I would like to know if I can use 2 displays w/ my 15" macbook pro. Specs: 2.2 Ghz / 2 GB 667 MHz DDR2 SDRAM / Geoforce 8600M GT / NVIDIA 128 MB I currently have a Samsung 24" and would like to get another as I can't afford a bigger one but need the space. Is it possible? Only in clamshell mode? What cable do I need? Thanks these forums are awesome I see simmilar posts but for much different specs.
