HD7970 - DisplayLink Failure - No Display

If you look on my thread history on forums you will see that I only ask for help about the issues I get with AMD. I am going to spare you my hatred towards this company and the cry so let's get to the point.

Some time ago, I have finally figured out why all games were crashing - the issue was my sound card. Somehow it wasn't happy in my system so I sold it to a friend, where it works perfect. After about two weeks of Corssair's happy PC gaming, AMD came to him and once again made his life even more miserable.

DisplayLink Failure. - GREAT !
Basically any monitor that is connected to the GPU with a DisplayLink does not display picture.

I run three Dell U2312HM monitors in Eyefinity. They are connected as follows:
1.DVI; 2. HDMI to DVI; 3. DisplayPort.

Two weeks ago one monitor randomly went off, and since then it never came back again. I was trying to figure out what was the issue, if it is the monitor itself, if it's the card, the display port maybe, or the cable.

  1. I bought some new cables, no result.
  2. I have tried running the monitor on its own, without other two monitors connected - no result.
  3. I have tried installing cards in different PCI slots, I ran them separately and together as well. BOTH cards have FAILED to display picture on ALL THREE monitors, separately and together.
  4. Clearing CMOS didn't help.
  5. I have reinstalled drivers, I also have used ATiMAN uninstaller.

Basically whatever I do, nothing works.
I wish I never went with option for homeless people - AMD.

Any help? Thank you so much in advance...

I followed your advice step by step but same result, no picture and DisplayLink Failure window.

Keep in mind that monitors I am using have DisplayPorts built in, where is no need for an adapter. I was using StarTech cable, which seemed quite solid, however after rotating the monitor a few good times, it kept losing signal, so I had to move it, or "press down" the cable down it order to bring the picture back. Now it doesn't display anything, I assume it broke.

The cables I bought now are some cheap crap, once I opened them there was barely anything inside so I need to find cables I was using previously.

And I don't believe it's hardware issue as:
none of the ports in both cards will give to any monitors.
 
Sorry I took a while to reply, work keeps me busy.

When the monitor is connected via the DisplayPort, it immediately goes to "Sleep Mode" no matter what. So when the computer is being switched on, not even BIOS/POST screen will display. My brother should have a GPU with a DisplayPort, I will give it a shot and see if it works, and I will let you know soon.

Thank you so far.
