I know there are small USB boxes which are able to pass through image from HDMI (and record it) to computer. Is there something similar which would enable me to see stuff from HDMI on my Mac?
Why: I am trying to discover possibilities how to use iMac, which I might be buying, as a target screen. I read there was this possibility for older iMacs, but only with other Apple computer. I want to connect PS3 or in future maybe some other console/device.
