Salut @Substring, merci pour ton aide !
J'ai testé 4 écrans DVI hier :

  • Un seul fonctionnait sur Raspbian et sur Recalbox
  • Deux fonctionnaient sur Raspbian mais pas sur Recalbox
  • Le dernier ne fonctionnait ni sur Raspbian ni sur Recalbox

Voici mon config.txt. (EDIT = par contre le formatage automatique me remplace tous les # par des lignes en gras sur le forum, j'ai remplacé par des dièse)

♯ 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=1

♯ 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

♯ Uncomment some or all of these to enable the optional hardware interfaces
♯dtparam=i2c_arm=on
♯dtparam=i2s=on
♯dtparam=spi=on

♯ Uncomment this to enable the lirc-rpi module
♯dtoverlay=lirc-rpi

♯ Additional overlays and parameters are documented /boot/overlays/README

♯ Enable audio (loads snd_bcm2835)
dtparam=audio=on

♯ NOOBS Auto-generated Settings:
hdmi_force_hotplug=1

Merci !
