Is there any possible way to turn the screen off on the Touch Pro while running video out? I have a Pico Projector that we all watch football games but the battery is dimminished in no time using data package and screen on. Was wondering if there was any way to turn it off because if its hooked to the video out cable and you hit the power button it just turns right back on. Thanks so much in advance.
