Screen turns black when HDR is enabled

Recover the graphics path and test a supported HDR bandwidth mode before changing profiles.

Quick diagnosis

HDR increasing bit depth or color payload can expose a marginal link even when SDR remains stable.

Common symptoms

The display loses the image immediately when Windows HDR is turned on.
The behavior is repeatable with the same display state.
Changing an unrelated Windows preference does not reliably fix it.

Likely causes

Unsupported refresh/bit-depth combination, cable or adapter margin, input mode, or graphics-driver transition.
A connection, driver, or configuration boundary affecting the display.
Hardware failure only if the symptom follows the same display across controlled comparisons.

Before changing anything

Record the current display settings and connection path.
Change one variable at a time.
Keep a known-good comparison device, port, mode, or application available.

Diagnose it in this order

1
Create a repeatable baseline
Reproduce the symptom in a simple Windows surface and record exactly when it occurs: The display loses the image immediately when Windows HDR is turned on.
2
Run the discriminating test
Press Windows+Ctrl+Shift+B once, then test direct connection at native resolution, 60 Hz, and a supported HDR bit depth.
3
Apply the narrow fix
Use a cable and both endpoint ports rated for the mode, enable the monitor’s documented HDR input setting, and update supported firmware/drivers.
4
Repeat the original comparison
Keep every unrelated setting fixed and repeat the baseline for longer than the normal failure interval.

Solutions

Screen turns black when HDR is enabled

Use a cable and both endpoint ports rated for the mode, enable the monitor’s documented HDR input setting, and update supported firmware/drivers.

Verify the fix

Toggle HDR three times and complete one sleep/wake cycle without signal loss.
Restart or reconnect once and repeat the same controlled test.
Confirm the change did not create a new failure in the comparison state.

Roll back safely

• Restore the recorded display settings, connection, driver, or mode if the result is not repeatable.

When to stop and escalate

• If the symptom follows the display across another PC or source after the documented checks, use manufacturer support or warranty service.

Frequently asked questions

Why test before changing several settings?

A one-variable comparison shows whether the proposed mechanism actually controls the symptom and preserves a safe rollback.
