rMB reverting to default display setting on its own

[lo100469]

hi,
It happened already 3 or 4 times the last 2 weeks. When going out of sleep my rMB does not keep the 1440/900 resolution, it goes back to default.
I did reset NVRAM this morning, anything else I should be doing or checking?
Thanks

Tried repair permissions?

Unlikely to fix, but worth a shot...

What OS version are you running?

Ok i did a repair permission, we will see if the issue comes back...
