Hello

I have an Optiplex 3020 with i3 processor with Intel HD Graphics 4400. I bought an rx 460 and I tested it in another pc to see if it’s working. Then I installed it in to the Optiplex and connected the display cable to the graphics card and my monitor. No power cable for the gpu is needed. But unfortunately I didn’t get any picture. Then I connected to the iGPU and in the Bios the graphics card is detected and I selected the entry. Before that it was an auto. But still no picture. Then I connected another gpu which I also know was working. But unfortunately again no picture. I don’t have any other ideas. Sorry for my bad English. My main language is German.
