I recently purchased another monitor, so I'm now running a tri-head setup. I have 2 monitors connected to GPU0 and one to GPU1. The GPU's are both 5830's.
Whenever I'm mining, one of my monitors on GPU0 starts flickering. It appears to be snippets of the other monitor connected to GPU0. This is very strange as it doesn't happen when I plug out my monitor from GPU1.
Has anyone experienced any issues like this? Its a small bit annoying, but I'm mainly worried that I may have damaged/are doing damage to my cards.
I saw this with one of the 5770 rigs that I had setup. Later on I did a reformat and it worked fine. I would not use multiple displays and mining. Especially two monitors on 1 gpu. I can only imagine that the extra displays will just tax the system. You can leave them hooked up, but I would just make a profile for mining where only one displays.
