What is your “favorite soundbar” for the LG CX (65″) tv? Thank you.
SONY HT-ST5000, SAMSUNG q70r, Q80R, Q90R
I’m using the “Rockville TM150C” speaker pair thru the optical connection on an LG TV. for $260 I’m quite pleased. When I upgrade to the 65″ CX I’ll build on the wisa connection with the Klipsch wireless speakers.
I do not see ATSC 3.0 or even ATSC 1.0 in this review. LG OLED 77 GX has an ATSC tuner and the CX or just about any other TV does not. I buy a new TV every 7 years or so and this will make it more future proof and I will not have another cable or box by this Gallery Flat to wall TV.
Good one the ATSC 3.0…hopefully someone in the know will respond.
I do see ATSC,QAM mentioned in the Digital TV Tuner specs sheet for the CX, but what exactly does it mean ?.
Will someone let us know.
