HDMI control, aka CEC is the feature that runs over HDMI ARC or any HDMI port, to control volume on the AVR thru the TV remote or the Blu-ray menu and play functions thru the TV remote or AVR remote. You might need to verify with TV models on AVS Forum with your receiver model. I am not familiar with TCL but you may need to google it.
I don’t recall what version of HDMI first had CEC but most 2015 or newer gear should possibly have it. Samsung calls it, Anynet+. Sony calls it, Bravia Sync.
The catch is, the HDMI CEC can also automatically power on other devices and that can be annoying to some. For me I had to get used to it with my Yamaha AVR. So I need to expect that powering off my tv, also powers off my AVR to standby. I also need to be aware that powering off my AVR, doesn’t power off my TV though and that will give the tv sound thru it’s builtin speakers but the TV can still control the Blu-ray and Apple TV. Also, as soon as I power on my Blu-ray, everything immediately switches to Blu-ray
Upgrade your setup with web browsing smart TVs. Also if I power on the Apple TV, everything switches to that source. This is ok once you are used to it.
