Graphic card detected but not transmitting

[minibot7]

My card is shown on the device manager but it doesn't transmit any pictures, just blank screen. I disabled the on-board card, also installed the latest driver. Anybody got an idea?

how did you view device manager if you don't get signal from the card?
