The sound and picture are out of sync when screen mirroring from my iPhone 16 Pro to my LGQNED70A6A TV, using the internal speaker. I have tried all the recommended tips in the settings to cure the issue with no success. However, when I isolate the TV from the mains supply for 60 seconds and restart it, the syncing issue is cured but degrades after a day or so. My iPhone software is up to date and there is no firmware upgrade available for the TV. My LinkSys router has a full fibre connection. The only connection into the TV is the mains supply. Any help much appreciated. Thanks in advance.

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

With Uncompromised, Low-Lag Performance at 4K 144Hz, LG’s Advanced Wireless
Technology Sets a New Standard for Clutter-Free Gaming and Home Cinema
SEOUL, July 3, 2025 — LG Electronics (LG) has announced the global rollout of its newest wireless OLED TV series, the LG OLED evo M5 – a TV that combines LG’s advanced True Wireless technology1 with the industry-leading OLED picture quality of the G52 to reimagine the TV experience in a clutter-free setup.
The M5 sets a new gold standard for premium wireless home entertainment. LG’s True Wireless technology eliminates the cable connection between the TV and external devices, thanks to LG’s proprietary Zero Connect Box,3 a visually lossless wireless video and audio transmission solution. Delivering ultra-smooth content with low input lag up to 4K 144Hz,4 the M5 boasts performance on par with a wired connection.
The M5 offers next-level wireless technology for competitive gamers demanding ultra-responsive performance. Building on the legacy of LG’s OLED evo series, the M series is the only wireless TV compatible with both NVIDIA G-SYNC® and AMD FreeSync Premium to deliver a tear-free, stutter-free gaming experience even during fast-paced action up to 4K 144Hz. Certified by Intertek for Qualified Gaming Performance, the M5 features an ultra-fast response time of less than 0.1ms,5 delivering smooth, vibrant visuals in razor-sharp clarity.
The M5 is the optimal TV for those seeking both a superb gaming experience and a more flexible, cleaner setup. A conventional TV offers multiple ports for commonly used HDMI devices like gaming consoles on the back of the screen, causing viewers to walk to the TV to power on devices or switch inputs. But on the M5, these ports can be found on the Zero Connect Box, enabling consoles to be placed within reach – on a nearby shelf, inside a cabinet, or next to the sofa. As a result, there are no cables between the TV and entertainment devices.
The M5 is also a top-tier choice for home cinema enthusiasts, featuring Dolby Vision, Dolby Atmos and Filmmaker® Mode with Ambient Light Compensation for cinematic accuracy. Powered by the α (Alpha) 11 AI Processor Gen2, it offers enhanced depth and detail with AI Picture Pro, while AI Sound Pro enables immersive 11.1.2-channel audio. LG’s upgraded Brightness Booster Ultimate technology boosts screen brightness by up to three times compared to conventional OLED models.6 The M5 has also received UL Solutions’ “Perfect Black” and “Perfect Color” verification, along with certifications from Intertek for 100 percent color fidelity and 100 percent color volume. A “Perfect” grade by TÜV Rheinland7 further affirms the M5’s capability to maintain clarity even in bright indoor conditions.
With a flush-fit design and no visible cable clutter, the LG OLED evo M5 delivers a truly immersive entertainment experience with the uncompromised performance of a wired setup.
“For 12 consecutive years, LG has led the global OLED TV market and we are opening a new era of television with our leadership in wireless TV,” said Park Hyoung-sei, president of the LG Media Entertainment Solution Company. “The OLED evo M5 exemplifies our commitment to innovation and our pursuit of the ultimate in premium home entertainment.”
The LG OLED evo M5 series will roll out globally in 97, 83, 77 and 65-inch screen sizes. To discover more about LG’s wireless OLED TVs, visit

4 LG 2025 OLED M5 series TVs up to 83 inches (screen size) provide support for 4K@144Hz. The 97-inch OLED M5 supports 4K@120Hz.
5 LG OLED displays been certified as “0.1 response times (Gray to Gray)” and “Qualified Gaming Performance” by Intertek.
6 Applies to 65/77/83-inch M5 models, compared to the same sizes of conventional OLED models (B5 series) in a 10 percent window.
