Issues with 1920x1080p resolution on 945GM (GMA950)

Hi. I have a question about connecting my laptop to my external lcd (1920x1080p). When the laptop is connected to the display, I get an image on the lcd whenI boot upbut the image disappears shortly after the windows log-in screen appears. After that, I cannot get any images on my external lcdbut I do get an image on the laptop screen. I suspect it may be an issue wih the Intel GMA 950 so want to post here. I did the mon.info thing but don't know how to get the EDID as well as how to make changes to the inf file. Can someone please let me know the EDID and give me a detailed descriptioin of what to doin theinf fileas well as which inf file I have to change. I've been struggling with this for weeks so any help would bevery much appreciated. Many thanks in advance! Below is my info.
