My external monitor looks like crap after installing Sierra.

My external monitor looks like crap after installing Sierra.

Before it was really crisp, now it's blurry fonts, jagged anti aliasing on icons and color banding on backgrounds. I have a Mac Book Pro, my external monitor is a DELL U2515H 2048. What can I do?

If you search the Sierra forum you will find other external monitor users with issues.


Please file your own bug report so that Apple gets lots of individual messages that the graphic driver in Sierra needs work.
