I have been running with 2 monitors for a while without problems. After the latest Windows update the system no longer recognizes the second Monitor (Sony)
HP 2207 on DVI- D
Sony Bravia 48 on HDMI
Radeon HD7800 , Crimson Radeon Software 16.9.2
Windows 10 64 Bit
Desk top i7-4770 CPU 3.46 *2
When the system starts up I see the start up on both monitors. When windows starts I lose the second monitor. (Sony) It does not detect the second monitor in settings/ Device Manager..
I've tried a number of things....including removing and re-installing the ADM drivers. ( both monitors work when I disable HD7800 and run off the Intel chip (at much reduced quality)
Window P for projection does nothing.
