Dxdiag cant detect my amd graphics card

[wishalff]

I had a lenovo g400 with intel pentium b960 2,20ghz with intel hd graphics and amd radeon HD 8570M 2GB. I had installed the latest amd driver but in the dxdiag only intel hd graphics readed but the vram was total from intel hd graphics and amd graphics (3846MB). How can i switch my graphics card into amd? I had disable the intel graphics at device manager, but there was no graphics card detected then. Help pleaseeee

in your bios setup under graphics you can set it to use one or the other, or set it to "switchable" which uses both. It sounds like it is set to only use integrated graphics right now, since the radeon is not visible in windows

DXDiag, CPUZ etc. Won't read the discrete card so it's nothing to worry about. To "possibly" read the NVidia Only, I'm Guessing that You'd have to plug in Your external monitor and set it as the Only display. Then You'd have to be either Gaming or running something in 3D and then most likely DXDiag still wouldn't read it. If You have the setting in BIOS to switchable as posted above, the NVidia will kick in when needed.
