    Hey all,
    I just got a new external monitor for my laptop and I'm having trouble making it display its native 1600x900 resolution. Some more details on my components are below. I tried about everything I could find to fix the issue. No driver updates worked from Toshiba or Intel, couldn't find any bios updates, I went through the troubleshooting guide on Intel's website, I checked the EDID for the monitor 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. My .inf 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 think I know how to update the driver after the .inf is edited, I just don't know what to edit. The entire .inf file is attached. 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 naturally, I could be wrong. And of course, if you have any other ideas, please speak up! 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


    My file path for the .inf is:
    C:/Windows/System32/DriverStore/FileRepository/nv_lh.inf_x86_nuetral_bbe628dbdd6fce25/nv_LH.inf

    The lines I suspect are about halfway through and are quite long. it looks like in these lines and in a block before them allowable resolutions are being declared. So I feel like I can just add mine in somewhere.

    Nevermind, I worked out my issue using this method. It looks like Toshiba actually restricted the use of 1600x900 in the bios, so I'm technically running 1598x600, but that's close enough for me.
