Hi @Faizal Rm,
Welcome to Microsoft Q&A forum.
Based on your issue regarding the cursor flickering on your Surface Book 2 (15-inch) when using the 3000x2000 resolution, I understand that disabling the Intel UHD Graphics 620 adapter temporarily resolves the symptom, but this limits the device's overall display performance.
This behavior is typically associated with a conflict between the integrated graphics power management settings and the high-resolution panel. To resolve this, I recommend the following troubleshooting steps:
Step 1: Disable panel self-refresh
- Open the Intel Graphics Command Center (available via the Start menu or Microsoft Store).
- Navigate to System > Power.
- Locate Panel Self Refresh and toggle the setting to Off for both On Battery and Plugged In modes.
- Restart the device to apply the changes.
Step 2: Refresh rate verification
Ensure the display refresh rate is synchronized correctly with the Windows desktop manager.
- Go to Settings > System > Display > Advanced display.
- Under Choose a refresh rate, ensure it is set to exactly 60.00 Hz. If it is currently set to a decimal value (e.g., 59.97 Hz), please switch it to 60.00 Hz.
Step 3: Reinstall surface-specific display drivers
If the flickering persists, the current driver may be corrupted. Reinstalling the official Surface firmware driver is recommended.
- Right-click the Start button and select Device Manager.
- Expand Display adapters, right-click Intel(R) UHD Graphics 620, and select Uninstall device.
- Ensure the box for Attempt to remove the driver for this device is checked, then click Uninstall.
- Restart the Surface. Windows will automatically reinstall the calibrated driver version included in the Surface firmware.
Kindly update the outcome of these steps so I can further check if the problem persists.
