The quickest way to reset the graphics driver in Windows 11 or Windows 10 is:
Windows key + Ctrl + Shift + B
Press all four keys together and release them. The screen may briefly turn black or flicker, and you may hear a beep before the desktop redraws.
This shortcut is useful when the display freezes, flickers, goes black, or stops updating while Windows is still running. It does not restart the PC, reinstall the graphics driver, or reset NVIDIA, AMD, or Intel settings to factory defaults.
What Windows + Ctrl + Shift + B Actually Does
Microsoft recommends Windows + Ctrl + Shift + B as a troubleshooting step for display problems such as blank screens, flickering, and external monitors that stop responding.
It refreshes the graphics/display path without requiring a full Windows restart.
Try it when:
- The screen suddenly goes black but the PC remains powered on.
- Audio continues while the picture is frozen.
- The desktop stops redrawing.
- A display misbehaves after waking from sleep.
- An external monitor suddenly stops updating.
- The screen flickers after opening or closing an application.
After pressing the shortcut, wait several seconds.
A short black screen or flicker is normal during the reset.
What the Shortcut Does Not Reset
The keyboard shortcut is frequently described online as a complete GPU reset, but that can be misleading.
It does not:
- Reinstall the NVIDIA, AMD, or Intel driver.
- Restart Windows.
- Erase files or applications.
- Restore NVIDIA Control Panel settings.
- Factory-reset AMD Software.
- Reset Intel graphics preferences.
- Restore custom resolution or color settings.
- Repair a failing GPU, monitor, cable, or power supply.
Think of it as a quick graphics-driver/display recovery step rather than a permanent repair.
Check Whether Windows Is Still Running
The shortcut is most useful when the display has stopped responding but Windows itself is still alive.
Before forcing the computer off, check for signs of activity:
- Press Caps Lock or Num Lock and see whether the keyboard indicator changes.
- Listen for music, game audio, notifications, or a voice call.
- Press Ctrl + Alt + Delete and wait for the security screen.
- Check whether the mouse pointer or other displays still respond.
If Windows is responding but the screen is not, try Windows + Ctrl + Shift + B once.
If the entire computer is completely frozen, the problem is broader than the display driver.
If the Graphics Reset Shortcut Does Not Work
Do not keep pressing the shortcut repeatedly.
Try Ctrl + Alt + Delete
Press:
Ctrl + Alt + Delete
If the Windows security screen appears, the operating system is still responding.
You can open Task Manager to close a frozen application or use the power menu to restart Windows normally.
Check the Display Mode
Windows may be sending the desktop to another monitor.
Press:
Windows key + P
This opens the display projection choices. It is particularly useful after connecting or disconnecting a monitor, television, dock, or projector.
Choose the appropriate mode, such as PC screen only, Duplicate, or Extend.
Check the Monitor and Cable
A graphics reset cannot repair a physical display connection.
Confirm that:
- The monitor has power.
- The correct HDMI, DisplayPort, or USB-C input is selected.
- The display cable is fully seated.
- A dock or adapter has not lost power.
- The cable is connected to the intended GPU output.
On a desktop with a dedicated graphics card, the monitor normally connects to the graphics card rather than the motherboard video output.
When possible, test one monitor directly without a dock, splitter, or converter.
When the Reset Works but the Problem Keeps Returning
A successful graphics reset only means Windows recovered the display. It does not explain why the display stopped responding.
Microsoft’s Windows Display Driver Model includes Timeout Detection and Recovery (TDR). When Windows detects that the GPU has taken too long to complete work, it can attempt to reset the graphics hardware/driver and restore the desktop.
A recurring black screen, freeze, or driver recovery therefore deserves further diagnosis.
Check the Graphics Driver
Open:
Device Manager > Display adapters
Identify the GPU and open Properties > Driver.
If the problem began after a recent driver update, Roll Back Driver may be more appropriate than installing another newer version immediately.
If the driver is old, corrupted, or Windows is using Microsoft Basic Display Adapter, install the correct driver from the PC manufacturer or the official NVIDIA, AMD, or Intel source.
For NVIDIA systems that need a full reinstall, see How to Reinstall NVIDIA Drivers on Windows.
Avoid third-party driver-download sites.
Use Task Manager to Diagnose Flickering
Microsoft recommends a useful test when the main symptom is screen flickering.
Open Task Manager with:
Ctrl + Shift + Esc
Watch whether Task Manager flickers along with the rest of the screen.
- Task Manager also flickers: the display driver is a stronger suspect.
- Task Manager remains stable: an incompatible application is more likely.
Recent overlays, screen-recording software, RGB tools, remote-display programs, wallpaper utilities, and other applications that interact with graphics are worth testing.
If NVIDIA Overlay is the trigger, use How to Turn Off NVIDIA Overlay rather than repeatedly resetting the graphics driver.
Test One Display
Disconnect secondary monitors and test one display directly.
A multi-monitor setup introduces additional variables:
- Different refresh rates
- Different resolutions
- DisplayPort/HDMI cables
- USB-C docks
- Adapters
- GPU ports
- Variable refresh-rate features
If the problem disappears with one monitor, reconnect the other displays individually.
Resetting App Graphics Preferences Is Different
Windows also lets you choose which GPU an application should use.
Open:
Settings > System > Display > Graphics
Select the affected application and open its graphics options.
Choosing Let Windows decide removes a forced power-saving or high-performance GPU preference for that app.
This can help when a program is launching on the wrong GPU, but it is not the same as pressing Windows + Ctrl + Shift + B.
Reset NVIDIA, AMD, or Intel Settings Only When Needed
If the problem began after changing GPU control-panel settings, restore those settings from the manufacturer’s application.
For example, NVIDIA Control Panel provides a Restore option under Manage 3D settings.
AMD Software and Intel graphics utilities have their own reset/default controls, although their names and locations can change between versions.
Before resetting them, note any custom:
- Color settings
- Scaling
- Frame-rate limits
- Game profiles
- Multi-monitor configuration
- Performance settings
These controls reset configuration. They do not repair a corrupted display driver.
Do Not Change TDR Registry Values as a Routine Fix
You may find guides recommending changes to registry values such as TdrDelay to stop graphics-driver timeouts.
Microsoft documents the TDR registry keys for driver development, testing, and debugging and explicitly says end users should not manipulate them.
Increasing a timeout can hide the symptom without fixing the application, driver, overheating, unstable overclock, power problem, or failing GPU responsible for the hang.
Do not treat TDR registry edits as a normal black-screen fix.
When a Graphics Reset Points to a Bigger Problem
Investigate beyond Windows when black screens or GPU resets happen repeatedly during gaming, rendering, or other heavy workloads.
Check for:
- GPU overheating
- Unstable GPU overclock or undervolt
- Loose GPU power connectors
- Inadequate or failing power supply
- Damaged display cable
- Driver crashes
- GPU errors in Device Manager
- Artifacts before the screen goes black
- Problems that occur before Windows loads
A VIDEO_TDR_FAILURE (0x116) blue screen is particularly important. Microsoft documents this stop code as a failed attempt to reset the display driver and recover from a GPU timeout.
That is not the same as an ordinary display glitch successfully fixed by the keyboard shortcut.
The useful boundary is simple: use Windows + Ctrl + Shift + B for a temporary display/graphics-driver hang. If you need the shortcut repeatedly, diagnose the driver, application, display connection, temperature, power, or GPU instead of treating the shortcut as the repair.
