PROCESSOR: AMD FX-8150 Eight-Core Processor

GRAPHICS CARD: AMD Radeon HD 7970 1100MHz Core 1500 Mhz Memory 3072 MBytes GDDR5


  • DVI-D (x1)
  • HDMI (x1)
  • Mini DisplayPort (x2)

OS: Windows 7 64bit



I need help setting up a four-monitors. I have:

  • One Shimian monitor plugged in via a  DVI-D to DVI-D cable.
  • One Asus VS238H monitor plugged in via a HDMI to HDMI cable.
  • Two Asus VC239H monitors plugged in via a HDMI to Mini DisplayPort cable.


All four monitors are recognized by windows, however two remain disabled (screenshot labeled 'recognizedexample'). I can enable any combination of two monitors but cannot enable any more than two at a time. When I try I receive an error message (screenshot labeled 'errormsg').


How do I enable all four monitors so that I can extend the display to all of them? I have the latest AMD Radeon Control Center software which has a feature called Eyefinity if that helps. If you need to know how they are physically arranged in the world it is in a 2x2 grid pattern.

I would suggest a total uninstall of the drivers and then a reinstall with the latest good version.


First, download the latest AMD drivers

Then, download this: Wagnard's Display Driver Uninstaller - this is a GPU driver cleaner, it will definitely remove your GPU drivers, unlike official uninstallers. Note: There are some deceptive ads on the forum page.


  • Run Wagnard's DDU - it may create a number of files in the same directory, like a .zip file, so you may have to run it in its own folder
  • Run the application, "DDU.exe" I believe is the name
  • Select the "best option", Safe Mode and Reboot
  • After the computer reboots to safe mode, run DDU if it does not open automatically
  • Choose the "best option", clean install and reboot I think it is called
  • After restarting install the AMD driver you downloaded first
  • Restart if prompted
