Là c'est mieux !
 
Ton souci est un souci au niveau des drivers graphiques AMD.
Essaye de les réinstaller avec la dernière version.
 
Regarde aussi si ton système est intègre avec la commande sfc /scannow en mode admin

super, merci j'ai normalement la derniere version
19.12.1

je viens de voir que le 19.12.1 est le driver optionel, le recommandé est le 19.9.2.
je vais desinstaller tout les drivers radeo et recommencer avec celui queje viens de prendre

je suis revenu a ma config normale, avec les drivers recommandés plus de soucis,
je vais tester avec le nouvel écran seul..
