The embodiment of the present invention provides a display driving circuit, a control method thereof, and a display device and relates to the technical field of display. A problem that a row of sub-pixels which receives a clock signal quickly discharges to cause other sub pixels have a charge difference when a front end signal is discontinuous and the clock signal is converted to an intermediate level can be solved. The display driving circuit includes a control sub-circuit and a gate driving sub-circuit. The control sub-circuit is used for receiving an effective display data gating signal andproviding an effective clock signal to the gate driving sub-circuit according to the effective display data gating signal, or the control sub-circuit is used for generating a first signal adjustmentinstruction when the loss of the effective display data gating signal is judged and controlling the output end of each stage of shift register in the gate driving sub-circuit to output a non-gating signal according to a first signal adjustment instruction.
