hd7990 with a a10 770 apu.. my graphic prioritizes the apu. i cant see why it only uses the r7 graphics .I run both my monitors through my hd 7900 it displays all in open hardware monitor ok ,also in the crossfire and ati suite .but is just not working a well as did without the dedicated card at all
my pc is a asus a88xm-plus
4x4gb vengence ram
amd a10 7700k apu r7
gigabyte hd7900
850 watt psu
windows 8.1

Because the video card is too strong for what you have or the its not supported. Get a new card like a r9 270 thats less demanding.

Hope it helps
