Hi Goncalo1500,
Thank you for reaching out to Microsoft Q&A forum and taking the time to explain the display issue in detail. I understand how frustrating it can be when your main laptop screen is not being detected correctly and settings like refresh rate don’t behave as expected.
From what you’ve described, this behavior does point to an issue with the laptop’s integrated graphics not being recognized correctly. On most laptops, the built‑in screen is handled by the integrated graphics, while external monitors are typically driven directly by the NVIDIA GTX 1650. If the integrated graphics driver is missing, disabled, or not functioning properly, Windows can have difficulty identifying the internal display. This can result in symptoms like an unknown refresh rate, incorrect screen names, or the laptop screen going blank when the external monitor is disconnected.
I can see that the Q&A assistant has already shared several general troubleshooting steps with you. Since the issue is still persisting, here are a few additional things we can try next that focus more specifically on the internal display and graphics behavior:
Step 1: Verify integrated graphics is enabled at firmware level
- Power off the laptop completely.
- Power it back on and immediately enter BIOS / UEFI (commonly F2, DEL, ESC, or F10, depending on the model).
- Navigate to the Graphics, Advanced, or Chipset section.
- Confirm that Integrated Graphics, iGPU, Hybrid Graphics, Switchable Graphics, or Optimus is Enabled.
- Ensure it is not set to “Discrete only.”
- Save changes and exit.
Step 2: Restore proper GPU ownership of the internal display
Because the internal panel is wired to the integrated GPU, it must be detected and initialized first.
- Remove all display drivers so Windows resets display routing.
- Restart the system.
- Install the integrated graphics driver first, using the laptop manufacturer’s official support page (not Windows Update).
- Restart the system again.
- Install the NVIDIA GTX 1650 driver.
- Restart once more to complete initialization.
This order is essential since without a working integrated graphics driver, Windows cannot assign the internal screen correctly.
Step 3: Confirm internal screen is controlled by the integrated GPU
After reboot:
-Open Task Manager > Performance
- You should see two GPUs listed.
- The integrated GPU should show activity when the laptop screen is active.
-Open Device Manager > Display adapters
- Both GPUs should appear without warning icons.
Step 4: Reassign the correct main display
Once the integrated GPU is active:
- Open Display Settings.
- Use Identify to confirm which screen is the laptop panel.
- Select the internal screen and set it as the Main display.
- Open Advanced display settings to confirm that refresh rate and properties are now available for the internal screen.
If the laptop screen still remains blank or incorrectly identified after completing these steps, it may indicate a firmware‑level configuration issue or a failed integrated GPU initialization.
Please keep me posted on how it goes. I’m here if you need further assistance.
