Raspberry Pi connected to monitor displays in low resolution - Raspberry Pi Forums

-

i have pi connected dvi monitor 1600x900. when connected, pi outputs video @ 640x480. running

code: select all

tvservice -s
command tells me running dvi dmt 640 480 @ 60hz. running

code: select all

tvservice -m dmt
tells me has output available, , running

code: select all

tvservice -m cea
list 2 options, 720p , 1080p, though monitor doesn't support 1080p. additionally, trying dump edid file fails, telling me

code: select all

nothing written!

your monitor not support reading edid. hardware fault, dodgy cable, or cheap monitor doesn't follow standards.

can work around this. see http://elinux.org/rpiconfig.

unfortunately 1600x900 not standard (dmt) resolution. may possible custom hdmi mode, without edid there's no clues timings expects. i'd try (in config.txt)

hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=46

if fails have try other values of hdmi_mode link.
