I have been attempting to run a 3 screen setup and have run into a bit of a snag. For starters I will be running to asus 24" montiors and attempting to add a vizio e420vo tv (if that is a dumb idea my apologieze..slightly a newb). That being said I will move onto my computer hardware.
I am running a asus m5a97 r2.0 motherboard:
and an AMD radeon hd7750 graphics card.
So far I have been running one of my monitors through an hdmi port on the graphics cards, and the other monitor is running through a VGA plug on the graphics card. My latest attempt was to plug the vizio in using a DP to HDMI cable.
So far my computer can see all 3 displays coming up but I am getting no signal on the vizio tv. When I click on the 3rd display (the vizio) it will not allow me to make any changes with the resolution or orientation. When I choose to extend display to this screen and press apply I get a message "unable to display settings". saying From here I am pretty much stuck with my knowledge not extending to much further.
Any help would be greatly appreciated!
