Frequently asked questions

Why does my monitor flicker when gaming?

Check the refresh rate in Display settings and disable variable refresh rate, which can strobe on LED-backlit panels. Then update the graphics driver.

Why does my laptop screen flicker when I move the lid?

That's usually a damaged display cable in the hinge. Update the driver first; if it persists, the cable needs repair.
