Hello, I have a Macbook Air 2017 and I am currently caught up with all of the updates. Colorful vertical and horizontal lines have appeared on my display. Can anyone help with this problem?

Hi,
Try to check your MacBook Air with Apple Diagnostics if it reports display or graphic processor related error(VFD001 to VFD007).
Use Apple Diagnostics to test your Mac - Apple Support
If it is reported error, you'd better off contact Apple Support or make Genius Bar reservation if your local retail Apple Store is open or find opened local Apple Authorized Service Provider to bee examined your MacBook Air.
