NOTE
The exact bandwidth usage is determined by a combination of resolution, refresh rate,
color depth, and compression. Changing any one of these factors may alter the limits
imposed on the others.
To reach 144Hz refresh rate when USB-C bandwidth priority is set to High USB data speed,
your video source device must support display stream compression (DSC).
On model ES07D03, to reach 144Hz refresh rate when USB-C bandwidth priority is set to
High USB data speed, Spectrum must be updated to firmware version 107 or newer.
