I have a mid 2009 unibody MacBook Pro 17". It has a NVIDIA GeForce 9400M and a NVIDIA GeForce 9600M GT graphics card. According to Apple, I am able to output a max resolution of 2560 x 1600. I plan on using a Mini DisplayPort to DisplayPort cord to connect my MBP to the 4K Samsung Monitor. My question is, will I be able to use the 4K monitor at the 2560 x 1600 resolution with my old MBP? Or, are my graphics cards not compatible with the monitor at all since they can't output 4K? I am waiting for the Broadwell MacBook Pro refresh before upgrading my current MBP. With this being the case, I'm wondering whether I would be able to use the Samsung 4K monitor with my current MBP? Once the new MBPs are released I would get one and would continue to use the 4K monitor, but with it instead. This way I avoid buying a monitor specifically for my current MBP and then a 4K monitor once the new MBPs are released.
