LGTVCompanion VS samsung-tv-control

Planning on picking up this exact model soon, just wanted to share this to wake the tv on lan when waking pc from sleep: https://github.com/JPersson77/LGTVCompanion

I am attempting to set up the LG TVCompanion app (github here) after entering the MAC/IP/Device Id etc. I attempt to hit the "Apply" button and am getting this error linked here. I have no idea what to do..?

u/Xurxor https://github.com/JPersson77/LGTVCompanion/releases/tag/v3.1.5 testing the app to auto shutoff and starts the screen over the network (my tv is via WIFI)

Get the LG TV Companion app to save yourself a lot of pain.

One of the really nice things about the C2 is way, way more people own one, and that means the community is big enough that it has solved its own issues. Literally every issue you can think of has a solution. For example they've built an app (https://github.com/JPersson77/LGTVCompanion) that handles turning it on and off for you to match your PC's state. And even better, as someone who frequently streams games from my PC to my Nvidia shield in the living room, the app has a check box that allows it to shut my PC screen off while still telling the computer that an HDR connected device is attached which allows me to avoid unnecessary runtime (and eventual burn-in) on the pc monitor when i'm not actually looking at it while streaming. The only way to do that with an the ASUS monitor is to buy a dongle that tricks your PC into thinking it's another display and switch to that when you're streaming which would be totally janky.

There is software for LG TVs that does that pretty well: https://github.com/JPersson77/LGTVCompanion

Check out LGTVCompanion on GitHub! You can mimic auto wake from sleep so you don’t need to use the remote to turn the tv on.

The probably best, but I'm not sure if reliable solution would be something just like LGTVCompanion. I found the samsungctl and samsung-tv-control apps, they might do the trick (if they're compatible with QN90B), especially when configured with task scheduler on events, but I count not get them to work yet. I'm not that into the programming stuff and that could just be my fault (so that maybe someone will be able to give me some tips how to use it?).
