Displayport adapator blinking/flashing RESOLVED

[Dr Lodge]

I've read about quite a few people having problems with their displayport adaptors when running 3 monitors or Eyefinity from their 5800 series GPUs. I had the same problem but have resolved it.

The syptom was an irregular but frequent blinking of the display when playing games, videos or other highly intensive graphical use. Emailed overclockers with the problem and they suggested upgrading the GPU BIOS (which I did), and also to check I had a dual link cable. What's that? I asked myself. Well, the DVI cable I was using didn't have all the pins, it was a single link cable. So ordered a dual link cable and VOILA!!! No more problems, video and COD run perfectly.

Thanks to Dean Hillier @ overlclockers for his advice, I never would have figured that out on my own.

I had it as well, did some Googlaing and found it was the GFX card BIOS needed flashing, I emailed Sapphire and they sent me an email within 24hrs with the instructions, happy days !!

As far as im aware, Sapphire and XFX are the only ones that have released BIOS updates to resolve this issue so far.

Its to do with not enough voltage getting to the output on the DisplayPort that's what is causing the flickering on and off.

Mines works excellent now with the BIOS flashed and only took 5 minutes to do, after I plucked up the courage to do it

Sapphire said if i used there BIOS update it was covered under warranty.
