    RX 480 DisplayPort behavior

    sauronych

      I have an RX 480 and an LG 34UM67 monitor.

       

      When the card is connected via HDMI and I turn off/sleep the PC, the monitor enters the power saving mode. If I then turn the PC back on, the monitor also turns on automatically.

       

      However, when the card is connected via DisplayPort, instead of entering the power saving mode in the same situation, the monitor simply turns off after 10 seconds, and I have to manually turn it on when waking up the PC.

       

      Is this behavior intentional for DisplayPort? Or is there something wrong with my GPU/monitor/DP cable?
