Lately the screen of my MacBook Pro is changing its color without any reason or coherence. It like a soft red / pink-ish tone which you stop recognizing after a while but for the moment of change its quite intense. Besides that I have some issues connecting my external Display. For instance when I’m using bootcamp the screen is not working at all, unless a fullscreen application or game starts. For macOS I haven’t figured out they way it’s working or not. A few weeks ago some USB ports stopped working / weren’t usable for charging, SMC Reset fixed that.
For your colour issues, id look into nightshift mode. A new apple software feature that automatically adjusts display colors later at night to relieve Eye Strain.How to use Night Shift on your Mac As for the external display, I usually run a program called Disk Warrior, since I’m not as experienced with Apple computers. However, this support page should help you with monitor support from Apple: Get help with video issues on external displays connected to your Mac
