Windows – Can’t enable third monitor after upgrading from Win8 to 8.1

multiple-monitorswindows 8

I recently updated to Win 8.1 – now only 2 of my 3 monitors are working, after they were all working perfectly fine under Win 8.

I have 3 x HP E231's running on an AMD R9 280x – One of the monitors is DVI, the other two are Mini-Display Port to DVI.

In Screen Resolution or the Catalyst Control Center, every time I try to enable the third monitor it tells me I have to disable another one.. I can't find much info on the net about this problem – have checked here Windows 8.1 triple monitors – can't enable all 3 at the same time but the guy just brought an adapter – I know all three monitors were working under Win8 so why not 8.1?

Cheers

I added more 1 solution, which is:

Also works without mini Display Port, just unplug your GPU from Motherboard for some time and then re-plug it and all monitors.
