TV Out
TV Out
Sends the device's screen buffer as a live 1280x720 DVI video signal. Hardware validation is still in progress, so save important work before starting video.
The screen
An empty log box fills most of the screen. Two lines are printed into it as soon as the screen opens, saying Green sends 1280x720 to HDMI and that the LCD freezes while it streams.

HOME leaves the screen from here, as it does everywhere else in the menu, and stops the video on the way out.
Starting and stopping video
Green begins streaming the current screen image out continuously as DVI video, over GPIO12-19 on the DISPLAY processor. While it runs, the LCD stops updating and the log prints a reminder that the screen is frozen until Red - that message is stale: Red does nothing here, and HOME is what actually gets you out. Leaving with HOME stops the video and restores the display, so the screen can be reopened and started again afterward.
Serial connections
Starting or stopping video briefly changes the display processor's clock. Active serial connections may momentarily lose data during that transition. If a terminal stops responding, reconnect it after leaving TV Out.
