Although the current HDMI standard (HDMI 1.4) actually supports displays with very high resolutions, you'll face display or graphics card problems. E.g., driver and hardware (single link HDMI) of the integrated Intel HD Graphics 3000 and 4000 restrict the resolution to 1920x1200 at 60 Hz and you'll need a trick to use higher resolutions.
