Horizontal black lines due to overheating

Question

I have my SP7 for a little over a month now. It seems when my surface gets pretty hot, some black horizontal lines appear on the top of my screen. They eventually become white and then disappear. Could the lines eventually stay permanently, or as long as it doesn't get TOO hot they'll disappear? Obviously, not heating the computer is the best solution but still... I feel like it's far from overheating and yet they appear! Thanks in advance for your answers.

Hi Cédric Hébert,

Thanks for reaching out to Microsoft Community and posting your inquiry.  

To verify if this is a hardware or software related issue, we suggest going to the UEFI environment every time the issue happen. If the lines would show up on the UEFI settings, this could be a potential hardware issue. Please reach out the Microsoft Surface Support to check your exchange options. If you're located outside the United States, you may also check the Global Team.

If this answers your question, we highly encourage you to inform our Community by clicking on Yes or marking my post as an answer. This will help other members who may have the same issue as you. Otherwise, don't hesitate to update us so we can further assist you.
