Definitely GO.
I never operated B777 but on the closely related B744, only reject after 80Kts for the "big 4"
The big 4 -
Eng Fail
Eng Fire
Predictive Windshear
Capt believes the the aircraft can't fly
Should this failure mode - no PFD or ND F/O side - occur, you still have both Capt displays, lwr EICAS screen avbl as ND and ISFD for attitude etc.
Once in the air with safe flight path assured, then run appropriate checklists and decide your next move.
