So, Just installed Windows 7 on my T60 with intel 950 chipset and now I cannot get an external monitor to work. The computer detects it in device manager but the external screen remains blank.

Now, I realise there are lots of people that think they have faulty motherboards or that its a graphics chip fault, but I know its not...becuase If I put in my old hard drive (also with Windows 7 pro) it works fine.

I used exactly the same method on both drives:

1. instal Windows.

2. Use windows update to bring the OS up to date.

3. Download Lenovo System Update & apply all updates

Obviously the older drive (about 1 year) has been updating itself reguarly using Windows update. But thats the only difference. I also tried downloading just the chipset drivers but it makes no difference. It cant be a bios setting as one installation works fine.
