Screen brightness setting maxed but not bright

Question

Screen brightness setting maxed but not bright.

Hello everyone, this is my first post regarding technical support ever, thanks in advance for any help provided.

I have a Lenovo flex 15 laptop that is running windows 8.1.

As the title stats my screen max brightness had been lowered quite a bit and after messing around with power settings, going to the manufactures website to download another graphics driver, using Google and searching through forums I find myself here wondering what to do next.

My biggest success/temporary fix came from downloading and installing the lenovo recommended driver for windows 8.1(Intel Extreme Graphics Driver) which restored my screen it its full brightness for about 10 minutes before crushing my hoped by reverting back into darkness, of course I checked the settings again and removed/reinstalled the driver a few times and got similar results each time so I decided to seek out professional assistance if possible.

Solution 1

SOLVED - Go to power options, high performance, change plan settings, advanced, display, change enable adaptive brightness to off

Solution 2

It is most likely caused from low voltage at LCD inverter. This is responsible for producing backlight. You may have to replace the inverter.

Could it be the automatic screen brightness getting in the way? Disable Auto-Brightness Adjustment in Windows 8.1. Or maybe you have inadvertently covered the ambient light sensor.

Thanks for your response, I have checked power options again tried to mess with driver settings and imposed the high-performance power plan, and its still not working.

Did you notice any difference (even small) when increasing brightness from the display driver ?

[john]

No difference at all so far as I can tell.

I've had this several times, It has always been a software issue.
