RX 580 HDMI only 4K@30Hz in Windows 10

Hi,

 

RX 580 only gets 4K@30Hz in Window 10 using HDMI connection. 

4K@30Hz is achieved with disabling HDMI Deep Color setting on LG 4K Monitor, it gets a blank screen if HDMI Deep Color is enabled.

 

Using macOS Catalina (the same PC, Monitor and HDMI Cable), it can get 4K@60Hz. with HDMI Deep Color enabled in the monitor.

 

Using DisplayPort connection, it can get 4K@60Hz on both Windows 10 and macOS Catalina.

 

So I think there is a problem in AMD graphics driver.

 

Any solution on this problem is appreciated.
