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.

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
