Narrative:

After departing ewr we were assigned to climb to 11;000 ft after contacting departure control. I was manually flying the aircraft at the time. Departure cleared us direct to a waypoint that was not in our filed route of flight. We were also given a frequency change at the same time. As we were climbing through 9;500 ft the nd/pfd on my side blinked off then back on. This distraction; along with the newly assigned routing caused me to overshoot our assigned altitude by 500 ft. As I started to descend back to 11;000 we were then cleared to climb to FL230. After reaching cruise altitude we briefly discussed the issue and then again after landing in a crew room. It was agreed that in a busy terminal area we should utilize automation to maintain lateral and vertical flight.
