Disable LCD when plugged in through HDMI

[orrtanna]

No.  There is not.  Are you worried about battery life?  You can plug power into the MicroUSB to keep the battery charged while playing via HDMI.

Figured as much, glad to have a definite answer though. Yeah I was worried about battery life and general wear on the screen. Seemed more aestetically pleasing too having the screen off, but it isn't a huge deal. Thanks!
