I have the very same issue and I have tried to get the settings for my monitor right, tried with and without DDC. It's somewhat better now that I've changed the settings manually from information in the manual etc. In windows I could see that it was set to 59Hz wich makes it blank less than if I set it to 60Hz for example, and I've added RB but it still blanks every now and then so it seems to be something that can't be fixed by the user
