Bonjour à tous,

Je viens d'acheter un raspberry Pi 4.
J'ai un problème de résolution sur ma TV 4K, je posséde une TV samsung 55 HU 6900, elle est branchée sur un amplificateur pioneer VSX933 (amplificateur compatible 4K).

La résolution sur ma TV est de 1024 x 768 sur raspbian ou sur libreelec.

Voilà le résultat de : "tvservice -m CEA"

Code: Select all

Group CEA has 4 modes:
           mode 4: 1280x720 @ 60Hz 16:9, clock:74MHz progressive
           mode 16: 1920x1080 @ 60Hz 16:9, clock:148MHz progressive
           mode 95: 3840x2160 @ 30Hz 16:9, clock:297MHz progressive
           mode 97: 3840x2160 @ 60Hz 16:9, clock:594MHz progressive
Ci après mon fichier config.txt :

Code: Select all

# For more options and information see
# http://rpf.io/configtxt
# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=1
hdmi_mode=97
#hdmi_ignore_edid=0xa5000080

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800
Pouvez-vous m'aider.

Merci
