B787-10 ND Pop Out Screen Miniaturized Some How

Somehow I have corrupted the ND pop out screen so that when I open it it moves to the bottom left of the of the monitor about the size of a postage stamp. I can enlarge it but when I re-open it it is back to miniaturized every time .
All my other pop out screens are normal size and I think the ND used to be. I can’t for the life of me find the fix.

Update- – I uninstalled the aircraft and all it’s iterations, excited the sim and did a computer re-start. Back into the sim–problems remains.
