I recently changed from a GTX 770 to a Radeon 7990 and am having issues with using my tv as a secondary display. I'll explain how the setup was with the 770, which I did not configure at all. It's just how it worked and I would like it to be the same with the new gpu.
GTX 770 - Monitor is hooked up with dvi. TV is hooked up with hdmi. Monitor is always primary, until the tv is turned on. At that point the tv becomes the primary monitor. Also, the tv's speakers take over as the primary sound device. This is important because I use a sound bar with sub for the tv. When the tv is turned off, the monitor goes back to being the primary.
7990 - Monitor is hooked up with dvi. Tv is hooked up to the gpu using a minidisplay port to hdmi adapter as the 7990 only has 1 dvi and 4 mini displayports. The tv is not always remembered as the second monitor. When the tv is turned on and recognized it is secondary. Primary sound is the pc speakers. Must manually change primary display and sound to tv. When shutting down pc and restarting, the tv is not recognized. Need to unplug minidisplay port and plug back in to make work.
I went through CCC and I did not see (or I'm overlooking) any way to make this similar to how my 770 acted. I'm hoping someone can point me in the right direction to make this work! Thank you~
