I have a Roku 3 I got 5 years ago. I understand this model came out 8 years ago. It has worked pretty well but recently I bought a great LG 75" TV and noticed that the picture quality when I view various programs through the LG interface is better and sharper. The Roku interface produces a picture that appears not to be as bright or sharp. I have the display set to 1080P. I use the Roku at night to connect my headphones. Are the newer Roku models better?
