the picture degraded. In fact not so much the picture in general but processing of text, logos, subtitles etc. Like some bad and heavy picture compression is going on. I did reset the TV and cold reboot and tried with all possbile picture combinations but nothing helped. Now Im stuck until the next official update because it seams that LG uploaded the TEST/BETA firmware! This info I found out .

      Factory Reset, Remote Won't Work, Stuck on Press the OK button(wheel) on your remote (55NANO81ANA)
      By David Daul
      My magic remote and my Roku remote stopped working for turning off power so I performed a factory reset after troubleshooting to get the remote working.  I am now stuck at the 1st screen of the Factory Reset which says "Press the OK Button(wheel) on your remote."  Well... this really stinks because the remote doesn't work!!!  I have tried a USB mouse, a new magic remote, other LG Remotes with no luck.  I have also tried using the button on the bottom of the tv.  And, I contacted support which was just an exercise in redoing everything I had already tried... No Luck!!
      This is a Nano Cell 55NANO81ANA which is basically just a big brick now since I cannot even use any of the inputs.  Does anyone have a trick for getting past this initial screen???
      Thanks for the help.

      LG Teams Up With Razer and MediaTek to Present First-Ever Bluetooth Ultra-Low Latency Technology
      By News Reporter
      Companies Set to Introduce Cutting-Edge Bluetooth Ultra-Low Latency Technology
      that Revolutionizes Cloud Gaming Experiences for webOS Smart TV Users

      SEOUL, Sep. 27, 2024 — LG Electronics (LG) has collaborated with Razer and MediaTek to introduce the world’s first Bluetooth Ultra-Low Latency (BT ULL) Controller at LG webOS Summit 2024 on September 27. This groundbreaking technology was showcased through an LG webOS smart TV and Razer’s Bluetooth gaming controller, demonstrating the game-changing 1ms input lag.
      The webOS summit, which welcomed 300 representatives from 140 partner companies – including content developers, producers and providers – from 24 countries, shared LG’s strategic vision and future initiatives for expanding its AI webOS ecosystem and platform business.
      Razer, a leading global lifestyle brand for gamers, has developed the first game controller featuring BT ULL technology. To showcase its upgraded performance, LG and Razer compared a BT ULL-enabled Bluetooth game controller to a standard controller during the event. The demonstration highlighted the superior responsiveness, reduced input lag and control precision of the BT ULL technology across various cloud-based games, including FPS, fighting and racing titles.
      The latest BT ULL technology offers the perfect cloud gaming performance, catering to competitive players who require lightning-fast response times to excel in their games.
      In an industry first, LG plans to introduce a certification program for third-party game controllers in the near future to ensure BT ULL-supported controllers work seamlessly with LG webOS smart TVs. Razer will be the first company to obtain LG’s certification.
      Meanwhile, LG and MediaTek, a global fabless semiconductor company, are jointly developing the BT ULL technology to be integrated into MediaTek’s Wi-Fi “MT7921” chipset. This chipset will also feature the efficient and reliable Wi-Fi 6 technology from MediaTek’s Filogic series.
      These collaborative efforts aim to enable LG webOS smart TVs owners to immediately dive into online multiplayer cloud games with the enhanced response times, delivering unprecedented levels of realism during gameplay.
      The latest premium LG OLED TVs and LG QNED TVs, supporting refresh rates of 120Hz or higher, are scheduled to launch in 2025 with BT ULL technology.
      “LG is committed to consistently introducing more advanced features designed to immerse gamers in their favorite titles and to differentiate its gaming experiences,” said Baik Seon-pill, head of the LG Home Entertainment Company’s Product Planning Division. “As the LG webOS platform evolves, so will the features that make it the ultimate gaming platform for every type of gamer.”

      LG 49UB850V LED TV Easy Way to Update or Install Network Browser
      By forum1
      My LG 49UB850V LED TV  browser is too old. The most of the pages not work any more. How to easy update just one simple browser app? For example, often browser show error during open new page. It show certificate expire problem and page not load at all.
      This mean LG sell product without update at least browser certificate and now we are stuck and can not even load one page from WWW. 
       
      Shame on you LG. I will not buy any more from you.  How dificolt is to release new update to update OS certificates? Microsoft Windows did this, android did also for old phones, etc... Really, can not undestend this asian people from Korea.

      Default audio selection is never remember on TV start
      By starwoodtech
      I have a 65 Inch LG OLED evo AI C4 4K Smart TV 2024 - Model OLED65C4PUA.ACC. here have been a many weird things happening. This is one of them:
      Whenever I turn on my TV, it doesn't remember the audio settings I chose before. I repeatedly need to set my audio for the input I am using. I ofter select APPLY TO ALL INPUTS to try and make sure it's the same regardless of which input I use, but it still reverts all changes.
      Does anyone know what this happens?
