Where Can I Find Laptop Screen Model Number? | Quick Locate Tips

Guide / By

The laptop screen model number sits on the panel label or can be read from EDID data using built-in tools on Windows, macOS, or Linux.

If you’re shopping for a replacement display, checking compatibility, or cross-referencing a vendor’s listing, you need the exact panel code. This guide shows fast, low-risk ways to read that code without guesswork, plus the safe way to confirm it from the label on the panel itself.

Find Your Laptop Panel Code: Fast Methods

There are three reliable places to look:

  • Operating system tools that read the EDID the display broadcasts.
  • Vendor manuals and service documents that list approved parts.
  • The physical label on the back of the LCD once the bezel is off.

What The Screen Model Number Looks Like

The code usually combines the maker prefix and a short spec string. You’ll see formats like LP156WF6-SPB1 (LG Display), B140HAN01.2 (AU Optronics/Innolux), or N156HCE-EA1 (BOE). Retail names such as “FHD 144 Hz” aren’t the model; those are features. The printed label on the panel and the EDID both carry the true identifier.

Read The Panel Code In Windows (No Disassembly)

Windows exposes display identity through WMI/EDID. The simplest path is Device Manager, but PowerShell gives cleaner results for built-in laptop panels.

Device Manager Path

  1. Right-click Start → Device Manager.
  2. Expand Monitors → double-click your active display.
  3. Open the Details tab → choose Hardware Ids from the drop-down.
  4. Copy the string that starts with MONITOR\. The short code in that string maps to the panel model via EDID.

Want the human-readable model in one line? Use PowerShell to decode the EDID fields.

PowerShell One-Liner (Copy And Paste)

Get-CimInstance -Namespace root\wmi -ClassName WmiMonitorID |
  ForEach-Object {
    $m = ($_.UserFriendlyName | Where-Object { $_ -ne 0 } | ForEach-Object {[char]$_}) -join ''
    $maker = ($_.ManufacturerName | Where-Object { $_ -ne 0 } | ForEach-Object {[char]$_}) -join ''
    $serial = ($_.SerialNumberID | Where-Object { $_ -ne 0 } | ForEach-Object {[char]$_}) -join ''
    [PSCustomObject]@{ Manufacturer = $maker; Model = $m; Serial = $serial }
  }

This pulls the “UserFriendlyName” from EDID and prints a neat Manufacturer / Model / Serial card for each active display. If the laptop lid panel is active, you’ll see its code here. Some firmware hides serials; that’s fine—model is the field you need.

Why PowerShell Beats Old WMIC For Panels

The legacy wmic desktopmonitor view often shows blanks on integrated displays. The CIM/WMI classes that read EDID fields return better data for modern laptops.

Find It On A MacBook Without Tools

macOS lists panel identity in the system report. You don’t need any apps.

  1. Open Apple menu → System Settings → General → About → System Report…
  2. Go to Graphics/Displays.
  3. Under the built-in display, copy the Panel ID / Display model details. You’ll see maker and a panel code or an identifier that maps to the panel family.

For Apple external displays, the same panel identity and serial appear in the system report when connected.

Read The Code On Linux

Linux exposes the EDID under /sys/class/drm/ and through standard tools.

EDID Via Sysfs + edid-decode

  1. Identify your embedded panel connector (often eDP-1 or eDP-1-0): ls /sys/class/drm/ | grep eDP
  2. Dump and decode EDID:
sudo cat /sys/class/drm/card0-eDP-1/edid | edid-decode

In the decoded output, look for the “Display Product Name” or “Model” line. That’s the panel code you want.

EDID Via read-edid Package

sudo apt install read-edid -y
sudo get-edid | parse-edid

Many distros package read-edid. If your distro uses a different manager, install the same tools from its repo, then run the pipeline above.

When The OS Doesn’t Show It

A few laptops mask the model field or expose only a short code. In those cases, use the vendor’s service manual or pull the bezel to read the sticker on the back of the panel.

Use The Service Manual

Most OEM manuals list approved LCD assemblies by part number. That list maps to the exact panel families that fit your chassis. Search for your laptop’s maintenance or service guide; you’ll find a parts table with LCD entries such as “FHD IPS 60 Hz” followed by a part code. Cross-reference that part code when ordering.

Read The Physical Label (Last Resort)

If you’re comfortable removing the bezel, you can confirm the code directly from the sticker. Power off, disconnect AC, and if the model allows, pop the bezel with a plastic spudger—no metal pry tools near the glass. Tilt the panel forward, support it with one hand, and read the white barcode label on the rear. That line is the model. Take a photo so you don’t have to open it again.

How To Verify Compatibility Before You Order

Matching the model code is the safest route, but checking these specs avoids surprises:

  • Size and mount points (e.g., 13.3″ vs 15.6″; tabs align).
  • Resolution and refresh (FHD/QHD/4K; 60 Hz/120 Hz/144 Hz).
  • Connector type (eDP 30-pin vs 40-pin; position on the panel).
  • Backlight type (modern panels are LED; older CCFL need inverters).
  • Finish and gamut (matte/glossy; sRGB vs wide-gamut).

Quick Troubleshooting If The Code Won’t Appear

  • Toggle the panel active: close external monitors so the internal display becomes primary, then rerun the command.
  • Update graphics drivers and reboot, then read EDID again.
  • Try a second method: if Device Manager is vague, use the PowerShell command; on Linux, use edid-decode.
  • Use the manual or label when firmware hides ID fields.

Copy-Ready Commands

Windows: Clean Panel Model Readout

# Run PowerShell as Administrator
Get-CimInstance -Namespace root\wmi -ClassName WmiMonitorID |
  ForEach-Object {
    $name = ($_.UserFriendlyName | Where-Object { $_ -ne 0 } | ForEach-Object {[char]$_}) -join ''
    $mfg  = ($_.ManufacturerName | Where-Object { $_ -ne 0 } | ForEach-Object {[char]$_}) -join ''
    "Model: $name  |  Maker: $mfg"
  }

Linux: Find EDID Connector And Decode

ls /sys/class/drm/ | grep -E "eDP|LVDS"
sudo cat /sys/class/drm/card0-eDP-1/edid | edid-decode | sed -n '1,80p'

macOS: System Report Path

Apple menu → System Settings → General → About → System Report… → Graphics/Displays

Real-World Panel Code Examples

These examples show how the label maps to specs you’ll see in listings:

  • LP156WF6-SPB1 → 15.6″, 1920×1080, IPS family; vendor is LG Display.
  • B140HAN01.2 → 14.0″, 1920×1080, common 30-pin eDP; vendor is AUO/Innolux.
  • N156HCE-EA1 → 15.6″, 1920×1080 IPS, 30-pin eDP; vendor is BOE.

Small suffix changes mark sub-revisions. A different final two letters can signal a cable angle or backlight tweak even when size and resolution match. When a seller proposes an “equivalent,” ask for the full code they’ll ship.

OEM Docs Help Too

Brand manuals and parts portals often list every approved LCD assembly for a chassis. If your OS method returns only a short ID, search that manual to see the exact replacement codes. Matching an approved part keeps webcam cables, hinges, and brackets aligned.

Common Pitfalls To Avoid

  • Ordering by laptop model only: many variants share a shell but use different panels and connectors.
  • Ignoring connector position: a left-side vs right-side ribbon can block installation.
  • Assuming refresh rate: a 144 Hz listing won’t help if the board and cable only support 60 Hz.
  • Skipping photos: always keep a clear shot of the label and your old connector before you close the lid.

Quick Reference Table

Where To Check What You’ll See Best Use
Windows PowerShell (WmiMonitorID) Maker and model from EDID Fast, no disassembly
macOS System Report Panel ID/model for built-in or Apple external Built-in display confirmation
Linux edid-decode Full EDID with product name Detailed technical readout
Service manual Approved LCD part numbers Cross-checking equivalents
Panel label Exact sticker code on back Final confirmation before purchase

Safe Handling If You Open The Lid

  • Shut down the laptop and unplug the charger.
  • Press and hold the power button for 10–15 seconds to drain residual power.
  • Use a plastic pick to lift the bezel; keep pressure gentle and even.
  • Lay the panel face-down on a soft cloth while reading the label; don’t twist the ribbon.
  • Re-seat the connector firmly until the latch clicks before reassembling.

When To Ask The Seller For Proof

If a listing claims a match but shows a different suffix, request a photo of the actual label. Ask them to confirm connector pin count, position, and refresh. A reputable shop will share a label shot and the exact panel code they’ll ship.

Helpful Official Pages

On Windows, the WMI class that carries the model is documented publicly; if your script prints blanks, the firmware may hide fields and you’ll need the label or manual. On a Mac, the display section in the system report lists connected panel details without extra tools.

Learn the Windows WMI fields used for monitor identity on the WmiMonitorID documentation. For macOS, the path to the display model is covered in Apple’s guide to System Information.
