Shortly after takeoff from Runway 34L we got an ATC Fault EICAS message. Tried to switch transponder from 2 to 1 but that did not resolve the EICAS message. At about 1;500 ft. AGL we got a TERR POS EICAS message. When we asked Departure Control if they saw any issues with our transponder they responded that they did not but they were suspecting 5G interference because many aircraft were reporting anomalies like ours. Both the ATC Fault and TERR POS EICAS messages went away after we climbed above FL 220.
Captain reported climbing out of DEN; EICAS fault of transponder and TERR POS part of the GPS system.
