I have a HD 6870 that has DVIx2 and HDMIx1. What I'm trying to do is run my computer monitor through the DVI and also my TV with the HDMI. I want to duplicate them except it won't work. Every time I try to either Extend or Duplicate, it says it is unable to save display settings. Can I not use both at once?
I did buy a DVI to HDMI adapter and my desktop would duplicate on both at the same time but of course I didn't have any sound on the tv since I was using DVI. I know I can buy a cable that would fix this but I'd rather spend nothing if possible
I mainly want this for watching movies and duplicating the desktop wouldn't be a big deal then, I wouldn't mind just switching displays. But I like to have my desktop on both displays sometimes when my nephew comes over and watches me play some pc games and things like that.
I've been messing around with it and I originally had my monitor in the bottom of the two DVIs, I changed it to the top one (for the hell of it) and my desktop is on my monitor and desktop. Amazing... >_> but one problem (of course)...
For some reason my monitor has a black outline about an inch thick around the whole outside even tho I'm on my max/native resolution of 1920x1080... Going to continue messing with it but incase someone has any suggestions?
