenovo, Asus, Acer, Samsung, Packard Bell, MSI and Toshiba etc.

Ans:Laptop screen manufacturers release new model (version) of LCD screens from time to time. New model may have better quality, updated electrical parameters etc. As a result, there is may be hundreds of compatible LCD models available in the market. It will require millions of investment to stock every model of the screen. There is also possibility exact model may be outdated and no longer available in the market or price is very expensive.

We offer replacement screens which are 100% compatible with original LCD screen. It may be cheaper in price. This allow us to offer you better deals on new LCD models.

CCFL (Cold Cathode Fluorescent Light - High Intensity Discharge Lamps) was mostly used in older laptops. It comes in two types 1-CCFL or 2-CCFL and also required an inverter to power the lamps. 1-CCFL or “single backlight” contains one bulb to light it up and a pair of wires at the bottom. It has one white inverter connector that is used for plugging into inverter board. 2-CCFL or "dual backlight" contains 2 bulbs, has 2 inverter pair cables as well as 2 inverter connectors.

Ans: Upgrading CCFL to LED backlight is generally not possible. It is so because these screens have totally different connectors and power supplies which makes them incompatible. However, there are cable adapters available that allow LED screen to work with CCFL screen. These adapters are only compatible with certain laptop models. For the rest, in order to change or upgrade CCFL to LED, the motherboard will have to be replaced, which may result even more than the cost of the laptop.

Question:Laptop screen surface Glossy vs Matte? Ans:Laptop screen surface play a key factor while we are doing some professional work on laptop or playing games, watching movies, or sports etc. Laptop manufacture sell laptop with Gloss or Matte finish display depending on type of the laptop. When you purchase a replacement laptop screen, you might be offered with a choice. If original (faulty) screen has matte finish, you can replace it with a new one that is glossy, and same can happen vice versa.

If glossy screens are used in daylight or in very well lit environment then you might not be able to catch a glimpse of what is going on the screen. It is something problematic to use this otherwise valuable version in the screen introduction.

Matte finish allows you to work in bright light, and can be used in daylight as well with quite an ease. It is not going to show you that bright picture if you want to see videos or play games.

All screens are prepared with the finishing touch of Polarized Plastic, and it is the prime factor that determines whether the screen would be glossy or matte at end. The backlighting concept has made glossy screens popular as gloss panels are able to produce sufficient light that there is no room left for the external light that reflects form screen itself.

The fact is that most of laptops come with glossy display now but it doesn’t mean that matte finish is not in demand. You can easily replace one with another.

Laptop manufacturers have given different names for their glossy display. For example, Acer has named its glossy laptop screen as CrystalBrite, Asus, as Colour Shine and Dell as True Life.

Different names are given to different types of resolution by the LCD industry. These are identified with abbreviations. For example: 1366x768 is given the name HD (High Definition) and 1920x1080 for FULL HD. The latter has a very high resolution and displays an image that is twice the amount of pixels as compared to an HD screen.

This kind of measurement denotes the pixels or dots horizontally times by the pixels or dots vertically. For example 1366x768 means 768 horizontal lines each containing 1366 pixels and giving a total pixel count of 1049088 which is just over a million pixels to make up the entire image.

Another way is to go through laptop manual. It is always mentioned in the specifications section. You can also go to manufacturer’s website and search laptop model and its specification.

Retina Display is used by Apple for screens having a higher pixel density. For the third generation MacBook Pro (15”), the resolution is 2880X1800 which makes the total pixel count of 5,184,000 and for the MacBook Pro (13”), the resolution is 2560X1600 making the pixel count to 4,096,000. With such high resolution, the quality of display is very high.

Leading laptop manufacturers are launching laptops with ultra HD screen which has a very high resolution of 3840x2160p which is four times higher than that of the standard Full HD screen.

Ans: Laptop screen display upgrade or downgrade is generally not recommended. The reason being the resulting distorted display. Problems like improper working of video cards may occur. Video cards are used for image processing and get overloaded when connected to a higher resolution LCD screen because higher processing power requirement. So improper working of video card will directly affect the image display. But you can always replace an old laptop screen with a new one if both of them have same resolution and other specification.

Ans:If you want to buy new screen with screen part number, you will need exact part number of the screen. Sometimes it is tricky to find screen part number. Usually screen part number is written either on back side of screen or inverter. The most important information is the manufacturer’s code and the screen size. Fortunately, the information for both can be found in one place, on the back side of the screen itself. For example let’s say the code you find on the back of your laptop screen is LP156WH2(TL)(A1).

This translates into having a LG Philips 15.6 inch screen. The “LP” is the code for LG Philips and the “156” is the code for the screen size of 15.6 inches. You’ll often see this code next to or above the UPS bar code for the screen.

A list of LCD screen manufacturers along with their abbreviations is given below. The first few letters of the model number correspond to the manufacturers.

Ans: We are a UK VAT registered company and we do provide a VAT invoice with every purchase. This will be emailed to you when the item has been dispatched along with the tracking number.

Ans:Dead/ defective pixels are the pixels that do not perform properly. Few dead pixels do not make a screen completely useless because the pixel count goes in millions. Many standards have been set from time to time which provide the guidelines for the permissible defective pixel limit such as ISO 13406-2, ISO 9241-302, ISO 92341-303 etc. If 4 or 5 pixels are defected or dead, screen manufacturers consider it acceptable as it does not make screen poor quality or affect screen quality

We sell brand new screens and normally the error ratio is less than 0.1%. "Screen display up to 2 fixed pixels is within industry standards and is therefore considered acceptable display” However if there is any issue, please email us and we will try to resolve it.

Different laptop manufacturers have different dead-pixel policies. Here are the links to some leading laptop manufacturer’s dead pixel policy which will give you a better understanding:

Most laptop LVDS displays have at least kinda-weird connectors. I don"t support Panelook, and actively avoid that site -- it"s got a paywall between users and documentation, and I refuse to support such a thing in absolutely all cases.

It"s a matter of digital safety, as far as I"m concerned -- websites almost never audit their ad providers, and website-level ad providers, in turn, almost never audit their content sources (the people / organizations / etc providing the actual ads) -- so it"s *extremely* easy for a rogue actor to insert something nasty into the mix. Many such "nasties" need only for the ad to load on the page for the payload to activate, and now that there"s at least one active Linux virus going around, I"m taking even fewer chances than usual.

Datasheets are easy to find... you just have to know what you"re doing. (I know of at least one well-traveled electronics YouTuber who doesn"t, and moans about it frequently without realizing that they just don"t know the trick.)

...you will get a number of links of various sorts. Look *specifically* for links that have a little [PDF] icon next to them, i.e., the acronym "PDF" in a (very!) thin outline of a box. If the entire first page doesn"t have anything for you, look for results from eg datasheetspdf.com datasheet4u.com datasheetarchive.com etc. Datasheet Archive (the last one) is actually my favorite. *Absolutely avoid* Panelook if you"re at all like me, but also twscreen.com hkinventory.com etc -- those are sales sites and you"ll never ever *ever* get a PDF out of them so long as you live. Also avoid lcds-center.com lcds-display.com lcds-source.com etc -- these are particularly egregious, because they"ll return [PDF] results, but the PDFs are generated when you click the link and are in fact sales info only -- nothing actually useful in the sense of a technical document, and nothing that gives you even the faintest glimmer of hope of a way to get one. Screw "em.

Obviously, if something asks you to sign up for something to view the datasheet, Admiral Ackbar"s famous quote should be ringing in your mental ears and you should get the freaking heck out of there five minutes ago.

Also remember that many datasheet websites -- particularly Datasheet Catalog -- will return results that lead to a PDF datasheet, but it"s not immediately obvious as such because they don"t get the [PDF] tag, because it"s not a direct link straight to the content.

As for Datasheet Archive, it"s... a little confusing if you don"t know what you"re doing. Scroll down till you see the "Datasheets Context Search" -- you"ll have to wade through "Top Results" "Search Stock" and "Datasheet" results -- the last of which is extremely likely, unfortunately, to be nothing but false positives. Find a listing in the Context Search, as close to the top as you can manage, that looks like it has relevant text in the little sampler blurb they give you. Click the capsule-shaped "PDF" button on the right, then click the red "datasheet" tab in the box that pops up. Click "View Datasheets". A new tab wll open; switch over to it. On that page, if you click "Download Datasheet", your browser"s inbuilt PDF viewer will take it from here ;) Otherwise, you can see it in the little window they give you. Do what you need to do ;)

When you connect your Surface to a TV or monitor, your Surface tries to set the best resolution based on the connector and the resolution of your TV or monitor.

The resolution and refresh rate supported for the external display depends on how many displays are connected and whether the display on your Surface is on or off. It also depends on which processor you have.

When connecting through Surface Dock there’s a maximum screen refresh or resolution possible, even if some Surface model capabilities exceed this. The following table specifies the max refresh rate and screen resolution for Surface devices that are using either one or two external displays.

When you use two external displays, you may be able to achieve a higher refresh or screen resolution on one display by lowering the refresh or screen resolution used on the other.

and check for the part / model number on the label on the back. If you"re not confident doing this there are often other ways to find out what you need.

While not all laptop models are so easy to identify, in most cases the best source of information is just a Google search away. You wil often be able to find
