Not a syncmaster 793s, but an Iiyama AU4831D flat panel
(1600x1200 native resolution), and an nvidia video card.
The nvidia driver insisted to drive the flat panel display at
1024x768 resolution. (Before I upgraded the hardware
an ATI Radeon 7500 card was used; the ati Xorg video driver
auto detected the correct panel size / resolution of 1600x1200
just fine).
What kind of video card are you using?

With the nvidia video card, nvidia binary driver and Iiyama AU4831D
flat panel, the solution was to add
# Work around nvidia problems with AU4831D panel
Option "ModeValidation" "NoDFPNativeResolutionCheck"
to the Screen section in /etc/X11/xorg.conf.
The Iiyama AU4831D is returning two timing modes in EDID
data (1st: 1024x768, 2nd: 1600x1200) and the nvidia driver assumes
the first one specifies the panel's native resolution and rejects
the second one "because it's bigger than the panel's native
resolution" - which is nonsense.
The ATI driver is a bit smarter, and computes the panel size as
the maximum over all resolutions returned in EDID data.
Maybe this helps, in case you're also using an nvidia video card...
