VESA Certified DisplayPort 1.4 Cable
High-refresh 1440p panels require significant bandwidth; flickering at 144Hz is frequently the result of electromagnetic interference or signal attenuation in non-certified cables. A VESA-certified cable ensures the physical layer can maintain the differential signaling required for the DisplayPort HBR3 standard without packet loss.

Monitor Main Board (AD Board)
The main board contains the scaler and timing controller (TCON) logic. Flickering that resolves by changing internal OSD settings like 'Just Scan' or 'Adaptive-Sync Off' indicates a failure in the scaler's ability to process variable refresh rate metadata or maintain vertical sync timing at the hardware level.

AC/DC Power Adapter (19V 3.42A)
Instability in the external power brick can introduce voltage ripple into the monitor's internal rail system. This ripple can cause the backlight driver or the panel's logic gate drivers to fluctuate rapidly, manifesting as visible screen flickering or momentary blackouts.
