Hi ULStudent:CLODAGH.O'CALLAGHAN,
Welcome to Microsoft Community. I'm sorry to hear that you're experiencing issues with your Surface Go 2 display. Can you please provide more details about the "weird cast" you're seeing? Is it a discoloration, a flickering, or something else? UEFI settings aren't in Windows, so display issues in UEFI suggest a problem with hardware, rather than with a Windows driver. Here's how to check if the screen issues only happen when you're using Windows:
- Turn off your Surface and wait 10 seconds.
- Press and hold the volume up button on your Surface, and at the same time, press and release the power button . The logo screen will appear.
- Continue to hold the volume up button . Release the button when the UEFI screen appears.
- View the screen and see if the problem is still present. If the screen is working correctly within UEFI, the problem is likely with the software installed on the Surface. Proceed with the reinstall the display adapter and OEM panel driver section.
Reinstall the display adapter and OEM panel driver section.
- Select and hold (or right-click) Start and select Device Manager.
- Expand the Monitor section, select and hold (or right-click) the Surface panel driver(s), then select Uninstall device. Read the warning, then select Uninstall and restart your PC.
- Expand the Display adapters section, select and hold (or right-click) the listed adapter (Intel and NVIDIA graphics drivers), then select Uninstall device. Confirm by selecting Attempt to remove the driver for this device, then select Uninstall and restart your PC.
- After your PC restarts, select Start > Settings .
- From Settings , select Windows Update > Check for updates, and install any available updates.
There's one last step you can take. If these steps don't resolve the problem, service and support options may be available to assist you.
If you decide to send it in, go to Device service and repair and sign in with your Microsoft account. If your device is already registered, select it and follow the instructions. If your device isn't listed, select Don't see your device? to register it, then follow the instructions to get service.
Through this process, you’ll find out if your Surface is in or out of warranty and how much it’ll cost, if applicable. Depending on the product, the service offered may be a repair or a refurbished replacement. Once an order is created, you’ll get a shipping address so you can send in your device. Your SincerelyHahn.
