I updated my drivers from 26.20.100.7463 to igfx_win10_100.7870.exe after updating, my software such as Monitorain to control the brightness of the monitor are not working

Problem started occurring when I updated from 26.20.100.7463 to newer version of driver. Problem is solved if I roll back the drivers

Problem is 100% reproducible

Laptop Acer Aspire E5-576G

Processor 8250u

When you use the Intel generic driver, you lose customizations made by Acer.

And, since you have dual graphics, you must use both the intel and nvidia driver provided by Acer.

Brightness control for external monitor through software was working until i updated my drivers from 26.20.100.7463

My all other drivers are up to date. Also if I rollback my intel graphics driver then brightness control starts to work again
