Provided are a timing controller, and a driving method and a display device thereof. The timing controller may include a detection circuit and a control circuit. The detection circuit may detect a symbol error rate of a drive signal transmitted from a control circuit to a source drive circuit, and send the symbol error rate to the control circuit. The control circuit may automatically adjust a voltage swing of the drive signal according to the symbol error rate of the drive signal, and may enable a magnitude of the adjusted voltage swing to negatively correlate with a magnitude of the symbol error rate. Therefore, electromagnetic interference is effectively reduced, and flexibility in reducing electromagnetic interference is improved. 1. A timing controller comprising a detection circuit and a control circuit , wherein the control circuit is connected to a source drive circuit , and the detection circuit is connected to the source drive circuit and the control circuit respectively;the control circuit is configured to transmit a drive signal to the source drive circuit;the detection circuit is configured to detect a symbol error rate of the drive signal;the control circuit is further configured to adjust a voltage swing of the drive signal according to a symbol error rate detected by the detection circuit, wherein a magnitude of the voltage swing of the drive signal is negatively correlated with a magnitude of the symbol error rate, and the voltage swing of the drive signal refers to a maximum value and a minimum voltage of a voltage of the drive signal.2.
