Samsung 55 Inch TV QLED 4K, Q70D, 100% Color Volume with Quantum Dot, 4K AI Upscaling, Samsung Tizen OS, Motion Xcelerator 120Hz, QA55Q70DA - 2024 Model - 1 Year Warranty (International Version)

I got this TV and only watch some 4K video and movies on It, picture quality is good and sharp.

Automatically on off I don't know why

Quick delivery and the packaging was really good. If you are going to assemble yourself, you might want to consider one more person to help you. It took me around 30-40 mins to install the stand and put it on a table. Picture quality is amazing, watching 4k videos are a treat. Since I paired it with my Sony home theatre system, I can't comment on the speakers. Overall it's a good choice if you want to set up a home theatre system in a small to medium size room.
