The Lenovo Vantage app has settings to manage brightness that aren’t available via the normal Windows display controls and Windows 10 System brightness settings… seem to get confused, possibly by Lenovo Vantage.
Like Nigel you’re turning (punching!) the brightness key up to 11 but it ain’t happening.Ĭause: Lenovo Vantage color temperature setting or Windows 10 Brightness settings. 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.
