hdmi - dual link dvi?

[Diagro]

Hey

I see that Hdmi 1.4 is capable of 2560x1600.

Will a hdmi to duallink dvi-d cable work from a hd7990 to a hazro or catleap monitor?

Would be intresting if it does. .. as the cables are less than a tenner

IIRC its difficult to get a setup that supports HDMI 1.4 from end point to end point.

 

[Diagro]

I was under the impression that hdmi and dvi use the same signals?

Am I incorrect?

They do, but Rroff is talking about a HDMI cable that has the wiring to support 2560x1440/1600.

Worst comes to worst, that card has 2x displayport outputs, so you can just use one of those DP>DVI-DL converter boxes.

Why would you not just connect using a Dual link Dvi ? The 7990 and the monitors you have mentioned have this.

The dual link DVI seems to be faulty on the card he's bought.

Was mad?

Ah I see. You would be better getting an active DP to Dual link Dvi adapter. Will cost a few quid though. Does your display not have a Displayport connector ?

He's got a Hazro 30" that just has DVI-D iirc

Mini DP to Dual link dvi would be the best bet if it cannot be fixed under warranty or by himself.

I have an apple dp to dvi active adapter and also a bizlink one so im covered.

Would prefer to use dvi or hdmi though lol

Yeah didn't put it very well but going from a HDMI 1.4 output at the GPU stage to actually getting the data at 1440/1600 displayed on the screen even using HDMI 1.4 supported hardware at each end or going through dual link DVI at some stage isn't the best supported standard and can be a bit hit and miss.

Most commonly, displays only support HDMI 1.2. It's very rare to find a display that will do the fully-compliant HDMI 1.4a signals necessary to do >1080p via HDMI.

 

[Diagro]

What i was trying to find was an adapter that took a FastHDMI signal and turned it into dvi Dual link for a DVI-D ONLY monitor :/

 

[Thracks]

I've never seen such an adapter. Fast HDMI is so new and rare I can't imagine there's much of an ROI to make such an adapter for any manufacturer.

Why not just use the bizlink adapter you said you've got?

I'm currently using 2 of them for my 2560x1440 monitors, and the third is just on the DVI-D output.
