Windows 11 KB5077181 Sleep Wake Graphics Crash and HDMI Detection Failure

What is the KB5077181 Sleep Wake Graphics Crash?

After installing the Windows 11 February 2026 update KB5077181 (OS builds 26100.7840 and 26200.7840), some users experience a black screen, system freeze, or BSOD when waking from sleep. External monitors connected via HDMI may fail to be detected entirely after resume. The root cause is a conflict between the update's changes to Secure Launch and power management transitions, and GPU drivers — particularly NVIDIA's nvlddmkm.sys and the DirectX Graphics Memory Manager dxgmms2.sys.

Event Viewer shows Event ID 4101 ("Display driver nvlddmkm stopped responding and has successfully recovered"), Event ID 41 Kernel-Power (unexpected reboot), or a BSOD with bug check 0x139 KERNEL_SECURITY_CHECK_FAILURE pointing to dxgmms2.sys. NVIDIA driver 582.28 and GPUs including RTX 3050, RTX 4090, and GeForce MX130 have been confirmed affected. AMD RX 6600 users also report HDMI detection failures.

When does it occur?

• When waking from S3 sleep with an external HDMI monitor connected
• After the system enters hybrid sleep (S3 + hibernation combined)
• When the display turns off via power settings before the system sleeps
• On laptops with NVIDIA Optimus switching between integrated and discrete GPUs
• After a Windows Fast Startup resume with an external display

Common causes

• KB5077181 reintroduced conflicts with legacy S3 sleep states and GPU driver power transitions
• Modern Standby (S0 Low Power Idle) conflicting with GPU driver state restoration
• PCI Express Link State Power Management disrupting the GPU link during sleep
• Hybrid sleep combining S3 and hibernation causing GPU state mismatch on wake
• TDR (Timeout Detection and Recovery) timeout killing the GPU driver during slow wake transitions
• HDMI EDID handshake failure during display reinitialization after power state change
• Outdated or incompatible NVIDIA/AMD display drivers

Step-by-step fixes

1. Disable Modern Standby via registry — Open Command Prompt as Administrator and run: reg add "HKLM\System\CurrentControlSet\Control\Power" /v PlatformAoAcOverride /t REG_DWORD /d 0 /f. Reboot. Verify by running powercfg /a — "Standby (S0 Low Power Idle)" should no longer be listed. This forces legacy S3 sleep which is more stable with GPU drivers.

1. Increase TDR timeout — Open Registry Editor and navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers. Create a new DWORD value TdrDelay and set it to 8. Create another DWORD TdrDdiDelay and set it to 10. These keys don't exist by default. Reboot. This prevents Windows from killing the GPU driver prematurely during slow wake transitions.

1. Disable PCI Express Link State Power Management — Open powercfg.cpl > Change plan settings > Change advanced power settings > PCI Express > Link State Power Management > set to Off for both On Battery and Plugged In. This prevents PCIe power-state negotiation from disrupting the GPU link.

1. Disable Hybrid Sleep — In the same advanced power settings window, go to Sleep > Allow hybrid sleep > set to Off. This prevents the combination of S3 sleep and hibernation file that causes GPU state restoration conflicts.

1. Switch to High Performance power plan — Open Command Prompt as Administrator and run: powercfg /setactive 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c. This prevents aggressive power-state transitions that trigger the sleep/wake GPU crash.

1. Update GPU drivers — Download the latest WHQL-certified driver from NVIDIA or AMD. Use DDU (Display Driver Uninstaller) in Safe Mode for a clean installation. NVIDIA driver 582.28 has been specifically reported as problematic with this update.

1. Hard reset for HDMI detection — If your external monitor is not detected after wake: disconnect power and all peripherals, press and hold the power button for 15-30 seconds to drain residual power, then reconnect everything. Try using DisplayPort instead of HDMI as a temporary workaround.

1. Uninstall KB5077181 as a last resort — Open Settings > Windows Update > Update History > Uninstall updates > KB5077181. Then pause updates for 7 days via Settings > Windows Update > Pause updates. Multiple users confirm HDMI functionality is immediately restored after uninstalling.

If it still doesn't work

Check Event Viewer for specific error sources: open eventvwr.msc, navigate to Windows Logs > System, and filter by Event ID 4101, 41, or 153. This helps identify whether the issue is nvlddmkm.sys (NVIDIA driver), dxgmms2.sys (DirectX), or a power management component. Submit a Feedback Hub report via Win+F under category "Devices and Drivers > Power Management" to help Microsoft track the regression.

Microsoft's official KB page states they are "not currently aware of any issues," but community moderators on Microsoft Q&A have acknowledged the sleep/wake regression and confirmed it stems from changes to Secure Launch and power management. Monitor Windows Update for an out-of-band fix.
