I don't know 916resolution and what that does. However, it sounds to me like 
you at the basic level here is missing a modeline for 1400x1050 in your 
xorg.conf. 

Just to try to explain what I mean. This is what it looks like in mine:
myuser at mymachine:~$ more /etc/X11/xorg.conf
...
...(i am skipping non related stuff on top of the filehere)
...
Section "Screen"
        Identifier      "Default Screen"
        Device          "NVIDIA Corporation NVIDIA Default Card"
        Monitor         "SyncMaster"
        DefaultDepth    24
        SubSection "Display"
                Viewport 0 0
                Depth           24
                Modes           "1600x1200"
        EndSubSection
EndSection
...
... (there is more below but that is not relevant, i think)
...
The line starting with Modes i think is what you are looking for. I have a 
flat panel display with 1600x1200 resolution, and I am not really interesteed 
in using any other resolution, so I don't have any alternatives. However, if 
your desired screen selection is not in this list of modes, it will not be 
selectable. 

This is a "modeline" from a previous version of my xorg.conf:
Section "Screen"
...	(skipping)
	Subsection  "Display"
		... (skipping)
		Modes           "1600x1200" "1280x1024" "1280x960" "1152x864" "1
024x768" "832x624" "800x600" "720x400" "640x480"
		Endsubsection
	.... (skipping)
EndSection

With this modeline, all the listed resolutions are selectable from within the 
Kmenu>System Settings>Display>Size, Orientation and Positioning.

You will want to check that in your /etc/X11/xorg.conf the 1400x1050 is listed 
in the "modeline". (Notice there may be several sets of these for various 
colour depths, and you need it in all).

If you are not familiar with editing the xorg.conf, you can probably google up 
a tutorial somewhere, but always backup the original, and then don't try to 
rewrite all of it at once. Ask rather one too many questions than one too 
few. This file is instrumental in getting yorur graphic desktop to work, if 
it is destroyed, it can be rebuilt quite easily, but you will have to do that 
from a console login.
