Monitor out not working?

You probably need to upgrade your firmware. The version that mine shipped with from Sweetwater (1.03 or so?) the monitor out did not work. This is fixed in 1.04, but after you update the firmware you have to boot up holding down the system key the entire boot. This clears out the system cache.
1.05 is out and I upgraded again to that, but there are some issues with audible pops and cracks, so you might want to get to 1.04 and stay for a bit. Backup your device before making any changes!
