Why is my monitor flickering
A flickering monitor screen is the signal, the refresh rate or the backlight.
Test it now
Full-screen white at 100%, then 20% brightness. Change the refresh rate (60 Hz) and the cable. Open the monitor's own menu: flicker across the menu is the monitor, not the source.
What it is
A flickering monitor screen is the signal, the refresh rate or the backlight. Flicker in a screen recording: the graphics driver or an app. Flicker that stops when you change the cable or the refresh rate: the cable or the setting. Flicker at low brightness only: the backlight's dimming. Flicker on every input and in the on-screen menu: the monitor's power board or backlight.
Can it be fixed?
Driver, refresh rate, app: yes, free — update or roll back the graphics driver, set 60 Hz, disable the app's hardware acceleration. Cable: yes, a small repair. Backlight inverter (older laptops) and power boards (monitors): a repairable part. Panel: replace.
What to do
- Screen recording + external monitor: flicker on both = driver; reinstall it.
- Lid tilt: changes = cable; small repair.
- Low brightness only: raise brightness or set a fixed refresh rate.
- Every brightness, every angle: panel quote.
What a repair costs
| United States | usually more than the monitor is worth — a panel swap starts around $150 and most 24"–27" monitors cost less new |
|---|---|
| India | ₹4,000–10,000 for a panel, so a new monitor is often the better buy |

Warranty
Most makers replace a panel under warranty for physical panel faults that are not accidental damage; pressure marks, cracks and liquid damage are treated as accidental and are not covered. For dead pixels, each brand has a threshold (typically 3–5 bright or 5–8 dark pixels on a laptop; Dell's premium-panel guarantee replaces at one bright pixel).
