Timo Glock was crowned series champion on 30 September after winning the final round at Valencia, with Brazilian Lucas di Grassi finishing second.
Michael Ammermüller, who was driving for defending teams' champion ART Grand Prix was injured and missed next two races.
Safety car was instantly deployed and majority of the field opted to make their mandatory pit stop.
At Monaco, only one race was held which was won by Pastor Maldonado who had celebrated a victory in World Series there in the previous year.
Viso's teammate Javier Villa won the sprint race, becoming youngest ever winner in GP2 at that time (the record was broken a year later by Sébastien Buemi).
Glock then collided with Ricardo Risatti during reconnaissance lap of the sprint race and failed to start.
di Grassi got good chance to close the gap on him but couldn't do better than third in a race which was won by the Indian Karun Chandhok.
The gaps in the race were exceptionally big, only five drivers finished in the same lap with the winner Vitaly Petrov.
Glock got to start from the front row in the sprint race while di Grassi's place was near the back of the grid.
Glock confirmed his championship with the victory in the final race, 11 points ahead of di Grassi.
All of the teams used the Dallara GP2/05 chassis with Renault-badged 4.0 litre (244 cu in) naturally-aspirated Mecachrome V8 engines order and with tyres supplied by Bridgestone.
