@Substring merci beaucoup pour ta réponses et votre réactivité!

@rockaddicted merci pour ta réponse. J'ai testé et effectivement cela semble un peu plus grand.
Ma question va paraître peut-être bête mais lorsqu'on branche la recalbox sur un écran d'ordianateur, n'est-ce pas en plein écran?

@Substring il est donc impossible d'avoir l'image en plein ecran sur une tv full hd?

Il est donc impossible d'avoir l'image en plein ecran sur une television full hd?

Bonjour,
je vous demande de l'aide car il m'est impossible d'avoir mes jeux sur la totalité de mon écran (grande télévision), il semble que cela ne fonctionne uniquement pour le menu général. Dès que je selectionne un jeu l'ecran est très réduit...
J'ai pourtant modifié mon recalbox.conf (voir ci-dessous ) et le fichier /boot/config.txt
Je ne comprends pas, quelqu'un peut-il m'aider?
Merci d'avance.

Voici le fichier recalbox.conf:

updates.enabled=1

default : stable ; set to unstable to get the next version currently beeing tested. set to nightly at your own risk to get the developpment version.

updates.type=stable

------------ H - HERE IT IS - GLOBAL EMULATOR CONFIGURATION ------------

The global value will be used for all emulators, exept if the value

is redifined 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=CEA 5 HDMI

Shader set

Automatically select shaders for all systems

## (none, retro, scanlines)
global.shaderset=none

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=auto

Set smooth for all emulators (0,1)

global.smooth=1

Set rewind for all emulators (0,1)

global.rewind=1

Set autosave/load savestate for all emulators (0,1)

global.autosave=1

Enable retroarchievements (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 5 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=libretro

If you do not want recalboxOS to generate the configuration for the emulator :

;snes.configfile=/path/to/my/configfile.cfg

Default cores for RPi2

snes.core=snes9x_next
gba.core=mgba
mame.core=mame078
nes.core=fceunext

The rewind option is deactivated by default on these unsupported cores (don't edit please)

virtualboy.rewind=0
sega32x.rewind=0
segacd.rewind=0
psx.rewind=0
fbalibretro.rewind=0
vectrex.rewind=0

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

global.integerscale=1
