I have i5 8400 with z370m-d3h, I have installed win 10pro x64 , there is already some "microsoft basic display adapter" is installed as "intel(R) SKL/KBL Mobile desktop" by windows installation.
Now as mentioned on intel website as well as on Product (processor) packing, my processor does have uhd graphics 630, but i cannot seems to install it in my pc, i downloaded latest driver (15.60) from intel website but when i try to install it says that "supported hardware is not found for this driver" something like that, also i have tried updating online the display drivers from device manager of my pc but it says " Microsoft display adapter drivers are upto date" please help.
