U2718Q, MacBook Pro, RGB, violet

Question

I am connecting my MacBook Pro 2015 to the the external monitor using a TB to HDMI cable and the RGB format turns the screen violet. Anything I can do to fix it?

DELL-Chris M · Answer

You need to test the monitor on a dedicated Windows operating system PC. You can see here on the Drivers page and also in the User's Guide that the Apple proprietary hardware and operating system were never tested/validated by Dell. You should also post the issue on the Apple Forum and see what other Apple users have done as far as Apple PC troubleshooting and possible Apple proprietary cabling to purchase.
