Grainy screen

[Yaz17]

My Samsung tv screen is grainy when I’m watching normal tv but amazing quality when watching Netflix or Amazon prime. How do I make the tv quality better abs crystal clear

Its because most of amazon and netflix is in 4k or 4k hdr giving a far clearer picture but in normal tv its in hd at best thats why grainy. By playing with some of the picture settings you might get it closer to your own personal taste unfortunately its just the state of current broadcasting
