Timing controller, display device, and signal adjustment method

A timing controller, wherein the timing controller comprises a receiving circuit, a timing control circuit, and a plurality of insertion loss circuits;

• the receiving circuit and the insertion loss circuit are respectively connected to the timing control circuit;
• the receiving circuit is configured to receive N frames of signals;
• the timing control circuit is configured to:
• detect a bit error rate of an (M−1)th-frame signal in a blanking interval of an Mth-frame signal;
• adjust a swing of the (M−1)th-frame signal according to a target swing value corresponding to the bit error rate of the (M−1)th-frame signal;
• and
• select the corresponding insertion loss circuit according to the target swing value corresponding to the bit error rate of the (M−1)th-frame signal to consume energy generated when adjusting the swing of the (M−1)th-frame signal;
• wherein M and N are both positive integers, and M is greater than 1 and less than or equal to N.
