Tente avec un autre cable et sur une autre prise peritel ou autre tv ou vcr ou vga sur un ecran vga et compare
Du N et B signifie que une partie du signal ne passe pas
Il faut trouver quelle connectique pose pb.

@iga

Yes, i did, but it's not helped.

What videomodes have you tested? What were the results?

Have you checked if the manufacturer's page mentions any other options that may be related?

@baddubaddu

Is there any way to disable or remove the core?

No, and it's not even necessary, just don't use a core if you don't like it, the presence of a core doesn't interfere with the performance of the other.

Or even to get swanstation to run without a constant stutter?

A lot of people use it and like the performance, I don't have an RPi4 and I don't have a way to test it to try to reproduce the problem you're claiming.
It seems to be a configuration issue, not a bug, but like I said, I can't test it so I'm not sure.

What version of Recalbox are you using? Did you build your Recalbox yourself, or did you buy it all ready-made, or even downloaded a ready-made image from the internet? Can you test on another memory card, a clean image without configuration, to see if the problem persists?

Le prix est intéressant surtout a une période où on a des RPI4 a quasiment le même prix par des recensé peu scrupuleux qui profitent de la pénurie, autant aller vers de type de mini PC

@aldébaran Je comprends. Tu m'a dis que I3 8100 et Gpu GT 1030 ça tournait bien ? C'est montable en mini pc comme un NUC ?

MERCI MERCI MERCI

Hello @prfabien , désolé pour la réponse tardive.

J'étais parvenu à revenir à l'affichage standard en supprimant le fichier recalbox-crt-config.txt à la racine de la partition Recalbox (à moins que ce soit recalbox-crt-option.cfg dans Recalbox\crt j'ai un doute.)

Cependant cela avait résolu le problème uniquement pour l'interface de EmulationStation, car tous les jeux avaient malgré tout conservé les paramètres de résolution optimisés pour les écrans crt.

J'ai donc fait une clean install de Recalbox 8.0.2

Le fait que l'option d'affichage standard disparaisse du menu "CRT adapter" est probablement un bug, je ne me souviens pas avoir fait d'autre manip' à part entrer et ressortir du menu.
Avec la clean install de 8.0.2, toutes les options apparaissent correctement.

@supernature2k Merci pour ta réponse, cela m'a été confirmé aussi, cela n'a rien avoir avec l'affichage.

Hi, i'm waiting my own rgbdual but for now i have enabled this update using my pi2scart.

update.type=recalboxrgbdual

50/60 Hz selection is now available, and pal games on snes are more "wider" now, but the image is a few centimeters shifted down.

On EmulationStation the image is centered, is there an option to center the image only for specific emulators?

@fneto4 About using a CRT TV via composite cable, I just answered another post with a similar situation, please check:

HDMI

Have you tested your Rpi on another TV without an adapter?
Can you test with another adapter?
Are you testing with the correct HDMI port on the RPi4?

Have you tested with another HDMI cable? There are several versions of HDMI cable, not to mention the quality of the cable...

Have you checked if it's not some setting on the TV?

HDMI converter to VGA

Signal converters usually don't bring the expected result, they don't always manage to make the ideal communication between the RPi and the TV (since they make a conversion).
A signal converter is literally like an automatic translator: sometimes the translation is so mechanical that you can't understand it even after the information is in your native language.

In short, the converter needs to correctly identify your TV's EDID, and convert that to RPi. When the converter can't even recognize the edid, the whole conversion goes bad, so one possibility you have is to force an edid configuration manually, as per the options mentioned in the official raspberry documentation:
https://www.raspberrypi.com/documentation/computers/config_txt.html#hdmi_ignore_edid

There are some users who claim that a DVI adapter works better, but I've never used it either, and there are many different makes and models, so I can't say:
https://forum.recalbox.com/topic/24295/message-hors-de-portée-écran/2

Generally speaking, video adapters are not a good idea, use them only if they are the last option. And unfortunately, we don't have a lot of user reports showing which makes and models are working, and without those user comments, we don't know either.

@zing Cara, tudo funcionando!

Muito obrigado pela atenção ao meu problema. Você foi GRANDE!
