Just got a Dell XPS 8910. The integrated graphics card is an Intel HD Graphics 530. The discrete graphics card is an AMD Radeon RX 480 with 8gb of memory.

 

When I connect a monitor using the HDMI connector for the integrated card, all works well. When I switch the cable to the HDMI connector for the Radeon, the screen displays a mishmash of broken colors with content being barely discernible. The system tray has a "Radeon Settings" icon, but clicking on it while connected to the integrated card shows an error dialog box indicating that I need to connect to a Radeon card first. But I can't see the screen well enough when the Radeon card is connected to tell what I'm clicking on.

 

Any assistance will be greatly appreciated.

 

Thanks.

Is this a brand new system? The obvious suspicion is either the video card is faulty, or has been dislodged in transit and is not seated properly in the slot.

It's brand new. I'm going to try to re-seat the card this evening and see what happens. Thanks for the help.

Tried twice re-seating the card to no avail. Calling Dell in the morning.
