Finally my TCL 75inch T7G arrived.
Some challenge need to over come then install.
1) Cut AC connector to UK adapter with fuse protection in case incoming power overload.
2) Need 2 person to lift up and install TV leg bracket or wall mount.
3) Difficult to initial setup TV due to need China phone no/ QR to activate TV (main difficult solved)
4) If with china apps account would be great.

Initial TV Feel/Feedback.
1) The black color really black like OLED TV and from black to gray to white the progress really good.
2) RGB color was really good very better then LG Nanocell maybe can say close to OLED TV.
3) It does not look dim in bright room as 1000nits screen.
4) Apps can be side load, Dont need google play & Netflix.
5) Youtube streaming with 4k 60fs can be done.
6) Sound quality of Onkyo is good can skip soundbar if dont have.

Done
1) Install artificial grounding on TV.

Future plan upgrade.
1) AC wire can be upgrade to hifi series power cable for better quality.
