hi kite,
thank' s for looking at my small problem.
Yes i have edit the config.txt file because my first time plug with hdmi to TV was' not a success.
My config.txt:
# NOTICE: This file is managed by the Circuit Sword software and is used to
# facilitate HDMI/DPI switching. Do not edit any lines that start with "# CS .."
# The following settings are used by the software to determine the state
# For instance, the STATE of 'IDLE' means that this file is complete and won't
# change. The state of 'REBOOTING_TO_HDMI' means this file is in transition to
# becoming HDMI enabled and so you should NOT edit the file at all in this case.
# This works by removing 1x '#' symbol from each line within the HDMI block. This
# means anything with one '#' will end up being enabled. Anything with 2x '#'s
# will remain disabled (e.g. comments, or alternative modes)
# If all goes wrong, restore the config.txt file from the backup:
# sudo cp ~/Circuit-Sword/settings/config.txt /boot/config.txt
# CS CONFIG VERSION: 1.0
# CS CONFIG STATE: IDLE
# For more options and information see

# Some settings may impact device functionality. See link above for details
# Additional overlays and parameters are documented /boot/overlays/README
# Some settings from the orignal config.txt
