HDMI funciona no modo de segurança, mas não muito mais

Minha placa está conectada ao meu monitor como uma entrada HDMI. Posso acessar a área de trabalho Raspbian descomentando o "hdmi_safe = 1" no config.txt. No entanto, gostaria de trabalhar em uma resolução que não faça meus olhos sangrarem, por isso tenho tentado nos últimos dias encontrar as configurações corretas no config.txt, e já desisti. Qualquer ajuda seria ótimo. Eu tentei vários modos, mas não importa o que eu tente, não obtenho imagem e o seguinte em tvservice -s:

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

Que etapas eu preciso tomar para solucionar esse problema? Agradeço antecipadamente. O monitor em questão é um Acer H243HX.

Aqui estão meus resultados para o teste CEA:

Eu tenho uma TV / monitor Sharp Aquos LC-19A1E antigo (pelo menos 15 anos) e uma nova revisão de 512Mb B Raspberry Pi. Com o original config.txt, ele veio com uma tela de 1080i 60Hz. A resolução da tela no LXDE dizia algo como 1860x ??? (esqueci.) Estava muito acima da resolução máxima descrita no manual da minha TV (1366x768).

Por isso, tentou editar o config.txt:

hdmi_group=2

e

hdmi_mode=81

sem efeito.

Em seguida, adicionei este comando como primeira linha no config.txt

hdmi_ignore_edid=0xa5000080

E pronto, funciona como um encanto. Resolução nativa e uma visão nítida na minha TV.

Também mais sobre config.txtsobre http://elinux.org/RPiconfig

Como o @Iamyrus sugere, coloque hdmi_ignore_edid=0xa5000080no seu /boot/config.txtarquivo.

No entanto, como o monitor Acer H243HX é nativo de 1920 x 1080 e como o modo CEA 5 é listado quando você edita o bloco EDID do monitor, recomendo que você defina o seguinte /boot/config.txt:

hdmi_group=1
hdmi_mode=16

Você também pode testar isso colocando apenas hdmi_ignore_edidem seu config.txt e executando:

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

De acordo com a sua informação EDID, o CEA 16 é:

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

Tente com config_hdmi_boost = 4 no config.txt
