We experienced issues with our flight displays right after takeoff. The flight director bars on the Captain's side disappeared and the flight director coupled to the First Officer's side. We were on runway heading and climbing to 5;000 FT. We tried to couple back to the Captain's side but it would not switch back. We were given a turn towards [destination] and 10;000 FT so we continued to climb while diagnosing the problem. We checked the electrical page and the generators were all producing power; and there were no popped circuit breakers. We were not getting any EICAS messages or any indications on the Captain's displays such as red Xs to indicate IC-600 1 failure. As we continued to climb; the First Officer's MFD and PFD displays went dark; followed by the Captain's side. Both side displays blinked briefly off and on a few times; then returned with the Captain side displaying ATT2; MAG2; SG2; and ADC2. This lasted for a minute or so; then returned back to normal. We tried to couple back to the Captain's side and it would couple over; but whenever the HDG or NAV button was pressed; it would couple back to the First Officer's side. We tried this a couple of times with the same results. The displays would flicker; then it would couple over to the First Officer's side. The flight director bars on the Captain's side would flicker on and off. We continued on course; making plans to divert and decided to call Maintenance Control and Dispatch. While talking to Maintenance Control we also told ATC that we were negative RVSM and were assigned 27;000 FT. Maintenance Control came back saying there was no issues in the record and could we make it to [destination]. We did not know if we had enough fuel at that altitude and were still considering [a divert airport] which was ahead of us. While talking to Maintenance Control; Dispatch calculated new number and sent them to us showing that we could make it to [destination]. Also; the displays had been steady for a while as long as it was coupled to the First Officer's side. We decided to continue towards [destination] with diversionary airports [in mind] if any problems returned. We informed ATC and they gave us 28;000 FT; which helped with the fuel burn. We continued without any problems until we were on the visual approach. We hit some wake turbulence and the displays went momentary blank again; followed by ATT2; MAG2;SG2; and ADC2 on the Captain's side. This lasted around 30 seconds; then returned to normal. We landed uneventfully on the visual approach and taxied to the gate with no problems.
EMB-140 Captain reported erratic flight displays (ND and MFD) shortly after takeoff. After consulting with Dispatch and Operations the flight continued to destination.
