HDMI 1.4 and dual link DVI conversion /adaption
- Thread starter chasanova

Display port is different to HDMI and DVI-D. Any conversion to or from display port will need to be an active adapter.
Between HDMI and DVI-D, it depends on the resolution and refresh rate.
The standard for 1920x1080 @ 60 Hz works with both, so you can easily convert from DVI-D to HDMI or HDMI to DVI-D with just a cable or passive adapter.
DVI doesn't typically support audio or HDCP, so you lose these features.
HDMI 1.4 supports resolutions above 1920x1080, but no refresh rates above 60 Hz.
Dual link DVI-D supports resolutions above 1920x1080 and refresh rates above 60 Hz.
HDMI to dual link DVI-D adapters typically just have a dual link connector, but you still limited to 1920x1080 @ 60 Hz as far as I know.
What outputs are available on your graphics device?
What inputs are available on your display device (monitor or TV)?
What is the resolution and refresh rate supported by your display device (monitor or TV)?

output device is lenovo yoga 2 pro putting out 1.4 hdmi (type d micro hdmi connector) at or above 2560 x 1600
monitor is Dell 3007 WFP with only Dual DVI-d inputs. so I 'm thinking there is signal compatibility in terms of rates and resolution, and wondering if there is a cable /adapter that gets me there?
Thanks with apologies for my ingnorance.

This isn't a stupid question at all.
HDMI 1.3 supports 2560x1600 @ 60 Hz and this support is carried forward to later versions.
Dual link DVI-D also supports 2560x1600 @ 60 Hz
To do this though DVI transmits two different channels (hence dual link).
Have a look at a connector like this:

This has a DVI connector with the dual link pins included, but in the specification they state "provides up to 5 Gbps of bandwidth". This means it is limited to 1920x1200 @ 60 Hz, a single link DVI-D.
The only active adapter I found to output dual link DVI was from display port, not HDMI:

In your original post you said you had something like this already.
Unfortunately, the conclusion I've come to is that you are going to be limited to 1920x1200 @ 60 Hz.
You should be able to achieve this with any HDMI to DVI adapter or cable.
If your tablet supported Displayport or Dual link DVI-D, you would be able to support the full resolution.
If your monitor supported HDMI 1.4 or higher, you would be able to support the full resolution.
From what I can see though, the adapter you need to display this resolution just doesn't exist.
Note that even if you buy a monitor with HDMI input, chances are this only supports HDMI v1.2.
An example is the Dell U2713HM. This monitor supports display port (2560x1440), Dual link DVI-D (2560x1440), HDMI (1920x1080) and VGA (2048x1152). That information isn't listed in the monitor specifications.

I had another idea for your problem.
You can buy external graphics adapters that connect via USB.
If you can find one that supports dual link DVI @ 2560x1600 resolution and you can install the drivers on your tablet, it might work.
The closest I found from a google search was an external displayport adapter that supports this resolution:

I'm on the verge of trying this solution myself, after having exhausted many other options.
Fingers crossed! I will post here once I try it.

Sorry to hear that. I want to share what I have gone thru before deciding to purchase this adapter: http://www.startech.com/AV/Displayport-Converters/Active-DisplayPort-Dual-Link-DVI-Video-Adapter-Converter~DP2DVID2
1. I have a 3007WFP monitor that only has Dual-Link DVI input. I can only get 1280x800.
2. I have an HP Compaq Pro 6300 Business PC that has Intel HD Graphics with a DisplayPort ++ output (according to the manual it supports 2560x1600 @ 60Hz ONLY by using Dual-Link DVI cable and HP DisplayPort To Dual Link DVI-D Adapter NR078AA)
3. I have an AMD Radeon HD 6350 Video Card that is supported in the PC manual...Although it does NOTsupport Dual-Link DVI capable monitors according to the manual)
4. I have purchased a DMS-59 to dual DVI-D adapter for the AMD 6350. (DVI has all pins but does not support Dual-Link DVI, probably because of the video card). Results: 1280x800
5. I have purchased two different Dual-Link DVI Cables. Results: 1280x800
6. The only cards that are supported on the PC manual, cost more than the HP adapter.
7. I have purchased an NVIDIA 210 Video card that supports 2560x1600 and has a DVI-D Dual-Link output. (it is not listed in the PC manual as graphic solution) Results: 1280x800
I am going to purchase the HP adapter or Startech and let you know the results.
