Hi Mr. YK Jung, I did test and find it is caused by AML's commit. In this commit, system will set resolution to NULL when HDMI is unplugged. But it doesn't check saved mode after HDMI is plugged again. Since this commit is a common patch for all vendors. Will you report it to SKB JIRA and ask AML to fix it ? Thanks ! ====== HDMI is unplugged, set output mode to null ============== ... SystemControl: Matched uevent message with pattern: DEVPATH=/devices/virtual/amhdmitx/amhdmitx0/hdmi SystemControl: HDCP TX switch_name: hdmi ,switch_state: 0 SystemControl: onTxEvent switchName:hdmi hpdstate:0 state: 1 SystemControl: write /sys/class/display/mode, val:null end .... ====== set output mode to best mode after HDMI is plugged ============== ... SystemControl: curMode = null outputmode = 1080p60hz SystemControl: write /sys/class/display/mode, val:1080p60hz end .. set_null_HDMI_unplug.png (51,973 bytes) |

Hi Kerwin As far as I know, it doesn't happen in INTEK and INNOPIA. Only FXN Smart3 have this issue. Anyway, I'll discuss it with Amlogic Thank you YK.Jung |

Hi Kerwin INTEK and INNOPIA solved this issue in a different way. Amlogic has released a patch on this issue at today. If we apply this patch, the issue will be solved. Thank you hdmi_patch.png (11,128 bytes) |
