HDMI funziona in modalità provvisoria, ma non molto altro

Ho la mia scheda collegata al mio monitor come un ingresso HDMI. Posso accedere al desktop Raspbian decommentando "hdmi_safe = 1" in config.txt. Tuttavia, mi piacerebbe lavorare con una risoluzione che non mi fa sanguinare l'occhio, quindi ho cercato negli ultimi due giorni di trovare le impostazioni corrette nel file config.txt e ho quasi rinunciato. Qualsiasi aiuto sarebbe grande. Ho provato diverse modalità, ma qualunque cosa io provi non ottengo alcuna immagine e quanto segue da tvservice -s:

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

Quali passi devo prendere per risolvere questo problema? Grazie in anticipo. Il monitor in questione è un Acer H243HX.

Ecco i miei risultati per i test CEA:

Ho un vecchio (almeno 15 anni) Sharp Aquos LC-19A1E TV / monitor e una nuova versione da 512 Mb B Raspberry Pi. Con l'originale config.txt, è uscito uno schermo 1080i 60Hz. La risoluzione dello schermo in LXDE diceva qualcosa come 1860x ??? (dimenticato.) Era molto al di sopra della risoluzione massima descritta nel mio manuale TV (1366x768).

Quindi ha provato a modificare config.txt:

hdmi_group=2

e

hdmi_mode=81

nessun effetto.

Quindi, ho aggiunto questo comando come prima riga in config.txt

hdmi_ignore_edid=0xa5000080

E voilà, funziona come un fascino. Risoluzione nativa e una visione nitida sulla mia tv.

Altre informazioni config.txtsu http://elinux.org/RPiconfig

Come suggerisce @Iamyrus, inseriscilo hdmi_ignore_edid=0xa5000080nel tuo /boot/config.txtfile.

Tuttavia, poiché il monitor Acer H243HX è nativo 1920x1080 e poiché la modalità CEA 5 è elencata quando si modifica il blocco EDID del display, si consiglia di impostare quanto segue in /boot/config.txt:

hdmi_group=1
hdmi_mode=16

Puoi anche provare questo semplicemente inserendo hdmi_ignore_edidconfig.txt e quindi eseguendo:

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

Secondo le tue informazioni EDID, CEA 16 è:

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

Prova con config_hdmi_boost = 4 in config.txt
