I just couldn’t get comfortable in planes with my long legs besides the fact that I could never fall asleep on long, international flights. Luckily, I had no problems falling asleep on ships, especially when I was in the Navy!
I have a Samsung HDTV, recent vintage. You probably need to download the operator manual online. Most sets do have a hidden “button” that can do some basic stuff but most of the functionality comes from using the remote and is a tad more convenient, too.
A double doo.
