Hi, Asus Malaysia, May I ask for the monitor Pro Art PA279CV, if we connected via USB-C, we need to set the usb-c to 2.0 only able to reached 4k 60hz resolution ? if yes, when we switch the usb-c setting to 2.0 instead of 3.0, do it affect performance of other USB port or the data transfer of USBand USB-c Port?
Than You
Hi lewei,
Based on what written on the user manual page 25 & 26, yes it does affect when you change between USB2.0 and USB3.1.
Configures the USB Type C port setting. The USB
Setup parameter affects the output resolution only when the source is
connected to the USB Type C port. Due to the technological differences
between USB 2.0 and USB 3.1, THE maximum USB data throughput
(bandwidth and other related characteristics) varies and therefore
influences the maximum output resolution
* USB 3.1: The data transfer rate according to the 3.1 specification
in USB Type C port can only output the maximum resolution of
4K2K 30Hz.
* USB 2.0: The data transfer rate according to the 2.0 specification
in USB Type C port can output the maximum resolution of 4K2K
60Hz.
• The data transfer rate will remain USB 3.1 when using USB Type C to A
cable.
• The USB Setup setting does not affect the resolution if the source is
connected to the DisplayPort or HDMI port.
Thank you
