Just before 2weeks I buy this TV to my room, with my personal experence I would like to tell when I saw a program in my home hall TV( that is also 4k tv) the video quailty was very good when I see that program in this TV I felt some low brightness problem.So I think because of that the video quality feels low.Sound quality is poor beacuse it has very noisy speaker it doesnt produces a proper base & melody musicsThe value of money is very high when compared to quality of the productService is very bad there is no service center in our city. I hate this
