Here's the second part:
I've installed the 16.5.1 Radeon video drivers. The video card has two DVI and one DisplayPort output. Two of the displays are plugged into the DVI ports, and the third is plugged into the DisplayPort output with a DisplayPort to DVI cable.
The computer is "seeing" all three displays, as they show up in the Radeon Settings software, all properly identified. However, I cannot get any video signal to the display on the DisplayPort output.
When I plug in the DisplayPort display, the Radeon settings software "sees" three displays in the listing, but when I try to arrange the displays in Eyefinity, the diagram shows one standard display and a second one that is twice as wide as it should be. If I enable that setup, windows will open in the portion of the wide display that I can't see, and I usually have to use Task Manager to close them.
How do I resolve this problem so I can use all three displays and get them arranged properly?
By the way, the offensive word was the one missing in this nursery rhyme:
____ be nimble,
____ be quick,
____ jump over the candlestick.
