Had problems with this now for about 8 months now, at first I thought it was just a fault on my monitor but it looks like it down to how AMD drivers are detecting it.
Basically, I have to turn my monitor off/on numerous times before AMD recognises and initiates the display device driver, it doesn't show me the desktop until it has detected the digital display - tried replacing the power cable and the DVI cable and was considering now buying a new monitor but..
As a last throw of the dice, I uninstalled AMD drivers to try out the new beta drivers.. but before installing the new driver I tested powering my monitor on/off with windows drivers.. and my monitor powers up straight away no problem.
So I'm wondering if this is some kind of rare issue which only happens when using my particular GPU and monitor?
24" SAMSUNG B2430L
If anyone has any ideas what could be causing this I'd really appreciate it, already lost a few hairs trying to figure this out!
