Windows 8 x64
ATi 6870 --DVI out to main monitor
HDMI out to AV receiver then HDTV
Ok my main monitor is set to main display but is being identify as 2 by windows 8 when up and running.
If my AV amp and hdtv off then turn on my pc on my main monitor the screen is blank (no signal) ill have to turn the amp on to get the screen to work. sometimes if i turn the amp back off the display turns off
if the main display working ,amp on and hdtv displaying extended display everything fine then i change input on av amp my main display goes blank. it annoying if i wanna watch Sky tv on my hdtv but have the sound through my av amp (via optic) and have my pc on. only solution is plugging the hdmi lead out the 6870
