Sorry if this is the wrong place. I am posting here about  Bug #23408
(the duplicate of this Bug #27667) because I also have a Sony SDM-M51
that was detected as 'Unknown' monitor... and only allowed 800x600 at
first.

Eventually it started working.

I have an eeepc 701 4g laptop that it is plugged into, running Ubuntu
9.04, with 1024x768 on the sony and 640x400 on the laptop.

I am not sure exactly how I got it to work, but i think rebooting was
the key. I had tried dpkg-reconfigure xserver-xorg , ddcprobe, randr,
xresprobe, and even I shut down X and did Xorg -config from textmode
(but threw away the resulting config file and did not use it since it
had nothing about monitors in it). I didn't really change anything with
those programs. Again I think maybe all I had to do was reboot.

Here is /etc/X11/xorg.conf

Section "Monitor"
	Identifier	"Configured Monitor"
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Monitor		"Configured Monitor"
	Device		"Configured Video Device"
	SubSection "Display"
		Virtual	1744 768
	EndSubSection
EndSection

Section "Device"
	Identifier	"Configured Video Device"
EndSection

Attached is Xorg.0.log

As far as xrandr goes.. it is funny. Before my reboot, xrandr just
showed 800x600 and 640x480 for the Sony monitor.  But now, it shows:

VGA connected 1024x768+0+0 (normal left inverted right x axis y axis) 311mm x 234mm
   1360x768       59.8  
   1024x768       60.0* 
   800x600        60.3  
   640x480        59.9  
LVDS connected 640x400+1024+0 (normal left inverted right x axis y axis) 0mm x 0mm
   800x480        60.0 +
   640x480        85.0     72.8     75.0     59.9  
   720x400        85.0  
   640x400        85.1* 
   640x350        85.1  

Thank you very much and I hope this helps somebody.
