I remember when I first bought the TV in Nov '23, it would switch into PC mode (setting the HDMI input to PC) automatically when first connecting my RTX 4090 PC. This behaviour was fine as the TV was indeed being used for PC Gaming.
On my RTX 3050 HTPC I could disable PC mode by changing the input back to HDMI1. This would restore all picture settings options. This change would persist until the HDMI cable was physically disconnected/reconnected. Again, this behaviour was fine for my HTPC where I preferred having access to all the picture settings options vs 444 passthrough.
Now PC mode is reactivated after every Cold Boot (Shutdown > Power On) but not from Warm Boot (Restart).
It is a 'silent' PC mode as the input label does not change back to PC, however the same picture settings are greyed out like in PC mode. Switching the Input label from HDMI1 to another non-PC type disables PC mode again and restores the full picture settings.
I was using the RTX 3050 in my HTPC for a few months after I purchased the TV and did not experience this issue. After a few months I switched to the RX 7600 and continued to not experience this issue. I recently tried going back to the Intel iGPU on the HTPC and discovered this issue. I thought it might be an intel bug, so I reinstalled the RTX 3050 and found the issue again. I've gone back to the RX 7600 as it does not suffer this issue.
I have Game Optimizer options disabled (VRR, Freesync, ALLM), 444 Passthrough Disabled, QMS Disabled.
Intel and Nvidia GPU options tried:
Change output from RGB to YCBCR = no effect
Disable "Text Content Processing" on intel = no effect
Change "Content type reported" on Nvidia = no effect (Movie does activate film maker mode)
Also noticed that on the 3050 the TV switches to PC mode during POST (picture settings disabled in BIOS), while on the Intel iGPUs PC mode activates during Windows startup (picture settings enabled in BIOS, disabled at Windows login screen).
Testing performed on Win11 24H2, however also experienced the issue when testing LibreElec(Linux Distro for Kodi) on the intel iGPUs (didn't test Nvidia in LibreElec as unsupported).
Affected GPUs: UHD Graphics 730 on Intel i5-11400 and i3-12100, Nvidia RTX 3050
Unaffected GPUs: AMD RX 7600, Nvidia GT 1030
I've noticed that on the RX 7600 and GT 1030 the SPD Info Frame are blank/Unknown.
While on the UHD 730 - Product Description: PC, Vendor Name: Intel, Source Info: PC
and the RTX 3050 - Product Description: GeForce RTX 3050, Vendor Name: NVIDIA, Source Info: PC

To deliver innovative heating, ventilation and air conditioning (HVAC) solutions that are Ahead of the Expected, LG continues to push the boundaries of heat pump technology in cold climates. At AHR Expo 2025 in Orlando, Florida, the company showcased its energy-efficient solutions that enhance comfort while hosting a special roundtable on the Consortium for Advanced Heat Pump Research and its vision for the industry. Three LG representatives joined the consortium to bring their knowledge and insights to the table.
As climate change continues to cause major disruption around the world, the need for high-efficiency heating and cooling systems for all temperatures has been rising. Steve Scarbrough, senior vice president and general manager of LG Air Conditioning Technologies USA, joined the panel to highlight the advantages of LG’s heat pump technology in extreme climates. LG offers a wide lineup of heat pump solutions, including water heaters, boasting its cutting-edge inverter heat pump technology. What’s more, with the introduction of a highly efficient, oil-free inverter centrifugal chiller, LG now supplies 259,000 RT of chilled water to one of the largest data centers in the world. “We are excited to bring new products to market that are customized for all kinds of environments from single small spaces to large-scale industry settings,” said Scarborough.
Although heat pumps have traditionally been associated with warmer southern climates, LG’s introduction of its Inverter Compressor to the U.S. has allowed it to build a strong lineup of heat pumps that provide effective heating in cold climates. Moreover, LG has expanded its LGRED° (Reliable to Extreme Degrees) Heat Technology to more products, facilitating high-efficiency performance under more challenging conditions.
LG has successfully constructed substantial networks in heat pump solutions by investing in research and development and strategic partnerships with key industry players. For example, LG established the Consortium for Advanced Heat Pump Research with the University of Alaska network in 2023 to conduct real-life research and testing on various types of heat pumps.
Sunwoo Kim, professor of Mechanical Engineering at the University of Alaska Fairbanks, said the consortium focuses on minimizing thermal resistance in the outdoor unit’s heat exchanger to maximize heat pump efficiency. Researchers are also trying to uncover innovative ways to integrate heat pumps with existing fossil fuel boilers. “If we have a smart and well-designed hybrid system that optimally balances the heat pump with existing traditional systems, we could significantly reduce costs and carbon dioxide emissions,” said Kim. The University of Alaska’s cold climate heat pump labs in Anchorage opened last December, and is now testing heat pump applications in the real world.
The partnership with the Universities has already borne fruit. For instance, the first joint project with the University of Alaska Fairbanks has been largely credited for the LG Residential Cold Climate Heat Pump, which won the 2025 AHR Innovation Award. “The consortium aims to become the major hub of research and education in cold climate heating systems,” said Getu Hailu, associate professor of Mechanical Engineering at the University of Alaska Anchorage and faculty advisor for ASHRAE and ASME.
By constantly promoting deeper discussions to realize its vision for heat pump solutions, LG has once again demonstrated its unwavering dedication to breaking down barriers in cold climate heating while underscoring its status as the leading innovator of heat pumps.

Sooo that was a really long time since a release, but
link hidden, please login to view are still around and active as ever! We have continued making updates and producing testing images. But a lot happened that resulted in us not putting out a proper release out in the past few years.
Those who have stayed in touch with the community will know there has been some turmoil with the closure of the webOS Nation forums last year. Things stabilised over the last year as people converged around the and made plans on the associated . Much of the old information from webOS Nation was preserved thanks to the and can still be accessed, if imperfectly. We have now set up a that largely replicates the old layout and is ready for fresh content.
If you are eager to find out what we’ve been working on and to try out the new release, read on…
The (Jenkins) builder infrastructure we had available previously decided to have a number of malfunctions, leading it to be no longer available to us. So for now we’re back to our own builders for building all the images, which isn’t great, but at least we’re still building and providing images! We are now using , which means newer base components like systemd, pulseaudio and wayland.
Since the last release LuneOS has gone through a major rework under the hood. To summarize:
We moved from Qt5 to (6.5.2 included in this release). We have moved away from our own compositor (luna-next) to the one provided by LG in called luna-surfacemanager. We are now using LG’s WAM (WebAppManager) instead of our own custom one together with LG’s fork of Chromium (94). A major rebase of all components shared with webOS OSE to be based on the now. This included a migration to Enhanced ACG which provides a lot tighter security for LS2 calls from apps and services. This all was an enormous amount of work behind the screens but little visible to the end user, however this does offer clear benefits going forward being:
A shared code-base with LG, which means less custom components and maintenance. Years of field tested code on LG production devices which offers more stability. In this process we were able to keep backwards compatibility for apps and services. Easier to upgrade to latest OSE components, since we have migrated almost all remaining components that were still not based on the latest webOS OSE or on Open webOS. (125 components were migrated in total, 15 components are still to be migrated). In the meanwhile we have also been working hard to support the newly released devices such as the PinePhone, PinePhonePro and PineTab2 which are affordable devices which can run a very close to mainline kernel and a multitude of OS-es. We now support booting off on Pinephone.
The new close to mainline kernel for the Pine64 devices allows them to run things like out of the box!
All other supported Android devices are now based on 9.0.
So what is ahead for the near future?
Our focus will be on the mainline devices and emulator (), however we will try to keep support for the Android/Halium based targets as well.
Upgrade to latest Chromium 108 released by LG recently Work on audio & multimedia infrastructure provided by webOS OSE to get it working in LuneOS Work on camera infrastructure Try to get a mainline kernel working for Tenderloin, Hammerhead, Mido and Tissot. Improve/add QML components and add new basic apps to be used such as Camera, Flashlight, Audio Player, Video Player Piggyback off some of the work done by the . Provide a GSI image for newer Android (9.0+) based devices, this would allow a standard image to boot on most modern Android devices v.s. building a device specific one for each device. Known issues:
Battery usage is on the high side No audio in webapps (we decided not to spend time on this, seeing we plan to update Chromium soon anyway) The Usual:
Sign up for. Get involved and [ UPDATE https://pivotce.com/2014/09/22/webos-ports-help-wanted/ ] Feel free to download the updated builds to get started. Currently supported targets: PinePhone, PinePhonePro, PineTab2, Qemux86-64 (Virtualbox), all with mainline kernel. Tenderloin, Hammerhead, Tissot, Mido, Rosy, Mako (Android 9.0/Halium based with their respective Android kernels (3.4 and newer)). RaspberryPi 3 and RaspberryPi4 might work too, however we haven’t tested this ourselves.
. And remember we don’t do timelines.
Don’t forget to contact us with any questions and feel free to join the discussion on the . Catch us on Twitter @webosports on IRC: Libera:#webos-ports, or email [email protected].
We will see you shortly again with a new release!
