HDMI to DVI-D (dual link) or Displayport?

[OrangeLike]

Hi all.

I have an NEC PA301W monitor attached to my workstation via a display port connection.

The PA301W can support acting as a KVM switch and I would like to be able to attach my laptop to it when needed.

It can take input from either Displayport or DVI-D (dual link)

However my laptop only has D-Sub and HDMI outputs.

Are either of these convertible to either of the inputs the monitor accepts? If so, what would I need to do it?

Thanks in advance all!

HDMI to DVI-D (Dual Link) Adapters... only sound will not pass through.

Do these even exist? A single link HDMI signal is not electrically the same as a dual link DVI signal.

They do, thus my confusion

A true HDMI to DL-DVI adapter? Or just one that has pinouts for a DL-DVI cable? /hmm

I'm not sure. If it just has pinouts, would it work (at a lower resolution) or would the monitor not know how to handle the signal at all?

Considering it's a PA301W, it will probably work, just at a lower resolution.

It may even have the electronics to extract full resolution from a passive HDMI -> DL-DVI conversion, even though that would be out of spec for DVI. Pure speculation at that point though.

So worst case doesn't involve messing anything up?

It's not going to be possible to run at 2560x1600 with a passive converter, but this will work for lower resolutions. HDMI is the functional equivalent to SL-DVI, which means you're limited to 1920x1200 and lower. So you'll be able to run your monitor, but not at its native resolution. And it's perfectly safe BTW, so it won't mess anything up.

The only way this could work at 2560x1600 is with a new type of active adapter, which unfortunately doesn't exist. You'd need something that accepted high bandwidth HDMI 1.4a (i.e. FastHDMI) and then converted it to DL-DVI. However it's very likely your laptop doesn't evens support FastHDMI, so even this would probably be a dead end.

Thanks for the explanations and the reassurance that I won't damage anything. The restricted resolution is fine - hooking up the laptop is more about convenience - my workstation is for the actual work!

There is a dual link HDMI spec, and as far as single link, the spec and available bandwidth allows for greater than 1080p on 1.3 and 1.4, but those signals wouldn't work converted to DVI.
