Will this work for 120Hz?

Hi,
I currently have an ATI HD 5850, and I'm getting a 3d 120Hz monitor.
To get 120Hz, how will I connect my monitor? I've heard 3D in HDMI only, but my monitor will only take 120Hz via Dual Link DVI? (It's a Acer GN245HQbmid). So if I get a HDMI to Dual Link DVI cable, will that provide both in one solution? I'm not looking to use it for 3D much, but having this single cable would be much easier!

You can do 1080p 3d over dual link DVI, don't worry about that.

In fact I don't think there is any dual-link dvi to HDMI 1.4 cable so that would mean you'd end up converting it to HDMI 1.3 which can't do 1080p 3d.. so don't do that ;)

So if both your videocard and monitor have dual link DVI, use that.

As a side note; HDMI 1.4 can't do 1080p at 120Hz, either. It isn't supported by the current specification so you need to use DVI Dual Link on the Acer. HDMI 1.4 is used for supporting 3D for non-PC devices that don't require the 120Hz refresh rate of active shutter glasses.
