hi guys, is there a way to check if the dsi touchscreen display (of a remote raspberry) is working or not?

A
tvservice -s command will return this:
Code: Select all
pi@tranquility:~$ tvservice -s
state 0x400000 [LCD], 800x480 @ 60.00Hz, progressive
pi@tranquility:~$

hi, thanks for the reply. I was already aware of the "tvservice -s" command.
But my goal is to monitor the display in real time. Let me explain: If I start the raspberry with the display connected (powered separately from the rasp) and run the command "tvservice -s" the answer is as you say "state 0x400000 [LCD], 800x480 @ 60.00Hz, progressive". But if I disconnect the power of the display alone and relaunch the control command I get the same answer.
Is there an alternative command to identify correct operation in real time without restarting the rasp? Thanks in advance.

There's nothing to monitor. If the display goes off you can't restart it without a reboot.
