Ive got an LCD screen whose native resolution is 1440x900 yet i can
only get Wheezy to display 1024x768. No higher resolution is listed
in System Settings. How do I enable a higher resolution please?
This is probably an issue of your graphics card rather than the
display itself. Please furnish information about what graphics card
is in your system. You can use the output of the lspci command to
find this.

I also have an Intel 945GM graphics chip in my laptop. Works fine for
me on Wheezy. Sounds like you're running the VESA (generic) graphics
driver instead of the Intel one. Do you have xserver-xorg-video-intel
installed? Also, if you have an /etc/X11/xorg.conf file, rename it to
something else, and try restarting X.
Hope this helps!

yes the xserver-xorg-video-intel package is installed. how do i check
which driver is actually being used? one strange thing is that the
kernel is printing out the following to the console, not sure what it
means, could it be a fault with the controller board in the LCD?

You can tell by looking in /var/log/Xorg.0.log. If after looking at the
log file, the problem isn't readily apparent, post the contents here,
and someone should be able to figure out what's wrong.

I've had issues with EDID in the past when using too long monitor cable.
Try using a short and known-good cable. If this doesn't work either you
can try replacing/fixing the monitor (it helps if it is still under
warranty) or just hardcode the monitor capabilities in xorg.conf (you
will need some specs out of the user manual or the internet).
Hope this helps,
Andrei

The pertinent contents of the log seem to be as follows. Im not sure how
it works. It seems to probe the monitor to see what resolutions it
supports. Should the controller board in the LCD therefore have a list
of supported resolutions on it which it reports back to X?
Im using a controller board from LCDparts.net They claim to have
programmed it for this screen and that if it wasnt programmed correctly
I wouldnt get any image at all and therefore its an OS problem but Im
not convinced.
Thanks for all your help so far!

EDID is the mechanism by which the display notifies the Gfx Card
of it's Capabilities(Resolution etc).
The message above may either be caused by your display not supplying
this information, or it is querying the wrong output. VGA instead of
DVI. In the latter case, it may not be significant at all.

What's the output of "xrandr"?
You can try to manually add the desired resolution from there (using
xrandr). Here is a good doc, although it can be a bit oudated, YMMV:
