Currently my laptop screen shows the problem like the video above: There are some blacklines keep flickering in a zone near bottom edge of it.
This problem normally starts appearing after me using the laptop for about 15 to 30 minutes.
I had took some screenshot or video recordings, but it doesn't show this issue.
I am using an HP Omen 15T version 2017, with i7-7700HQ, GTX 1050Ti,a 120Hz screen and running windows 10.
Any help is really appreciated and I thank you in advance for taking a bit of your time to help me out if you can
