HDMI fonctionne en mode sans échec, mais pas grand-chose d'autre

J'ai ma carte branchée sur mon moniteur en tant qu'entrée HDMI. Je peux accéder au bureau Raspbian en décommentant le "hdmi_safe = 1" dans config.txt. Cependant, j'aimerais travailler dans une résolution qui ne me fait pas saigner, alors j'ai essayé ces derniers jours de trouver les paramètres corrects dans le config.txt, et j'ai à peu près abandonné. Toute aide est la bienvenue. J'ai essayé plusieurs modes, mais peu importe ce que j'essaie, je n'obtiens aucune image et ce qui suit de tvservice -s:

pi@raspberrypi ~ $ /opt/vc/bin/tvservice -s
state: HPD low|HDMI off|NTSC mode|composite CP off (0x140001), 720x480 @ 60Hz, interlaced

Quelles mesures dois-je prendre pour résoudre ce problème? Merci d'avance. Le moniteur en question est un Acer H243HX.

Voici mes résultats pour les tests CEA:

J'ai un vieux (au moins 15 ans) TV / moniteur Sharp Aquos LC-19A1E et un nouveau Raspberry Pi de 512 Mo de révision B. Avec l'original config.txt, il est venu avec un écran 1080i 60Hz. La résolution d'écran dans LXDE a dit quelque chose comme 1860x ??? (oublié.) C'était bien au-dessus de la résolution maximale décrite dans le manuel de mon téléviseur (1366x768).

Il a donc essayé d'éditer config.txt:

hdmi_group=2

et

hdmi_mode=81

aucun effet.

Ensuite, j'ai ajouté cette commande en première ligne config.txt

hdmi_ignore_edid=0xa5000080

Et voila, ça marche comme un charme. Résolution native et une vue nette sur ma télévision.

En savoir plus config.txtsur http://elinux.org/RPiconfig

Comme le suggère @Iamyrus, mettez-le hdmi_ignore_edid=0xa5000080dans votre /boot/config.txtfichier.

Cependant, étant donné que le moniteur Acer H243HX est natif 1920x1080 et que le mode CEA 5 est répertorié lorsque vous modifiez le bloc EDID de votre écran, je recommanderais de définir les paramètres suivants dans votre /boot/config.txt:

hdmi_group=1
hdmi_mode=16

Vous pouvez également tester cela en plaçant simplement hdmi_ignore_edidvotre fichier config.txt puis en exécutant:

/opt/vc/bin/tvservice -m "CEA 16"

Selon vos informations EDID, CEA 16 est:

HDMI:EDID found CEA format: code 16, 1920x1080p @ 60Hz

Essayez avec config_hdmi_boost = 4 dans config.txt
