  • Why am I not able to display resolutions of 4096 x 2160 @ 30 Hz?
    • Click [Display Setting] > [Advanced Display Settings], then choose the desired resolution manually.
    • Ensure the device, display and cable all support 4096 x 2160 @ 30 Hz HD.
  • Why does my PD charging time vary?
    The upstream device (laptop) will auto-adjust the power input based on the battery level at that current time.
  • Why won’t my HDMI, Mini DisplayPort and VGA displays show different screens?
    Most MacBook laptops do not support MST, allowing you to extend only one screen and mirror the other.
