My dual monitor (BenQ) is black after updatet to 8.1.
I has tryed to deinstall and install the amd driver software or under safe mode deinstall the windows default driver. Really nothing helps.
I think the problem is Windows and not the graphic driver. Because a have a another BenQ Monitor for testing if the old plugged one is damaged but the monitor is also black.
Here some infos about my system:
Windows 8.1 Pro (since last week updated)
-- Graphic Card
AMD Radeon HD 7900 (lastest AMD 13.11 Beta 9.4 installed)
The new graphics driver of amd are ready to download under http://support.amd.com/en-us/kb-articles/Pages/latest-c...
but it's not solved my "black screen problem".
22" Samsung Syncmaster 2233BW (primary)
19" BenQ FP937s (second)
The actual state that the 19" monitor get signal (the led near the powerbutton lights green look on the image) but the whole display is black.
Both monitors are plugged by DVI cables. With VGA cable is'nt possible to detect the 2nd monitor.
Under Device-Manager is the second monitor called "PnP-Monitor Standard" and in the resolution manager of windows they called by name "BenQ FP937s" also in Catalyst Control Center.
If i reanimate my monitor. BenQ logo shows - fade out - desktop appear (low brightness but seeing task and background-image) and after 2 seconds its complete black.
Has someone the same problem and a solution?
