Hello, I know that the resolutions available for external monitors is depending on the specifications of the GPU. However, somewhere on the net I read that using mini display port to hdmi cable could lead to less available resolutions to choose from. Is this correct? Currently I am connecting mini display port to hdmi of a LG 38" monitor. It is supposed to output 2560x1600 according to the specs of my MBP 2010 17". However, the best it can do is 1080p. Before I purchased the monitor, LG recommended using mini display port to display port cable rather than via hdmi.
