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

Ballpark Transformed With 11 Digital Signage Displays Including
Main Videoboard and Ribbon Boards Spanning 842 Square Meters
SEOUL, April 8, 2025 — LG Electronics (LG) is strengthening its leadership in the global commercial display market by providing state-of-the-art display solutions to Fenway Park, the home of the Boston Red Sox and the oldest ballpark in Major League Baseball (MLB).
In late March, LG installed a massive main LED videoboard in centerfield at Fenway Park, measuring 30.5 meters wide by 11.5 meters high and covering an area of 350.75 square meters. Additionally, LG delivered a comprehensive display solution comprising 11 digital signage installations. These screens span a combined area of approximately 842 square meters, including a notable 171 square-meter ribbon board display measuring 21.6 meters wide by 7.9 meters high.
Featuring sophisticated High Dynamic Range technology, LG’s commercial displays strike a meticulous balance between dark and bright elements to deliver exceptionally clear and lifelike imagery. They offer high luminance exceeding 7,000 nits, IP65-rated water and dust resistance, as well as flexible configurations – all tailored to the outdoor conditions of stadium environments.
Starting April 4 (local time), fans had the opportunity to experience the action of the game in vivid detail, delivered by LG’s LED signage displays during the home opener – the first Fenway Park matchup of the 2025 MLB season between the Boston Red Sox and the St. Louis Cardinals.
LG’s innovative display solutions are set to lead the transformation of the beloved Massachusetts ballpark, the iconic stadium that has shared in the joys and sorrows of American baseball fans for more than a century since its opening in 1912.
With a focus on redefining the fan experience, LG has established a strategic partnership with ANC, the agency managing stadium operations and advertising on behalf of Fenway Sports Group, the owner of the Boston Red Sox. Together, they aim to deliver immersive entertainment to sports fans across various regions in the United States, including Boston.
“This collaboration will elevate the in-venue experience for our fans with cutting-edge technology while also expanding LG’s presence through dynamic activations that will engage Red Sox Nation all season long,” said Troup Parkinson, Chief Marketing & Partnerships Officer for the Boston Red Sox.
Meanwhile, LG is accelerating its media entertainment platform-based service business, targeting global sports fans by integrating the display businesses – which include TVs, monitors and signage – under its Media Entertainment Solution (MS) Company.
Earlier this year, LG partnered with AMB Sports and Entertainment to provide displays spanning 141 square meters inside the perimeter of the Mercedes-Benz Stadium in Atlanta, Georgia. LG’s commercial display innovations, including LG MAGNIT and indoor/outdoor LED signage, can also be found at Atomic Golf, a massive entertainment complex in Las Vegas.
“We are thrilled to be able to strengthen our partnerships with prestigious global sports franchises,” said Park Hyoung-sei, president of the LG MS Company. “We will continue to enhance the value of customer spaces and strive to provide differentiated media entertainment experiences.”

Question

Hi all, I have this 4K LG 49UF772V TV which has had this issue since I bought it second hand and I'm wondering if anyone has any idea how it can be fixed as I am looking to sell it.
The issue: On the LG menu and main home screen + sub menus and programs such as Netflix, there are black squares all over the display which makes it impossible to use. However, the TV works flawlessly when using the display with a HDMI device connected.
I suspect this could be either a software issue since there's no physical defects with the display itself. The TV has the latest software update running (04.06.25). I've attempted to reflash it and downgrade it but I haven't managed to find a way to do it.
Also note that only 1 of the 3 HDMI ports work. The other two gives no output when a device is connected.
I have also carried out a factory reset and this has not made a difference.
I have attached a short video showing the TV connected to chromecast and the display working as expected and then pressing the settings button yields artifacts/small black squares. + some pictures showing this.
Thank you in advance!
