Grey:white frame around MAC display

[Sony76]

hi there, I have a grey/white border around my MAC screen. I have tried restarting, launching teminal and typing Killall Dock and relaunching Finder from apple icon. The problem has got better but is still there. Any suggestions??

Hello,

-Which model Mac
-What version of OS X/macOS?

Normally, that is a result of Exposé getting stuck. Sounds like you tried the steps here: Greyed frame around Mac display

Can you take a photo and upload it, so we can see the issue?
