Hi Andy Pratt,
In addition to the helpful suggestions already provided in the AI Answer, I'd like to suggest a few more checks that may help narrow down the cause of the green tint.
One useful test is to start the device in Safe Mode and then check the camera. Safe Mode loads Windows with only the essential drivers and services, which can help determine whether a background application or software conflict is contributing to the issue. To enter Safe Mode, go to Settings > System > Recovery, then select Restart now next to Advanced startup. After the device restarts, choose Troubleshoot > Advanced options > Startup Settings > Restart. When the Startup Settings screen appears, press 5 or F5 to start Safe Mode with networking. Once you're signed in, open the Camera app and see if the green tint is still present. If the camera looks normal in Safe Mode, that may indicate that a third-party application or background software is affecting the camera. If the green tint remains, the issue is more likely related to the camera driver, firmware or hardware itself.
If your Surface has both front and rear cameras, please try testing each camera separately in the Camera app. This can help determine whether the problem affects only one camera or all camera hardware on the device. If only one camera shows the green tint, that may point to an issue with that specific camera module.
You may also want to temporarily disable the Windows Hello IR camera and test again. Open Device Manager, expand Cameras, locate the IR Camera or Windows Hello camera, right-click it and select Disable device. Restart the Surface and check whether the camera image improves. This can help rule out a potential conflict between camera components.
Another worthwhile step is to run the Surface Diagnostic Toolkit or the diagnostics available through the Surface app. These tools include camera tests that can help identify image distortion or other camera-related issues. While running the tests, check whether the same green tint appears in the diagnostic preview.
I'd also recommend performing a force restart of the Surface. First, shut down the device completely. Then press and hold the Power button for about 20 seconds. Continue holding the button even if the Surface logo appears and release it only after the logo appears a second time. Once Windows starts again, test the camera to see if the image quality has improved. Microsoft recommends this step when troubleshooting persistent Surface camera issues.
If the green tint remains visible in the Camera app, appears across multiple applications and continues even in Safe Mode after these checks, the issue may indicate a hardware problem with the camera module. In that case, it may be worth contacting Surface Support to discuss available repair or service options.
Please let me know your exact Surface model and whether the issue affects the front camera, rear camera or both cameras and I'll be happy to continue assisting.
