How to know if UHD TV is Upscaling to 4K?


Pioneer123

Question

I have an LG 79UB980T-TA UHD TV that is fed from an Anthem MRX-510 amplifier generally displaying 1080p MKV files from Plex (via NAS).

 

The question is how do I know if the TV is doing upscaling to 4K or not, is there anyway to tell as just saying it does is a bit dodgy to me (being a bit sceptical sort of person!)?

 

Cheers

      Opening the web browser app, and going to photos.google.com shows a screen with a "go to google photos" button, but nothing works, the button does not respond and the only solution is to shutdown the whole tv, commander buttons do nothing.  64uq800006lb with latest firmware.

      First in the World to Receive ISO 13849-1 Certification for Mobile Service Robots,
      LG Confirms Its Leadership in the Field of Robot Safety Technology

      SEOUL, June 28, 2022 — LG Electronics (LG) has again proven its technological capabilities and commitment to creating safe, new innovations for a better life, becoming the first company in the world to receive the ISO 13849-1 certification* for its safety controller module utilized in mobile service robots. The new certification applies to LG’s advanced safety controllers for robots and was issued by Det Norske Veritas (DNV), an international accredited registrar and classification body headquartered in Norway.
      LG’s newly developed safety controller for robots ensures the highest level of operational safety and reliability by actively managing robots’ settings, monitoring signals from robots’ sensors in real-time and providing protective deceleration or stop-control whenever any risk is detected.
      Composed of only one module, LG’s safety controller boasts a significant advantage over conventional controllers – it can be easily adapted according to the individual specifications of each robot, or to meet the unique requirements of each customer.
      Previously, manufacturers had to analyze and evaluate every single aspect of functional safety for each robot they produced, but this is no longer the case thanks to LG’s sophisticated controller. This is expected to help the company authenticate and launch new service robots, such as those from its well-known LG CLOi ServeBot and LG CLOI GuideBot series, more quickly than before.
      A leader in the fast-changing robotics industry, LG has accumulated a wealth of data and knowhow through many decades of tireless innovation. The company has introduced a wide variety of robot solutions optimized for settings such as hotels, hospitals and restaurants, and leveraging its diverse technological capabilities, including in the areas of autonomous driving systems, sensors, artificial intelligence and cameras.
      Recently, the company announced its full-fledged entry into the next-generation logistics robot market with the launch of LG CLOi CarryBot, developed in collaboration with CJ Logistics, one of South Korea’s largest parcel delivery firms.
      “As autonomous robots for both industry and consumer applications are becoming more common, the field of robot safety technology continues to grow in importance,” said Dr. Baek Seung-min, head of the Advanced Robotics Lab at LG Electronics. “We are leading the way in this critical area, leaning on our considerable technological capabilities and real-world experience in applied robotics to provide the highest level of functional safety for the next-generation of autonomous robots.”

      I have a LG OLED C8 TV with a Soundbar and when connected to Optical the Volume Control is normal with a Percentage 0% to 100% but when connecting to HDMI ARC port like the Soundbar suggest to be connected it just show + or -,  you don't have anyway of knowing what the volume is set  to.    I have tried two Soundbars a LG LAS551H that was connected via Optical and when connected to HDMI ARC it also does not show Volume Control.  I have  got a new Sonos Beam Gen 2 that is now connected to HDMI ARC port and sounds great but if I connect it to Optical it's much lower in volume but has the Volume indicator.   Please advice.    
      I would like to suggest three enhancement request: 1. to show Volume Percentage on the HDMI ARC port.  2. Optical and HDMI ARC have the same output and 3. the Sonos be added to the Device list under Soundbars. 
      Thank you,
