Saga continues…
Shut down, unplugged VGA cable, booted…. Fuzzy screen again…
On a whim I hot plugged the VGA cable in – screen fixes it self!
looked at settings – they are the same…
unplugged VGA – fuzzy screen, so plugged it in.
Went back to graphics properties and set it to one display – the HDMI one. Hit apply, everything still ok. Now unplugged VGA, still good!
Rebooted with only HDMI, and it’s good!
So very strange! I need a beer!
