Hi guys,

Both of my monitors can go black and come back in a few seconds. This has happened several times in the last few months.

The driver does not crash when it happens. I suspect that this might be a cable issue. I have a really awful no-brand HDMI-DVI cable that I use to connect to one of my monitors. The cable is about 3 metres in length. Can a cable cause this?

I would disconnect the cable to test whether it still happens, but it happens so rarely that there would be no way for me to know if it is still happening.
