There are different versions of HDMI with different maximum throughput. If it only makes 1920, you have a problem.

The DVI converter might work if it is active, i.e. has its own power supply. For the DP->DVI adapters this is a known problem. There is not enough power in the DP input to drive the 2560er DVI signal. I figure its the same for HDMI->DVI.
