I've got a mini hooked up to our TV via HDMI but I almost always use it via screen sharing with the TV either off or switched to a different HDMI input. In this scenario I think that the GPU in the mini is inactive and that the CPU handles everything.
If I get one of those headless display port adapters that fool the mini into using its GPU will that effect my ability to use the HDMI on those instances when I do actually want to use the TV?
