Aloha s,
I may be wrong on this but I don’t believe
it can be done from directly inside Cubase.
However my Mac’s OS has a function that
is designed to help when your sight is a lil
on the downside. 
This OS feature has been a real visual helper
for someone like me who is much ‘older than dirt’.
BTW
You did not list your 'puter gear but I am sure
a Windows PC will have a similar function.
HTH (hope this helps)
