How to Find Your Laptop Screen Model Number (Step-by-Step Guide)
To find the model number of your laptop screen, follow these steps:
Check the Laptop Manual:
Consult the user manual that came with your laptop. It often contains information about the specific model and components.
Inspect the Laptop Bezel:
Examine the front bezel of your laptop screen. Sometimes, manufacturers print the model number directly on the bezel itself.
Look on the Back of the Laptop:
Turn your laptop over and inspect the bottom. There may be a sticker or label containing information about the laptop model, which may include details about the screen.
Check System Information:
On Windows: Press Win + R to open the Run dialog, type msinfo32, and press Enter. Look for “System Model” under the System Information tab.
On macOS: Click the Apple logo in the top-left corner, select “About This Mac,” and find the model information.
Visit the Manufacturer’s Website:
Go to the official website of your laptop’s manufacturer. Look for a support or product section where you can enter your laptop’s serial number or browse through available models.
Inspect the Screen Itself:
Carefully remove the bezel around the screen and check for any labels, stickers, or markings directly on the back of the screen.
Use System Diagnostics:
Some laptops have built-in diagnostics tools that provide detailed information about the system components. Check your laptop’s manual for instructions on accessing diagnostic tools.
Check the Original Packaging:
If you still have the original packaging for your laptop, the model number is often printed on the box.
On the back side of the screen you can see one or several labels with numbers. 99% of the screens on the market today have manufacturer’s code and screen size included in the model number. For example, screen model number B101AW06 means that the screen is manufactured by AU Optronics and this screen’s diagonal size is 10.1″.
Below is a list of most common laptop LCD screen manufacturers with their abbreviations:
AU Optronics – B BOE Hydis – HB Chi Mei / Innolux – N Chunghwa – CLAA HannStar – HSD IVO – M LG Display – LP Samsung – LTN Sharp – LQ or LM Toshiba – LTM or LTD
Typical LCDs are mounted with 2, 3 or 4 screws on the left and the right side of the LCD.
Some LCDs are mounted via built-in brackets.
Important! All product images match the exact bracket configuration of a replacement screen that will be sent to you. LCD brackets are built onto the LCD module – don’t confuse them with the LCD mounting brackets that are part of a laptop and should be unscrewed from the LCD and reused during the reinstallation process.
Examples of LCD mountings:
Screen connector
There are several different types of video connectors used in laptops screens. For the most part the connectors are not interchangeable. Here are the most common types of video connectors that are in use today:
30-pin eDP – the main modern connector. It is used on screens with resolutions up to 1920 x 1080. If your laptop was manufactured after 2014 and features screen resolution up to 1080p it is likely using this type of connector.
40-pin Narrow Connector 40-pin touch interface and eDP video connector used on some Lenovo laptops starting from 2020.
40-pin same physical connector standard but 3 different and incompatible signals
40-pin eDP Touch – used on newer laptops after 2015, the additional pins over the 30-pin eDP connector are needed for a built-in (on-cell) touchscreen functionality.
40-pin eDP QHD+ – used on newer laptops after 2015, the additional pins over the 30-pin eDP connector are needed for higher resolution options such as QHD (2560 x 1440) and even higher (4 channel eDP).
“40-pin eDP Touch” LCDs are not interchangeable with “40-pin eDP QHD+” screens. Even though the connectors are the same, plugging a “40-pin eDP Touch” LCD in-place of a “40-pin eDP QHD+” screen will not provide the touch functionality, and vice-versa, plugging a QHD screen in place of a 40-pin touchscreen will not provide higher resolution.
40-pin LVDS (old)
Used on most LED back-lit laptops prior to 2014. It was the most common standard at the time and allowed resolutions up to 1920 x 1080p. Screens fitted with 40-pin LVDS connector are not interchangeable with screens fitted with 40-pin eDP because of the two different signalling technologies, even-though the connectors follow identical physical standards.
Other
120Hz+ LVDS (gaming) screens used a 50-pin connector CCFL screens (obsolete) used 20-pin LVDS and 30-pin LVDS connectors. MacBooks use their own proprietary LVDS and eDP connector types.
How to find screen resolution
It is important to confirm the screen resolution before submitting an order: the same laptop model can come with different display resolutions.
If a laptop you are ordering a screen for works – turn it on and:
– for Windows XP, Windows 2000, Windows ME, Windows 98: Right-Click on Desktop -> Properties -> then in Display Properties navigate to Settings – for Windows 10 and Windows 7 & Vista: Right-Click on Desktop -> Personalize -> Graphics Options
If a laptop you ordering a screen for is not functional:
