500 Points for helping me modify Intel GPU driver!
Hey, the first person that can successfully help me to get a desired screen resolution via modifying the Intel drivers gets 500 points, I would attempt this but trying to work out HEX values is rather taxing (been a while!).
Here's the situation, we have a couple of Dell Inspiron 3100's, these have a GPU driver provided by Dell, recently the users of these computers were complaining that they're 17' screens weren't big enough, so we purchased some Dell ST2010's which have a bespoke resolution of 1600x900. The graphics cards will go as high as 1600x1200, but this doesn't work on the panels, the closest match I've been able to make is to use 1280x1024 for the time being, however the image is rather skewed/distorted.
Then I came to find this:
http://software.intel.com/en-us/articles/custom-resolutions-on-intel-graphics/ (PLEASE READ before attempting to answer this question)
However, trying to translate the DTD/EDID data is melting my brain and making me want to toss the computers / screens out of the window. I've provided a MonInfo dump from one of the Inspiron's with one of the new screens attached (check the code section below),
Here is also a screengrab from MonInfo:
I've also attached the stock GPU driver's .inf file here: ialmnt5.inf.txt
So, to re-iterate, the first person to provide me with a working (as in monitors work at 1600x900) modified .inf file is rewarded 500 points and much of my love.

Excellent! However, lacking details.

I even forced the drivers on the Win7 machine, it BSOD'ed on the logoff, but after that it seems stable now. I will keep an eye on it, if it becomes unstable I'll take an image of the XP machine and clone it onto the 7 machine.
