Some of the APU display lanes are shared with pcie lanes so you can only use one or the other. On your board it looks like the DP connector is using the shared lanes. The bios should disable the connectors served by those lanes when a pcie card is present, but it looks like your board is not disabling them properly. You might try a newer bios revision if one is available, or moving the discrete card to another slot, or checking to see if there are any special bios options regarding the pcie slot and display lanes.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
