Question: Horizontal Thin Grey Lines Across

Hi,


On initial startup of my MacBook, or lifting up the lid from sleep, thin grey/black lines appear across the very top of my screen. After several minutes the lines slowly fade until they disappear.


I have reset the NVRAM, SMC and also re-installed the operating system yet the issue still occurs.


What I am struggling to decide on is whether the fault is due to a hardware issue or technical issue. Due to the fact that the lines disappear after the monitor being active for a little while I am presuming it is a hardware fault.


I purchased the MacBook in September 2017, and had to have a screen replacement in December 2017 because of another hardware issue that was unexplainable.


Any support would be much appreciated!


Thank you in advance.

MacBook Pro with Retina display, macOS High Sierra (10.13.3)
