2. Identify the laptop model:

  • Check the Bottom of the Laptop:

    • Look for a sticker or label on the bottom of your laptop. The model number is often printed there, along with other information.
  • Check the Laptop’s Documentation:

    • Consult the user manual or any documentation that came with your laptop. The model number is typically mentioned in these materials.
  • Use 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.

6. Remove the screws:

  • Locate and remove the screws securing the screen to the laptop. These are typically found along the sides of the screen or under rubber covers.
  • Keep track of the screws and their placements as they may differ in size.

7. Disconnect the screen:

  • Once the screws are removed, gently tilt the screen forward.
  • Locate the video cable connecting the screen to the laptop. Carefully disconnect it by releasing any clips or connectors.

8. Install the new screen:

  • Connect the video cable to the new screen, ensuring it is secure.
  • Align the new screen in place and reattach the screws.
  • Snap the bezel back into position.

9. Test the new screen:

  • Power on the laptop and check if the new screen displays properly.
  • If there are any issues, double-check the cable connections and the seating of the screen.

10. Reassemble the laptop:

  • Once you confirm the new screen is working, reassemble the laptop in the reverse order.
  • Tighten all screws securely, but be careful not to overtighten and damage the threads.

11. Clean the screen:

  • Use a soft, lint-free cloth to clean the new screen.
  • Avoid using harsh chemicals that may damage the display.

Remember to take your time and be patient during the process. If you’re unsure at any step, consult your laptop’s user manual or seek professional assistance.

LCD Mounting and LCD brackets

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-lcd-screen-connector-mylaptospcreen.com

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-laptop-screen-
40-pin Narrow Connector
40-pin touch interface and eDP video connector used on some Lenovo laptops starting from 2020.

Narrow 40pin – pitch 0.4mm (found in Lenovo OnCell touch)
Regular 40pin – pitch 0.5mm
40-pin-connector

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.
