Abstract: 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.
