How to Identify the Internal LCD Panel Model in an MSI GS76 Stealth
Replacing a laptop screen is a high-stakes repair. For the MSI GS76 Stealth 11UH-078, which features a premium 17.3-inch 4K 120Hz panel, simply knowing the laptop model is insufficient. Manufacturers often source "IPS-level" panels from multiple vendors like AU Optronics (AUO), BOE, or Innolux during a single production run. Installing a panel with an incompatible 40-pin eDP pinout or different bracket positioning can lead to a blown backlight fuse or a "no-post" state. This guide provides a non-invasive methodology to extract the Hardware ID and manufacturer string using software tools, ensuring you order the exact replacement part without prying off the delicate bezel.

Purpose
The primary purpose of this tutorial is to find the Manufacturer Part Number (e.g., B173ZAN06.1 or MNG007DA1-1) that is flashed onto the display's EDID (Extended Display Identification Data) chip. Since the GS76 Stealth uses a thin-bezel design with adhesive strips, physical inspection often results in cracked plastic or damaged LCD layers. By reading the EDID via the Windows OS or third-party diagnostic utilities, we can retrieve the panel's specifications—color gamut, refresh rate, and connector type—with 99% accuracy.
Use Case
This identification workflow is required when:
- LCD Damage: Your screen has "dead zones," vertical lines, or backlight bleed and requires a 1:1 replacement.
- Display Upgrading: You are checking if your current 40-pin eDP cable supports a higher brightness (nits) or better color accuracy (100% AdobeRGB) panel.
- Color Calibration: You need to find the correct ICC profile for your specific panel manufacturer to improve photo/video editing accuracy.
- Resale Verification: Confirming the panel's specs (like the 120Hz refresh rate) for a potential buyer.
Step by Step
Method 1: Windows Device Manager (No Software Required)
This is the fastest way to get the generic Hardware ID, which often encodes the manufacturer and model series.
- Right-click the Start button and select Device Manager.
- Expand the Monitors section.
- Right-click Generic PnP Monitor (or "Integrated Display") and select Properties.
- Go to the Details tab and change the property dropdown to Hardware IDs.
- Look for a string like
MONITOR\AUOA988. The characters after the slash are the encoded model.
Method 2: HWiNFO64 (Highly Recommended)
For the MSI GS76, standard Windows IDs can sometimes be generic. HWiNFO64 provides the "Monitor Name" and "Monitor Model" directly from the firmware.
- Download and run the Portable version of HWiNFO64.
- In the main tree view on the left, expand Monitor and click on the internal panel entry.
- In the right pane, look for Monitor Name (e.g.,
AUO B173ZAN03.3) and Monitor Name (Manuf). - Note the EDID Revision and Video Interface (usually eDP) for compatibility checks.
Method 3: PanelLook Lookup
Once you have the model string (e.g., B173ZAN), you must verify the physical specs:
- Visit PanelLook.com.
- Enter the model string into the search bar.
- Verify the Interface Type (40 pins), Signal Pitch (0.4mm or 0.5mm), and Shape Style (Slim/Flat) to ensure the replacement fits the GS76 chassis.
Best Results
To ensure a successful replacement, cross-reference your findings with this common MSI GS76 hardware table:
| Panel Component | Standard 4K 120Hz Spec | Check Compatibility For: |
|---|---|---|
| Connector | 40-pin eDP | Pin pitch (0.4mm is standard for 4K) |
| Mounting | No Brackets (Adhesive) | Verify if replacement has "tabs" (ears) |
| Backlight | WLED / Mini-LED | Ensure voltage matches (usually 3.3V) |
| Width | Narrow/Small Bezel | Compare physical dimensions (mm) |
FAQ
What if my screen is black? Can I still find the model?
If the internal screen is completely dead, software methods will only work if the EDID chip is still readable by the GPU. If not, you must use an external monitor to run the tools, but they may only show the external display's info. In this case, searching your Serial Number (S/N) on the MSI Support site or checking your original invoice for the 11UH-078 SKU is the best alternative.
Why does HWiNFO show a different model than the box?
Laptop manufacturers like MSI use "IPS-Level" to describe panels that meet a certain spec. They may use a Sharp panel in one batch and an AUO in the next. The software ID is the actual hardware currently inside your specific unit.
Is "40-pin" enough information to buy a screen?
No. 40-pin connectors come in different physical widths (e.g., 21mm vs 25mm). For 4K 120Hz displays, the pin pitch is often narrower (0.4mm) than standard 1080p 144Hz screens (0.5mm).
Disclaimer
Identifying the model via software is highly reliable for electronic compatibility, but it does not account for physical variations like cable length or adhesive placement. Always verify the "Slim" or "Non-Slim" designation on the seller's listing. This guide is current as of early 2026. Performing a screen replacement may void your MSI warranty if the factory seal is broken.
