[Redshii34]

I have recently Bought a amd Radeon 8490 LP graphics card and I am not to sure on why its not displaying or being detected. And my desktop is a HP - Compaq dc7900 Small Form Factor I am new to PC related stuff but I kind of understand some things about pc parts but not much.

if you have igpu, could you go to bios and force the graphics output to igpu and see in device manager if the gpu is present?
