How to Find the Correct Replacement Laptop Screen (Full Compatibility Guide)

1. Check the part number on your original screen

The most reliable method is to remove your screen and look at the label on the back.
It will show a code like:

  • LP156WF6-SPB1

  • NV156FHM-N4G

  • B140HAN04.0

This single code tells you:

  • Screen size (e.g., 14.0", 15.6")

  • Resolution (HD, FHD, QHD, 4K)

  • Panel type (IPS / TN)

  • Connector type (30-pin or 40-pin eDP)

  • Refresh rate and brightness

  • Mounting style & connector position

Matching the part number guarantees compatibility.

2. If you can’t check the part number…

You can still find the right screen using:

  • Your laptop model number

  • Your current screen’s size and resolution

  • The connector type (30-pin or 40-pin)

However, the same laptop model often comes with multiple screen types, so this method requires verification.

3. Avoid guessing—many models have multiple screen options

Even identical laptop models can use different displays:

  • HD / FHD / QHD / 4K

  • IPS vs TN

  • Touch vs non-touch

  • 30-pin vs 40-pin

  • 1-lane vs 2-lane eDP

That’s why confirming the part number is the safest approach.
