Yes, it works on a normal display. I tried the cheap one hdmi splitter box from China but still doesn’t work.
So I found the solution to hookup to dvdo.(2x-> hdmi2vga with power -> d-sub2comp-> dvdo (work!) the picture crisp and clear but sometimes the signal unstable. the picture disappear on the screen.
I think you are right. they need more signal strength for the dvdo. what do you think in the link down below?
