The integrated GPU inside your APU has reached peak optimisation and been moved to legacy status, there will not be any further driver updates for your product. More information available here. If it is indeed a bug in the drivers then it is not going to get fixed. As you confirmed it works using HDMI, i would recommend to keep using that.
Thanks for the link, I'll give the beta a try when time permits, what I'll do is clone a spare drive to try updating the drivers.
I've not tried Acronis cloning on HDMI.... another thing to try, I don't know why I didn't try it.
If it's only Acronis that is affected I learned that it could be a bug in the software - but I had it when installing Win 7, it got to the installation stage where you typed in the details.... meaning it can't be the drivers since they are NOT installed, I'll post back with the results in the next day or so.
