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
