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

Hi everyone,
I’m running into a very inconsistent issue when streaming my Windows 11 PC with apollo (fork of Sunshine) to my LG C4 TV using Moonlight (webOS).
The setup worked perfectly for about 6 months at 2K / 90 FPS with high bitrate.
Around 2–3 weeks ago, the issue started without any clear change on the PC side (possibly after a webOS update).
Symptoms:
• Moonlight on the TV shows “connection unstable” with a black screen
• Behavior is inconsistent and unpredictable :
Sometimes nothing works at all with black screen Sometimes 2K / high bitrate work or not yesterday 2K didn't work but lowest resolution (1280x..) worked • Streaming to my phone works fine, so the host PC and network seem OK
What I’ve tried:
• Clean reinstall of Moonlight on the TV and Apollo/Sunshine on the PC
• H.264 only (no HEVC, no AV1, HDR off for testing)
• All bitrate / FPS / resolution combinations
• Ethernet and Wi-Fi
• Different Windows display modes
• Virtual display disabled
Setup:
• Host PC: Windows 11, NVIDIA GPU (RTX 3070)
• Apollo installed on PC
• LG C4 TV, webOS 10.2.2, sideloaded Moonlight client (1.6.36)
• PC and TV tested on both Ethernet and Wi-Fi (2 gbps internet speed on my computer)
• Streaming to other clients (android phone) seems to work reliably
Feel free to ask me any information needed
Thanks for your help

LG OLED65C2AUA.
webOS TV version webOS25/10.2.2-61. up to date.
software version 33/22.95 up to date.
whenever I watch Netflix it freezes indiscriminately. Once it happened at minute 1:29 of a movie although it can happen at any time. the Netflix error message says to restart which I do but the issue persists. it is to the point where it is unwatchable. however, when I watch it through Firestick it is fine. Other TV's do not have the issue so I am thinking it is something with the TV. I have uninstalled and reinstalled the app on the TV. I have powered down the TV. I have reset the router. I am wired with ethernet so not using wifi. any help would be appreciated to fix this issue.

I just purchased the LG UHD 43UP76 advertised as real 4k however the YouTube App is running at 1080p. Which means 4k content is downsampled to 1080p then reupsampled to fit the 4k pixel grid and the image quality is awful.
i assume WebOS runs at 1080p and simply upscales to 4k on low end 4k TVs, this same with high end TVs??

Hi, Netflix is working fine EXCEPT for a little black square running on top, nonstop, while watching.
I've reinstalled Netflix, reset my LGTV, disconnected/connected everything. Can't figure out what's wrong.
Thanks.
