LCD eDP Video Cable (40-Pin)
High-refresh-rate operation requires robust signal integrity across all four lanes of the Embedded DisplayPort (eDP) interface to maintain the necessary pixel clock. Physical degradation of the cable near the hinge assembly increases electrical resistance and signal attenuation, preventing the GPU from successfully negotiating the High Bit Rate (HBR) protocols required for 144Hz+ output. Replacing the eDP cable restores the full bandwidth path between the motherboard's display controller and the panel's timing controller (TCON).
