That is a little strange. If you did the .inf mod correctly then you should be able to change your settings. What is displayed under Display Adapters in your Device Manager? I'm assuming you have the 60hz panel so you should see the Intel 4000 and 770M listed. 

Also install GPU-Z and see if your 770M is shown correctly there with all the device information (vBIOS version. driver version, etc)

When you inserted the hardware ID line into the .inf did you also add the String for the 770M and the bottom of the .inf file?

Here is my Device manager, gpu-z, and display adapter information

I did add the string if im not mistaken

Hi @MattyB!

I use M17xR4 - GTX 770M - i7 3630QM @ 2.40GHz - 16GB 1600MHz

I use A15 BIOS

I mod the nvdmi.inf to add support for the 770M, i managed to installed it, but i'm having difficulties to use it as default graphic card.

Whenever i try to open the nvdia control panel, it shows error message "NVIDIA Display Settings are not available, You are not currently using a display attached to an NVDIA GPU."

WIll you be kind to guide me the correct step please? I think i didn't do it properly

Thank you
