VESA Certified DisplayPort 1.4 Cable (HBR3)
The AW3423DW pushes the limits of DisplayPort 1.4 bandwidth at 175Hz/10-bit; insufficient shielding or physical degradation of the copper pairs leads to electromagnetic interference (EMI) and bit-error rate spikes. This causes the G-Sync module to lose synchronization with the GPU, resulting in intermittent black-frame insertion or visible flickering. Replacing the link medium with a certified HBR3-rated cable restores signal integrity and sync-lock stability.

Main Logic Board (Scaler Board)
This board houses the dedicated G-Sync hardware module and the timing controller (T-CON). Thermal fatigue or component failure within the scaler’s power-delivery circuit can cause voltage instability during variable refresh rate (VRR) transitions, leading to luminance oscillations or failure to process incoming DisplayPort packets accurately, manifesting as persistent screen flickering.
