I used now HDMI to HDMI to boot without cache, from past experience it should blink (unless 'without cache' will make a difference. Ill put that to the test). it definitely blinked during POST, just like Dell's mDP to DP.
Here's a comparison between the blinks at POST, and the DVI to HDMI which has none:
That is normal behaviour. Does it blink when OS X is booted up?
