I'm not sure if this has been asked, but here it goes~
I have a 5970, two DVI ports and one mini displayport.
When I hook up my two monitors with the two DVI ports, it works fine. When I attempt to connect my 50' TV to the mini displayport via an HDMI converter; my display options says "Unable to save display settings."
All monitors and TV share the same resolution of 1920x1080. Monitors are 24', and TV is 50'. I'm looking to extend my desktop onto my TV, but again, I get the above error.
