You want to make sure you're in extended desktop mode, and your computer is set as the main screen, with your projector as the secondary. For more info, try posting on the official NuVJ forum: http://www.arkaos.net/forum/viewforum.php?f=24
hey @ashapsyki, thanks for trying it out. I did a little research, and it seems like there is no solution for pushing the on-screen image to the HDMI out on the Droid X at the moment - Motorola has limited this output to the Gallery application. There was a solution called Real HDMI Out but it has been pulled due to a problem Motorola introduced into their 2.2 kernel. I do hope they fix it!
