1. Video transmission follows the Bucket Effect
The maximum achievable image quality, refresh rate and bandwidth of your setup are capped by the component with the lowest specification among three parts: graphics card, monitor and transmission cable.
For example: Even if your graphics card and cable fully support full-spec DP 2.1 Cable, the final output performance will still be limited to DP 1.4 Cable if your monitor only complies with DP 1.4 Cable. You cannot unlock the full potential of high-end hardware. Always match the specifications of cables and devices when purchasing.
2. HDMI delivers superior stability for long-distance transmission
Signal attenuation is inevitable during cable transmission. The high-bandwidth feature of DP suffers far more severe signal degradation over extended lengths, which easily triggers image quality loss and unstable signal performance for long cable runs.
In contrast, HDMI Cable feature optimized attenuation control, making them the better choice for long-distance scenarios such as surveillance wiring, on-location shooting and long-range screen casting.
