i am having an issue with my LG OLED77C2 tv that started happening (i believe) once i have updated from web24 to 25. It seems like whenever the tv is displaying a source from any of my four HDMI inputs, while i am watching the screen goes black randomly for a few seconds and it loses audio as well during the black screen. Once this happens the audio usually comes back as soon as the image does, however not always. The audio might dissapear completely. In order to fix that i might need to power cycle the tv or unplug the hdmi input out, wait a little and then plug back in. Moreover, sometimes when the black screen flash happens it cripples most of my native apps on the tv. So if i switch to netflix or youtube right after the black screen flash, both apps populate normally all the video/film options in the main menu but when i try to actually play any of the video/films, they dont play and it is throwing an error. These black flashes never happen when i am watching netflix or youtube. Only when using my hdmi inputs. ive changed brand new high quality cables but that did not fix my issue. For the xbox i was already suing an ultra hish speed 2.1 hdmi cable but ive re placed that as well with a brand new one. ive also changed the tvs main board to a brand new and it still happening. Once the dealer changed the board, the tv was behaving normally without the issue. However after a few days i updated the tv to the latest firmware and this started happening. what do i do?
FYI: I tried EVERY SINGLE option to troubleshoot the issue. Disabled VRR, AMD Freesync, ALLM, HDMI Deep Colour, SIMPLINK, I basically set my tv to display video and audio in the most archaic way just to troubleshoot. Still doing it. I am using an xbox series x on input 1 and a mag520 box on input 3. Does it on both sources. Moreover, in case this helps whenever this happens while on the xbox the Dolby vision/HDR logo appears on the top right right after the video comes back once the black screen is over depending on what settings i have the xbox on. Also swapped to different inputs. Still doing it

I recently updated the firmware on my LG43UH610V. Now I constantly get "Wired Lan cable disconnected" / "Wired network is connected" messages even while watching a video file from my NAS. The TV is connected and using the network while getting these messages. It has always been on a fixed IP address on the LAN.

I used to extend my screen from PC/Notebook to my TV but i stayed a long period without do it.
It happens that since a few days ago i am needing it and for my surprise is not working anymore. Tried other cables, updated the drivers and O.S. but nothing worked. So i decided test at the room's TV (LG as well) and worked perfetcly.
I looked for all internet and youtube for similar issues and a solution but couldn't find it, until i receive my weekly mail from this forum and remembered it.
I am suspicious that was one of the several updates since i extended for the last time that made this!
So, does anybody could help me, please?
Thanks in advance!

Hello!
I would like to share my screen from my PC(Win10) to my LG TV(OLED55c11LB). Both devices are connected to the same network via Ethernet CABLE. It is not possible to connect with HDMI, devices are in diffrent rooms. When I try to find the TV on the screenshare list it's not showing up although it is visible is my network in explorer. I can easly screenshare from my phone.
I tried the customer support which resulted in nothing except reverting my TV to factory settings. Has anyone done this before? Is it even possible? I would love to be able to game with wireless mouse and keyboard on my TV.

See topic title. I have an Android box connected to HDMI 1 and would like to check if it auto switches frame rate according to the current video file.
Is there any "secret code"?

Question

Hello!
Cable was working fine. Had to unplug TV and cable to reboot because the TV screen kept cutting to black and was up to about 30 seconds each time (it gets progressively longer, until I unplug the TV and cable box, and do the hold-the-on-button-for-10-seconds-and-start-over fix, which has worked in the past for this problem, as well as the app restarting for memory thing). Well, now I’m unable to get the cable signal back.
— I swapped cable box from HDMI 1 to 2 and Apple TV from 2 to 1. No signal from cable in HDMI 2, but Apple TV worked in 1.
— Bought new HDMI cord. No signal.
— Restarted the TV from scratch and re-setup everything No signal.
— Called cable company and had them troubleshoot. No signal.
— Hooked cable box to another TV. Bam! Signal! Works fine!
So, why won’t the TV recognize the cable box? I have Consolidated Communications, but cable’s worked when accidentally set to AT&T, as well as Comcast in the past.
Sorry if I sound dramatic, but I’m really, really irritated that I spent $1900 on a TV that has to be rebooted multiple times a week, and the fact that I’ve seen posts on here regarding the app reset problem dating back to 2017, yet LG’s chosen not to fix this issue. It’s ridiculous.
