Simple Script for Turning the Screen Off and On

[omoknen]

I am really happy about this program it is really getting my some relief of turning it on, but I could use some help.

I am looking for bat script which could turn off the screen off and on. I could use some pointers as I do not do this that often. (novice) I did see the example scripts but they seemed complicated for what I want to do.

I had to work on this computer remotely thru vnc because I was in a different location, and the tv was powered off. This caused the earc to switch from the soundbar to the tv speakers.

I figure if I could turn off the screen maybe that wouldn't happen.

Thanks

Hi @omoknen you can control a lot of things via command line . Specifically you want to look at sending -poweroff and -poweron, i.e. in a .BAT file you would use:
"C:\Program Files\LGTV Companion\LGTV Companion.exe" -poweroff

There are also commands for selecting TV's sound output if you want to look at that (-soundoutput)

I think I got it, but I have a problem. There is actually another tv in the house, but it isn't connected to a pc. I used the LGTV Companion to not automatically manage it, but I think it thinks it is device 2.

C:\Essentials\LGCompanion\LGTVcli.exe -screenoff Device1 "LG1" -soundoutput external_arc
{"Device1":{"payload":{"returnValue":true,"state":"Screen Off"}}}
{"Device1":{"info":"Cannot relay luna response."},"Device2":{"error":"No pairing key. Check the device configuration in LGTV Companion UI"}}

Is there a way to get it to ignore the other family member's tv.

You can send the command to whichever device you like by adding the name or device id after the command. I see that you do this for the first of the two compounded commands. I suspect in your config Device1's friendly name is "LG1" so you only need to use one of them. Then add the device identifier also to the second command. Like so:

LGTVcli.exe -screenoff Device1 -soundoutput external_arc device1

Edit: another variant if you don't want the app to control the other TV, at all, is to remove it from the main UI. Remember to press "apply"

Okay I fixed the other tv and removed it, but somehow I managed to create a zero file for for the cli version.
Doing this command.

LGTVcli.exe -screenoff Device1 -soundoutput external_arc device1

It gave me an access denied message and I checked it and lgtvcli.exe is a 0 file size modified when I ran the command, maybe I had a another "-" somewhere. I don't know.

Took me awhile to figure it out.

I tried to run the installer again, but there is no repair. If I remove it application and reinstalled it will my settings still be saved?

[JPersson77]

Maybe check if your antivirus did something funky? I don't see how the executable could be essentially deleted. If you uninstall and then reinstall the settings are saved.

[omoknen]

I checked my quarantine and antivirus no messages. At least this old woman finally remembered I backed up the drive last night.
I was able to recover the file and run the commands without somehow writing a zero file.

lgtvcli.exe -screenon device1 -soundoutput external_arc device1
{"Device1":{"payload":{"returnValue":true,"state":"Active"}}}
{"Device1":{"info":"Cannot relay luna response."}}

lgtvcli.exe -screenoff device1 -soundoutput external_arc device1
{"Device1":{"payload":{"returnValue":true,"state":"Screen Off"}}}
{"Device1":{"info":"Cannot relay luna response."}}

Just have to figure out how to put them in a script.

Nice! Well, you can do it in many different ways but perhaps the most simple way is just two separate and aptly named scripts,, which you double click as appropriate. Additionally you coould put two regular shortcuts on the desktop, with keyboard shortcuts. This way you could trigger them with keyboard shortcuts. Please let me know if I can help
