--- Comment #12 from Fangru Shao <matrix...@gmail.com> --- Created attachment 179773 --> https://bugs.kde.org/attachment.cgi?id=179773&action=edit With HDMI cable (4k@60Hz) Just after a reboot the system could not detect the external Philips screen anymore no matter how I reconnect the Type-C to DP cable. Here is the screenshot if I use HDMI to HDMI cable to enable it as 4k@60Hz and the command results are as below: $ kscreen-console outputs START: Requesting Config Received config.
