Just got a new 55in C4 and a Denon DHT-S316 Soundbar. With my very old LG I like to have the TV connected to the speakers during the day and in the evenings I would switch to bluetooth headphones. I could easily turn off my headphones and switch back to the optical sound output with no issues.
However I tried this and while I connected my headphones with no issues, once I disconnected I couldn't get the sound to come back through the sound bar without having to with the TV and sound bar off which feels crazy at this point in time and the cost of the TV when my very old LG did this with now issues.
Any suggestions much welcomed.

Designed for the Healthcare Sector, Company’s Latest Medical Monitor
Provides Impressive Imaging and Convenient Features
SEOUL, Oct. 9, 2024 — LG Electronics (LG) is launching its new 31.5-inch surgical monitor (model 32HR734S) featuring advanced Mini LED display technology. Designed to provide color video displays of images from surgical endoscopes, laparoscopic camera systems and other compatible medical imaging systems, LG’s monitor has received 510(k) clearance from the U.S. FDA, indicating it can now be sold in the U.S. The 32HR734S’s Mini LED technology enables precise brightness control and provides a wide color range, optimizing image clarity and color, making it an ideal choice for a variety of surgical applications, including laparoscopy and endoscopy.
The 32HR734S features a 31.5-inch, 4K resolution (3,840 x 2,160) Mini-LED display leveraging thousands of tiny LED diodes as the Back Light Unit (BLU). Delivering 2,000 cd/m² peak brightness and a dynamic contrast ratio of 1,000,000:1, LG’s medical monitor leverages 1,536 local dimming zones to produce clear, detailed images and enhanced visual contrast. The display also provides excellent color consistency across the screen and boasts 98 percent coverage of the DCI-P3 color space.
In addition to its impressive visual performance, the 32HR734S delivers the durability and reliability necessary for surgical settings. Employing Optical Bonding technology, along with Anti-Glare, Anti-Reflection and Anti-Fingerprint coatings on its front, LG’s 32HR734S 4K surgical monitor ensures optimal visibility even in brightly lit operating rooms. What’s more, the front and rear of the product (IP45- and IP32-rated, respectively) offer excellent resistance to water and dust, preventing fluids or particles from disrupting monitor operation during surgeries.
The 32HR734S is also the first LG surgical monitor to incorporate the innovative Clone Screen feature. Clone Screen allows users to duplicate the image being displayed on the 32HR734S on a second monitor (connected via HDMI), significantly enhancing operational efficiency and communication within the surgical environment, especially in situations where multiple medical professionals need to view the same image.
For added versatility, the display’s Mirror Mode makes it possible to flip the on-screen image horizontally, while Rotation Mode can rotate the image 180 degrees to match the orientation of the surgical camera. The 32HR734S also provides Picture-in-Picture (PIP) and Picture-by-Picture (PBP) functionality, the latter allowing the display of up to four different image sources simultaneously. This enables medical staff to view a combination of inputs or images, such as laparoscopic and fluoroscopic images, while monitoring the patient’s vital signs at the same time.
“Featuring advanced Mini LED technology, the 32HR734S delivers the excellent picture quality and convenient functionality needed in surgical settings,” said YS Lee, vice president and head of the IT business unit of LG Business Solutions Company. “We believe our new model will significantly boost efficiency for medical professionals performing and assisting with surgeries.”

As the mobility industry shifts towards software-defined vehicles (SDVs), the importance of automotive displays continues to grow. Advanced display technology is already enhancing in-car infotainment systems and user experiences by presenting drivers with a wealth of vehicle and road-related information, while offering passengers an array of entertaining content.
The trend of incorporating larger and more numerous displays within vehicles, often referred to as ‘screenification,’ is elevating the convenience, safety and enjoyment of vehicle occupants, while also influencing vehicle cabin design. OLED panels, known for their superior image quality and unmatched flexibility (both literally and in terms of design), are increasingly being adopted in the premium auto segment.
Market research firm Omdia projects that by 2030, one out of every two information display units used in premium vehicles will be an OLED panel. Several global automakers are now equipping their high-end models with large, high-resolution displays to meet customers’ evolving expectations and preferences. With their stunning colors, clarity and contrast, OLED panels are raising the bar for automotive displays and are expected to drive the market’s continued expansion.
OLED technology makes it possible to create large, curved and flexible screens for use in digital cockpits. In response to the auto industry’s increasing interest in premium displays, the R&D laboratory at LG’s Vehicle component Solutions (VS) Company has recently developed an algorithm for its in-vehicle OLED displays that compensates for any visual distortion related to viewing angle. This advanced technology, first showcased at Display Week 2024, ensures that LG’s automotive OLED screens deliver consistent brightness and distortion-free colors from practically any angle. As a result, drivers can now see images and text more clearly across all parts of the display, enhancing safety by reducing the time needed to check on-screen information.
LG’s new technology overcomes the viewing-angle limitations typically associated with large, curved OLED displays. Currently, LG is the only automotive display supplier to have developed an algorithm that corrects these particular issues and is now in the process of commercializing this innovation.
Research into flexible OLED automotive displays has been a major focus for LG VS Company’s R&D laboratory over the past year. Kim Kyung-lack, vice president of Display Development at LG VS Company, noted that due to extensive and ongoing efforts, LG is able to offer a wide range of automotive displays leveraging next-generation technology to deliver outstanding performance. Since 2022, LG has been developing advanced in-vehicle displays and now boasts an impressive portfolio of solutions, including screens with rollable, flexible and foldable form factors. The company’s diverse offerings provide automakers with more choices when designing vehicle interiors and offer vehicle users a richer, more varied in-car experience.
Beyond automotive displays and components such as EV motors and smart lamps, LG VS Company offers cutting-edge in-vehicle software platforms and solutions. This software integrates seamlessly with the company’s display products to form a complete in-car experience solution, adding significant value for automakers seeking to enhance the functionality of their existing infotainment systems.
Through its innovative solutions for vehicles, LG is accelerating the arrival of the SDV era and playing a leading role in redefining the future of mobility.

Since the last webos update to 3.40.87, I find I have to completely power cycle the TV (a G1 65" OLED) every week or so to get the DLNA client back to functioning properly. I have a media server running Serviio on a Raspberry Pi, and I periodically get one of the following two problems, both of which are fixed by completely power-cycling the TV.
When I'm using the DLNA client to select videos from the server, I get no response from trying to select a video or series using the remote. The remote continues to work fine when used with other apps (eg Netflix, Stan etc) on the TV. When the DLNA client is playing a video from the server, the audio is delayed by a couple of seconds from the video. At the time that the TV is showing either of these problems, I can access the media server using either BubbleUPnP on my phone or VLC on my PC, and neither of them have any problem either selecting videos or playing them back with the audio synced with the video, so the problem is clearly with the TV, and power-cycling the TV gets rid of whichever problem is manifesting itself.
