2560x1600 is the output resoultion for dual-link dvi. HDMI can convert to dvi. But can HDMI convert to dual-link dvi?

I understand there are different versions of HDMI. I want to hook up a Samsung 305T 2560x1600 monitor to a laptop with an HDMI out port. Is this possible, and if so what are the conditions which make it possible?

  • How did this work out for you? Were you able to display 2560x1600 on your DVI monitor? I'm in the same situation and am about to give up. :-)

An HDMI revision 1.4 cable can support that resolution up to 36-bit/px (Deep Color). Provided your hardware complies with 1.4 (or 1.3 at 30bit/px), then you should be able to run that resolution. If your hardware was produced within the last few years, that shouldn't be a problem.

No. The Samsung 305T only has a dual-link DVI port.

The output must be electrically compatible with dual-link DVI to support a resolution beyond 1920x1200: A Dual-link DVI-D connector or a 29-pin Type B HDMI connector (which has not been used in any products yet).

  • Common cables exist for transposing HDMI to single link DVI and vice versa. Does no such cable for HDMI 1.4 to dual link DVI? Is such a cable impossible, impractical, or is such a cable not yet on the market? Nov 5, 2011 at 14:51
  • HDMI 1.4 uses higher clocks, while Dual link DVI uses more lanes. So a simple passive adapter cable is not possible, it would require active conversions.

There are so-called ACTIVE adaptors which can convert HDMI to dual-link DVI. They cost around 100 dollars or so. The real question, however, is whether your notebook can output a resolution above 1080p via HDMI - most can't. The Geforce 330m and 540m for example don't support it.

  • The notebook is not yet purchased - still in planning phase. Assuming the notebook's video can output 2560x1600, I would just need to purchase an active adapter? Does "active" mean the adapter must do processing, and does this slow the transfer rate appreciably? Nov 5, 2011 at 17:15
  • @JM. if you haven't purchased the notebook yet, why not just look for one that supports DisplayPort? You can get a DisplayPort to Dual-Link DVI adapter for about $25, and won't be limited by HDMI's problems with going above 1920x1200.

  • Where did you see such an adapter?
