The pattern points to a Windows-side display initialization problem rather than a basic panel failure, because the UEFI screen is stable and the failure starts when Windows takes over the display path. In the provided guidance, black screens with a cursor or after startup are commonly tied to a stalled Windows process, display output misconfiguration, or a driver issue. Screen flickering is also described as usually caused by a display driver issue or an incompatible app.
Most relevant checks:
- Reset the graphics driver when the screen goes black:
- Press Windows + Ctrl + Shift + B.
- A beep or screen flicker indicates the graphics driver reset was triggered.
- Check whether Windows is sending output to the wrong display mode:
- Press Windows + P.
- Then tap P again and press Enter to cycle display modes.
- This is specifically recommended for blank-screen cases caused by display output misconfiguration.
- Try the security screen path:
- Press Ctrl + Alt + Del.
- If the security screen appears, open Task Manager.
- From there, try restarting Windows Explorer.
- If the issue presents as flicker or distortion, use Task Manager to help isolate the cause:
- Press Ctrl + Alt + Delete to open Task Manager. If Task Manager does not appear, press Ctrl + Shift + Esc.
- If Task Manager flickers too, the guidance says a display driver is probably causing the problem.
- If Task Manager does not flicker while the rest of the screen does, an incompatible app is probably causing the problem.
- If the display does not recover, force a restart:
- On Surface models including Surface Pro 7 generation devices covered by the Surface restart guidance, press and hold the power button until the device shuts down and restarts and the Windows logo appears, about 20 seconds.
- This matches the behavior already observed where a full power cycle often restores the display.
What the available guidance supports as the likely explanation:
- Display driver issue: supported by the flicker troubleshooting guidance.
- Display output misconfiguration during Windows startup: supported by the blank-screen guidance recommending Windows + P cycling.
- A stalled Windows process after login/startup: supported by the blank-screen guidance recommending Ctrl + Alt + Del and restarting Windows Explorer.
What is not established in the provided material:
- A confirmed root cause in WDDM/DXGKRNL, eDP panel initialization, ACPI, or a specific defect in Intel driver 31.0.101.2130 is not provided.
- The abnormal resolution observation is consistent with Windows not initializing the display path normally, but no deeper kernel or firmware-level explanation is given in the available material.
Because UEFI is normal and the failure begins when Windows takes over, the supported conclusion is: the issue is most consistent with Windows display-driver or display-mode initialization during startup, restart, or resume, not with a basic always-failed screen panel.
