The present invention discloses a gamma buffer output compensation circuit, a drive circuit and a resistance setting method thereof. The gamma buffer output compensation circuit comprises a set of variable compensating resistor modules which are respectively connected to each output terminal of the gamma buffer and have regulable resistance. The present invention uses the method of setting variable compensating resistor modules with regulable resistance in front of each output terminal of the gamma buffer to replace the existing compensating resistors with fixed resistance. The resistance of the compensating resistors in front of each output terminal can be regulated through external operation so that the same compensation circuit can be applied to different types of machines. Therefore, the gamma buffer output compensation circuit can be directly developed in advance without regard to the difference of different types of machines, and the resistance of suitable compensating resistors can be regulated in later period. Thus, the generality of gamma buffers is increased, and the development cycle of machines is reduced.
