J'ai trouvé !!! Après de laborieuses recherches et des essais dans tous les sens, ça fonctionne parfaitement. Comme je suis sûr que je ne suis pas le seul, voici mes deux fichiers !
Bonne journée à tous.

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
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=CEA 1 HDMI
n64.videomode=CEA 4 HDMI

If you are using a CRT screen, please change the setting above with this one : n64.videomode=default Dreamcast emulator Like N64, such a CPU intensive emulator needs a small resolution Consider DMT 4 HDMI (640480) or DMT 9 HDMI (800600). If you have a black screen on dreamcast, try DMT 9 HDMI here

dreamcast.videomode=DMT 4 HDMI

Ok , merci pour ton aide voljega

Je viens de trouver et c’était tout bête ...
voila ce qui arrive quand on ne veut pas prendre la peine de lire les tutos ..lol
je m'obstinais a modifier le fichier ;
/recalbox/share_init/system/recalbox.conf ...

alors que c'etait ;
/recalbox/share/system/recalbox.conf

Merci encore

et mon vieux scanline slg3000 fonctionne !! cool

Navré pour toi
@vreno8 tu devrais peut-être utiliser la version stable...

@oyyodams Merci de ta réponse, j'ai booté sur Libreelec et j'avais le même soucis.

Et au passage quand la résolution est en 720p ou 1020p max (je crois je me souviens plus) j'ai strictement aucunes coupures.

ça fait que je suppose que y'a pas assez de power dans l'adaptateur...

ça me saoule de devoir en racheter un autre alors que pourtant il arrive à transmettre du 1080p :/

@ubik éventuellement teste l'image de la beta du 3b+. Tu peux faire tpurner ta sd entre tes pi3, quelle que soit leur version

@barto28 Integer scale était bien a la source de mon soucis ...

Starfox 2 est LE jeu a éviter pour tester car c'est en fait simplement l'intro qui n'est pas fullscreen.

Tout est désormais OK merci infiniment Substring.

@jdpt93
yo tuve ese problema con una net pedorra q le puse batocera y cuando voy a la configuraciones me daba la opcion de elegir la salida vga auxiliar y con un convertidor de vga a hdmi y lo usaba con una tv por hdmi y despues de unos dias como magia esa opcion desaparecio, solo daba video por la pantalla de la net, cuando voy a las opciones de video para cambiar la salida nuevamente a vga solo te permitia ponerlo en automatico o una opcion q decia LVS1 o algo asi q no servia para nada porq no hacia nada basicamente.. lo q hice fue al encender la net bajo la tapa y automaticamente empieza a dar video por la salida vga nuevamente y cuando enciende voy a las opciones de video y guala aparece otra vez la opcion de elegir la salida vga auxiliar cabe mensionar q fue batocera no recalbox pero como nadie dio una solucion a este tema y veo q es viejo ya porai esta data le sirve a alguien

@chabayo

Thanks to all the thread I was able to do it
My machine is a laptop and was connected to a second screen via display port
So I have not modified the .xinicrt since I didn't find it but I manually ran the following

DISPLAY=:0 xrandr --listmonitors
Then I had two connected monitors
eDP-1
And DP-1
So I did DISPLAY=:0 xrandr --output eDP1 --off
And the laptop screen went black
After that I did DISPLAY=:0 xrandr --output DP-1 primary
And then I clicked escape on the laptop and I was back in the main screen displayed on the tv

Thank you so much for your investigation and output

Probably you should try first if there's any output from VGA only (no HDMI adapter). Maybe with a monitor or other tv if you can.

Also, try to stop ES via SSH with "/etc/init.d/S31emulatiostation stop" and start ES with "startx". See the verbose if there's any info about resolution or something.

@idarius
bonne nouvelle ca fonctionne impecablement avec un legé sintillement
j'ai utilisé "720x576@25i qui d'apres le database est une resolution en pal le ntsc c'est moyen meilleurs resultat la dessus bien meilleurs que tout ce que je pouvais esperé ca rachette le convertisseur.
Je vais malgres tout tester d'autre chose.
en revanche je ne comprend pas la res 320x240 60 qui dans le document est indiqué etre 31khz alors je comprend pas je suis pas expert j'ai simplement voulus voir si je pouvais copier la res de sorti du convertisseur qui est en pal ou ntsf du coup ca fonctionne ARCHI BIEN je suis trop dosé
@Substring pour les switch res il semblerais que ce soit bon si je regle sur 1:1 c'est nikel en revanche emulation station est completement decalé hard core avec le theme comics book meme si les jeux eux en ratio 1:1 sont centré a la perfection au pire je ferais une petite photo pour illustré.

Edité : J'ai parlé trop vite je vais devoir gerer les resolution des emu je pense devoir le faire au cas par cas je pense en revanche je sais pas comment reglé le probleme d'emulation station

Donc se soir c'est productif

Ok cool, devant la profusion de modèles existants et de témoignages du genre "le mien fonctionne" et "celui-ci est une grosse m#rd#" c'est cool d'avoir un modèle fiable.

Mais je n'ai pas dit mon dernier mot concernant le dual boot, je pense aussi qu'à force de tests de configurations j'y arriverai.
Et à force de me renseigner, aussi, car je suis partit un peu trop confiant sur un sujet que je suis bien loin de maîtriser.

J'avance sur mon projet de borne, j'enrage de devoir attendre encore une bonne quinzaine pour recevoir l'électronique (convertisseur VGA=>LVDS et inverter pour le rétroéclairage) qui va avec ma dalle de 12". Chez les chinois c'est moins cher mais quand on est pressé, c'est long.

Je ferai un sujet complet avec plein de photos.

En tout cas je te remercie encore pour tous tes conseils et ton temps passé.

Hi there, lets dig this up.

So I tried and I tried. I have a special situvation though as I use retrotink with vga out. So I want to use 240p@120hz but ES do not look good at 240p. So I thought the above info would help
(here it is in english btw: https://github.com/recalbox/recalbox-os/wiki/Connect-your-recalbox-to-a-CRT-with-HDMI-(EN) )
but no. Im also runing recalbox from a usb drive as my sd card is to small for all games.

So i edited the conf(usb) and the config(SD) on the usb and sd card. But no, ES would still use the the hdmi timings listed in the config file. What am I Doing wrong here? is it because im using a usb? and what are the folder for with a . in front of them. I know rgb-pi had this done so I know it can work, yes I asked him, wont help, cant blame him though being that retrotink is a competing product.

@ironic said in Acheter Cable VGA to Scart ?:

Non, oublie cette solution ;)
C'est juste un "duplicateur" de port.

Merci Ironic

Finalement je vais créer mon câble pour le VGA666 pour un premier test, j'ai aussi un HDMI2VGA
et apparement ce câble fonctionne pour HDMI2VGA et VGA666, ça c'est vraiment un plus aussi.

Pour le RGB-PI c'est vrai que c'est top quand même, juste un câble et hop ça fonctionne ^^
Il y aussi le Pi2scart qui au top au niveau conception pour moi, bref tout ça pour dire qu'aujourd'hui nous avons le choix grâce à des passionnés, un grand merci à eux.

@mustanguy ca pourrait venir du pi oui

@kakachagas via SSH digita tvservice -m e cole aqui novamente.
qual a versão do teu recalbox? 4.0.2 ou 4.1?

Merci de la suggestion, malheureuseent, déjà testé.

Une des 2 péritel n'affiche rien (on voit que quelque chose tente de s'afficher, mais rien n'apparait) Celle qui affiche quelque chose donne le résultat de la vidéo
