The screen flickers or blanks when HDR is switched on
Why does my laptop screen flicker when I toggle HDR on?

Short answer
Switching HDR on changes the panel's colour depth and often its refresh timing, so the link between the graphics chip and the screen is renegotiated. Persistent flicker after that usually comes from variable refresh fighting the change, a marginal cable on an external screen, or adaptive brightness reacting to HDR content. The quickest thing to try first: accept one flash, investigate the rest — A single black flash while the mode changes is normal. Only continuous flicker afterwards is a fault worth chasing. Most people are done in about 15 minutes.

Sounds like this
- •A black flash each time HDR is enabled
- •Repeating flicker in games or video
- •Worse on battery than plugged in

Turn off Dynamic Refresh Rate and variable refresh
Settings, System, Display, Advanced display, set a fixed refresh rate instead of Dynamic. Then in the NVIDIA or AMD control panel disable G-Sync or FreeSync for windowed mode. Variable refresh plus HDR is the most common flicker combination.

Switch off content adaptive brightness
Settings, System, Display, Brightness, untick 'Help improve battery by optimising the content shown' and 'Change brightness automatically'. These dim and brighten constantly against HDR content.

Update the graphics driver from the chip maker
Install directly from Intel, AMD or NVIDIA rather than Windows Update, and choose a clean install. HDR handover bugs are fixed frequently in these drivers.

On an external screen, change the cable and port
Use a certified DisplayPort 1.4 or HDMI 2.1 cable under two metres, plugged straight into the laptop rather than a dock or adapter. HDR at high refresh sits near the cable's bandwidth limit and marginal cables flicker.

Keep the charger connected
Some laptops drop the panel to a lower power state on battery, which conflicts with HDR. If the flicker disappears while plugged in, set HDR to switch off on battery in Settings, System, Display, HDR.
If none of that worked
Run the Windows HDR Calibration app from the Microsoft Store; it resets the panel's HDR metadata, which clears flicker caused by a bad stored profile.
