My B575's screen occassionally has flickering horizontal lines appear.
I read that I can fix this problem tightening some screws, but the instructions I read were for a different Lenovo laptop.
What are the steps I should take for a B575?
Thanks in advance !

This issue might be with your Display driver. You need to install the updated display driver according to your Operating System from the below mentioned web link.
You can also update your BIOS from there also.
Alternatively please refer the below mentioned Web link which you are seaching for.
