Macbook pro 2017-Second monitor is not full screen
Hello,
I'm using second monitor for my Macbook pro (not mirror, just as secondary screen), but unfortunately it's not filling the entire screen for some reason.
I've tried almost everything but it looks like a weird bug.
Is there any solution for this problem?
I'm attaching a photo of the monitor (the black area should be filled).
Thank you for helping
