Can HDMI output 2560x1600?
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?
Solution 1:
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.
Solution 2:
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).
Solution 3:
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.
