There's a whole host of settings you can apply in your /boot/config.txt to
set the monitor to it's native mode.
For example, for 1680x1050, according to:
http://elinux.org/RPiconfig#Video_mode_options
The /boot/config.txt entry *should* give you native resolution ~
hdmi_drive=1 # Output HDMI sound
hdmi_group=2 # DMT (monitor, !TV) mode
hdmi_mode=58 # 1680x1050 60Hz
(maybe you need to disable overscan too, I don't remember (disable_overscan=1)).
That said, my (old) TV is natively 1366x768 and no mode resulted in a
working display.
Another non-interesting fact is that this TV (an old samsung) outputs a
rather sub-optimal range of
sizes for the EDID information, saying the best mode to drive it is
1280x720p. I guess this is correct
IFF one limits oneself to "CEA" display sizes.
I previously had this TV at native resolution on mythtv (on a PC), and am
still investigating converting a modeline into a config.txt entry. For the
moment I switched to an old PC monitor.
