Question about the MacBook M4 2025 Display

Recently, while working in bright sunlight, I noticed such a problem - I noticed such stripes in the upper part along the edge of the display (there is no such thing in other places)

I want to know if this is a manufacturer's defect or a technical issue.

I would like to note that when working indoors and in the dark, these stripes in no way interfere or shine through, they are simply not visible. They are only visible in the sun.

It took me a while to find them and take a picture.

I bought a Macbook a couple of months ago and didn't damage it in any way.

Are these sensors or special display mounts?

Thank you all in advance for your help.

Thank you for the photo.

Lines Atop Mac Screen:

It could be a manufacturing defect, indicating a loose display. Retrace lines are seen, and your LCD screen may just not be centered. So, plug an external monitor into your Mac. If seen, then it might mean you need to update your drivers(through a macOS reinstall). In not seen, then it is an issue with the Mac’s hardware.

A. To Set Up a Genius Bar Appointment:

Set up a Genius Bar Appointment (GBA) at your local Apple Store.

Siart here: Genius Bar Reservation and Apple Support Options - Apple
Scroll down to the Bottom of the page
Click the Get hardware help button
Proceed from there as necessary.

B. What to Bring:

Important: Bring some notes, your original proof of purchase, and create a backup prior to bringing it in. Though not required, bring the power adapter along, in case theirs does not work. See More here: Get your Mac Ready for Service - Apple Support
