dont worry about Dolby thing.. what happens if screen is balnk with dolby sound on?? 😉 this may happen with TV's like TCL..it's just that Dolby Vision Atmos thing on TCL is appealing.
Screen is the most important thing to look for and then the rest later..
Look for Relame TVs also .. they are real value for money..
if you dont like this then go for LG.. thats it..
