Unlikely to be a monitor problem. I'm running Wheezy on another disk on
this machine without any problem. The dmesg does not report anything
unusual. Among the lines are:

  nouveau [DEVICE] chipset G86 (NV86)
  irq 48 for MSI (MSI-X)
  nouveau [DRM] failed to create encoder 0/1/0: -19
  fbcon: nouveaufb (fb0) is primary device
  [drm] Intitialized nouveau 1.1.2/ 20120801 for 0000.01.00.0 on minor 0

This configuration worked, but still in VESA mode.

I'm running fluxbox with no desktop environment. Fluxbox comes up. So I
guess the issue is that the resolution capabilities of nouveau (and
modesetting) are not being accessed even though the module is loaded. 

Thanks.
