Thank you for posting in the Apple Support Communities. It sounds like you're having some trouble with the display on your XS Max, correct? If so, we would love to help see if we can get the issue resolved for you. Is the issue continuous? Does restarting the device change anything?
Also, let's go ahead and see if you have any iOS updates that need to be installed. If so, we recommend backing up the device and updating to see if the issue remains.
