 +  * ''Identifier'' will need changed for different display connections and drivers
  
-  * 4k@60Hz CVT-RB +====== Config File ======
-  * Fixes unstable HDMI at 4K@60Hz, and overly-bright colors on DisplayPort +
-  * :!: The ''grep'' here confirms the expected Modeline ((if grep reports nothing, use whatever is reported instead)) +
-  * :!: This cannot be used on Wayland currently +
-  * :!: This expects ''amdgpu'' DDX driver to be used ((''modesetting'' has a 4K RB resolution without any settings require on Xorg))+
