If your budget is tight, you can go for TCL or Hisense mini LED TVs. I personally bought the Hisense 55-inch U7N last year. Bought a 3-year extended warranty from Reliance ResQ, so now it has 5-year warranty.
Then bought and tried multiple Budget Dolby Atmos 5.1 or 5.1.2 soundbars- Motorola, Zebronics, and Boat. and finally settled with boAt 5.1.2 Aavante 5500DA soundbar.
