Abstract
A display adjusting device, a power source circuit, a display device and a display adjusting method are provided. The display adjusting device includes a start signal detection unit, configured to, in a case that a gate drive circuit including multiple stages of gate drive circuit units scans multiple rows of gate lines arranged in the display panel, detect a gate drive signal outputted by a last row of shift register unit included in each stage of gate drive circuit unit, where the gate drive signal serves as a start signal of a next stage of gate drive circuit unit adjacent to the stage of gate drive circuit unit, and a gamma main voltage setting unit, configured to set a corresponding gamma main voltage based on the start signal.
