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?

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.

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? –  steampowered Nov 5 '11 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. –  nhinkle Nov 7 '11 at 18:51
    
Where did you see such an adapter? –  chx Jun 20 '12 at 22:59

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? –  steampowered Nov 5 '11 at 14:51
