Mobo: Gigabyte GA-F2A85X-UP4BIOS version F$ (latest available)Details: The motherboard has four integrated video connectors: Displa Port, HDMI Port, DVI-D Port, and D-Sub (vga/svga) Port. The mobo manual states that the mobo will support the following "Triple-Display" configurations: D-Sub + DVI-D + HDMI (this is the config I wish to use)DVI-D HDMI + DisplayBut the manual also states the caveat, "Triple-display congurations are supported after you install motherboard drivers in in OS." However, I have already installed all of the drvers that came on the mobo driver CD. when that failed to activate the desired feature, I downloaded and installed all of the drivers for this mobo from Gigabyte's USA supprt site. Still no change.I should mention that there are no separate graphics divers for this modo, either on the CD or the website. Instead, Gigabye only provides a Chipset driver, which includes video support. But what the Chipset driver pacage actually installs for video is the AMD VISION Engine Control Center application, which only recognizes cominaions of two displays, either HDMI + Sub-D, or HDM + DVI-D, or DVI-D + Sub-D.Device Manager shows the Displa Adapter as "Radeon HD 8570D". I tried to locate Windows 8 64-bit drivers for either Radeon HD 8570D or A-series APU on AMD's website to no avail.Any advice or suggestion will be greatly appreciated. Thanks.
