Hi I have a Asus GeForce GTX 780Ti DirectCU II 3072MB GDDR5 PCI-Express Graphics Card. It has only one hdmi port and I would like to use two screens with same image. How can I do this?

Thank you

edit: I have seen hdmi splitters but with them you can only use one screen at a time, am I correct?
 
Why not connect the other screen with a different connector (eg DVI, and use a DVI-HDMI adapter if needed) and then just duplicate the desktop via windows?
 
the two screens are 4 metres away from each other. I had a 5m hdmi cable so had a try using motherboard hdmi output but screen kept blinking. If I use dvi would it stop the screen from blinking?
 
ive just tried plugging the hdmi cable from graphics card (pc) straight to tv and it still blinks even though without trying to split image. any ideas?
 
Could be a faulty lead?

I have my monitor connected via DVI port, and have a wire buried into the wall upto my TV which connects via display port. Than I use Windows to control whether it extends or duplicates the desktop.
 
A cable that length could quite likely be a connection issue. Try moving it closer and trying a shorter cable to rule that out.
 
Use the display port or DVI for the other monitor?

That length shouldnt be a problem i have a 5m DVI to one of my monitors, a 10m HDMI to my TV and a 2m display port going to my main monitor all from the same card.
