Windows 8 not displaying second monitor on boot

I upgraded to Windows 8 a little while ago, and its mostly working great. The only problem I'm having (apart from something in Windows Update bricking my system whenever I update and having to do a system restore, but I've just turned that off for now) is that every single time I boot my second monitor just shows a black screen. The system POST information appears, followed by the Windows 8 loading screen, but as soon as I hit the unlock screen it just goes blank. Not switching off, the backlight is still going, but displaying a blank screen. Device manager and desktop properties and the Catalyst control center all still see it and think its working fine, but nothing. I restart and it comes up straight away. Every single time. I'm running the exact same hardware as I was on 7, with the latest AMD drivers so to me it has to be Windows 8 as the culprit. Any ideas?

Hi Danlevan,

Thank you for choosing Windows 8 and welcome to Microsoft Community Forums.

I see that the dual second monitor is not working in the dual monitor set up.

Thanks for the reply Karthik.

I'd gone through all that, but it turns out that it must have been a driver issue, as the most recent AMD beta driver has fixed the problem.

As for the system restores, something in Windows update was causing the system to blue screen immediately on boot, and wouldn't load into the OS or even safe mode. After a couple of tries Windows was automatically going into recovery mode. It's currently showing 37 items in there, and as I haven't the foggiest which of them was causing it, I'm somewhat reluctant to go through them one by one at the moment. It's possible it was tied to the driver issue, in which case it too might have fixed itself.

I must try that.   Thanks for the tip.

 

FWIW I had been assuming that what you were describing was normal.   E.g. if I want to see both screens at the same resolution as the primary I need to use Win-P, CursorUp, Enter.   But then it is just duplicated and looks terrible in the wide-screen monitor anyway.
