Video setup: confusion with HDMI/DVD input - Raspberry Pi Forums
i "professional" computer-user enthusiastically converted ubuntu on retirement.
raspberry pi christmas-present allow me experiment more basics of computing rather fixed os solutions microsoft , apple provide. worked fine on setup, on issue of video-configuration stuck, after reading edid, tvservice , options in config.txt.
repaired old syncmaster 206bw use monitor works fine in preferred mode of 1680x1050 dmt:

maybe "avoid_fuzzy" help, haven't been able find how works , little knowledge can dangerous thing...
have helpful suggestions how resolve?

moin,the pi defaults preferred resolution of dmt (with no sound) , can find no way change config.txt use native cea mode.
config.txt set-up pretty described in "rpiconfig - elinux.org", see:
hdmi_group=1 cea
these values valid if hdmi_group=1 (cea)
may bootloader work you.
have nice day
