Issue: Your Lenovo Laptop or tablet display is often dim or dull at 100% maximum brightness in a low light situation, and you don;t have auto brightness turned on. Like Nigel you’re turning (punching?) the brightness key up to 11 but it ain’t happening.
Cause: Lenovo Vantage or System Brightness settings. The Lenovo Vantage app has settings to manage brightness that aren’t available via the normal Windows display controls. System brightness settings are Microsoft, and seem to get lost on the way home sometimes.
Solution – Lenovo Vantage (if installed)
Disable color temperature
- Launch Lenovo Vantage
- In Settings: Device > My Device Settings > Display and Camera > Display > Daytime Color Temperature
Solution – Systems Settings
Turn Automatic Brightness On and then Off
OS version: 1809 (17763.529)
- Go to: Settings > Display Brightness and Color
- Turn On this setting (yes on): Change brightness automatically when lighting changes
- When I turned On Auto Brightness the display, already set to 100% brightness, got brighter. If anything it should have gotten darker in a dark room.
- Now turn Automatic Brightness back Off
- Yes! Now we have light with full 100% brightness! By… changing the brightness settings back to what it was – off.
