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.
