Help editing a .inf file to force 1600 x 900 resolution
Hey all,
I just got a new external monitor for my laptop and I'm having trouble making it display its native 1600x900 resolution. No problem with the 60 hz though. Some more details on my components are below. I tried about everything I could find to fix the issue. No driver updates worked, couldn't find any bios updates, I went through the troubleshooting guide on Intel's website, I checked the EDID and that looks fine (the native resolution is listed in it). I tried using the steps in this thread to no avail. When I loaded the EDID in pheonix the correct resolution and frequency showed up. So from what I have read, the only option I have left at this point is to try to edit the .inf file for my video driver. I found what I believe is the correct driver inf file based on what I've seen in a couple of other forums. It never lists 1600x900 but there are other higher resolutions so I think the card is fully capable of displaying 1600x900. Hence, I believe that the problem is there. However, I am new to this so please let me know if my logic is flawed. I need help figuring out what exactly to edit in the .inf since I haven't found an example exactly like mine. I know how to update the driver after the .inf is edited, I just don't know what to edit. The lines I suspect are below, and the entire file is attached if you find it useful. From what I have read, I should just be able to type in the new resolution somewhere and make a couple of small changes but again, I could be wrong. Thanks in advance for your help!
System info:
Computer Model: Toshiba Satellite A205-S5880
Operating system: Windows 7 Ultimate 32 bit
Monitor: LG W2040
Video Card: Intel Mobile 965 chipset
The file path for the .inf is:
C:/Windows/System32/DriverStore/FileRepository/nv_lh.inf_x86_nuetral_bbe628dbdd6fce25/nv_LH.inf
Suspect lines, they are approx half way down in the file. My guess is that I either need to add something in at the top section of this since it seems like its declaring resolutions there, or something in one of the long lines that list a bunch of resolutions:
