first of all, nothing is wrong with my system, Im just trying to understand more about this technology Im using Macmini HDMI to a HDMI monitor, wich is 1080P compatible. I set the display to 1600x900, but the monitor clearly shows as getting a 1920x1080 resolutuion image. But Im getting the "viewing experience" of 1600x900. sometimes I set the resolutuion to 1080P in order to watch a 1080P video, and everything works correctly too. Now, Its my believe that maybe the HDMI cable only supports 720p or 1080p. In adition, the monitor may also only acept 1080p. So, defenetly there is some type of conversion somewhere in order for me to get a 1080P image with the feel of 1600x900. Is this conversion done in the Macmini or is it done by the monitor?
