aliman1 Posted December 14, 2022 Share Posted December 14, 2022 Has any one had success upgrading the M17XR4 to the GTX1070 with a 1920x1080 60Hz display screen , someone was telling me that it would work through Nvidia Optimus letting the card function at slightly lower performance , is this true or do you need to use the eDP 120Hz display for this car to function properly. I bought a GTX 1070 card and modified the driver INF file. I modified the " nvdmig " INF file with the cards hardware ID and my pc's hardware ID , is that the correct INF file I need to modify or is it the " nv_dispig " INF file . I installed the driver with Driver signature enforcement Disabled and it appeared to install successfully , the GTX 1070 appears in the Device Manager and I'm able to set the GTX1070 as default card in Nvidia control panel but the system won't use the GTX1070 when i try and benchmark it . Right now I'm stumped at what to do next , I was trying to upgrade my sons laptop for Christmas but things are not working out , any help would be awesome , thank you.
