@Thomas-Blottiau Réglé! merci tout le monde!

@acris je teste, merci!

@Substring j'ai ré installé la version 4.0 de recalbox d'origine (avec les paramètres par défaut).
je viens de modifier la ligne: global.videomode=default
rien n'a changé.
L'écran est décalé dès son allumage (ES + émulation)...
Je sèche...

@Substring Bonjour, voici la référence de l'écran !

Salut tout le monde,

voici ma config,
Raspberry Pi model: Pi3
Recalbox version (build) : Version4.0
Matériels (Micro SD, Power Supply, etc.): micro sd, ecran d'ordi, cable hdmi vers VGA

Problème rencontré (même après lecture des posts et des solutions apportées aux uns et aux autres)

Je me construit mon bartop, tout est prêt mais j'ai ce ***** de probème d'affichage sur l'écran: tout est décalé vers la droite...
je ne sais plus quoi faire, après un après-midi passé sur ce forum...
Merci de votre aide.

Voilà la config affichée

# ------------ H - HERE IT IS - GLOBAL EMULATOR CONFIGURATION ------------ #
## The global value will be used for all emulators, except if the value
## is redefined in the emulator

## Set game resolution for emulators
## select your mode from the command : tvservice -m [MODE]
## CEA 5 HDMI : 1920x1080 @ 60Hz 16:9, clock:74MHz interlaced 
## CEA 4 HDMI : 1280x720 @ 60Hz 16:9, clock:74MHz progressive
## use 'default' for using the default resolution
## (string)
global.videomode=DMT 47 HDMI

## Shader set 
## Automatically select shaders for all systems
## (none, retro, scanlines)
global.shaderset=retro

## Once enabled, your screen will be cropped, and you will have a pixel perfect image (0,1)
global.integerscale=1

## Set gpslp shader for all emulators (prefer shadersets above). Absolute path (string)
global.shaders=

## Set ratio for all emulators (auto,4/3,16/9,16/10,custom)
global.ratio=4/3

## Set smooth for all emulators (0,1)
global.smooth=1

## Set rewind for all emulators (0,1)

global.retroachievements.username=
global.retroachievements.password=

## Set retroarch input driver (auto, udev, sdl2)
## If you don't have issues with your controllers, let auto
global.inputdriver=auto

## If you do not want recalboxOS to generate the configuration for all emulators (string)
;global.configfile=/path/to/my/configfile.cfg

# ------------ I - EMULATORS CHOICES ----------- #
## You can override the global configuration here
## Here is the snes example
;snes.videomode=CEA 4 HDMI
snes.core=snes9x_next
;snes.shaders=/recalbox/share/shaders/shaders_glsl/mysnesshader.gplsp
;snes.ratio=16/9
;snes.smooth=0
;snes.rewind=1
;snes.autosave=0
snes.emulator=default
;snes.integerscale=0
## If you do not want recalboxOS to generate the configuration for the emulator : 
;snes.configfile=/path/to/my/configfile.cfg

## Default cores for RPi3
snes.core=snes9x_next
gba.core=mgba
mame.core=mame078
nes.core=fceunext

## NeoGeo emulator 
## You can use pifba or a libretro core (fba2x,libretro)
neogeo.emulator=libretro
## If you set libretro as neogeo.emulator, the line below sets the retroarch core (fba,imame4all)
neogeo.core=fba

## N64 emulator is configured to display a screen with a 640x480 resolution (native n64 resolution)
## So you must use one of these video modes (DMT 4 HDMI,CEA 1 HDMI).
## If your screen is not compatible with one of these video modes, please check the recalbox's wiki.
n64.videomode=DMT 4 HDMI
## If you are using a CRT screen, please change the setting above with this one : 
# n64.videomode=default
