For the OLED65C9PUA, does anyone have the measurements of the back for the location of the VESA mount? I am trying to figure out if my current mounting bar is too high for the tv to be able to fit.

The LG C9 55 inch Class 4K Smart OLED TV w/ AI ThinQ&reg; (54.6'' Diag), Model # OLED55C9PUA comes with an included LG Magic Remote which is a Bluetooth device. Unlike an InfraRed remote which requires a clear line of sight to control the TV, the LG Magic Remote will control the TV as long as it is pointed towards the TV and the cursor or pointer is showing on the TV...^IFV

I am having trouble figuring out how to control my television&rsquo;s volume using Apple HomeKit and siri. I have access to the on/off and input controls, but volume is missing. Any help would be appreciated. Thank you.

Asked by: ClarkK
The volume for the LG C9 55 inch Class 4K Smart OLED TV w/AI ThinQ&reg; (54.6'' Diag), Model # OLED55C9AUA does not respond to your Siri Remote or Apple Homekit device, you will need to manually program the remotes for volume control or turn on HDMI-CEC on the TV which is packaged as Simplink on LG TVs...^IFV
