Hello,
I'm having trouble getting all 3 of my BenQ monitors to 120Hz. My GPU is a GTX 780.
Two of my monitors are connected with Dual-link DVI and one is DP-DVI.
All cables are dual-link, yet on the one connected with DP I can only get 60Hz? It doesn't list 120Hz as an option. Help is greatly appreciated!

A DP to DVI cable is not going to work. It has to be DP to Dual Link DVI-D. Most do not support Dual Link, so it is important to search for one that does.

The thing is, the cable is DVI-D Dual link, though?

The cable may be, but that does not mean the converter supports it. You are only as strong as your weakest link.

Alright, could you possibly link me an example that would work?

When it comes to these adapters, many don't work well, but this is the type of things you are looking for: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

This may or may not work: http://www.newegg.com/Product/Product.aspx?Item=9SIA0ZX...

It is not active, which I don't know if matters. It is far and away the cheapest of these types of adapters, which makes me wonder.


Wouldn't a DP-DP cable work?
Also, at the moment the DP cable I am using this: http://www.mindfactory.de/product_info.php/5-00m-DP-Ans... ?
Gratitude for your big help!

Edit: Do all of the cables need to end in Dual Link DVI-D? Do I have to get an active adapter for the DP or something, couldn't I just get a double DisplayPort 1.2 cable for my third monitor to reach 120hz?

Try a single monitor on its own with the cable. See if you can make it work.

Just because it has the pins doesn't always mean it'll support the bandwidth. I do not know about whether or not it needs to be active.

Apparently it's the cable, gives only 60Hz.
So the DP-Dual link DVI-D must not be active...
But does DP-DP support 120Hz, and could I use a cable like that with the Dual link DVI-Ds?
